SW-226 I was having sex with my girlfriend's friend and she found out, and I thought it would turn into a hellish scene, but it turned into a heavenly threesome! It felt so good!

Her friend came over while she was out. Hearing her worries, I got horny and wanted to have sex, but then she came home and it looked like it was going to be a bloodbath, but she peeked in and got excited, so we all ended up having sex. I saw her having sex with her friend without her knowing, and her friend asked me to have sex with her too, so we all had sex.
