DVAJ-641 - [29th day of abstinence...] I promised to have the best sex ever after refraining from masturbation for a month, but I succumbed to my girlfriend's younger sister's temptation to reverse NTR and couldn't stop having raw sex even after I used up a whole box of condoms and ended up creampied over and over again.Mito Wakui

My girlfriend read an article that said, ``Sex feels great after a month of abstinence!'' and was forced to refrain from masturbation, but from that day on, her younger sister Mito began seducing me. It seems like she's interested in me, and normally she's just flirting with me, but she's so horny from her abstinence that I can't take my eyes off her panty shots. No, no, I don't have a girlfriend... But when I'm about to end my abstinence in one day, I say, ``If you put on a condom, it's not cheating♪'' I lose my rationality at this very convenient invitation, and I fuck her J-type body until I use up all the boxes! However, her pent-up sexual desire cannot be stopped and she enters into forbidden raw sex!
