The first orgasm had lessened Kyle's sensitivity a bit, and it took a few minutes for his dick to get soft again. Jen still had 4 minutes of fucking frenzy to go, and continued sliding up and down his shaft, dropping herself so intensely onto him that her pussy cream rubbed onto his balls. By this point, Kyle couldn't feel his legs, and his vision was blurring. Jen's massive orgasm climaxed, and she crumpled onto him. The pressure on her breasts sent more milk spraying against his body and turned him on from their closeness. He continued to milk her as she devoured his lips, grinding her labia on his dick again.
It was slight, but it counted. Kyle, nearly depleted, shot two or three thin streams of cum forward, into the underside of her tits. Even though the four minutes of overtime had been about to pass, the curse ensured that Jen would not stop without a fourth.
Her mind raced, thinking of another way to get him off, as intensely as possible. She began to cup her hands, scooping whatever fluid she could find off of the floor and drizzling it over his dick. He watched her, confused, mesmerized, and a little scared. She then did the same to her backside, and her intentions for Kyle became clear.
Once she had sufficiently lubed up, she tuned away from Kyle's face and pushed him into her tight, virgin ass. Tight, in fact, was an understatement. Kyle's dick resisted at first, feeling almost crushed and going numb. Jen fucked him until her legs were shaking and she was barely able to keep herself up. She fell back onto him, his cock still in her, and squirted across the bathroom floor as Kyle started to pleasure himself with her colon. Jen, however, was not a quitter. She ignored the burn in her legs and insides and slid up and down his cock, moaning loudly and cumming multiple times. Finally, she felt his dick pulse, and a button of cum emerged from his tip. She collapsed on the floor, still leaking breast milk, lube dripping from her holes. Her hair and face fell into a puddle, and she was too exhausted to wipe herself clean, passing out on the floor.
Kyle laid for a while as well, his mind almost unable to process what had happened, before he dressed himself back up and walked late to class.
"Mrs. Stower?" he asked his teacher as he entered. "Sorry I'm late; I was just fucking Jen in the girl's bathroom. She brought me in there and started it, and really wouldn't stop for the longest time. Drained my balls pretty well, and milked herself pretty well too, I tell you. She's passed out in there - guess I really made her cum that hard." He smirked and laughed; a few of the guys sat back shamefully in their seats as the girls next to them leaned forward curiously to get a better look at his crotch and the liquids on his clothes.
"Jen? I thought she was a virgin! Sure, she dates around, but she was saving herself... well, I suppose I can go check on her at the end of the day. Shame on her for seducing a male in her own gender's bathroom - what a slut. Why don't you go home and change into something less... sticky? I'll excuse your grade for this period."
