A thing that happens when you have an erect penis. They can be small or fucking huge. When I say huge I mean 15 gallons of hot juicy semen. Enough to fill up a bathtub.
Holy shit! That was a mega cumsplosion!, ugh, no don- *gasps for air*, dont pull out, I like your sweet sticky hot juicy spicy tangy cum.
