A horny classmate walks in, ready to fuck.

"Y-yeah? Come in...?" Johnny said after hearing the knock. It didn't occur to the nutting and wall-humping boy why someone else would knock before going to one of the stalls in here or to use one of the holes, unless the one who knocked was-- *Gasp!* Johnny made a panicked and confused eye-contact with the silhouette of a girl who now walked towards him. "Bu-but-but you can't be-- *aah* ---in here, y-you're a...!" Whispering seductively to him, the girl answered. "Yeah, I know, mouse boy, and I'm not staying here." The curvy, cream brown bunny grabbed his dick and stopping Johnny from thrusting. "I saw you earlier and knew then that I had to find you and formally for a fucking." she said confidently and licked her plump bunny lips. "Those huge knuts of yours are wasted filling up the ejaculation disposal system, anyway."

Johnny had a million thoughts flying through his head in response to this situation he was suddenly thrust into. Secretly, he had wanted something like this to happen, and he certainly wasn't complaining about how the soft hands of his mystery friend on his dick was sending waves of pleasure up his spine. And that was just an appetizer! Stammering, Johnny answered the only fully formed thought he could muster right then. "Sex between students isn't allowed in the restrooms, miss." The obviously quite horny woman rolled her eyes at the comment, then quickly regained that electric, seductive look in her eyes. "So, we'll just do it outside then! Come on!" she said to him, almost grabbing him as she guided him out of the boys' restroom.

She popped her head out the door, looking to see if anyone was in the hall. Johnny hurriedly took his clothes back on. "It's clear. Go now!" she exclaimed. Johnny followed behind her as they made their way to an exit.

Soon enough they reached a spot that the bunny was found suitably private (and where Johnny also agreed too), so behind a large bush not at all far from the school, the creamy brown woman began undressing and asked the grey and white mouse to do the same. "Isn't this a little hasty? I don't even know your--" She cut him off, saying. "Lorraine. And what's yours?" Johnny replied with his own name. A moment later, they were naked and Johnny was presented with Lorraine's naked body.

She was taller than him, with perky, large breasts the size of yoga balls and dark nipples. She had a small, bushy bunny tail above an ass that, like her boobs, was much larger than her own head, and it rounded her out to have absolutely perfect hourglass proportions.

Lorraine got down on all fours. Johnny's semi-erect, foot-long penis hovered infront of the woman presenting herself to him, and he hesitated to plunge in, despite his instincts to do so. "What's the hold up, Johnny?" she asked him. Johnny in turn explained that he'd never done it before with a girl, to which Lorraine was very understanding and reassuring. "Start it slow, and you'll get the hang of it. Now go on, I'm so WET!" she commanded the virgin, as she playfully wiggled her yoga balls-sized cheeks and presented her womanhood.

Swallowing nervously, but then exhaling confidently, Johnny guided his huge dick into her hole and pushed it in. Lorraine's walls pressed greedily down on the mouse boy's dick as it went in and out. The wetness of Lorraine combined with Johnny's own generous contributions of pre-cum quickly lubricated the passage Johnny's dick took and helped him move quicker. *unf* *unnf* Lorraine's pleasured gasps reaffirmed to her that this was a good choice of boy to fill her desires with.

Johnny grabbed on to the sides Lorraine's hips, pushing her ass together and sped up his thrusts further. *pleasured groan* Through gritted teeth and some heavy panting, Johnny complemented the bunny on her soft butt and how good her pussy felt. He liked that her butt was very big. She replied saying that she liked that how his penis was also very big, then wondering if he too was having a good time. Johnny thought the answer was so obvious that he shouldn't even have to say it, but he did, confessing this was the best feeling he'd ever felt.

Seeking to try out what ass expansion during intercourse felt like, Lorraine went ahead and gave her hips and cheeks a little boost. Johnny felt surged of growth against his palms as they were filled with more Lorraine than before. It awakened inside Johnny in that moment that he preferred bigger than yoga ball-sized asses.

Johnny felt himself nearing his first of many loads to release inside Lorraine, and realized he should confess to his inability to control getting bigger, more productive balls. "I should warn you, Lorraine. I cum loads." She was happy to hear it, encouraging him to give it his all, and keep going still. She was stretchy, she could take alot. She'd taken huge loads before and knew her body was really, really elastic. She'd love for someone absolutely hung like Johnny to fill her up. She would drain him, or pass out trying. Oh, what better fate to drain him every day endlessly, to be Johnny's big, heavy, warm, cum covered breeding pillow. Was this love she felt? Had to be. Johnny would be her boyfriend now.

Johnny sped up his trusts into the bunny that laid down in the grass before him. He was about to cum, and he couldn't restrain the **** of which he was about to ejaculate. "OOOHHH SHIIIII--!!!" he yelled as he came inside Lorraine's stretchy bunny stomach. It filled and filled, bulging down into the grass with gallons of mouse cum. Forceful globs of spunk flew from the side of Lorraine's womanhood to the sides of both students, but most of it still seemed to flow in unrestrictedly. Rope after rope of warm, sticky goodness shot out his tip and Johnny pressed down hard on Lorraine's soft bunny hips, as to somehow better squeeze his dick juices into her harder than her inner walls already were.

Johnny was dazed, the world had darkened in the corners of his eyes and his head had swung all the way back to cope with the waves of ecstatic pleasures sex brought him. He pulled out his softening dick using what remained of his alertness and willpower, seeing it still spill with what little was being pumped from his scrotum as it shrunk back down to its non-expanded size. All its contents were transferred to the insides of a very happy bunny girl.

Both of them need a rest after that... They also both felt themselves needing more doses of that for the days to come, as they both took the easy decision after waking back up to become a couple.
