"I've had clitoral orgasms, but I've never had a vaginal orgasm." Ms. Momoka Anno, 42, lives in Itabashi Ward. She's been married for 18 years and is the mother of two children. She usually works as a telephone operator for a mail-order company, but she loves naughty things so much that she enjoys prank calls from perverted customers. "I get excited when I have dirty conversations in secret so that no one will notice... I get wet as I imagine the invisible person." Momoka, who is such a slutty woman, still has sex with her husband twice a week, but... "It feels like we're just doing it. I'm dissatisfied because I've never had an orgasm during sex, even though I can orgasm during foreplay." She even had an affair with a coworker in order to experience a vaginal orgasm. Today, she's motivated to try some slut play that she doesn't usually do, but will she be able to have the best vaginal orgasm sex that her brain can feel!?
