I continued fucking Billy at least twice a week but I started to notice subtle changes. The first thing I noticed was that, when we met up with Billy on a saturday night, I no longer felt a sense of subdued animosity coming from Mike and, even though that made things a little easier, it irritated me. If I'm honest, and I'm trying to be, I got a little extra thrill from knowing that what I was doing was making Mike jealous or even slightly angry, it made me feel naughty, no wicked.
The next change was that Mike and Billy started greeting each other like they were old friends instead of just two guys that only knew each other because they were both fucking me. At first, I found that funny but, after a while, it started annoying me as we sat in a pub and they chattered away, usually about music, and I was more or less ignored.
I suppose that, in a way, that was my fault because I didn't really want to get to know Billy ( I was far more interested in what was in between is legs than what was in between his ears ). Of course, we did talk in bed, whilst catching our breath, but usually it was about how he loved my tits or what position we should try next, anything else just went in one ear and out the other.
Back at the house, they'd pick up their conversation where it had left off and I often found myself serving them drinks and snacks like a good little maid until I told them enough was enough and it was time for Billy to take me upstairs.
It all came to a head one evening when I went upstairs, stripped naked and sprawled out on top of the bed waiting for Billy to arrive and when, after nearly twenty minute, he still hadn't turned up, I put on my dressing gown and went downstairs. I could hear them laughing before I even reached the foot of the stairs and they were so engrossed in their conversation that they didn't even notice me enter the room until I stood between them.
I was furious and I demanded to know what was going on. Neither of them answered but Billy leapt to his feet and followed me as I turned on my heel and headed out of the door. He scampered up the stairs behind me, apologising with every step but I just ignored him as I shrugged off my dressing gown and threw myself onto the bed. I snarled at Billy "Ok, fuck me, that's what you're here for" and I watched as he frantically tore off his clothes.
I was determined to remain angry with him but it's hard to stay mad with someone who has his mouth clamped over your cunt and is making you scream so I forgave him and allowed him to spend the rest of the night attempting to placate me with quite a lot of success and, after that confrontation, Billy never dawdled when I said it was time to go upstairs.
It was maybe a couple of weeks later when we returned home with Mike definitely a bit worse for wear and no sooner had I handed him a pint of beer than he was fast asleep. I quickly took the glass from his hand and gave him a gentle shake but he was totally out of it and even started to snore.
I felt that this was an opportunity too good to miss so I sat down close to Billy on the sofa with our hips pressed against each other's and, keeping one eye on Mike, I reached down and placed my hand on the bulge in Billy's jeans. I was pleased to find that he was already hard and his prick twitched beneath my palm so I carefully moulded the denim of his jeans to the shape of his cock and wrapped my hand around it as far as the material would allow.
I glanced back at Mike but he hadn't moved or reacted in any way so I began sliding my hand up and down Billy's shaft, swirling my fingertips at both ends on his balls and bobby's helmet. Billy heaved a sigh and reached over to open a couple of buttons on my blouse so that he could slip his hand inside, scoop my nearest breast out of its cup and pinch its stiff nipple between his thumb and forefinger.
It was my turn to gasp and I briefly closed my eyes but quickly reopened them when I remembered that Mike was sitting not six feet away from us. Mike was still gently snoring and a slight gasp of disappointment escaped my lips as Billy's hand left my nipple but I gasped again in excitement as is hand found the opening in my wrap around skirt and he placed it on my stocking clad thigh just above my knee.
His fingers drew teasing circles on my thigh, slowly advancing inch by inch as my breath caught in my throat and, once again my eyes closed. He reached the bare flesh at the top of my stocking and his fingers traced the strap of my suspender until they reached the leg of my black satin knickers.
I was breathing hard as his fingertips roamed over the silky fabric of my knickers as if he was trying to gauge the size of them before his index finger swept along the length of my cunt causing me to jump and gasp out loud.
The sound of my cry startled me and my eyes flew open but Mike was just as I'd last seen him. Billy's fingers crept under the elastic of my knickers, burrowed through my pubic hair and three of his fingers slipped into my sopping wet cunt. I was so wet that I was making sloshing noises as his fingers darted in and out of my hole at a breakneck pace and I tried to stifle my moans as I frantically tugged at his belt and zip.
I glanced towards Mike once more as dragged Billy's hot, hard prick from his jeans and I was shaking with excitement because I was going to straddle Billy's dick and fuck him right in front of my husband.
Billy's fingers were working magic and I knew that I was about to cum so I gasped "No" and pushed his hand away as I manoeuvred his prick into a vertical position ready for me to pounce on it and impale myself on it when Mike suddenly grunted and jerked into an upright position.
I leapt to my feet and my skirt and blouse fell back into place as I hurried over to Mike and said "Come on, you need to go up to bed or you'll get a stiff neck" but I could tell by the vacant look in his eyes that he wasn't seeing or hearing me and, instead of getting to his feet, he laid his head on the arm of his chair and went straight back to sleep.
I was flushed and panting for breath but my excitement had fled and, even though Billy was still sitting there with his prick standing to attention, the urge to fuck him in front of Mike had vanished so I just nodded my head towards the door and we both went up to bed.
I knew that Mike still regularly lurked on the landing outside our bedroom door listening to me and Billy fucking and that thought only served to intensify the power of my orgasms and I knew that Mike regularly masturbated as he listened because I often discovered little puddles of spunk on the landing carpet or streaked down the bedroom door. Of course, I knew that he wanted to watch me fucking and I suppose that I took a maliscious pleasure in not letting him and I sometimes cried out louder than necessary when I knew that he was listening just to torment him.
