Girlfriend's Panties Ignite Roommate's Sissy Lust

Alex had always been careful. In the cramped two-bedroom apartment he shared with Jamie, a stunning trans woman from his college psych class, secrecy was his survival skill. At 20, with a lean build, smooth skin from his obsessive shaving routine, and a hidden stash of women's clothes buried in the back of his closet, Alex harbored a filthy little secret: he was a crossdressing sissy at heart. Jamie, 22, with her long raven hair, piercing green eyes, full C-cup breasts from hormones, and a confident strut that turned heads, had no idea. Or so he thought.

They'd been roommates for six months, splitting rent to afford the off-campus spot near campus. Jamie was out most nights—partying, hooking up, owning every room she entered with her dominant vibe. Alex admired her from afar, jerking off to fantasies of kneeling at her feet. But he never crossed the line. Until laundry day.

The washer-dryer combo in their tiny utility closet hummed as Alex pulled out a mixed load. His boxers, her thongs, socks tangled together. He sorted mechanically until his fingers brushed something silky: a pair of Jamie's lacy black panties. High-cut, sheer mesh panels, a delicate bow at the front. The scent hit him—her musky perfume mixed with faint pussy juice and sweat. His cock twitched instantly.

"Fuck," he whispered, heart pounding. He glanced at her closed bedroom door, then stuffed the panties into his pocket. In his room, door locked, he stripped naked. His body was primed for this: slim hips, a pert ass from squats, five-inch dick already leaking pre-cum. He stepped into the panties, the lace hugging his smooth balls and shaft, the fabric riding up his crack like a promise. Mirror check: he looked slutty, feminine, his erection tenting the front obscenely.

Sissy fantasies flooded him. Jamie catching him, laughing, calling him her little bitch. Forcing him to wear more, to worship her thick girlcock. He stroked through the lace, moaning softly, hips bucking. "Oh god, Jamie, please... make me your sissy..."

That's when the door flew open.

Jamie stood there, gym bag slung over her shoulder, sports bra and shorts clinging to her sweat-slicked curves. Her eyes locked on him—panties on, hand pumping his bulge. Shock flashed, then a wicked grin spread across her plump lips.

"Well, well, roommate. Stealing my panties? And look at you, all hard and slutty in them." Her voice was low, commanding, dripping with amusement and heat. She dropped her bag, sauntering in, locking the door behind her. At 5'10" in sneakers, she towered over his 5'7" frame.

Alex froze, dick throbbing traitorously. "J-Jamie! I—I'm sorry, I found them in the laundry, I didn't mean—"

"Shut up, sissy." She stepped close, grabbing his chin, forcing his eyes up. Her touch sent sparks through him. Up close, her bulge was visible in those tight shorts—a reminder of her eight-inch cock, thick and veiny from what he'd glimpsed in the shower once. "You've been hiding this side? Fantasizing about me? Admit it."

He whimpered, nodding. "Y-yes... I... I want to be your sissy. Please, Jamie, don't be mad."

Her laugh was throaty, dominant. "Mad? Baby, this is hot. You've got potential. That ass in my panties? Perfection. But you're not just trying them on—you're begging for guidance. Say it."

"Please," he gasped, stroking again without thinking. "Guide me, Jamie. Make me your sissy slut."

She smirked, eyes gleaming with lust. "Strip them off. Slowly. Show me that needy hole."

Trembling, Alex peeled the panties down, kicking them aside. Naked, exposed, his cock bobbed. Jamie circled him like prey, slapping his ass lightly. "Good girl. Or should I say, good boy? No—sissy. My sissy. Now beg properly."

"Please, Jamie! Teach me to be your panty-wearing bitch. I need it!"

Her hand wrapped around his throat—not choking, just owning. "That's my slut. We're doing this right."
