Small-breasted wife Hitomi Morimoto secretly meets her lover between work appointments. While she is orgasming under double-hole toy teasing, her husband suddenly calls. Her lover enjoys the danger and keeps working the toys despite her protests, forcing her to struggle through the conversation without being exposed. She survives the first call, but her husband rings again in the middle of screaming anal sex, leaving her writhing and climaxing beside the phone while trying not to give away the affair.
