KING-156 - If you endure, there's a prize! If you fail, immediate insertion of a large penis! College girl straddling with legs spread, performing a penis challenge! Peeling off sensitive pubic hair and licking vaginal secretions, twisting the tongue into the vaginal opening, and experiencing intense orgasm and ejaculation!! A raw, aroused female genitalia insertion ~Keiko Edition~

A high school girl is used as a practice tool for a novice male actor's penis. 1000,000 yen if you endure for 15 minutes! This challenger is Keiko, a member of the tennis club at a prestigious university. She is honest about her desires and actively participates in the project because her boyfriend doesn't perform oral sex on her. The challenge finally begins. Even so, the male actor firmly holds onto her beautiful buttocks as she instinctively tries to escape pleasure. He persistently licks from the hairless pubic area to the anus, and she responds with "Amazing... so embarrassing!" to his professional persistence even while submerged in semen and continuing to move his tongue. She is knocked out trembling with shame and pleasure. The penalty is immediate insertion and live penetration... She barely swallows the hard, large penis with explosive sensitivity, and then continues with piston-like thrusting and repeated penetration, remaining constantly aroused!
