To say I had a little bit of a crush on my younger cousin Corinne would be a bit of an understatement. Her brother Mike and I were close growing up and I stayed the night at their house quite a bit. One summer during high school, I was staying with them for a few days and Mike had to work. Corinne invited me to swim with her over at the neighbor's pool. Before that day, I really never saw Corinne as anything other than Mike's younger, and mostly annoying sister. Seeing her in a bikini that day completely changed how I saw her. Nothing inappropriate happened, I just couldn't take my eyes off of her while she tanned on the lounger.
Shortly after that day at the pool I graduated high school. I went into the Army and only saw Corinne and Mike when I was home for Christmas. I typically took my leave around that time of year so I could see more of my family. We would gather together with all of my aunts, uncles, and other cousins for a big meal and exchange gifts. After the big family get-together, the cousins would usually join up at Mike and Corinne's house. Their parents were pretty laid back and let us drink as long as no one drove home. There would usually be around twenty of us when you added some of the cousin's dates.
I was on my third year in the Army and heading home once again for Christmas. Corinne had just turned eighteen earlier in the month and wanted to celebrate again with everyone at the cousin's after party. We all had a great time and drank way more than we should. One of my other cousins, Holly, was drinking away the boyfriend that just dumped her. The highlight of the evening was when she forgot she was with family, and flashed her perky tits at everyone shouting; "I guess that ass-hole doesn't get to suck on these anymore!" I wish I had my camera out for that one.
Corinne quickly helped Holly get her shirt back on. I couldn't voice my disappointment since she was my cousin, but I did enjoy seeing Holly's cute little breasts. After all of that excitement, things died down a bit and everyone started crashing around the house. Mike had bunk beds in his room, which is where I normally slept. I went to use the bathroom outside Mike's room, but apparently Holly was in there with the door locked paying for all that she drank.
Corinne had her own bathroom off of her bedroom and offered it to me. While I brushed my teeth, I couldn't help but notice a lace bra with floral print and some skimpy matching panties in a pile over on the floor. It immediately made me think of that day I saw her in the bikini. I started to imagine what she looked like now, wearing only the bra and panties. She had matured a little more over the past few years and was quite beautiful. I could see here there with her firm breasts pushing against the lacy bra, her long brown hair in a loose braid draping over her shoulder. I imagined her looking at me seductively as she bit the edge of her lip and slid her hand down her firm stomach and inside the lacy band of her panties.
I picked up the bra out of curiosity and saw that she wore a 36C. As I held it with one hand I slowly started rubbing my growing erection through by boxer briefs. I then looked down at the panties. I pulled down the front of my boxers releasing my now fully erect cock. I dropped the bra and picked up the panties. I saw that they were a thong, wrapped them around my cock and slowly started to get myself off.
Suddenly there was a loud knock on the bathroom door. "What are you doing in there?" Corinne asked.
"Just a second," I said startled as I tried to compose myself.
I quickly dropped the panties while simultaneously pulling up my boxers. I turned to open the door announcing that I had just finished brushing my teeth. I had quite a bit to drink and wasn't sure if I had been making any noises while she was just outside the door. I also wasn't sure how long she had been listening. My plan was to quickly squeeze past her and keep her from seeing my aching cock pressing out against my boxer briefs.
I opened the door and was caught like a deer in the headlights, as I stared at her braless breasts pressing against the thin fabric of her low cut, spaghetti strapped, sleep shirt. Her nipples were clearly visible poking at the fabric just below the lace trim. I would like to think the lack of control over my eyes was due to the alcohol. They betrayed me as they moved further down to her partially exposed midriff and her low cut, matching lace pajama bottoms. My cousin sure liked lace. My eyes were locked right on her crotch and I thought about how I was just jerking off with her panties. With the alcohol, I wasn't quite sure how long I had been staring.
"Hello!" Corinne interrupted. "What are you gawking at?"
I immediately looked up and saw the confused look on her face.
I didn't get a chance to respond before she looked down towards my crotch and asked, "What is that?"
I stepped back a bit as she immediately reached out towards my cock.
"Why are my panties hanging out of your boxers?" she asked as she snatched them away. I then noticed her eyes widen as she realized I had a massive erection pushing out against the front of my boxers.
"Uh, oh, um... Those are yours?" I mumbled as I quickly pushed past her. I didn't say another word as she just stood there trying to figure out what just happened. I went into Mike's room and closed the door.
I sobered up quickly as I lay in bed staring at the ceiling thinking about what had just transpired. I wasn't quite sure how I was going to face Corinne in the morning. I decided I would just try and sneak out of the house early before anyone else was up and never mention the encounter. Hopefully, she was drunk enough she would question it even taking place. If she said something, I would play it off as though I didn't even know it happened.
After the shock of getting caught wore off, I started thinking about how incredible Corinne looked in her skimpy pajamas. I wanted to finish what I started in the bathroom, but my cousin Mike was sleeping down below. I tried to put the picture of Corinne out of my head, and finally fell asleep.
I woke up about an hour later with a need to pee that I couldn't ignore. I grabbed my phone and used the flashlight on it to make my way down the dark hall only to find the bathroom door still locked. The light was on and I could hear someone lightly snoring. I knocked softly trying to wake whomever was in there. Not being able to hold it, I went to my aunt and uncles room. It was locked and I could hear my cousin Evan in there with his girlfriend. The house had an alarm on it, so I didn't want to risk going outside and setting it off. This only left one option: see if Corinne's room was unlocked and sneak into her bathroom.
I walked down the hall towards her door and was relieved to see it was slightly open. I peeked in to see her lying in bed fast asleep with a good amount of light coming in from her bathroom. I turned off the light on my phone before entering. As I slowly pushed open the door enough to squeeze in, I looked and realized her pajama top had shifted while she slept and her breasts were now mostly exposed. She had, what in my opinion where, the perfect breasts. Her areolas were a bit bigger than the size of a quarter with nipples that I wanted to wrap my lips around. I stopped and took in the amazing view, keeping an eye on her perfect face to make sure she wasn't going to wake up. My eyes traveled down and were disappointed to see only one leg hanging out of the sheet that covered her lower half.
