Substitute Flesh Toilet - A 10-Day Captivity Life with an Insatiable Yakuza Man, Impregnating Me - Akari Tsumugi

She's a fine woman... I can't get enough... If you want to save your little brother, become my woman for 10 days! An older sister imprisoned in the home of a virile yakuza as collateral for her beloved brother's debt, forced into physical servitude. Whenever I feel like it, stick your ass out! Got it? Anytime, anywhere, if a man wants to cum inside, it's immediate insertion right there! Immediate ejaculation into the womb! Days filled with pleasure and covered in semen... With a body so lewd... My cock just won't calm down! A body that grows more obscene each time the cock is thrust in.
