This was earlier this morning. I'm not sure where else to put it, but I need to talk about it.
So I had a friend stay the night, and to cut a long tale short, we ended up naked in my bed messing around. We literally just fingered each other and toyed with each other's boobs.
My brother happened to come in on us as my friend and I were joking about fucking. They've had sex in the past. I knew they wouldn't be able to leave with our parents around, so I pulled my cover over my head and told them to hurry. I ended up covering up my friend. We scrambled around, trying to untangle ourselves, when I felt him get on the bed, followed by his dick pressing against my pussy and sliding in.
All I could do was moan as he went fast and hard. My friend glanced at me with wide eyes and told him he was with the wrong girl. She threw the blanket away from us so he could see, and when I came, he glanced at me. I'm not sure why, but he started cumming as well.
He just discharged a few shots into me before pulling his dick and dropping the rest in my ass. Because it was an accident, we all agreed not to say anything. I watched the two of them fuck a few minutes later, and it was pretty hot.
I keep thinking about it, and I'm not sure why it excites me so much.
