Hitomi Tammura enters a standing-doggy challenge with one simple rule: make the man ejaculate within five minutes of penetration to win. Atmosphere matters, so she licks his nipples, caresses him carefully, reaches for his cock, kisses him, surrenders dreamily, wets her pussy with fingering, and makes him rock hard through oral. Then he enters from behind and the challenge begins. Can uniquely charming, adorable Hitomi complete the mission?
