[Reducing Mosaic]MIAA-550 A former classmate who used to bully me, a black gal, unexpectedly became my sister-in-law! Unable to satisfy her husband, she tortures my pathetic nipples. Ranka

Huh? You don't mean... because of moving troubles, my brother is taking refuge with his wife... and it's Ranka-chan who bullied me in school?! Bitter memories resurface. I thought I'd avoid her as much as possible until we leave, but starting from not telling my brother, I'm gradually being bullied again as an outlet for her excessive sex drive! She pinches my nipples at every opportunity, bites them, steps on them with her feet... even my dick is tormented freely, and it's frustrating yet I feel it～!
