My favorite M-type male sperm... I can't stop wanting it. A destructive riding position where I keep masturbating until I lose control of my bladder and ejaculate. Sato Nonoka MKMP-507

Just moments ago he was intensely masturbating, but at the moment of ejaculation, he abandoned his penis, letting it drip out in a "stopped orgasm," repeatedly giving him the pleasure of almost ejaculating. This is the kind of play where you most want to masturbate but can't, giving you absolutely no time to recover. Being perpetually fully erect, repeatedly forced to ejaculate and then abandon it, it's driving me crazy…
