[Slice of life]

What would you do if you could copy abilities during an apocalypse?

Of course, you can only copy women's abilities by having sex with them and absorbing their coitus essence!

Jake Mystro, a determined and strong-willed teenager without an ability, was frowned upon and disdained for being powerless, as his body even rejected artificial abilities. Yet, that didn't bother Jake or make him sad, rather, he supported himself with the help of beast gears to avoid being bullied.

However, on a particular day, Jake got tricked into awakening his Vampiric powers, but the process left him in a life and death condition. Luckily, he acquired the 'Cuckold System.
