RCT-604 An Helicopter Mom Controls Her Son's Ejaculations

My son's ejaculation management was worked on by my mom to improve my grades for the exam! Until the day of the test, the mom puts a sticker on the calendar with a hand job and a blowjob and thoroughly manages one shot a day. A reward blowjob from a young and cute tutor... Punishment with a chastity belt as punishment for ejaculation other than mom! Gradually, my mother also asked for it, and I couldn't stand it, and it developed into incest.
