I requested a temporary personal trainer to tighten my loose body. The person who came there was... the cool teacher 'Erika' with a super plump and beautiful ass! Noticing that I was glued to her naughty body, she warned me, ``Don't just look at the strange parts and concentrate,'' but she said, ``If you can do it, I'll reward you,'' and showed off her beautiful ass and tempted me to do some muscle training... and touched my waist. My rationality completely collapses due to the temptation of being on top of me, riding on top of me, and getting close...! Muscle training slut torture SEX, oil butt job firing, vibrator masturbation, slut torture cowgirl position... 6 shots in total for full course of butt pressure! 130 minutes of being toyed with by a beautiful personal trainer 'Erika Ozaki' with a big ass and a lewd muscle training exercise.
