"Hurry up little kronie, don't you wanna make me a mother?"
You're pumping as hard and fast as you can

Every nerve in your body commands you to impregnate her
Even so you just know she'll disappear at the last second
"5"
She starts counting down in a smug
"4"
You pick up the pace
"Unf, 3~~"
Even she can't help but let out some signs of how much pleasure she's feeling from your thrusts

You just see your seed pathetically splatter all over your sheets, ruining your covers yet again
Humiliation washes over you yet again
"Oooh, so close~"
You look over and see her triumphantly looking down on you like pic related
