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.
