My sister and I, undeniably, had similar tastes. However, to my frustration she was luckier in love than me. Mark was her second serious boyfriend, and they’d been engaged a couple of months when she unexpectedly- but happily- got pregnant by him. Sometimes I looked at her growing belly and felt envious of that little kid for having such a handsome daddy. Mark was tall, beefy, and had a jawline you cut carve ice with. He used to have a ridiculous little moustache, but Sally had talked him into getting rid of it. She’d also helped him pick out a more impressive wardrobe than the polo tees and khakis he used to wear. Now he was a sharp dressed man, a confident talker, and worked out four or five times a week. I used to go with him to the gym, but I couldn’t keep up. I wasn’t exactly bad-looking either, but I was definitely a few steps removed from the muscley bear he was.

It was in the sixth month of her pregnancy that Sally phoned me up with an unusual request.

“I just can’t shake him,” she said in exasperation. “I know this is… weird, but he’s got urges I can’t help with anymore. I just want to sit down, put my feet up, eat pickled beets, and relax, but he’s…”

“Okay, what are you getting at?” I asked, dumbfounded. It surely couldn’t be what I thought she was getting at.

“I’m not a jealous person… well, not in general. But I don’t want to hand him off to one of my girlfriends, I couldn’t handle it right now with these hormones. You’re the only one I trust. He says he’d give it a shot.”

I stared at the phone in disbelief. “You want me to-”

“I don’t care what you do with him! Just… satisfy him, alright? When are you available?”

“Uh… send him over now, I guess.”

I ended the call and had a glass of wine. I couldn’t believe this was happening. It was kind of weird, admittedly. I’d known Mark for ages, thought of him more as a brother than a brother-in-law.

Mark showed up about an hour later, looking disheveled and confused. He sort of looked like I felt; like he could scarcely believe this was happening.

“Hey, bro. Let me take your coat.”

“Thanks,” he said, shrugging it off, and kicking off his shoes.

“Sally sent you over, huh?”

“Yeah, she sure did. Said she was sick of putting up with me. Said I should-” he hesitated.

“Said you should come over to get your dick sucked, huh?”

“Something like that,” he muttered.

“Well, unless you’re in a hurry, why don’t we chill out a little first?”

“Yeah. Sounds good.”

“Beer?”

“Yeah, please.”

We sat up on the couch in my living room in my dinky little apartment, him drinking his beer while I drank my second glass of wine. To say that it was awkward was an understatement. But as uncomfortable as I felt, I was also incredibly turned on and trying hard to hide my erection and the growing wet spot of precum on my crotch. He sat back on the couch, trying to look nonchalant, but not doing a great job of it.

“So… You ever had your dick sucked by a guy before?”

“Nah… but-” he paused, looked me in the eye. “I’ve fantasized about it before. A lot, actually. I’ve been really wanting to…” he cleared his throat. “You know, play around a bit. With other guys. Sally always said she wouldn’t mind. I guess I might be a little bit bi.”

“Nothing wrong with that. At the very least, you can let me suck you off, and if you enjoy it you can explore it again sometime. But if you decide it’s not your thing at all, you can just walk away and write it off as an experiment. I won’t be offended.”

“Uh… yeah. I guess.”

“Is that different from what you had in mind?”

He stroked his stubble. He looked like he hadn’t had his act together lately; in fact, there looked like a bit of a stain on his collar, and his hair was a mess. Married life usually suited him well, but right now he was understandably stressed out. I wanted so badly to help with that.

“I guess… well, I want more than just… you know, service. I’d really like to try… you know, all of it. Kissing, touching. See how I like it.”

“Oh wow. More than just a wham-bam, thank you ma’am.”

“Yeah. I know I could enjoy a blowjob from a guy, that’s just mechanics. I want to know if I’m really bi.”

I thought that over. I’d been with bicurious guys before. Sometimes it went alright, but sometimes it ended poorly. Having a guy text me to say ‘I’ve decided I’m straight after all, lose my number’ was definitely a low in my romantic and sexual career. But Mark was different, he was a good friend. A brother, even.

