When I was a kid I spent a summer with my sister. I wss 13 and a virgin. She lived with her roommate from high school. They were both 19 and had been best friends since they were 12. She had known me for years and it was nothing for us to share a bed together. My sister even insisted I sleep in her bed some nights since they had no spare bed and the couch was small.

My sister let me do pretty much what ever I wanted. She let me drink and smoke weed with them all the time. One night we were all drinking watching movies. My sister and her roommate were very drunk. My sister tells us she's about to fall asleep, so we tell her were going to her roommates room to watch it.

We go to her room and I put the movie in and go lay by her. We're watching the movie and talking. A sex scene comes on the screen and we both get quiet and watch. After its over she says she bet that felt good. So curiously I ask if she's ever had sex before. She says yes and tells me about her first time.

The story made my dick hard. She asks me what I've done with girls. I tell her I've only kissed girls before. She asks if I've ever let a girl touch my dick. I tell her no. She asks me if she can touch it. I tell her yes. She reaches into my shorts and grabs my dick and strokes it. She asks me if it feels good. I say yes. She whispers in my ear if I ever had my dick sucked. I tell her no. She pulls my shorts off and slowly kissed my dick. She sucks it til I cum in her mouth.

We're laying together waiting for me to get hard again. I ask her to suck it some more and she does. I cum in her mouth again. She then grabs my hand and makes me finger her. When I get hard again I get on top of her and fuck her. She told me not to cum in her but I couldn't help it.

Afterwards we both fell asleep. She gave me a blow job one more time in the morning. That was our first sexual experience together. We were left alone quite often that summer. Fist of many.
