I finally got my girlfriend and we had our first pure love sex! But... I still want to do it raw! ...But she won't let me do it raw! I hate the wall of only a few millimeters. When I was daydreaming about how good it would be to have raw sex someday, her sister showed off her big tits and tempted me by saying it was OK to cum inside her! I like her, but... if she invites me to do it raw, I can't refuse! I was so engrossed in her big tits and raw sex that I ended up cumming inside her! But after doing it so much, she finally found out! But it felt so good I couldn't stop thrusting! I cum inside her sister over and over again, even though she was right in front of me!