“And if you decide you’re not into guys? Is this going to be awkward?”

“No. I don’t think so. It’ll only be awkward if we let it be, right?”

“Alright.” I walked off, grabbed a bottle of oil from my bedroom, and returned to the living room. I sat down, grabbed one of the overstuffed pillows off the couch, and dropped it on the floor between my legs. “First things first. You look so tense. Come sit down here and let me rub your shoulders.”

He didn’t hesitate at all. Regardless of what else we were going to do, he really needed this. I spread my legs wide to accommodate his broad frame, warmed up some oil between my hands, and started working on his neck and shoulders. Within moments he was letting out a soft whimper, but as I found his knots and got to work on them, he gave me some good grunts and moans.

“This will be a lot easier if-” I started, but before I could finish he was already pulling off his t-shirt.

I’d seen him shirtless before, even naked, in locker rooms. But it was different having his bare flesh under my hands. I had to adjust my pants to accommodate the aching erection there. His hard muscles gave way and relaxed as I worked the peppermint-scented oil into them, and he couldn’t hold back to the noises of pleasure as I went.

Eventually I could feel that my hands had enough, and were threatening to cramp up. I gave him one last rub, admiring the look and feel of him, and got up to wash the oil off my hands.

When I returned, he was standing there awkwardly, holding his shirt, like he wasn’t sure if he should put it back on. I smiled and grabbed a towel, wiping the remaining oil off his back. He smiled.

“Thank you. That felt incredible.”

He was easily a good five or six inches taller than me, but he was trying his best not to loom over me. I didn’t mind though. I was loving that big-brother vibe. I looked up to him and smiled.

“Kiss me,” I told him.

“I’m not sure if-”

“Just do it. Think about it later.”

He shrugged, and leaned in. His lips met mine, and I felt his stubble brush my face. I loved the masculinity of it, but it was coarse too. His lips were tentative, like he’d never kissed anyone before.

I put my hand on the back of his neck and pulled him in closer. I wanted him, needed him, and he had to show me that he needed me.

He kissed back a little firmer, following my lead. I felt his hand on my shoulder, holding me close. His lips moved against mine, finding the lead, showing some hunger. I brushed my tongue against his lips, an invitation. He took the invitation, meeting my tongue inside my mouth, showing some dominance. I felt light-headed, and could feel my heart pounding.

Finally, he disengaged, pulled back. He was smiling.

“Okay,” he said. “I liked that.”

“Damn,” I replied, catching my breath. “You’re a good kisser. My sister is lucky.”

He blushed a little. “Thank you.”

He showed some assertiveness now. He put his arms around my shoulders, pulled me in close, and kissed me again. This time there was uninhibited passion behind it. I felt his hand on the side of my face, brushing tenderly over my cheek. The mix of passion and gentleness was exhilarating. My hands started exploring his torso, up his sides and over his chest, enjoying the shape of him. He was strong and muscular, and I could feel him tensing and relaxing as he held me.

His hand wrapped around the back of my head and held me tight. The masculine dominance of his movements was driving me crazy. The man had some real style and personality when he let himself relax and enjoy it.

Finally he pulled back from the kiss, and pulled my head onto his chest, holding me close in a tight embrace. I heard myself let out a soft sigh as I felt his thickly furred chest against the side of my face. I could hear his heart beating fast from the anxiety and excitement for this new experience.

“How are you feeling, brother?” I asked.

“It feels good. Now that it’s actually happening I’m… excited. It feels really natural.” He ran his thick fingers through my hair. “I want you.”

“Okay. How about we go to the bedroom?”

“Yeah. Let’s do that.”

I led him to the bedroom, smiling with joy. I hadn’t foreseen this night like he had, but now that it was here it seemed like the right thing to do. The idea of releasing his pent-up sexual tension was exciting. The idea of initiating him into man-on-man sex titilated me.

In the bedroom, I reminded myself to take it slow. I ran my hands over his firm muscles. I enjoyed the ledge of his pecs, the crease of his armpit. I asked him to flex his biceps for me, and rubbed my cheeks against them and kissed them.

