Life as a couple (Patreon)

When you're young (and perpetually horny) and you host under your roof a stunning alien girl who is intended to become your wife in the next future, sooner or later something lewd will happen.
Ataru, after Lum's umpteenth request to do something as a couple, shows to the alien girl the best way a couple is supposed to spend its time.

Based on "Urusei Yatsura" anime show.
