My girlfriend and I moved to Colorado with another couple we were friends with. We moved I to a three bedroom three bathroom house, me and my gf took thr master and they took the other two rooms one for my roommate to produce music in and the other for them to sleep. I started flirting with his gf when the two of us were alone and one night while my gf was working her bf was upstairs producing, she was in the kitchen making Chilli I saw her taste and asked if I could have a taste she said sure and that's when I leaned over kissed her. Soon we were making out, I bent her over the counter and ate her pussy from the back before fucking her doggy of thr kitchen floor, I creampied hee, then she sucked my cock. 15 minutes later I was playing fortnite on the couch and my gf gets home from work. Two days later roommate and his gf are sleeping in separate rooms.
