Give Ava a collar

You make Ava wear a choker at her work which she changes for a collar in the evening. Tonight you've led her on her hands and knees by a leash into your bedroom where you make her lap, like a dog or a cat, at your girlfriend's awaiting pussy with her tongue. When you mount her from behind, you call her a bitch and you push her head down hard against Emma's wet pussy. Your cock penetrates Ava deeply as you fuck her doggy-style.

Ava obediently gives eating Emma's pussy her all despite your **** from behind. "Eat her pussy, bitch," you tell Ava and she works her tongue harder. You slap Ava's ass hard, leaving a bright hand mark.
