This happened a couple of years ago, a week after I became legal. I had developed early and had absolutely massive breasts for my age. I spent most of my life trying to hide them at this point, ashamed I was so different.
One night my brother's friend had come round, but I was the only one in. Mike, my brother, had gone out but I told him he would come back soon, and was welcome to wait.
He accepted, and came in. As I hadn't been planning on seeing anyone I was wearing a cropped T-shirt my breasts were virtually falling out of, and no bra. My denim shorts showed off my slim legs nicely, although they were too short for me to even think about wearing in public.
I saw Greg staring at my breasts, and I reddened. I turned away from him, asking if he wanted a cold drink while he waited. He said yes, and as I reached up to get the glasses from the high shelf, the bottom of my tits became visible, and before I knew what was happening, Greg was standing behind me, his hands slowly working their way up my stomach.
I froze. His hands cupped my breasts, and I heard him groan in my ear.
'My god Mae, you're amazing,' he said, 'why don't you always dress like this?' He was rubbing my nipples, and they had become like rocks.
I let out a small moan, and didn't say anything as he pulled my T-shirt over my head. My breasts sprang free and I saw my top fall to my feet.
I felt a thrill as he turned me around, I had never been so exposed before, I was loving it. He roughly lifted me onto the kitchen surface and pushed me back against the wall. He took one of my breasts in his mouth, and began sucking and biting. I opened my eyes and looked up realising that I was sat opposite the very large window in the front of the house, which looked out onto a busy street. It was usually covered with curtains, but they were being washed so I soon realised I was totally exposed.
I knew people would be watching me, and they were. A group had stopped, and were enjoying the show, but not as much as I was. I couldn't believe all this people were getting turned on by watching me, I had noticed a few men rubbing their crotches.
I was torn away from my pleasure as I heard a loud zip, Greg had undone his zipper and was busy releasing his cock. I had never seen one before, not even in pictures, and as it sprang out, all hard and purple, I began to feel sick. When he roughly pulled me off the counter, I could tell he wanted me to blow him. I panicked, realised what I was doing. It was like waking up from a dream, all of a sudden I felt exposed, vulnerable. I stood and ran out of the room. I think I heard him shouting after me, but I quickly ran up the stairs and locked myself in my room.
The next day we were eating tea as a family downstairs. My parents announced that they were going away for the weekend. They were leaving Mike in charge, with strict instructions to not have parties.
I knew he would have a party, and Greg would come.
I had been thinking about the day before a lot. In fact every time I did I got really wet, and soon realised that I was incredibly turned on, not from Greg, but from all those people outside seeing me. I tried to stop feeling this way, but part of me just wanted to do it again.
But as I knew there would be a party my heart sank, I didn't want it to happen again, especially not with Greg.
