You look at yourself in your bedroom mirror and smile like an idiot. The nurse outfit you bought is fucking perfect. The dress is short and tight and you're pleased to see that the chest doesn't sag, even when it was obviously meant for a woman. You straighten your little cap and pick up the clip board on your desk. You walk into the living room to see your roommate on his laptop. He's probably working on homework, but that can wait. You clear your throat and walk in front of him.

"Karkat Vantas?"

"Yes, Dave, that's my name. I'm so fucking proud of you for finally figuring it-" When he finally looks up at you his jaw drops and his eyes scan your body. "-out…" He straightens his face and quirks a pierced eyebrow at you. "What the fuck are you wearing?" You ignore the question. Maybe if you stay in character, he'll just roll with it.

"It's time for your appointment, Mr. Vantas." You can see the red flush seeping in behind his freckles, but he still keeps his face hard.

"Is it? I don't think there's anything wrong with me, nurse." The last word is pointed. Come-the fuck- on, Karkat. You're trying to be sexy. The corner of your mouth turns up.

"It's normal to be embarrassed about impotence, sir." You point the last word right back at him and he looks like he's about to explode with how much he's blushing.

"I'm not fucking impotent, asshole."

"Then you'll be in and out after a few tests. Follow me." You start walking back to your room and you're actually kind of surprised that he actually gets up and follows you. You let him go ahead of you and you shut the door. "Go a head and take a seat on the bed for me.." He grumbles but does so; you sit the desk chair that you put by the bed earlier. You cross your legs daintily and pull the pen out of the clasp on your clip board. "Tell me, Mr. Vantas, how long does it usually take for you to become fully erect?" You're proud of yourself for not laughing at his face.

"I have no fucking idea." He grits out.

"Well, we can find that out today. How long do your erections usually last?"

"I don't know." He sighs. Good, he's giving in.

"Alright, we can do that also. I'm gonna need you to get comfortable for me, Mr. Vantas." He mumbles something under his breath as he shifts to where his back is against the head board.

You grab a stop watch off of the nightstand and sit on his shins, working at his belt and the fastenings of his pants before pulling them down along with his boxers. He's already a little hard, but you ignore it and start the watch before sucking the head of his cock into your mouth. He gasps and his hands fly to your hair, tugging a bit and knocking the small hat out of place. You slowly lower your head until he's nestled in the back of your throat. He moans and grips your hair, sending a shock of pain down your spine and making your cock twitch. You swallow around him and pull back, sucking at the tip before dipping back down. After a few bobs, he's completely ridged. You pull off, much to his verbalized dismay, and press the button on the stop watch.

"Hmmmm…8.46 seconds. That's a little slow, sir." He facepalms.

"Holy shit, that's completely normal." Of course it is, but he can't just be cured and walk away. That's not how this works.

"Like I said, Mr. Vantas, it's ok to be embarrassed, I'm just trying to help." He looks like he wants to throttle you. But in a sexy way, you guess. "I'll write you a prescription for "some good ass"." The fucker laughs. You'll admit it's not your best work, but that's just rude.

But yeah, it was really fucking funny.

"Nurses can't prescribe anything, dumbass." He rolls his eyes with a smile on his face.

"Shoosh."

"But if you think it'll work, nurse. I'll take it."

"Good, thank you for cooperating." You straddle his lap and he looks at you, obviously confused.

"Don't you want me to stre-" You put a finger to his lips and he shuts up. You hike the dress up to your waist, exposing your hard on straining against white, lacey panties, a wet spot forming where the head is. Moving the fabric to the side with one hand, you pull out the plug that you were wearing. Karkat moans at the sight. You set it on the bed and position yourself over him. There should be plenty of lube still in you so you angle his dick and slide down, moaning as you seat yourself on his lap. You take a moment to adjust, rocking your hips and making the ginger boy beneath you groan.

His hands come to your hips and grip you roughly, forcing you up and slamming you back down. Your yelp tapers off into a high whine, so he does it again. The third time, you get the gist and start moving on your own, resting your hands on his chest for balance. The way he brings his hips to meet you drives you crazy and soon, you're bringing a hand down to jack yourself off in time with his thrusts. You ride him harder as you feel yourself getting close. He whimpers and matches your pace. One, two, three more thrusts and you're cumming, seeing white and groaning between gritted teeth. He follows close behind, coming inside of you.

One more rope of white splashes on his sweater at the feel of it and you pull off of him and collapse on his chest. He rubs the back of your dress and laughs.

"Please tell me you did not spend more than ten dollars on this thing."

"$37.95." You say and he scoffs. "The panties came free with it though."

"Well, that's good."
