Over the last couple of months I have become accustomed to the sight of Seb wandering through the house half naked, but for some reason, on this particular day I paid more attention than usual. Maybe it was the too-small towel barely preserving his modesty, or because I was feeling particularly bored and horny, but something made me take a closer look. I mentally compared his physique to that of my boyfriend Jamie; objectively both men are clearly physically attractive, but in subtly different ways. Seb's cropped blonde hair and sparkling blue eyes attracting a different sort of attention than Jamie's dark curls and soft brown eyes. A few inches taller than Jamie and narrower across the shoulders and chest, his more active job and extra hours working out in the gym clearly show in his sculpted and well-defined muscles. Don't get me wrong, Jamie is in great shape, but the increasing hours stuck behind a desk rather than working out are more apparent when the two of them are half naked together -- a frequent occurrence since Seb has been staying with us, and one that is provoking increasingly disturbing and vivid fantasies in my mind.
In an attempt to distract myself from the cinematic daydream playing in my head I get on with my chores. As I pass the open door to Seb's room I notice the damp towel dropped casually on the floor, and inwardly curse his inability to put his dirty laundry in the basket. Sighing, I pick it up, but as I straighten up a reflection in the mirror catches my eye and I pause to take a closer look. Seeing Seb stretched out naked on the bed, erection in hand, I am entranced by his seemingly flawless form. From his well-muscled shoulders, arms and chest down to his muscular thighs he is model perfect. And his cock - I had always assumed that when the boys joked about his size they were joking or at least exaggerating, but I can't deny the evidence of my own eyes. I am simultaneously turned on and a little scared by the sight; even as I imagine slipping into the room and mounting him I wince in anticipation of the inevitable discomfort of such a large dick filling me so completely. Unable to tear my eyes away from the magnificent sight, I watch as his hand slips up and down his shaft, pausing now and then to caress the tip, sweeping the glistening bead of pre-cum down the thick shaft as lubricant. Too late, I realise that not only can I be seen in the mirror, but also that Seb has opened his eyes and is smiling knowingly as his eyes meet mine, his hand still lazily moving up and down.
Shame at being caught perving at my boyfriend's best friend washes over me, and I slip away to the bathroom to drop the damp towel in the laundry basket and to try to compose myself. Catching sight of my flushed cheeks in the mirror I realise how obviously turned on I am and worry briefly what Jamie might say if he came home and found me so aroused by the sight of his best friend in all his glory. Seeking relief I lean back against the closed bathroom door, slip a hand into my pants, part my slick lips and tease my throbbing clit with my fingers. All I can think of right now is Seb naked on the other side of the wall, magnificent cock in hand, and wonder if he is thinking of me as he continues to pleasure himself. I come quickly, the primal sensations overtaking me so suddenly I don't think to stifle my cry, realising too late that Seb will almost certainly have heard me and know what I have been doing.
Not ready yet to face Seb, I compose myself, grab my handbag and slip out of the house. I have no plan, no destination, just a need to be somewhere else. I love Jamie and our sex life is fantastic, so I am confused and disturbed by the extreme reactions Seb is provoking in me. Walking through the park soothes me, the spring sunlight warming my skin pleasantly. All too soon my thoughts stray back to the scene that played out at the house, imagining the light breeze caressing my skin is Seb's hot breath. I continue to wander aimlessly, and without realizing I find myself standing outside the gym Jamie and Seb run together. Maybe my subconscious has led me here, knowing the best antidote to my racing thoughts is a stolen hour with Jamie.
'Hi! Jamie in his office?' I ask the receptionist.
'Yes, go on up. I think Seb has just gone up too' she replies. Sensing my hesitation, she adds 'I think they are just gossiping -- you won't be interrupting.
Trying to smile I just nod and turn and walk towards the office.
'Hey beautiful! What a surprise, my two favourite people both dropping in unannounced!'
'I thought I would see if you were free for lunch' I say, crossing the room to place a loving kiss on his cheek. 'Do you have time?'
'Sure' Jamie grins. 'You coming too?' he adds, turning to Seb.
Not daring to meet his eyes, I turn to Seb and silently will him to say no. I can't face the prospect of a whole hour trying not to think about what happened earlier, knowing Jamie will sense there is something wrong. Unfortunately Seb's telepathic skills are somewhat lacking, and he grins as he says 'sure! I'm starving!'

'You were quiet at lunch' says Jamie as we make our way back to his office having said goodbye to Seb. 'Something on your mind?'
I hesitate, not sure quite how to respond to such a direct question. 'Seb getting on your nerves? I noticed the two of you weren't as chatty as usual. Has he done something to upset you?'
