Amanda had almost forgotten about you in her gym bag as she walked into her condo. Going up the elevator and into her simple living room, she noticed she was hungry and had some cleaning to to. She closed the blinds as she made her way through the few rooms in her apartment. Tossing her gym bag onto her bedroom floor, she striped out of her running clothes and into some boy-briefs, an old bra, and a tank top. She grabbed a load of laundry from the hamper, put it in to wash, then went to eat and clean.
After a quick meal and scrub of the bathroom and kitchen, she came by to put another load of laundry in the wash - this time from the gym bag. You feel her footsteps get closer and feel the bag open up. With the reaching in of her hands to grab gym clothes you can feel your new, longer and ever-hard length. As Amanda pulls the clothes she is going to wash out of the bag, you pop out as well! Amanda stops. Noticing you seem longer, but rationalizing that she didn't get a good look at you before, she is a little turned on... "I think my chores are pretty much done" she says self-consciously. She thinks you can't hear. That was part of the bet, right? It was.
She turns to finish changing the laundry, biting her lip and reflexively trying not to think about you or your form. But it is just a reflex, and you feel her footsteps return... slower.
It is strange and very erotic to Amanda, this using of someone without their participation. She wouldn't have thought it was but now that her friend is a simple piece of silicone the moment is real. She takes off her tanktop and lets it fall to the floor. She wonders if she should set limits what she does with you. The bra follows the shirt, thrown behind her. The two of you aren't romantically entangled and she doesn't know if fucking herself on you would bring that on. She picks you up by the outside of your skin, above the shaft and amidst the fake pubes. But the whole nature of the betting game had turned sexual so fast, Amanda decided she would just have fun with you and see what happened in the morning. Her free hand slides her panties loose and she walks out of them.
You feel her left hand cup your head and then slide gently down the shaft halfway as she brings you up to her lips. Warm, moist, air comes from what must be her mouth - you are excited for whatever is happening! You can feel how taught and full you feel in your penis and balls, but how empty and loose the pant part of you is. Her lips connect, freshly licked as they are so wet. She kisses your head, standing next to her bed. You want her to put you on or put you in It doesn't matter which or where!
