30-year-old Yuka Imaizumi. A housewife married for five years, she lives with her company employee husband and their son who attends kindergarten. When it comes to sex, she says, "The intense moments right before ejaculation feel the best." She explains that creampie makes the pleasure even greater, adding, "With creampie, I love continuing to thrust my hips hard even after I climax, until all the sperm spills out." She feels a completely different sensation when condoms are used. While masturbating to AVs on her smartphone, she's always been struck by how intense the male performers' hip movements are, and couldn't suppress her curiosity—wondering, "Is that what simultaneous orgasm is like?"—prompting her to join this shoot. Tonight, she'll experience piston movements beyond her expectations. Stay tuned!
