He does and then breeds you!

Principal Williams grinned behind you as he ramped up his speed, making you wail as your pussy was being resized by the thickest cock you'd ever had. You moan as you feel your D-cup tits smacking back and forth, the sweat flying off them as they hit your torso. You silently thank God you put your hair up in a ponytail because it would be sticking to you right now. You whimper as Principal Williams reached down and started flicking your bean, making you go even more cross-eyed as you came again, making you even more tired.

Principal Williams stops, wraps his arms around your waist and pulls you backwards with him on the bed, getting you in the reverse cowgirl position, you looked back at him and moaned as he lifted you up and down, only stopping when you squirted again, your cum splattering the bedsheets.

"Mmm, spin around for me Joy..."

"Y-Yess Daddy...."

Exhausted, you spin around, you came again as your pussy clamped down on Principal Williams cock, before you slumped, on the verge of passing out on his chest. You didn't see the big grin on his face as he started hammering his cock into your soaked pussy, making you let out a scream as you squirted again, this one a much weaker one than the others had been, but it did take away your last bit of energy, you let out a tired whimper as you collapsed on Principal Williams.

What you had forgotten due to being **** was that you were already at peak fertility today anyway, so Principal Williams fertility booster that he dosed you with just ensured that when he came inside of you, your eggs were going to be easily conquered by his potent seed, you see, when Principal Williams was creating the **** he used on you, he also created a **** that would permanently increase his potency by 1000%, so even his pre-cum was potent.

Knowing that you were passed out, Principal Williams didn't hold back any longer, he slammed you down hard on his cock and moaned out his release, his hot, sticky, potent cum fired into your young womb, rope after rope flooding your cervical chamber, with Principal Williams thickness, none of that cum came back out, ensuring your insemination at your former Principal's hands (and cock).