The smell of him was wonderful; his cologne has some kind of woodsy scent to it, like cedar or sandalwood. It suited him really well. It mixed with the smell of his sweat and the massage oil into a wonderful heady aroma.

He kissed me again, and started undoing my shirt. I got shivers from feeling his strong, thick hands undressing me. I could tell that my bare chest was new territory for him; he was hesitant but excited as he caressed my skin. He didn’t seem to know what to do in the absence of breasts; he brushed my nipples with the backs of his fingers, which gave me an electric shock right down to my groin. He was moving on, but I grabbed his wrists and led him back. He gently brushed them, played with them, pinched them. I moaned and whimpered; he was driving me crazy. I saw a look of fascination on his face; he apparently didn’t realize that men could enjoy this treatment too. I reached up to play with his, which elicited a surprised expression. He melted a little, obviously enjoying the treatment. We played with each other’s nipples for a few minutes, taking our time to enjoy and explore the sensations.

“Nobody’s ever done that to me before,” he sighed.

“Most men are afraid of it. They think it’s emasculating.”

He laughed “Well call me a sissy, just don’t stop.”

I laughed. I pulled his face down and gave him another kiss, enjoying the feeling of his bare chest pressed against mine. He wrapped his arms around me and rubbed my back, then down to my ass. He reached in under the waist of my pants and gently fingered my crack.

Feeling his body pressed up against mine, the passion and desire in the way he treated me- it was nothing at all like I expected. I had thought he would sit back on my couch fully dressed, his cock sticking out of his fly, and watch straight porn while I sucked him off. This wasn’t like an encounter with a sexually repressed straight guy, it was like an encounter with a lover.

I undid his zipper. In the process I brushed up against his hard member tucked away in his pants, with a small wet spot forming. He was definitely enjoying this; his cock couldn’t lie. As his pants fell to the floor I started stroking his stiff cock through his cotton briefs.

“Aww fuck. Nobody’s touched me there in weeks.” He shuddered like he’d been shocked with electricity, and his eyes rolled back.

I gave a small laugh. “Well, let’s make up for it.” I knelt down and pulled his briefs down, exposing his cock which bounced to attention. It was right at eye height, and I had to back away to avoid getting hit in the face. I was shocked. I knew Mark was well-hung; I’d seen him in the showers at the gym before, but I had assumed he was a shower. Nope, he was a grower: he went from a dangling five inches to a generous nine, maybe ten. Fairly thick, too. The bulging head of it was like a plum. I prided myself on being able to take huge cocks up my ass, and even dabbled in some stretching and a bit of fisting, but this would still be challenging without some preparation. Not that we were going there- not today, anyways. The worst part was, I was worried that I wouldn’t be able to deep-throat him. I’d rarely met a cock I couldn’t get down my throat, but this was different. I’d be damned if I wasn’t going to try my best, though.

Mark was leaking precum like a broken faucet. I scooped up some with a finger and brought it to my lips, getting a good taste. It was delicious; salty, but not too bad. He was probably well hydrated. I looked up at him. He was watching me with fascination. This was about to be a first for him; I wanted to make sure I did it justice.

I wrapped my hand around the base of his cock, a reassuring firm grip, and aimed it towards my mouth. I took him in slowly, carefully, wetting him between my lips and tongue, playing with the underside of his shaft with my tongue. He tasted fantastic, probably one of the best cocks I’d ever taken. There was a pleasant sweetness to him. Now I was even more determined to bury his entire bone in my mouth.

He gave a satisfied little moan as I worked his cock slowly back and forth through my lips, getting further and further towards his crotch with each stroke. I saw his trimmed bush growing nearer and nearer. I sucked hard, angled my neck as best I could, and kept going. It was hard to stifle my gag reflex when his thick, pulsing head was pushing up against my throat, dribbling that delicious precum everywhere in my mouth. But I was determined.

