OMG after watching all that cum exploding I couldn't stop it and didn't want to, I cum like a grunting, snorting, fucking prize bull and it felt so glorious and lustful.
Sometimes when I wake up with a full erection, I'll do what Dad at the 2:48 mark (blue pajamas) does, get up and fully masturbate onto something, or into the bathroom sink, wipe my penis then go back to sleep.
