Head home for some solo fun

The doctor helpfully walks you through pairing the implant to your phone and explains a few more of the features, but encourages you to spend time discovering all of the functionality on your own. You thank her and pull your clothes on before heading back home.

Eager to test out your new toy, you rush home. Imagining the fun you could get up to gets you hard again, and you cover your erection as best as you can. You sit down near the back and cover your crotch. Your jeans tent at the thought of lying back and jerking off remotely. That pleasure from the doctor's office was probably only the beginning. If what you read was true...

You shake yourself to attention. The thought got you so hard. Your chest starts pounding at the idea of walking off the bus with a boner this obvious. Looking up, you see a girl sitting by the door. She makes eye contact and smiles. "Oh crap," you think, smiling back awkwardly as you recognize her. She lives in the same dorm as you. There's no way she wouldn't notice the tent in your pants, especially if she's getting off at the same stop and walking to the building.

She gives you a bit of an odd look. You can imagine the redness in your face as you look away, trying to think of a way out...
