You head back to the dorm. Your roommate is out for the weekend, so you have the room to yourself. Curious, you take out the flashlight and remove your clothes. Standing in front of your mirror, you shine the blue light on your chest, watching your pecs grow and your hair grow thicker. You let the light trail down your stomach, firming your abs, and down to your cock. As you shine the light, it grows larger. While a respectable 4 1/2 inches soft and 8 inches hard, you feel it could be bigger and give it a shot.
The light thickens your cock and makes it bigger. Your balls plump up and you feel a sudden rush of testosterone. Your cock gets hard at this, and extends to a solid 10 inches.
"Woah" you remark in surprise. You stroke it and you notice it's more sensitive than it was before. As you stroke it, you hear a knock at the door. You walk to it and look through the peep hole and it's your girlfriend, Melissa.
"Hey babe, it's me, want to let me in?" She asks. You know what she's here for, she knows your roommate is gone. Melissa is about 5'6" and is very good looking. She has brown hair that goes below her shoulders and a very cute face. Her breasts are 34C with fantastic, perky nipples that you love to suck. With a nice waist and a great, firm ass, and long, firm legs (she is a volleyball player, after all), she is easily one of the hottest girls you know.
You open the door and she comes in. You're behind the door so nobody else sees you. You shut the door and lock it. Melissa turns to you.
"Hey," she says sensually, and comes over to you, "ready I see." She gives you a firm kiss on your lips and wraps her arms around you. Her firm breasts press into you, feel her nipples press into your chest.
She puts a hand onto your dick and strokes it. "Let's go to the bed." You suggest. She takes off her clothes on her way over and sits down, you watch her tits jiggle as leans against the wall. You shut off the lights and pull the shades. On your way to the bed you pick up the flashlight. "What's that?" asks Melissa.
"A very sexy light," you say, as you turn it on. You move to between her legs and she lays back. You stick out your tongue and run it along her slit. She moans a little and puts a hand on her tit, kneading her nipple. Wondering what will happen, you set it on pink and shine it between her legs. You notice that her vulva and labia become plumper, and her clit gets bigger. You turn off the light and go back to your job. You slide your tongue and immediately notice the difference. Melissa moans louder now. You tongue her clit and she yelps. "OHHH babe you know how sensitive I am! Ohhhh!"
But you don't stop. You slide a finger between her and start to finger her. First one, then two, then three. She moans and you can feel her pussy muscles start to contract against your fingers. She puts her other hand on your head and holds you close.
"OHHHHH YES! OHHHH!!" she screams as she orgasms. As she calms down, you take your face from her crotch and slide up her. "Wow that was as good as ever!" she says and she pulls you up to her and gives you a kiss. You feel your cock brush between her thighs and Melissa puts a hand on it and begins to stroke. Then she takes your cock.
