...incest...

MNGS-077 "I've been waiting for your return," said the father-in-law I hated so much when we finally reunited. He had turned into a stinky old man living in a garbage-filled room... He relentlessly r***ing me with his pent-up, abnormal sexual desire, cumming inside me repeatedly. He held me captive as his wife until I got pregnant as part of our family plan. Misono Waka​

LULU-454 I couldn't resist the unconsciously inappropriate, provocative big butt of my niece, a J-type girl in mourning clothes, whom I reunited with at a memorial service. I gave her a blissful, squirting orgasm with incestuous thrusting, bringing a smile to her face. - Karin Kitaoka​

WAAA-698 My wife's stepdaughter (in her rebellious phase) is always defenseless and goes braless, her breasts peeking out. I couldn't resist her fair skin and pink nipples, so I played with them, taught her how to orgasm from nipple stimulation, and had sex with her... Yukimura Izuki​
