Erica freezes you in place

You lie on your back on the dorm room floor, breathing slowly returning to normal as the sounds of your roommate's shower reach your ears. You shiver as you lie in a puddle of sweat and other fluids, feeling Erica's juice run down your cock to the floor. With tentative fingers, you reach between your legs and start to play with your new equipment. You flinch as you touch yourself, still very sensitive from the earlier treatment. After softly touching the shaft, you softly run your fingers up to the head, caressing the tip.. You gasp at the sensation, and slowly swirl your finger, generating little pulses of afterglow pleasure. Your eyes close in satisfaction.

In your trance, you don't hear Erica's shower come to a close. She chuckles as she walks into the room again. "Of course my little slut is already playing with himself. Are you my horny little boy?" You nod meekly and croak "yes, mistress."

"Well that's good," your roommate continues, standing over you in a towel. "I expect my sex **** to be constantly ready for me like a little toy." Your heart flutters at her words. Is that what you are now? A sex toy? Some sort of living dildo? "Stop touching yourself," Erica commands, and you immediately obey, moving your hands to your sides. She taps a button on the phone and you feel an unfamiliar jolt run up from your crotch all through your body. It's like your muscles are buzzing with static electricity. You try to jerk back in surprise, but you... can't? Your limbs aren't responding to your brain. You're frozen in place! Erica chuckles again. "This little device is pretty powerful. What a high-end toy I have." Unable to respond, you just look up at her as she bends down and picks you up. It almost seems too easy for her to handle you as you're scooped up into her strong arms. She carries you over to your bed and lies you down. Still unable to move, you look up at her in confusion.

"Aw, is my little slut confused? Let me explain it for you. You're my little sex ****, right? Well I want you to be waiting here at home for me. Rock hard and ****, ready for me. That makes sense, right?" You try to speak up but you can't. Erica brings up the phone again and taps on a button. You feel a warm pulse of pleasure in your cock and you flinch. Then another. Then another. The pulses continue and you feel your arousal building again as you start to get hard. Putting the phone away in her pocket, Erica starts to pack up her gym bag. "This should keep you nice and horny for me when I get back. I'm heading out to the gym, then I might see some friends. I'll probably be out for a few hours and I'll want some stress relief when I get back." You stare in horror at her. She's going to leave you like this? For hours?! She finishes packing her bag, then walks over to your bed. "You're such a good boy." She runs a finger slowly up your erection and you moan in your throat. She teases the tip of your dick for a few seconds, building your pleasure, but suddenly removes her fingers. "Don't worry, you're not gonna cum while I'm gone." She scoops up a drop of pre-cum that's formed before shoving her fingers into your mouth, wiping them on your tongue. You taste cum.

She shoulders her bag, turns off the light, and leaves the room, plunging you into darkness. The pulses of pleasure in your dick grow in frequency and intensity, causing you to moan each time. The pleasure builds and you want nothing more than to reach between your legs and grab your cock, but you can't. Your eyes roll back in your head as you moan into the dark room, dick twitching as you approach a climax that will never come.
