Painful Endeavour

She slowly opened her eyes, she had light blue eyes, and as she opened her eyes, the man left her breast, from his hand, she smiled a little while kept moaning softly and jumping on him, trying to get his dick as much inside as possible. She holds both of his hands with her hands and puts them on her breast.

The man hesitates for a moment, but she starts pressing her breast with his hand, and the man feels encouraged and starts pressing them. She started moaning loudly and even jumping rapidly, it seemed like she was about to reach her goal. Her speed and voice kept increasing, while after a point it got hard for a man to keep up with her. 

As she was jumping rapidly it was getting painful for him, so he slowly stopped responding out of pain, but she kept doing it anyway. And at some point, he starts screaming and begging her to get off him, but she doesn't care. She took one more push and, "crunched.., cracked" his bones got crushed by her hips.
