(Part 1 Here)

As I follow my sister-in-law into the bathroom, I see her hook her thumbs in the waistband of my old boxers and when she passes the doorway, she bends forward, sliding them down.

"Jesus," I breathe out. She looks back at me and winks. I step into the bathroom and close the door. She's turning on the hot water before lifting her shirt, well, my T-shirt, off her body in the way with the criss-crossed arms that raises the whole thing from the hem at once.

"So did she tell you all the buttons to push or are you just lucky?"

"Who me?" she asked, batting her eyes.

"Very funny," I said, hopping up on the vanity top. She sauntered over to me waiting for the hot water. I hadn't seen her fully naked before, let alone hips swaying as she approached. I didn't try to hide my looking. Her hands rested on my thighs, sliding their way up to my waistband.

"C'mon, lift yourself up," she said, sliding my pajamas and boxers down, my swelling cock springing up. She wrapped her fingers around it and looked me in the eye. "Touch, but no cumming, yes?"

"Yesssss," I hissed, leaning back into the wall.

I felt her hand leave me and I see her walking into our shower. I was patting myself on the back for getting the glass shower walls installed last year, as she stood under the streaming water.

"So free passes, eh? Let's see. Okay, I'll give you two this week. You just send me a message and tell me you're going to use it and I'll leave you alone for the next four hours. But they're just to use with L. Not for you to jerk off thinking about my soapy breasts." As she had been talking, she had been working up a thick lather as her hands moved across her chest. "Hello?"

"Uh," I stammer, snapping my eyes up to hers. "Yeah, got it. Message you, I get four hours. Only with L."

"Good boy."

I had to drop my hand off of my shaft, as I had been approaching the point of no return.

"Seems like a shame, though. Sounds like you've been making her happy without it. Makes you think."

"Uh huh," I say, unable to pull my eyes off of her ass, which was now the focus of her sudsy hands.

She tells me to come closer, as the glass wall is fogging over and I stand near the open end of the shower. She was rinsing the shampoo out of her hair. As she finished, she came towards my end of the shower and knelt down, looking up at me, wet and naked.

"I'll give you to the count of thirty and we'll see if you get there," she said, before parting her lips and drawing my cock into her mouth. She kept eye contact with me as I felt her tongue playing across the underside of the head. My knees weakened and I braced myself against the tile wall. I can hear her saying something around my girth.

"D-don't talk with your m-mouth fu-u-ull," I try to joke. She drops my cock out of her mouth.

"Twenty-eight, twenty-nine, thirty. Looks like your smart ass cost you. And I'm all clean, so get out of here so I can get dressed."

I hand her a towel and take my time, watching her dry off, before she kicks me out. I go back to my room to get dressed. As I drop down my pajama bottoms my dick springs up, still fairly hard. Why not? I think and begin to stroke myself. A minute later I hear the door, look over my shoulder, and see my wife and C. walking in. I drop and try to pull up my pajama pants, but bungle it and they both get an eyeful.

"Jesus, Eric! We have guests in the house." She turned to C. "I'm so sorry you had to see how much of an animal my husband is."

"Oh, it isn't the type of thing I haven't seen before," she said, smirking at me in her towel.

They left so I could get dressed and headed down for breakfast. Alone in the kitchen with L. she gave me a hard time: "What's gotten into you lately? Can't go a whole day without playing with yourself?"

Luckily C. gave me a rest for the morning and through lunch. I had wanted to get a run in this weekend, so headed out for a quick few miles after my lunch had settled. By the time I got back, sweaty in my T-shirt and running shorts, I noticed our vehicle was gone. I came inside to a quiet house.

"Hello?"

"They went to a kiddie movie," said a voice from the couch in the dark living room. It was my oldest nephew. He was on his phone, not looking up.

"Oh, okay. I'll grab a shower and then let me know if you need anything."

"Uh-huh," he said, eyes glued to the screen.

I hop into the bathroom, peeling off my sweaty clothing, letting the water warm up. Just as I step into the shower, the door opens.

"Hey, I'm showering in here!"

"I know," said a feminine voice. I breathed out, realizing I had just assumed C. had gone with L. and the kids.

"You scared the shit out of me."

"Stop complaining. I'm just here to give you a task."

"Uh, what?"

"I remember L. going on about how you shaved in college. How much she liked that."

"My beard? I haven't been clean shaven in a long time."

"What? Oh, no, not that." She walked to the edge of the shower glass, reaching out to cup my balls. "These."

"Oh!" I said, honestly surprised, and starting to grow in her hand.

"So you should shave those while you're in here showering."

"Um, okay, sure."

"I think I should stick around to make sure you don't forget." She now takes her turn sitting on the vanity top. I can see her thighs pressed together, squirming slowly.

"So to get the best shave, I need to, ah, get close because it pulls everything tight."

