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."

She shoved him backward onto the bed, eyes blazing with hunger as she peeled off her sports bra, freeing those full C-cups that bounced free, nipples already stiff. “Stay right there while I get comfortable, my little panty thief.” Jamie hooked her thumbs into her shorts and shoved them down, her thick eight-inch cock springing out, already half-hard and glistening at the tip. She stepped out of them completely, then grabbed the discarded black lace panties from the floor and dangled them in front of his face.

“Open wide.” Alex parted his lips without hesitation. She stuffed the crotch against his tongue, making him taste her lingering musk. “Suck them clean while I watch that pathetic little dick twitch. Good sissy.” He moaned around the fabric, cock leaking onto his stomach as she stroked herself slowly to full hardness, the veins standing out along the shaft.

Jamie yanked the panties free and tossed them onto his chest. “Put them back on. Now. I want to see that bulge while you choke on me.” Trembling with need, he scrambled to step into them again, the lace snug around his balls and shaft, tenting obscenely. She climbed onto the bed, straddling his chest, and slapped her heavy cock against his lips. “Beg for it like the slut you are.”

“Please, Jamie, let me suck your girlcock. Use my mouth. Make me your sissy whore,” he gasped. She thrust forward, burying half her length in one smooth push. Alex gagged happily, lips stretching wide as she fucked his throat with long, deliberate strokes. Spit ran down his chin while her balls tapped his face. One hand tangled in his hair, holding him steady; the other pinched and rolled her own nipple.

“That’s it, take it deeper. Look at you, already drooling for mistress. You’re going to wear my panties every day from now on, keep that hole ready for me.” She pulled out long enough for him to gasp, then shoved back in balls-deep, grinding against his face until his nose pressed into her smooth pubic mound. When she finally withdrew, a thick strand of spit connected his lips to her cockhead.

Jamie flipped him onto all fours, yanking the panties aside to bare his smooth ass. She spit on his tight hole, working two fingers inside roughly while he whimpered and pushed back. “Fuck, so eager. This slutty little pucker is mine now.” She lined up and slammed home in one thrust, burying every thick inch. Alex cried out in pure pleasure, cock throbbing untouched inside the lace as she pounded him hard, hips slapping against his cheeks.

“Tell me what you are,” she growled, reaching around to squeeze his covered dick.

“Your sissy slut! Your panty-wearing bitch! Fuck me harder, Jamie—fill me up!”

She hammered into him relentlessly, balls swinging, one hand cracking sharp spanks across his ass until it glowed pink. Her free hand jerked him through the soaked lace in time with her thrusts. The dual assault pushed him over the edge first; Alex screamed into the sheets as he came hard, thick ropes pulsing out and soaking the front of her panties, his hole clenching rhythmically around her cock.

The tight flutter dragged Jamie right with him. She buried herself to the hilt and roared, pumping hot loads deep into his ass, flooding him until cum leaked out around her shaft and dripped down his balls. She kept grinding through the aftershocks, milking every drop into him, then finally pulled out with a wet pop.

Jamie collapsed beside him, pulling him into a possessive kiss while her fingers idly traced the cum-smeared lace still clinging to his spent cock. “You’re sleeping in those filthy things tonight, and every night after. My personal sissy roommate. Understood?”

Alex nuzzled against her breast, spent and glowing. “Yes, Jamie. Anything you want. I’m yours.” She smiled, already planning the next load he’d take, their new arrangement sealed in sweat and seed.
