Ups, i was fucking my Gf’s best friend

Crazy shit like this happens when you don’t expect it at all. On the other hand you can’t force such a sex adventure to become reality. On that day we had some drinks and my gf’s best friend joined us for a night out.
When both girls became a little bit tipsy, they started kissing one another and touched their hot bods in a shameless way. I got so fuckin horny by looking at these sexy bitches rubbing their titties and muffs. I was shocked when my girlfriend removed her friend’s pants in our car and told me that i should fuck her. My brain told me not to do such a shit, but my dick left me no chance. My real girlfriend helped me to fuck her mate just in front of my parent’s garage and believe me or not, that kind of experience only made our love more big.
