Just a little practice session (NSFW) (full image attatched) (Patreon)

"Argh, sorry it's not like I could just ask for advice with this sorta thing."

This was a one off, spur of the moment commission for my friend Drale251art and their OC Lilith. You can find them here being friendly classmates, and I'm totally okay with that being canon. 

Still, you think you know someone and trust them completely to tie you up and they can still say something that totally surprises you :p
