Okay this story has been pretty shitty. Apologies. But I've started now, I should finish it.
Sherlock falls back in to his bed pulling me down on top of him, our lips never breaking contact. I bite his neck, and he lets out a moan. I have never been so painfully hard in my life. Sherlock moves one hand to cup the back of my neck, while the other hand snakes between us, palming my hardened cock through the denim of my jeans. I make a strangled noise, and hastily unbutton first mine, then Sherlock's shirt. Our chests are pressed together, and the feeling of skin on skin is so amazing that it makes me even more desperate to touch every part of him. As he shrugs off his shirt I fumble with the button of his trousers and finally tug them down, and he sighs with relief as he is freed from their restraint. He has stopped rubbing my erection to remove my jeans also, and soon our pelvises are moving against each other, separated only by the thin fabric of my boxers and his briefs.
I never want this to end, but I'm a seventeen year old boy, for god's sake, and I can't last much longer. The front of my boxers are moist from precum, and I can tell from Sherlock's, hard, ragged breathing that he's close too. I roll us over so that he is on all fours above me, pulling down the waistband of my boxers, while at the same time Sherlock pulls his erection out of his briefs. Our dicks touch and the friction makes me gasp. Sherlock releases the sexiest, shakiest moan I have ever heard.
As I dig my fngers into Sherlock's back, he wraps one of his long hands around both of our cocks, while the other tugs at my hair. I cry out in increasing volume with every pump of his hand, the movement made easy by sweat and precum. He is grunting curse words, and it's animalistic and sexual. The tightness in my groin mounts, until finally, and dizzily, I come, throwing my head back and shouting his name as I explode violently with sensation. Sherlock follows. His orgasm is not loud, but is intense, much like his personality. His eyes roll back and he bites his lip, letting out a final, satisfied grunt.
I let out broken moans of pain mixed with pleasure as Sherlock continues the movement of his hand, but softer now, slowly bringing us down from climax.
