"Sherlock, get out, you little shit!"

"What are you doing with him?" The younger boy seemed fascinated, but not alarmed.

"Nothing!" Which, since Sherlock's intrusion, was sadly true. Greg hadn't moved, he was still lying on top of Mycroft with the other boys softening cock between his thighs and his bare arse sticking in the air.

"You should stop eating so many sweets Mycroft, you're getting fat. Are you having sex?"

"No. We are not having sex Sherlock." Mycroft gently but firmly dumped Greg off of him onto the mattress and threw a towel over Greg to cover his now exposed privates. Mycroft swung his legs round and grabbed his bathrobe.

Sherlock span around on Mycroft's desk chair, his legs crossed, frog like onto the seat. Greg suspected Sherlock Interruptus was something that happened quite often to Mycroft.

"Mycroft there's a boy in my biology class. Mr Stanford has made him my partner."

"And?" Mycroft poured his little brother a glass of squash. The boy sniffed it and then took a sip.

"His name is John Watson. He wants to be a surgeon. "

"And?" Mycroft knew there was more to come.

"And he didn't laugh at me when I knew all the answers. He said it was brilliant. And he gave me some of his chocolate. I said I didn't like chocolate but he said that was ridiculous and I should try some. So I did. It was quite nice."

"And what did you conclude from this Sherlock?"

"I don't understand." The small boy frowned and looked at the carpet. Mycroft placed a hand on the side of his brother's angular face and smoothed the dark hair back from his forehead.

"What don't you understand?"

"Why was he being nice to me?"

"He was being friendly Sherlock. That's a good thing."

"Were you being friendly with him just now?"

"That's a different kind of friendly."

"Will John want me to do that with him?" Sherlock looked slightly horrified at the prospect.

"I don't think so." Mycroft shot Greg a look begging him not to laugh.

"I wouldn't mind. He's very nice. He's not an idiot." It seemed all the boy's questions had been answered and he hopped off of the chair, pausing to look at Greg. And then he smiled, his whole face lighting up. "You're very sensible not to allow Mycroft to lie on top of you. He's very heavy. He'd flatten you!"

There was silence for a few moments after Sherlock's exit and Mycroft took the time to lock the door.

"I'm sorry about that. He's...not good with people. He's very bright and he has a tiny attention span and he has to know things the moment he thinks of it. I suppose I'm used to it. But when I see other people's reactions I remember it's not usual."

"Is he autistic? Like Asperger's or something?"

"He's had the tests. He's on the spectrum but not cause for concern. He's just a very clever little boy in a world where little boys aren't supposed to be like that. It's the world that has the problem, not my brother."

"Sorry." Greg took Mycroft's hand and sat him down on his bed. "You are an enigma Mr Holmes. You want everyone to think you aren't interested, that you don't care, but I think you care about everything. "

"He's my brother. I want him to be happy and if that means getting myself into a position where I am able to ensure that then so be it."

"What about you? What makes you happy?"

"My needs are very basic. Now where were we?" Mycroft pushed Greg down onto the mattress.

"Sherlock was right, you are heavy!" But Greg didn't actually mind his imminent flattening. He felt the familiar feeling of Mycroft beginning to push between his thighs and he angled his hips back a little, wrapping his legs around Mycroft's waist . Inviting Mycroft to enter him.

"You'd let me do that?"

"God yes! What's the problem?"

"Greg you need to be prepared."

"I am prepared!"

"No. I mean properly stretched and everything. It hurts. The first time. Well most of the time really. It's a good kind of hurt. But it still hurts. And I don't want to hurt you any more than I need to. Besides, when I take your virginity it's going to be special."

"Okay." But Greg couldn't keep the note of disappointment out of his voice.

"Now, let's try something different."

Greg soon regained his enthusiasm when Mycroft gently guided him into position for what he was proposing. Greg sat on Mycroft's lap, facing away from him, Mycroft's erection pushing between his cheeks so he could slide between them. Mycroft was using one hand to guide himself and his free hand was working on Greg's own needy hardness. They didn't last long. Five minutes perhaps? But to Greg it didn't matter, he turned back to face Mycroft, who's eyes were darker now, the pupils massive, and he put his arms around his neck, pushing him down onto the bed, feeling their completion sticky between them. Greg nuzzled into Mycroft's neck and felt warm arms wrap around him. Mycroft smelled of sweat and musk and sweets and Greg could hear his heartbeat, gradually slowing and his stomach gurgling a little. And very strangely Greg felt safe.

A/N Thanks for the reveiws and likes. My school term starts today so I might not be updating for a bit. MG
