I requested a dispatched personal trainer to tighten up my loose body. The person who came was... the hot teacher Erika with a super plump and round beautiful butt! She noticed that I was glued to her too lewd body and warned me, "Don't just stare at weird things, concentrate," but she showed me her beautiful butt and tempted me to do some muscle training, saying, "I'll give you a reward if you do it." I completely lost my reason as she let me touch her curves, climbed on top, and tempted me from a close distance...! Slutty sex with muscle training, oiled butt job ejaculation, vibrator masturbation, slutty cowgirl position... a full course of butt pressure for a total of 6 ejaculations! 130 minutes of being toyed with by the beautiful and big butt personal trainer Erika Ozaki intensifies her lewd muscle training.
