It’s the day after Christmas. 3 days after I stole my aunt’s panties. 2 days after my cousin found everything out and just a few hours before I was taking his surprisingly thick dick. We had just gotten to his house where I was going to spend the next couple days before I went home for New Year’s Eve. We decided to come over because our grandparent’s house was now full of guests and we gave up our aunt’s room to other family. We have the house to ourselves for the night as his parents were visiting his other side of the family a few hours away. And for some reason he really wanted to stay to “hang out with itsinthepeach since we don’t see each other as much.” In the bathroom inside I was wearing panties and a cute sheer chemise I swiped. I planned on returning them before I left, but for now I was enjoying the set. I kept the panties on but packed up the chemise. Then I showered and returned to my cousin’s room where we had a movie going and planned to watch some of our favorite porn.

Not even a few minutes into it, Nick asked me if I was wearing panties. I confessed that I was. Some sheer black cheeky panties with black hearts on them. I wasn’t shy about what I was going to keep after the second panty raid we did. He chuckled and we continued watching the cinematic masterpiece of a lucky delivery guy arriving to the right house at the right time. My cousin, Nick, commented that he would really like to try doggystyle with a girl. He had only ever done missionary. What I hadn’t realized is that every night I was sexting Mark and Andrew, my mind didn’t have a chance to restart really. I would reread our messages through the days and I could not help swelling up and leaking constantly. An image of myself bending over to teach Nick how to properly fuck a girl flashed in my mind. In my mind I also had long hair, smooth flat breasts jiggling and my clit flopping around leaking. On the screen, the delivery guy is balls deep in the hot Latina bent over a couch. Nick is already at it. I’m gently massaging my ass pussy that I cleaned and shaved in the shower. One finger in and Nick gasps, “Are you fingering your self dude?!” I nod yes and ignore him as my body transformed into the woman’s body on the screen. I was her. Willing and begging for it. I look over at Nick. I’m just a girl that happens to be in the same room as him. And he’s just a guy with pent up sexual frustration.

“Do you want me to pretend to be a girl for you?” The words come out of my mouth. With my own two fingers inside me and Nick tugging on his hard cock just feet from me on his bed watching the screen. He turns wide eyed to me and just says, “Okay. Teach me how to fuck a girl from behind too.” I’m immediately on my knees in front of him. I pull the cover off and expose a hard cock. It wasn’t funny or a prank anymore. There was just a hard uncut cock about six inches in my hands and I was just a girl hooking up with a guy. He tasted good. His cock was trimmed well and I was impressed with how much of my throat it filled. I bob my head up and down. He’s saying the most satisfying phrase to any sissy, “ohhh that feels so good.”

I tell him to lay down on the edge of the bed. I grab the blue chemise from my bag and strip down to my panties. My cousin slaps my ass and we both laugh. I pull out my wedgie as I straddle him reverse cowgirl. “I didn’t know you shaved your legs,” he says as he caresses my calves. As I give him my signature lap dance, I can’t help but feel some gut feeling. A feeling of cheating on Mark and Andrew. I couldn’t understand it. Had I gone this far down the rabbit hole? That I even had these feelings? And I was so desperate to take any chance at cock that I would even fold to my own cousin? I was too far at this point. It wasn’t who I thought it was rubbing against the lace of my panties. I was a horny girl. And he was a horny guy.

Five months after the night I taught my cousin, Nick, how he should fuck a girl, I was back in town for one month. A usual occasion every summer. And for six weeks like clockwork my aunt was out of town with her friends from work on vacation. Her room and dresser was all for me. Nick got out of school two days after I arrived. He walked into the house with a suitcase and told me he’s going to stay the entire summer. I was only there a month, but what we planned had worked. When I returned home last time, Nick was texting me constantly about the experience. He had several videos on his phone. “I just wanted to ‘study’ later” was his excuse when I looked back to see him focused in on his phone recording his cock going in and out of me. I received constant praise from him for about a month. And then it went back to normal chit chat and online gaming. But closer to summer, we planned an opportunity to “try it” multiple times. And the first night, the plan came to fruition.

During the panty raid, Nick picked out an entire outfit for me. White cotton panties, an underwire white bra, pajamas with hearts and “love” all over them, and I packed two wigs that Mark let me barrow from his sister’s costume bag (I promised him it was just so I could send him pictures over summer break). Nick chose the long wavy purple wig. I dressed up and asked him what he wanted to try this time. That maybe I can teach him how to fuck a girl a new way. He requested a blow job. I think it was 10 minutes later, he says those magic words, “I’m about to cum.” And he did. In my mouth. While I was away the first night I would give him a blowjob and swallow. He had never experienced it before.

We took a couple days break and had plenty of time to plan. It was decided. I was to role play as his girlfriend every night. Sex or not he was groping my ass in panties and rubbing himself between my cheeks. It’s as far as he would go besides a blowjob. But I wanted more. So I started to pull my panties down. Night by night I was prone with my ass in the air gently inching his cock inside me. Until finally he was stroking in and out of me slow and deep. My aunt’s thong fitting my naturally feminine curves. My cousin, Nick, complimenting my body while we lay there after he finishes inside me. Every night we went deeper into role playing. Some nights I would only be wearing a thong. He didn’t care if I wore a wig or any dresses available. He just wanted to fuck. I remember being so sore one day. It was a really good kind of sore. Like throughout the day a reminder of what we did and I would feel so turned on remembering him thrusting inside me.
