You Have No Idea How Many Times Your Brother Has Inserted Himself Into Me While Pretending To Be Asleep, Do You? MIRU.

My husband's younger brother, who lives with us, can't control his sexual desires and attacks me while I'm asleep! I was startled by the suddenness, but my body, frustrated from a sexless marriage, honestly reacted... I don't want to refuse... But cheating is risky and absolutely not allowed, so... I'll have sex while pretending to be asleep! If I make a sound, he'll know I'm awake, so I desperately hold back my voice, but... it slips out...! My body also twitches...! A sex act with maximum sense of taboo, with reactions forbidden!!
