2boysn1girl
The girl was dating the slim guy and was slowly corrupted. She ended up having sex with the other guy. According to one of the comments from a video: "The guys' username on Chaturb4te is 2boysn1girl. Up until two years ago, they have streamed on 42 different days, with 9 different women. This shy beauty was the less muscular guy's girlfriend. This was their first day streaming with her, 14.09. On 07.09 she kisses him. On 09.09 she has sex with her boyfriend. On 12.09 she finally has sex with his best friend, with her boyfriend's consent. Then they become very comfortable, but there are just blowjobs...on camera."
However, I have found videos of them that looked like there was penetration.
Unfortunately, I don't have the videos, so if anyone can find, please share.
