Before the next appointment

With shakey hands I stood in the bathroom and shaved my crotch area. I have actually never done this before, so I'm extra careful with a blade so close to my genitals. I've heard once you cut your bush, your dick looks bigger, but in reality mine just looks like a small afraid worm in my hand. I hope Sarah might like it as I put the razor away and observe my hairless crotch area. It looks smooth but also pretty weird. The way my hair just stops and starts again on my thighs. Better cut it a bit more for a smoother transition. Well, now the hairline is just in the middle of my thighs. That looks even worse. I keep on shaving and shaving before I realize I'm practically shaving my whole legs. The feeling of letting the razor slide over my legs and then feel my hairless smooth skin with my fingers is kind of addicting.
Oh fuck I'll have to strip in front of Dr. Carter again. He'll see my hairless legs as well what the fuck am I doing. I have to lean forward to finsih the ast stroke towards my feet and I feel my cock pressing into my stomach. As I look down I see it's hard and throbbing. But why? Because of the smooth sensation? Or mabe because I think about stripping in front of the doctor again. Fuck maybe It's just because I thought of Dr. Carter. I bite my lower lip as I lay down the razor and instead wrap my hand around my little dick, which just vanishes beneath my fingers. I start stroking myself, why exactly I dont know. But after just a couple of strokes I begin moaning and bucking my hips, when a knock on the door makes my heart jump out of my chest.

"How long do you need in there, twerp?", my big sister Meg calls out. Quickly I grab a towel and cover myself right as she walks in on me. Without a word she removes her top and with jsut a bra on stands in front of the mirror and starts putting on make up.
"What the hell?", I shout out: "You cant just barge in like that!".
"Of course I fucking can, what do you wanna do about it, idiot?", she snarls as she looks me up and down: "Where you shaving? But not your face, huh?". SHe laughs in a mocking tone.
"I guess Sarah likes it prim and proper", her eyes not leaving my legs.
"Shut up and get out!", I shout again.
"Did you... did you shave your legs as well?!", she burst out laughing.
"It's for the doctor!", I defend myself.
"Oh right you're a patient of Carter as well now, right?", she says and I could swear she bit her lip: "I can see why he would want you to shave".
"Why?", I ask but she ignores me. She looks down at the small but noticable bulge in the towel.
"Thinking about Sarah? Or excited about your appointment?", she laughs again with that mocking tone and presses her breasts together: "Or just hot for your sister, loser?".
My head burns bright red. "Shut up! Shut up!", I cry out as I storm out of the bathroom.
"Don't be like that, Marcus. Its perfectly normal for guys like you", she calls after me: "Have fun with Dr. Carter. And say hi to him from me".

I run into my room and shut the door as I hear her viscious laughter echo through the house. I let the towel drop and look down at me. My legs, my balls and dick completely hairless. It feels... good. My legs are shaking but my cock is throbbing and leaking precum as I grab some clothes to go see Dr. Carter.
