HMN-620 My girlfriend's sister loved me so much that she secretly made a baby with me and squeezed out 10 loads of sperm. Suzunoie Rin

Suzunoie Rin! Honnaka's Dengeki Exclusive Decision!! The first renewal of that popular series! My girlfriend's younger sister missed the last train, so she came to stay at the house where my girlfriend and I live together! She's petite, but her thighs peeking out from under her skirt are sexy, and I'm also curious about the swell of her breasts...I don't know if she noticed my gaze or not, but my girlfriend's younger sister's temptation is crazy! "Did you know? Just a blowjob isn't cheating, you know?" Even though my girlfriend is right next to me, she shows me her blowjob and pussy and tempts me with cunnilingus. "It's not cheating if I cum inside!" she says, straddling me raw!! I'm embarrassed as she keeps seducing me...!
