Amanda finds herself needing to go to the bathroom in the middle of the night. Remembering that she hadn't gone before bed, she starts to get up... but stops. What is that feeling? Suddenly, she remembers why she fell asleep naked on the bed!
You, of course, don't sleep, being a silicone body part. You have felt this need to "go" for a while and felt awkwardly content playing the part of holding it. This is so weird.
Amanda hops off her bed and walks to the toilet, you smacking between her thighs as her hips sway. She decides, groggily, to go for it. She can feel the moistness in her penis and the clenching in a weird place. Lifting the seat and grasping you, she feels around and "lets go." The urine flows out with no problem and she manages the aim. Reaching down for a piece of paper, she realizes. "Oh! Sorry..." Remembering you can't hear her, she still mentally apologizes, wondering if that was weird.
It was, but since you are a penis it kinda feels normal?
After wiping, Amanda investigates. She lifts up the edge of the silicone with one hand and feels around your length with the other. Still attached. Moving back to the bedroom, she puts the hand farther underneath and finds her sex. The mess is still there, along with her womanhood. That needs to be cleaned. She notice that you are still rock hard, along with the resultant feeling of being hard. Also, when she lifts you away from her skin, the base is less stable and you can be flopped around. She feels her balls and the trail to her asshole. Such a weird feeling.
For you too... hope that doesn't happen.
