I just had Feb. Vacation and one day it was about 11 in the morning and I texted this girl who is my friend with benefits. My parents were at work for the day so I told her she could come over if she wanted. She replied and said sure but she was with her best friend who she was always with so they both came over. We hung out for a bit and I dont know how we got into it but they both agreed to make out in front of me. Her best friend is my boys girlfriend so we had seen them makeout before. I got them to take there shirts off and then the friend said she wanted to see me and my girl fuck. My girl gave me head and a titjob while her friend sat there and watched me cum on her boobs. It was a very big turn on to have another person (especially another female) watching me receive oral sex.
