"Allow me to help." (Smut)

I got bored so I wrote this :V

Also, this is a Rimuru x Luminous smut if you couldn't tell.

Alternate Title: Luminous tries to masturbate but fails as she realizes she's a spiritual being. Buttttttt, Rimuru saves the day like the smartass he is! It's just that this time... Things need to get a little more practical... Physically...
