In this erotic ASMR video, you partake in a second medical study comparing erect penis size and amount of ejaculation/sperm count. I admire your cock as I measure and inspect your penis. There is plenty of sexual tension as I can't help but enjoy watching you masturbate; your penis is my favorite out of all the subjects. I can barely contain myself as you ejaculate so much cum for the medical study. (Video ID: ASMR30)
