When your best friend and roomate starts dating your own brother things like this might append. Since me and Lina live together we like to have group sex with our boyfriends and we exchange partners what I didn't expect was that after she met my brother a few months ago they would start dating, for her the idea of having me fucking my own brother was a really turn on, I was the only one who had think about for awhile but also my curiosity and my friend's pressure made me do it and... yeepp I loved it!
