apparently it was more than just looks...

the moment youre home you strip off the uncomfortably tight jeans planning to change them for something more fitting... but when you find a better pair and start putting them on, you absently look down while doing so and something is quite different. there just below the abs you work so hard to maintain, the the light brown tuft, isnt the cock and balls youre used to seeing, but a pair of feminine folds.

You freeze momentarily... before letting out a panicked scream. Quickly enough it draws your older sister into the room, who when asking whats wrong, has to muddle through your semi coherent babbling about "it's gone" before rolling her eyes.

"Oh, is that all?"

"What do you mean is that all?!"

"ooh, fitst time its happened to you? gotcha. yeah this happens to everyone. its not gone you just changed. loose clothes, cock, tight clothes, vag." she explains, patting her skirt in a way that makes it clear theres something underneath youre sure she didnt have yesterday. this doesnt make any sense... but with the crisis seemingly over, she wanders off. in no hurry to stick around while her brother has his pants down.
