Stay deep inside her, keep driving your cock against her cervix

You decide to keep trying what seemed to work the first time, and continue to attack her sensitive cervix with your long cock. Most of the women you've been with don't enjoy this most of the time, but when highly aroused, it can make them cum from deep in their core, and those have been some of the hardest orgasms you've ever witnessed.

You lock your hips with Kavita and mash your cock against the back of her pussy, trying to stimulate her cervix again, hoping you've found a weakness.

Kavita raises her upper lip, her face a mix of discomfort and desire, pulls her legs against her restraints, and tries to lock you deep inside.

"Oh, you think you've discovered a crack in my armor have you? I came because I made myself cum, if you keep jamming that log into me like that, I'll break it off." she says.

With that she squeezes your cock tightly and twists her hips, jerking your body to there right and wrenching your cock inside her painfully. She has surprising strength and control of her kegels, which right now feels a bit scary.

"Ok...sorry..." you say between breaths. "I'll take it easy."
