You walk in on Emma sucking Ava's "cock"

This is the scene you walked in on. You had entered the house slowly. Emma's text had given you clear instructions: "Come home quickly. Enter quietly. Play dumb. Enjoy. U're welcome."

You had no idea what to expect when you did sneak in, and you never would have guessed this was what was waiting for you.

You quickly get a tent in your pants as you watch your girlfriend on her knees before your ex. You begin thinking about when Ava was yours to fuck. It's been too long since she took you in her mouth. You miss watching her struggle to take more of your length. You miss feeling your cock through her cheeks.

After watching the sexy scene for a couple minutes you loudly burst into the room demanding to know what was going on. You think you and Emma both put on a good show for Ava as Emma explained what was going on and you went from anger to acceptance. Finally Emma is begging you both to let Ava give her some pointers on a real cock - yours of course.
