Valentina - The Sexual Health Fair

After the mess on the transit pod, Valentina barely had time to grab a quick shower. The wet towel clung to her skin as she stepped out, her huge breasts swaying heavily with each movement. Her bra, more decorative than supportive at this size, struggled to contain her chest as she slipped into her uniform—a shirt already strained against her massive curves.

She strolled into the university courtyard, where the annual Sexual Health Fair was in full swing. Booths were everywhere, with students milling about, picking up freebies, and engaging in hands-on demos. A familiar buzz of casual sexual energy lingered in the air, perfectly normal in Mammopolis. Just another day.

She was making her way to class when a voice cut through the noise.

“Hey! You there!” It was a booth attendant, waving eagerly.

Valentina paused, one hand still adjusting her shirt. “What?”

“We’ve got a breast health demo coming up, and well…” His eyes lingered on her chest, though it felt more like routine admiration than anything predatory. “You’d be the perfect model.”

“Of course I would,” she muttered, almost amused. “And what exactly do you need me for?”

He gestured toward a small stage where students were gathering. “We’re teaching hands-on breast exams. You’d be a live example for the class, and trust me, with your size, they’ll learn a lot.”

Valentina gave him a flat look. “You sure this isn’t just an excuse to feel me up?”

“Nah, it’s strictly educational,” he said, grinning in a way that suggested he wasn’t entirely against the idea. “We’re teaching anatomy, care, sensitivity checks—all that important stuff.”

A female professor chimed in, backing him up. “It’s for the students. With your, uh, proportions, you’d be offering a unique opportunity for them to understand breast health in a real-world scenario.”

She glanced around, noting several eyes already on her. A few students had stopped what they were doing, clearly interested in the developing situation. “Fine,” she said, shrugging. “But make it quick.”

They guided her to the stage, the crowd growing larger as word spread. Her shirt was unbuttoned in front of everyone, her massive breasts spilling forward as her bra strained to contain them. The fabric barely hid her nipples, and the eyes of every person in the crowd were locked on her chest.

The professor began explaining the basics, but the students’ attention was already wandering. “Who’s first?” she asked, signaling for volunteers.

A young guy in the front wasted no time stepping up, his face flushed with excitement. “So, I just… feel them?”

“Right. You’re looking for lumps or anything abnormal,” the professor instructed.

He swallowed nervously, then placed his hands on Valentina's chest. His fingers dug into her soft, heavy breasts, squeezing experimentally. His breathing hitched as he explored her curves, his eyes flicking up to meet hers.

“They’re… softer than I thought,” he murmured, his thumbs brushing against her nipples through the thin fabric of her bra. They hardened slightly at the contact, and he paused, almost embarrassed by it.

“Yeah, that happens,” she said dryly. “You done?”

He nodded, stepping back reluctantly. As he moved away, another guy from the crowd shouted, “Dude, you missed the best part! Check the nipples!”

The guy froze, glancing back at her with a sheepish grin. “Uh, should I?”

Valentina raised an eyebrow but didn’t move to stop him. “Knock yourself out.”

He reached back out, fingers closing around her nipple through the bra, giving it a gentle squeeze. It hardened instantly, and a murmur rippled through the crowd. A few people had already started touching themselves—guys openly jerking off to the scene unfolding on stage.

She smirked, noticing the growing heat in the air. “Satisfied?”

He stepped back, flushing even redder than before. “Uh, yeah. Thanks.”

The professor barely kept a straight face as the next volunteer, this time a girl, came forward. Her hands were more tentative, but she was clearly just as curious. “They’re huge,” she whispered, fingers tracing the underside of the girl’s breasts. “Do they always stay like this?”

“Pretty much,” Valentina answered, folding her arms behind her head as if she were lounging. “I get bigger when I’m close to ovulating, though.”

The girl laughed softly, squeezing a bit harder now. “You must drive guys insane.”

“They tend to lose their minds,” she said, watching as more guys in the audience began openly masturbating. One of them had his pants halfway down, stroking himself shamelessly.

Another student shouted, “I had her last week—didn’t disappoint.”

She shot him a glance, amused. “Still thinking about it, huh?”

“Hell yeah,” he grinned, pumping his fist as he kept jerking off in front of everyone.

As the next guy approached, clearly excited, he blurted out, “You ever get titfucked during these demos?”

She laughed, the sound low and unbothered. “Not usually. But if you’re that ****, you might get lucky.”

His hands were trembling as he reached out to cup her massive breasts. “Shit, they’re bigger than my head.”

“You’re not wrong,” she teased, arching her back slightly to give him more access. “Go ahead, measure them up against yourself.”

Without missing a beat, he did just that, pressing his head between Valentina's breasts. The crowd went wild, several people cheering and jeering as he buried his face in her cleavage. “Holy fuck,” he muttered, clearly overwhelmed.

One of the guys in the crowd, stroking himself furiously, shouted, “Show us the size of his dick!”

She smirked, tilting her head. “You wanna show off for the crowd?”

The guy pulled back, his face red but clearly game. He dropped his pants, his cock springing free, half-hard already from the attention. “Think I’m big enough for you?”

She sized him up, eyes flicking down to his cock. “You’re bigger than most,” she admitted, shrugging. “But let’s see if you can handle the job.”

The guy grinned, looking ready to drop to his knees then and there, but the professor cleared her throat loudly. “This is still an educational demo,” she reminded them, though her voice lacked conviction. Even she was getting caught up in the heat.

Before things could escalate further, one of the onlookers came up from behind, his own cock out and ready. “Mind if I finish on you?”

She glanced at the growing line of guys, all of them jerking off furiously now. Her eyes flicked to the clock. “Alright, fine. But make it quick.”

With that, she leaned forward, presenting her chest as guy after guy lined up, jerking themselves over her exposed skin. One by one, they came, splattering her tits with cum as the crowd cheered them on. She barely flinched, treating it like a routine transaction, her gaze distant as each guy finished on her.

When the last one had his turn, she stood up, buttoning her shirt over her cum-streaked chest with a sigh. “Alright, boys, that’s it for today. Gotta run.”

Valentina turned, leaving the stage as the crowd dispersed, her shirt already stained and stretched from the wild demo. Just another day in Mammopolis.
