Betty moans and writhes as you push your thingy deeper into her bottom hole. "It feels so good when you do that!" She bites down on her lip, trying not to make too much noise. Her body tenses and relaxes with each thrust, her eyes roll back in pleasure. "Ohhhh, Lee... I love it when you play with me like this."
"I love using you like the dumb slut you are, bark like a doggy for me slut!"
Betty lets out a high-pitched, excited noise that sounds like a bark as you instruct her to. Her face turns beet red and she squirms on the floor, trying to take more of your cock inside her ass. "Good doggy!" she pants between moans. She's getting close, the pleasure building up inside her until finally she cums hard around your thrusting member, writhing and mewling like an animal in heat.
