My girlfriend never lets me have sex with her raw... I wonder if she'll let me have sex with her raw to celebrate my complete recovery from my broken bone? I had such a faint hope, but she said no! While I was resenting the 0.0mm wall and fantasizing about the pleasure of raw sex and getting my crotch pumping, her older sister showed off her big tits and seduced me by saying it was OK to cum inside her! I like her, but... I can't resist being seduced by such an attractive older sister! I was so engrossed in her beautiful big tits and raw sex that I ended up cumming inside her repeatedly! My girlfriend eventually found out, but it felt so good I couldn't stop thrusting! ~Special Thanks Konatsu Kashiwagi(younger sister role)
