My husband's brother, who lives with us, can't control his lust and attacks me while I'm sleeping! I'm startled by the suddenness of it, but my sex-starved body reacts honestly... I don't want to refuse... But adultery is risky and absolutely forbidden... So I end up having sex while pretending to be asleep! I have to desperately hold back my moans because if I make a sound, I'll be caught... But I can't help it... My body trembles uncontrollably... Forbidden reaction, maximum guilt sex!!
