Challenge him

"Dude. Just because you're impatient and can't salvage a nice pussy doesn't mean I can't fill teens up quickly." You say as you lift up the last girl and put your dick deep inside her womb as you start filling her up with a baby.

"Oh yeah? All I can see is a loser trying to justify his low sperm count" he says, trying to make you pissed at this point.

"You want a competition? You have it" you say in a snark tone as you're at the school entrance with the teen being filled to the brink at this point.

"That's exactly what I want bro. What do you suggest?" he says, rubbing his hands as you open the door to the school.

"Lets go to a classroom. The one who can fill up the most girls wins." you say as you put the baby battered teen on the floor and point to the closest classroom.

Jake starts running to the classroom and you're quick to follow, both making the floor sticky with cum. You can hear Jake scream "Sex time!" as he opens the door. While you're entering the room Jake is already pushing his cum blasted cock inside the teacher. "She counts for 2 right?" he says as he starts filling her womb.

"If you need it." you respond, more focused on taking the hottest girls on a baby making journey. There's about 20 people in the classroom, all girls. Without even looking her in the eye you pick up a cute brunette and lift her up on her desk. As you spray her insides with baby batter, massaging your balls to spray harder and more you hear Jake. "Done with the teacher. Bro I've won already."

You drop the thought of impregnating the hottest ones, they're all smoking hot anyway. You start going in a line, impregnating each girl by making their wombs filled to the brink with cum. Looking over to see how Jake is doing, he's ahead of you, which makes you push even further inside while squeezing your balls hard instead of fondling them. You look at the girls he's already impregnated, realizing their bellies, while large, are not as large as the usual ones. Could be that their wombs couldn't expand that much, they're teens after all, but Jake is most likely cheating a bit.
