My husband's younger brother, who lives with me, can't control his sexual desire and attacks me while I'm sleeping...! I was surprised by the suddenness of it all, but my body, which was aroused by the lack of sex, responded obediently... I don't want to refuse... But adultery is risky and absolutely not okay... so I have sex while pretending to be asleep! If I make a sound, he'll find out what happened, so I try desperately to hold back my voice, but... it's leaking...! My body is trembling too...! A maximum sense of immorality in this sex session with no reaction allowed!!
