Mizuki-chan (nickname: Yurufuwa Manko-chan), our regular sex partner who we always rely on for 'that'. Today is her birthday☆, so we held a surprise birthday orgy party with Mizuki-chan's other sex partners. From fellatio in the car while traveling to full-blown eroticism. At the hotel, Mizuki-chan and we all cum like crazy with a chaotic dick and pussy frenzy. Mizuki-chan still isn't satisfied. More and more! She overwhelms us until morning with her outrageous libido (sweat).
