NHDTB-542 Every night, I secretly applied an aphrodisiac to my sleeping sister's nipples. As a result, she became so sensitive that even the slightest rubbing of her clothes would make her climax.

Day and night, my brother sets up an aphrodisiac trap! In the middle of the night, he lifts his sister's futon, removes her pajamas, and rubs plenty on her nipples!! While she sleeps, it slowly penetrates through her super-sensitive mammary glands! Before she knows it, her body becomes more sensitive! Just a little stimulation makes her wet down there and have a nipple orgasm! Eventually, she goes wild with forbidden penetration, indulging in incestuous sex!!