As I was getting closer, I felt his hand on the back of my head, encouraging me but not pushing me. I didn’t want to disappoint him. Hell, if I could manage it, I would practically beg him to just grab my head and fuck my mouth like a whore. I grabbed his firm, muscular ass cheeks in my hands and pulled harder, trying hard as hell not to let my throat muscles seize up and reject his cock. I struggled through, and was rewarded with his crotch making contact with my nose. My eyes were watering hard. I felt his hand gently push me even further, felt his cock stretch open my throat. I had no idea he would be this assertive, and I loved it. I heard him sigh contentedly.

I stayed there as long as I could, but finally I had to pull back with a puff of air as I gagged. I looked up at him through eyes so full of tears I could barely make him out, but I saw him smile.

“Fuck, little bro. That was hot! Nobody’s ever taken that much of my cock before.”

I tried to answer, but stuttered and gasped through a throat coated with thick saliva. It was dribbling down my chin.

“More,” I begged. “Please.”

Then his cock was being thrust back into my face, and I gulped it back happily. He started fucking my mouth, slowly at first, making sure he wasn’t hurting me. But I grabbed his thighs and pulled him closer again, and he took the hint. He started pounding my face good, using me for his pleasure, and I loved it. I choked and drooled around the shaft of his cock as it fucked my throat, but I just encouraged him to keep going, grabbing on to his thighs and pulling him closer.

He withdrew finally, and I was panting. He was thoroughly enjoying himself, but he wasn’t ready to stop yet.

“Let’s have some more fun. There’s something I’d like to do… something that drives your sister crazy, and I bet you’d love it too.”

“Oh?” I was nervous, but thrilled that he was starting to take control. I was ready for whatever he wanted to bring to me.

“Get up on the bed. Ass up in the air.”

I did as he ordered without hesitating. He roughly pulled off my pants and underwear, and it was a strange thrill to be exposed to him like this. My balls and cock dangled in the air, teasing him. He wasn’t interested in those, though. At least not yet. I was about to interject, worried about whether he had the go-ahead from my sister to do what I suspected he was about to do.

But then he grabbed my waist and pulled me upwards, towards his face, and without warning I felt his rough stubble in my ass crack and his tongue darting into my hole. It happened so fast I spasmed uncontrollably, then consciously willed myself to settle in and enjoy it. And it was thoroughly enjoyable; he obviously had gotten a lot of practice eating ass. He darted the tip of his tongue in and out of my hole, digging deeper with each thrust, then paused to lick around my hole and kiss my cheeks. The tickle of his stubble was driving me crazy. I moaned with every little movement he made; he was driving me crazy. That wet, firm feeling of his tongue flicking my hole was making me crave even more, but he was taking his time. He was obviously loving this, and I had no problem letting him get his fill.

“Oh fuck… oh God, Mark, that’s…” I could barely speak, I was so lost in the amazing sensations of it.

To my surprise, I felt one of his hands grab me firmly around the cock and balls, and start to tug. He was losing his inhibitions quickly, maybe because he knew how good he was making me feel and it made him feel in charge. I felt his saliva running down from my hole towards my crotch, and he made use of this as lubricant to start jacking me off. Even a straight guy can give a decent enough handjob if he had to; most of them had the experience. He wasn’t perfect, but he was doing a good job and making me feel so incredible. I felt his fingers and palm wrap around my shaft and stroke me all the way down to the head of my cock. I buried my face deeper in the bedspread and moaned, totally lost in pleasure.

Then, he finally pulled his face away, and at first I felt lonely and empty, desperately wanting him to bring his tongue back or replace it with that magnificent cock. But he had other ideas.

“I want you to sit on my face,” he said, lying down next to me on the bed.

“Are you sure-” I was asking, but then I saw the greedy look on him. He certainly didn’t have to tell me twice. I quickly straddled him and brought my ass down on his mouth- not quickly enough for him, because he grabbed me by the waist and pulled me roughly down. As his tongue slipped into me, I let out a groan. One thing about straight men, some of them are very experienced with their tongues. I may have been on top, but he was in control, and he was pulling me down harder on his face. That tongue was fucking me better than half the cocks I’d had inside me. I started riding his face, pushing my ass up against his mouth, moving like I had a cock inside me. I heard his muffled moans of appreciation; he was loving this as much as I was.

