Limits of the Flesh

Chapter 1: The Agreement

Jesper leaned against the mahogany table, eyes gleaming with scientific hunger. "Tina, darling, the female body is a marvel of endurance. I want to test its throat limits—five minutes with a thick dildo, tied, filmed. Your reactions, every gasp and tear. What do you say?"

Tina arched an eyebrow, her posture radiating command as she circled him like a predator. "Test the limits? Cute. But let's be clear, Jesper—you're the lab assistant here. I'll let you use my body because it amuses me, and because watching you squirm while I take it will be delicious. Film it? Absolutely. I want to replay how my eyes water and turn pleading, just to mock you later. Get that timer ready, and don't you dare look away from my gaze."

Her words were sharp, laced with wit that made his pulse quicken. She stripped with deliberate grace, revealing smooth skin already glistening with anticipation. "Tie me? Fine, but make the knots tight—I want to feel the restraint, not submit to it. And Jesper? If your cock gets hard watching, you better save that for after. My pussy's already wet and dripping at the thought."

He bound her wrists to the bedposts, her strong legs spread just enough to tease. The thick dildo gleamed as he positioned it. "Timer set for five minutes. Eye contact the whole time, Tina. I live for those pleading looks."

She smirked, horny and unyielding. "Start it, scientist. Let's see whose limits break first."

At thirty seconds in, the dildo slid deep. Tina's throat bulged visibly, her body tensing then relaxing with controlled power. Eyes locked on his, watering slightly but defiant, not pleading yet. Saliva dripped from her chin as she panted through her nose, chest heaving, nipples hard. Her ass clenched against the sheets, pussy visibly wet and dripping onto the fabric. Jesper's own cock strained hard in his pants, but he held the camera steady.

"Look at you," he murmured, voice thick. "Already sweating."

Tina's eyes flashed with challenge even as her throat worked around the intrusion. The first minute ticked by, her reactions building—subtle gags, tears gathering—but her gaze never wavered, strong and seductive, promising an explosive release once the experiment ended.
