I had never had sex with anyone else except my boyfriend until last weekend.

One of our friends who is dating my best friend, parents were going out of town for the weekend so we all arranged to spend the weekend at his place. Just the four of us nothing else.

Well the first night was pretty standard. Loud music, movies, hot sex with my boyfriend in our friends parents bed.

Well the next day was pretty much the same but we got into some alcohol and all chatted about who was better in bed, who gave better head. So we had a contest where my friend and I would each give our boyfriends head, first one to get them off we raced at giving our boyfriends head.

Well then it let to each of us having sex with our own boyfriend right there in the living room. Fucking us right there infront of each other. I'm not sure who started it but they were back on the topic of who was better in bed, and only the girls could judge so they decided to swap us. And while we lied saying they were about the same my friend told me afterwards that she thought my guy was bigger and better, I agreed but told her I didn't mind hers either as he lasted longer.

The rest of the weekend was pretty much like that.
