The Semen Donation Truck!

A family father is walking down a dim lit street. It was supposed to be a quick pick-up gig for medicine but a halted truck on that street changes everything. Two succubus invite you to donate your semen using the condoms they provide. If you beat their record in the Whack-O-Mole minigame, they also gladly provide physical help in your endeavor at donating.