"Go right ahead. Don't mind me. You certainly seemed to be free with masturbation this morning in your bedroom."

As I began to suds up and stroke myself to hardness, I asked if she did that on purpose.

"No, it was actually an accident. I was surprised that L. was up here and she had a top I wanted to borrow, so I was following her into your room. It was fun to see your ass clenching as you jerked off. I might ask you for some video of that this week."

I groaned.

"Speaking of which," she said, pulling out her phone. "Time for a fresh video for r/Shower_nsfw. Get shaving."

For the next few minutes, she knelt near the shower as I gave my boys a shave and a hair cut (two bits!). As I finished, she put her phone down.

"Wow. That is a difference. Rinse off and come here," she said, staring.

I do, stepping to the edge of the shower. She grasped my shaft with one hand and ran her fingers under my balls with the other. She gives me a few experimental tugs and giggles as I shiver.

"I forgot how much more I can feel like this. Jesus."

"Well, good. Enjoy. We're taking off today. Ah, don't be sad. That's cute. Don't forget you have the freebies to use this week. But don't forget to tell me ahead of time."

She left me alone to finish my shower and get dressed, for once. Shortly after L. comes back from the movies with the kids, C. and her brood pack up and get on the road. We were busying ourselves with dinner preparation, when L. leaned over to me.

"C. said you have a nice ass."

"Oh god," I said, feeling blood flow starting below.

"I couldn't believe you were doing that when we walked in." She started laughing. "You came last night. What? Did you just wake up in the mood?"

I just nodded, blushing.

"Well I was thinking we head to bed right after the kids." I looked at her with raised eyebrows and a smile. "We can do that thing you like."

"Really?"

"Uh huh. You were so helpful this weekend. I hope having my sister here wasn't too hard on you."

I nearly spit out the water I was drinking at that.

I couldn't wait for dinner to get over and bedtime to be done.

Redeeming a freebie tonight.

Throwaway8956859 8:15
I mean, if you want to burn through one already. Don't forget, you only have two.

phasma_sum 8:16
Nope, for sure tonight.

Throwaway8956859 8:17
Okay, you have till just after midnight. I won't bother you till then. Have fun!

We brush our teeth and I head into the bedroom. Scrolling a little on my phone as I wait for L. to join me. I'm already semi-erect in anticipation. It takes longer than I expect, so I call out to ask what's up.

She wanders into our bedroom, staring at her phone. I hear a ping.

"Who's messaging you this time of night?"

"What? Oh, it is C. She has a quick legal question." To herself: "Oh my god, what? Hmm." To me: "One sec., I am going to just call her. It will take five minutes and then I'll be done. Quicker than texting."

I groaned.

"Oh don't be so dramatic. I'll be right with you." She sat down next to me and slid her hand over my stomach, sliding below my waistband and grabbing my hardening shaft as she dialed the number with her other hand.

"Oh, anticipating much?" she asked and then put the phone to her ear. "What? Oh, hi. Anticipating? Yeah, we were just about to watch a show and Eric was anticipating it. Uh huh. Sure, what's up?" She and C. talked about a minor legal issue she was having at work. After a few minutes the talk turned to a rehashing of the weekend.

"We just spent the whole weekend with them, c'mon," I whisper. Her hand comes out of my shorts to make the hush sign against her lips. Her hand doesn't come back as she and C. get deeper into their conversation. They range over topics from the weekend to kids in school and their parents. Before long I'm nodding off. I seem to hear L. telling C. that "yeah, he's just dozed off. You owe me," but I was in and out and then just out.

I woke with a start into a dark room. I could hear L. breathing evenly next to me. I blink my eyes until I can see the clock: 1:03 a.m.

"Goddammit," I say out loud, sighing. I grab my phone and fire off a message.

phasma_sum 1:05
You said you would leave me alone for the freebie!

No answer, so I touched myself thinking about what I had been hoping to do with L. until I fell back asleep. It was my little protest to think about L. instead of C. for her deviousness. That'll show her. As soon as I woke up, I grabbed my phone.

Throwaway8956859 7:02
Oh boo hoo. Read the fine print. I said "I'll leave YOU alone for the next four hours." Never said I wouldn't interfere at all. Did you have a good sleep?

phasma_sum 7:03
I fantasized about L. instead of you for the first time in a week...

Throwaway8956859 7:06
[A video comes through, showing C. draw the phone down beneath the covers. She's wearing a tight, white tank top that does nothing to hide her nipples as it hugs her breasts tightly. The camera precedes down to show her in my boxers and her other hand is already below the waistband. I can see the material moving rhythmically. She is sighing and whispering my name.]
Good for you. Now go to the bathroom and send me a video when you get close watching this video. No cumming for you. You have five minutes or you lose your last freebie.

phasma_sum 7:08
Jesus. This is going to be a hard week.

Throwaway8956859 7:09
You have no idea.
