[Motsuaki] My Younger Brother's Lustful Friend is So Annoying! [MTL] [Full Color]

An busty older sister's patience is pushed to the limit when her little brother's small, endlessly horny friend comes to stay the night and treats her huge, soft breasts like his personal toys. Annoyed scolding on the couch and a forced shared bath quickly give way to relentless paizuri, deepthroating blowjobs and rough, creampie-driven pounding that leaves her flushed, sweating and helplessly aroused despite her protests. The brat's shameless stamina and huge appetite only grow more demanding, dragging their teasing cohabitation toward a sticky, impregnating happy ending she can't quite resist.
