You put on the cloths laid out for you, of course they replaced your boxers with underwear that would fit your slimmer build and lack of a bulge in front. Just the thought of not having a bulge weirded you out.
It felt weird walking around without a dick, you were just used to having it hanging down there, you could always feel that it was missing. Plus the feeling of having underwear flat up on your crotch felt so strange, like you're feeling something that shouldn't be possible.
You notice other boys walking in and out of school. Nobody seemed happy about this. Going into school on a weekend was bad enough, the reaction was tenfold when it ment losing your dick.
You wander the streets for a bit. It's the same city you always lived in. In urban areas like this it's not uncommon to see someone whose genitals don't match their body that well.
Eventually you decide to go to your girlfriend's house. She's still alone and she's probably going to be willing to fuck you like this.
As you turn onto the side street where her house is you spot her hanging out on the strip of sidewalk in front of her house. You see her beautiful slender form, you want to slide in between those legs. But you're reminded of the emptiness between your legs, you physically can't do that again. Only a few hours ago you were deep inside her and now you can never do that again.
You still have genitals though, even if their not the right set. Time to see what you can do.
