Stuart meanwhile is coming in from the rear, and has wrestled me out of my jeans and shoes so that I am naked while he and Matt are clothed. Obviously this appeals to my sense of vanity, and we go with the flow for a while, and before I know it Stuart is sticking a load of lube up my arse and is about to fuck me. Matt is slobbering over my chest, and my nipples are actually getting quite sore now.

Stuart manoeuvres me into a kneeling position and slides his cock into me; I haven’t even checked whether he’s got a condom on. He’s taking a big hit from a bottle of poppers which he then sticks under my nose, and I inhale. There’s a huge rush as he starts fucking me, and then Matt gets back on to my tits like a pig returning to the trough, and we carry on like this for a while, banging away. The neighbours must be furious, I think, and that’s when I know that the drugs are really wearing off and I’m actually not enjoying this at all.

Somehow the entire show has now moved to the bedroom – I don’t remember getting here – and now it’s Matt who’s getting fucked while burying his face in my chest. I’m feeling like garnish. Stuart’s eyes are half closed, only the whites visible, and he looks more than usually mask-like. He’s been banging away for what seems like an hour, and shows no signs of finishing. Occasionally he slaps Matt’s arse, or grunts out some obscene monosyllable.

Suddenly I’m revolted by the whole scenario, I want these people out of my house, out of my bed. I push Matt’s face away from my chest and extricate myself from the various limbs.

Stuart’s eyes flash open.

‘Where you going?’

‘I’ve had enough. I’d like to be alone.’

‘Go on, then. Suit yourself.’

Matt is so out of it that he doesn’t seem to notice I’ve gone, and carries on licking the air where my tits were. Stuart keeps mechanically fucking him.

‘No,’ I say. ‘I mean, I think you should leave.’

‘Fuck off,’ says Stuart, and that’s it. His eyelids come down like shutters, he grips Matt’s hips and carries on pumping.

I go to the living room, and lie on the sofa. I don’t have a spare duvet or a sleeping bag, so when I start feeling cold I pull the rug up off the floor and wrap myself in that. I can hear Stuart and Matt at it in the bedroom, I can hear the downstairs neighbours crashing around and shouting into their mobile phones, and as I drift into sleep I can hear voices and music in my head, as if I’m still in the club.

I get up for a piss around first light, and peep through the door into the bedroom. Matt is fast asleep in Stuart’s arms. They look very peaceful and happy. I feel as if someone has stuck a butcher’s knife in my stomach and is twisting it.
