CESD-928 Shinkawa Aina: My Teacher Who Lost Her Virginity (Pet) ~Detaining My Beloved Senpai in a Lesbian Training~ Serebu No Tomo

A teacher named Mananagi at a private school is caught secretly masturbating in the restroom… and a female student witnesses the scene! From then on, the relationship between senpai and kouhai changes completely. Mananagi is blackmailed by her own student into undergoing lesbian training. At times, she's tied up and forced to orgasm violently; at other times, she's made to march nervously in tight full-body suits. Later, she's subjected to humiliating panty peeping and penis pumping. 'You're totally mine now, senpai…' '…Yes…' The two cover their entire bodies in oil and passionately embrace with their large breasts pressed tightly together.
