Lie still and quiet, continuing to let her lead
From Create Your Own Story
You like the way this is going. You hold still and let her continue to stroke your shaft. You switch back and forth between her nipples, suckling gently.
Her free hand works between her legs. She speeds up her stroking. You shudder at her touch.
"You're ready," she purrs. She removes her hand from your quivering pole and slides her dripping box onto it. She lifts her body upwards and presses down on your chest with her hands as she slides up and down.
"Oh my..." you whisper.
"Enjoy," she giggles. "I had a hysterectomy several years ago, so I can't get pregnant. I want you to fill me up."
I don't really have a choice, you think. You are bound to the bed after all.
She climaxes once, then again, and you feel your balls tighten and your pole twitch.
"I'm..."
You don't finish your sentence, as you erupt into her. She locks her legs around you until every drop of cum is extracted from your cock and balls, then climbs off you and lies next to your bound body.
"Very good," she purrs. You both rest for a moment, regaining your higher brain functions.
