Having Laura serve as your own personal cocksleeve

You were curious about the limit of your power. If you did something physically impracticable, what would happen?

You grabbed Laura's legs, placing her on your erected cock like a personal cock sleeve. In the entire progress, Laura didn't do anything as if she didn't realize her feet were off the ground.

Laura's mother came to call her and noticed Laura standing still:

"What's wrong?"

"I... I don't know. My legs suddenly become numb, I can't move them!"

Unbeknown to her, it's untrue. She DID move her legs. They swayed helplessly in the air, making her moving up and down on your cock. Your eyes were glazed with pure lust at the place where your flesh connected, and your mind fixated entirely around the singular desire of fucking Laura senseless.

Floating up in the air, unable to move from the spot, she began to struggle anxiously. Laura's mother came over, grabbed Laura's arms, and pulled with all her might.

You could just stand there and let her try futilely, but after thinking you decided to step back.

"Are you fine?"

"Yes, I can walk again."

Having sex while walking backward was a strange yet interesting experience. Your movement made Laura bounce up and down on your cock like a rubber ball on hard ground. Your cock stayed motionless, but still thrusting into her tight cunt, swiveling around inside her, and repeatedly rammed into her cervix. Laura continued to talk like normal, but her moaning occasionally escaped from her lips, and her pussy became wetter and wetter.

Then a bulb light up in your mind. Laura's brain couldn't process your existence, but her body still realized something's off. When you placed her on your cock, her hands automatically gripped your shoulders like a fanny pack to maintain the balance.

What if I give her body a more permanent consequence?

An idea popped up in your mind. But you needed to test one thing first.

Instead of a short whistle, you made a long one. Suddenly, her legs passed through your hand, but your cock still stayed inside her.

It worked! I can turn some parts of myself intangible while others stayed tangible.

You continued to whistle while your hands extended into Laura's abdomen. In there you found a small cup made of silicone. Laura has chosen a cervical cap as her birth control method.

Slowly but steady, your left hand removed the cervical cap while your right hand stimulated her ovaries. Having to pay attention to many things at once, the pace of your jacking cock slowed down. You didn't mind it, since you didn't want to cream your load prematurely. However, Laura's body was aroused for a long time, now it's hungry for seed. Her drenched pussy squeezed all-around your thick dick, trying to milk till the last ounce of your cum.

Suddenly, you heard a "pop" sound. You couldn't answer how did you hear it, that sound should be below the audible range of human ears. Or maybe you just imagined that sound, because Laura's inner muscles suddenly pressed all over your cock and your instinct told you that your mating partner was ovulating. Anyway, you quickly pulled your hand back, hugging her tightly as the pressure began to go past the limit.

Then your mind exploded in bliss.

With a lust-filled groan, your cock erupted deep into her cunt. Violent spasms of your baby-making liquid splattered into Laura's unprotected womb, flooding everywhere. The sudden pleasure made her moan uncontrollably.

After blowing your last load into her, you quickly put the cervical cap back to its original place. The contraceptive tool now served a purpose opposite to its intended use: aiding the fertilization instead of preventing it. More ironically, the good quality of the cap backfired especially: not a single drop of semen could leak out.

You whispered into Laura's ears: "Happy birthday Laura! Enjoy my special gift."
