The social experiment

You walk briskly down the crowded campus pathway, headphones firmly entrenched in your ears and a textbook clutched tightly in one hand. As you pass by a bench, you can’t help but notice two girls giggling and whispering to each other. They are both wearing skirts that flared out temptingly with every movement they made, revealing tantalizing glimpses of their matching panties.

“Can you believe it, Sarah? He totally checked us out!” the blonde girl tittered, her hand reaching down between her legs to fondle her crotch suggestively. “I swear, he was practically drooling!”

Sarah, a brunette with equally alluring curves, giggled even harder, her own fingers tracing circles on the fabric at the bottom of her skirt. “Well, who can blame him, Emily? Our new little project is just too irresistible!” she giggled.

Your heart is racing, and your palms start to sweat as you continue to class, unable to shake off the image of those barely concealed panties. You can barely pay attention in class as you keep thinking about the two girls, your mind wandering down forbidden paths. By the time class ends, you practically bolt out of your seat in anticipation of seeing the girls again.

As luck would have it, you spot them sitting on the same bench they’d been on earlier, their legs still slightly apart. You walk by slowly trying not to be so obvious about trying to get a closer look.

“Excuse me,” the brunette Sarah calls out to you, “would you mind answering a few questions for us.”

You point at yourself and they both gesture for you to come over.

You can’t believe your luck! The two girls who had been teasing you all day with their panties are actually asking for your help? You quickly make your way over to them, trying not to appear too eager. “Uh, sure, what can I do for you?”

“Thank you so much!” Emily, the blonde girl, chimes in. “We’re doing a project for our psychology class on men’s preferences between cleavage and panty exposure.” She flashes her ample cleavage at you before pulling her top back into place.

“That sounds interesting,” you manage to squeak out, your eyes glued to the small triangle of fabric peering out of the bottom of Sarah’s skirt.

After quick introductions, Sarah starts, pulling out her phone from her bag. “So, we have these pictures,” she flicks through a few photos before holding it up to show you two images side by side: one with a woman in a revealing top that showed off plenty of cleavage, and the other with another woman wearing a more modest top but sitting in a way that exposed just enough panty-line to tease.

“Now, John,” Emily chimes in, moving closer to you so their skirts brush against your legs ever so slightly, “which one do you think is more attractive?” she asks, her breath tickling the side of your neck.

You can barely contain yourself as you stare at both pictures, torn between the two options. The first picture has a gorgeous woman with ample cleavage on display, and it’s definitely... attractive. But then there’s the second photo, and while the girl isn’t showing off nearly as much skin, something about seeing that little sliver of her panties peeking through her skirt has your pulse racing.

“I-I...” you stammer, unable to bring yourself to admit what your real preference is. “They’re both... really good,” you finally manage to utter lamely.

Emily and Sarah giggle in unison, clearly enjoying your discomfort. “Oh, come on, John,” Emily coaxes, sliding her hand up your leg and gently squeezing your thigh through your pants. “We won’t tell anyone what you really think.”

“You know you want to tell us,” Sarah adds, mirroring Emily’s movements on the other side of you. Their skirts are practically hugging your crotch now, their warm thighs rubbing against you in slow, sensual circles.

“I-I... uh...” you stammer out, your voice cracking under the onslaught of arousal flooding through you. “I-I think I... uhm...” you stutter, unable to form coherent words anymore as your mind is consumed by thoughts of their panties against your cock.

“Maybe you need better examples,” Sarah says while grabbing you by the hand and leading you towards the sociology building.

You stumble after them, completely entranced by their seductive teasing. They lead you into the empty classroom, and both girls sit on top of a desk. Sarah spread her legs fully exposing her black lace panties. Emily meanwhile pulls her top off revealing her large D-cup breasts that are barely contained within her bra.

“Which do you like better now?” Emily asks sweetly.

You can’t believe what’s happening, but your cock is rock hard in your pants, throbbing with desire for both of them. “B-both... they’re both so...” you manage to squeak out, unable to contain the growing tent forming in your pants.

“Oh, but you must choose one,” Sarah coos teasingly. She reaches down and starts rubbing herself through her panties, making wet sounds that echo in your head. Emily watches with a mischievous grin on her face before jumping down, walking over to you and all but shoving her cleave in your face.

“I-I-I...” you stammer, feeling like you’re going to pass out from the sheer intensity of both women’s alluring displays.
