When Wi-Fi-addicted Aika loses her connection, she moves into her male friend's room and refuses to leave. She offers unlimited access to her huge, soft tits in exchange for his Wi-Fi, even letting him use them for a titjob, but her complete lack of reaction leaves him frustrated. He secretly coats her breasts with an aphrodisiac; soon her nipples and tits become sensitive, her panties soak through, and she tries to hide how hard she is cumming during penetration. Once her home connection is fixed, the deal seems over—but Aika returns, this time not for the Wi-Fi but for his cock and more sex.
