Keep going with two fingers.

Carl wondered if he could get her going with two fingers, and started pumping slowly all the way out, then all the way back in with his fingers. He added more lube to make it go that much easier.

Steffi's asshole stretched outwards as his fingers withdrew, pulling them back in. It was as if her asshole was asking his fingers not to leave. Carl was more than willing to oblige. Steffi's breathing became heavier.

"Ohh... ahh... this feels strange Carl I think it's enough..." Steffi whined.

Carl thought to himself how sexy this scene was, and then looked as his ring finger. Surely not?
