[Yuuki Saien] Shojo ja Nai kara!

A bold, big-breasted beauty declares she's not a virgin and begs a small group of eager men to put her claims to the test. Teased for how sensitively her breasts respond and how well she's developed on her own, she is coaxed into a thorough, hands-on rehearsal that quickly becomes an overwhelming first experience of real sex. Flushed, sweat-slick and eager to please as the men praise her as a hard worker and urge her to let them finish inside, she surrenders completely to the relentless, creampie-filled lesson.
