My lewd lower body, Tachibana Serina, can't move, but still gets a full erection

Make the big-dick shemale Tachibana Serina prey to confinement! Serina is restrained under an absolute master-servant relationship and is awakened to her true nature as an M. The more you are tortured, the more lewd her body reacts! Her huge penis is erect and she gets an upright erection and gives a huge milk squirt! Her twitching body is in a daze! The feeling of making a superb M girl a pet is the best!!
