Asexual, bedhopping!Sherlock

[triceybabe.livejournal.com]

The story I'm looking for is a university au. Greg and John had just met while moving into their new residence. Sherlock and Mycroft came a few mins later. The boys get pretty close to the point that Sherlock has no problem sleeping with either. I remember a scene where they go on holiday and have to share a king size bed together. And that's all I'm going to say about that. Don't want to give away too many spoilers! Lol its a great story. Please help. Thank you!
