Visit the bathroom first

by President paradox, from writing.com

You walk into the boy's bathroom and rush trying to make sure that the gallons of girl cum in your belly doesn't make too much noise and catch the attention of anyone inside.

You pull down your pants and turn back to the toilet, you squat down just a little in preparation for flood of seed that's about to rush out of your bubbly ass. You reach back and try tugging on the buttplug only to come to the realization that it's so much bigger than first thought, pulling just a little harder you feel a spike of pressure laced with pain.

(Oh fuck this is going to be so much worse than I thought.) As you grabbed the buttplug with both hands this time and giving a harder pull you let out a girlish scream as the buttplug finally escapes the confines of your now gaping asshole.

You let out small squeals as the principal's thick warm baby batter rushes out of your ass, after a minute or two, and several tiny cum shots, the flood finally comes to a stop. You plop your phat ass on the now sticky toilet seat and look in the toilet bow, it's almost filled to brim with fertile girl cum.

Your about to pass out from the exertion of draining your asshole when you hear the bathroom door slam open and booted feet stomp into the bathroom.

"Please don't do this I have a girlfriend, she'll punish me again if I come home with another woman's load in my pussy!" A masculine voice whimpers out as you hear rustling of clothes being removed.

In reply you hear a loud smack. "Shut the fuck up cumdump! You shouldn't have come to school in these ass hugging jeans if you weren't looking for some big girl cocks up that muscled ass of yours!" The guy whose voice you heard falls to the ground, as he lays there with tears in his eyes you realized that it was your lab mate from science class John.

John was a lanky Mexican boy with an ass that just wouldn't quit and soul stealing lips, if the rumors were to be believed, he was a bit of a snarky ass hat at times but was an all around nice guy.
