You saunter into Jenny's yoga studio, feeling a bit self-conscious in the skintight women's yoga pants she lent you. Your cock, despite your best efforts to will it down, is already half-hard in the constricting fabric. You can feel the weight of the four women's gazes on you as you take your place at the front of the class, right next to Jenny.
"Alright, class, let's get started," Jenny says, her voice dripping with false cheerfulness. "Today, we're going to be working on some new poses, and Jack here is going to be our demo model."
You swallow hard as Jenny positions you into your first pose, her hands lingering on your hips and inner thighs as she adjusts your stance. You can feel the heat radiating off her body, and the smell of her perfume is intoxicating. You steal a glance at her massive tits, barely contained in her tiny sports bra, and feel your cock twitch in response.
"Keep your legs spread wider, Jack," Jenny says, her voice husky. "That's it. Now, slowly bend down and touch your toes."
You do as she says, feeling the fabric of the pants stretch taut over your bulging cock. You hear a few gasps and giggles from the other women, and you can feel your face burning with embarrassment.
"Very good," Jenny says, her hand brushing against your ass as she helps you straighten up. "Now, let's move on to the next pose."
You go through pose after pose, Jenny's hands constantly on your body, adjusting, guiding, touching. You can feel your cock growing harder with every touch, and you know it's starting to show through the fabric of the pants.
"Jack, what is going on down there?" Jenny asks, her voice exasperated. "You're supposed to be focusing on your breathing and your form, not getting a hard-on."
"I'm sorry, Jenny," you say, your voice strained. "I can't help it. You're just so...touchy."
Jenny rolls her eyes and grabs the waistband of the pants, pulling them down in one swift motion. Your massive cock springs free, fully erect and throbbing. The women around you gasp, and you can feel their eyes on your dick.
"Well, I guess you'll have to finish the class naked then," Jenny says, a smirk playing on her lips. "Lesson learned, Jack. No more distractions during yoga."
You finish the class in a state of blissful humiliation, your cock fully erect and on display for the entire class to see. As you bend down into your final pose, you catch Jenny's eye and give her a wink.
"You're a dirty boy, Jack," she says, her voice low and seductive. "But I think I might like it."
You grin, feeling a thrill run through your body. Maybe this yoga thing isn't so bad after all.
