I Won't Lose to an App! -Foursome Arc-

Be careful about making apps that can manipulate people, or you might get manipulated yourself... into having a foursome with three hot women. On his quest to stop people from using his app for evil, Jake only has one loose end to tie up: Yuuki Mizuno. But she may have some plans of her own to get back at the man who stole her pregnancy counselor from her. Plans like turning him in to her own private flesh vibrator!