Then my attention turned to his beautiful big dick in front of me. I leaned over and started sucking on him again. He propped himself up with a pillow to get a better angle on my ass, and started munching away again vigorously as I took his cock in my mouth. At this angle, I was able to more easily get it down my throat, and I buried my nose in his balls and enjoyed the sensation of being completely filled by it. It was so hard to stifle my gag reflex around that thick, rock-hard cock, but it was so worth it. Feeling his entire cock lodged in my face and his talented tongue reaming out my asshole, I was in absolute heaven.

We stayed there for a while, pleasuring each other in this wonderful position, until he decided he’d had enough. He gave me a gentle pat on the shoulder, and I pulled off his cock with a gasp.

“You okay?” I asked, barely able to speak.

“Yeah. Just… let’s slow down. Enjoy this. Is that okay?”

I laughed. “Of course! Take as much time as you want.”

So he laid back in my bed and pulled me to him, and laid my head on his chest. It was wonderful being naked with him like that, and I loved the cuddling, but part of me was worried that he had reached a point and changed his mind. He started to gently stroke me and kiss the top of my head, in a very warm and loving way.

“You okay?” I asked.

“Yeah. Very okay. I can’t wait to explore some more, see what else we can get up to.”

“I’m so glad to hear you say that.”

“It’s strange… I didn’t really expect you to taste so different. I’ve never tasted a man before.”

“Huh. I never thought of that. Was it alright?”

“Yeah. Actually, I think I really liked it. I liked kissing you, too. And fuck, you give amazing head!”

“I’m glad you like it, big bro.” I gently ran my fingers over his chest, and started absentlly playing with his nipple. He gave a little gasp, and started rubbing my back.

“Damn, that feels good. Why don’t chicks play with guy’s nipples?”

“Because lots of guys would be offended.”

“I guess. That’s just stupid though.”

I started licking his nipples, playing with them with my tongue. I could feel his hands on my shoulders, urging me on. I slowly sucked and licked his nipples, aware that I was probably pushing him into the next stage of this encounter. He put up no resistance, though. I could tell he was really enjoying it. His cock, which had relaxed about halfway while we cuddled, was getting hard again.

“What else are you going to show me?” he asked, smiling. I looked up at him.

“Hmmm. Well, my ass is all yours if you want it. And if that’s allowed… I don’t want to make any drama between you and Sally.”

He was already shaking his head. “We talked about it. Nothing’s off the table.”

“I’m really happy to hear that. You ever done anal before?”

He grinned. “Yeah, I have. I’d love to try out your ass, see how a guy compares.”

“I’d love that.” I played with his cock and his nipples some more, wanting to get him nice and hard. “What kind of positions do you like?”

“Dunno. I think maybe I’d like to see your face when I go inside you for the first time. Would be great to see how you’re feeling, make sure you’re taking it alright. Most chicks can’t take my cock at all, let alone in the ass.”

“I can take it. It’ll be a stretch, but I know I can take it. Just go slow, to start.”

I laid down on my back and grabbed the lube out of the nightstand. He knelt below me, fingering my ass, while I rubbed some lube into his big thick cock. I was feeling a little nervous, but I knew I could take him. I wanted it so desperately, and that always helped.

He pushed the head of his cock up against my hole, and looked me in the eye.

“Ready?”

“Yeah.” I pulled my legs back, giving him the best angle I could. I felt his cock head push against my hole, slowly encouraging it to open. I took a deep breath. My hole slowly relaxed and let him in, and I thought it was going to slide it just fine- but then I felt that thick head pop into me, and I gasped.

“Oh god- oh, fuck. Stop for a second.”

He looked at me with concern. “Want me to pull out?”

“Absolutely not. Never. Oh fuck… I just need a minute, hold right there while I get used to it.”

He nodded, and gently ran his fingers through my hair. It was such a sweet, reassuring gesture- not the kind of thing many men did. It felt good, though. I felt my body relax as he treated me with that gentleness. We made eye contact, and I nodded. He slowly thrust his hips forward, inch by inch, watching me to make sure I was alright.

