Domination/think of a way to hurt her
From Create Your Own Story
You look at at Diana's legs resting on your shoulders and you get an idea. You begin pushing them back towards her, slowly inching her feet towards her face.
Diana eyes open as she realizes what you're doing. "Actually," she says, "I'm- I'm not really that flexible."
"Oh," you remark, not really surprised, "that'll just make this more fun."
"Uh, wha-" Before she can finish, you roughly shove her ankles behind her head.
Diana lets out a bloodcurdling scream as her legs stretch far beyond what her out of shape body can bear. Hearing her shriek so loudly into your ears almost makes you regret doing it, but you're not going to let that stop you from doing your job. You now have easier access to that sweet, MILF pussy, so while she howls, you resume your pounding.
You hold Diana's ankles in place while you callously fuck her over the sounds of her wailing. After a few minutes, her screams lessen to sobbing, and then to a light whimper. "Told you it would be fun," you say to her, eliciting another sob.
You begin to feel that tell-tale tingle in your balls, so you prepare to blow your load.
Where are you going to cum?