I was far beyond alright, though. He was moving slowly, but he felt even thicker than I thought, and it felt like he was slowly stretching me open to my full capacity. Maybe I was nervous, maybe I wasn’t as mentally ready as I thought, but his cock inside me felt like a fist. He kept going and going, slowly sliding inside me, watching for my reaction. Holy fuck, there was so much of him!

“Wait,” I breathed. “Give me another minute. How far in are you?”

“More than halfway,” he told me.

“Okay. Fuck, that’s deep. Can you… your angle, can you-” I wasn’t sure what to ask for, but I made a gesture and he seemed to understand. He lifted himself up, angling his cock downward a bit, and I felt something inside me give way to him. I moaned.

“Yeah. That was it. Holy fuck, that feels good. Give me some more.”

He continued to slide into me, and I nodded encouragingly. Finally I felt his crotch press up against my ass, and I realized he was all the way inside me. I felt embarrassed; I knew I’d taken more than this, but he felt like the biggest cock I’d ever had inside me. My legs shook and I felt a shiver go through my whole body.

“Feels okay?” he asked, stroking the side of my face.

“Yeah. Goddamn. Thank you, bro.” I kissed his hand. “Just… go slow, okay? To start. It’s so intense.”

He nodded, and slowly pulled out a few inches. Immediately I wanted him all the way back inside me; I needed him. He pushed back inside, and it felt incredible.

He fucked me like that for a while, gentle slow strokes, nice and shallow. I swear I could feel his cock moving around deep inside my stomach, pressing up inside me. I felt so right, I never wanted it to end.

Once he saw that I was taking his cock well, he started thrusting deeper and faster, angling from a higher stance and looming above me. It was ecstasy. I think I might have been sweating. He leaned down and kissed me, and pushed even deeper inside me as he did it. I moaned; loving the experience of having his tongue and cock inside me at the same time.

Seeing that I was doing alright, he started giving me more. Harder, faster, longer strokes as his cock pulled out and reamed back into me, so deep it felt like he was trying to fill my whole body.

“Oh fuck,” I swore. “Oh god yeah… give it to me good. God damn that cock feels so good.”

That unleashed something hin him; he was fucking me with aggressive fury now, growling and sweating, slamming that huge cock into me over and over. I felt like I was going to burst.

And then I did, unexpectedly. I felt my cock twitch and unleash spurts of cum onto my stomach, adding to the puddle of precum already there. I moaned and threw my head back. My hole gripped him tightly in little spasms as I continued to come stream after stream without even touching myself. This must have put him over the edge, because I saw him screw up his face and let out a growl, the rhythm of his strokes falling apart into a chaotic deep thrusting as he filled me with his cum.

He collapsed onto me and I held him tight, feeling his cock give a few last twitches as his orgasm subsided and the last of his load rushed into me. I held him as he caught his breath and his cock slowly went soft inside me. I tried my best to milk every last drop of him, determined not to let it go to waste.

Finally his limp cock slid out of my hole. He rolled over onto the bed beside me, and I curled up next to him. He wrapped his arm around me and held me tight, and we both just lay there for a while, enjoying the afterglow, catching our breaths. I found a mirrored puddle of my cum on his belly from where he’d laid on top of me, and I absently ran a finger through it and took a taste.

He watched curiously. “What does it taste like?”

I smiled. “What, you’ve never tasted your own?”

He thought about it. “Actually, no. Never really been curious.” He scooped a bit of my cum out of his belly hair with a finger, and brought it to his lips. I watched, a little worried. I love the taste of cum myself, but it’s not for everyone.

He smiled. “Not bad. Maybe next time I’ll suck you off.”

I smiled back. “So, there’s going to be a next time?”

“Yeah, for sure. Give me a few minutes and let’s go again.”

I laughed and curled in, enjoying the warmth of his body, his presence. He could make me his regular fucktoy and I’d be deliriously happy. I started hoping that my sister decided to have a large family.
