"Well, I'm going to head up to bed; goodnight you three."
I smiled and returned Erica's wave as she stood up from beside her sister and headed for the door to the stairs. I was locked in another game of pool with Alice's new boyfriend (of about 3 months), Aaron, and as our daughter had struggled sleeping the first couple of nights, she was already asleep in our bed, so there'd be no sex tonight anyway. A little longer up with Alice and Aaron wouldn't hurt.
It had been a nice few days away in the lakes, a family trip for Erica's dad's 60th birthday, with our little family, Alice and her boyfriend, their brother Alan and his girlfriend Mandy, and Erica's parents, of course. We'd done all the standard Lake District things - boat trips, fell walking, even visited the Pencil Museum - and it had been a really lovely time away, with a few drinks among us each night, of course.
Despite being the last night, with a long drive home the next day, tonight was no different, with the booze flowing throughout the evening. Erica's parents had gone up to bed first, not including the children of course, followed by Alan and Mandy, who had disappeared through the kitchen to the downstairs bedroom adjacent tot he living area. There had been a brief few minutes of embarrassment soon after, as we all heard what certainly appeared to be the hammering of a headboard against a wall about ten minutes after they'd disappeared. Alice, easily the more inebriated of the four of us left, had giggled furiously and whispered, blushing, to Erica while Aaron and I had chosen that time to move to the pool table.
Erica left the room, blowing me a kiss as she left, and Aaron took another shot, narrowly missing the pocket, before turning to meet Alice, who had stood and crossed the room as her older sister left.
As I leaned forward to line up my own shot, I let my eyes linger appreciatively on my approaching sister-in-law. She was in a tartan set of pajamas, cotton shorts just long enough to be decent around family, and a button up top of the same material.
Aaron had his back to me, and I made no effort to hide my appreciation of Alice's bare legs, with only a pair of red, fluffy socks below her pretty thighs, from Alice herself - we've fucked enough times now for her to know I think she's hot! As she hugged Aaron, she acknowledged my perusal with a cheeky wink and by sticking her tongue at me, before she turned her head and planted a big kiss on Aaron's cheek. Her left hand disappeared from around her boyfriend's neck and, judging by the way he jumped a second later, reappeared by grabbing his cock!
Aaron, a few drinks gone, very quickly seemed to have lost track of where he was and who was around, as both hands grabbed Alice's arse, lifting her up, her legs wrapping around his waist, as their lips locked and their tongues quite clearly began to wrestle.
I chose this moment to re-introduce the pair to reality, firing the white ball into a small group of others. Aaron visibly jumped and dropped Alice, her feet touching down as she broke the kiss and grinned cheekily at me. Aaron visibly blushed as he turned, looking extremely bashful as he surreptitiously brushed his erection to one side in an attempt to hide it (we've all done it, and I'm good at noticing these things by now!).
"Think I'll head up myself," I grinned. "Might be worth you two doing the same." I chuckled knowingly as I said this, but Alice was already shaking her head.
"Don't be daft," she replied. "You two finish. In fact, I'll play - help you speed it up." She grabbed the cue from where Aaron had leaned it as she'd walked over, grabbed the white ball (immediately messing up the game of course, but she had other ideas, I think!), plonked it down where she wanted it, and rather obviously stood right in front of her boyfriend and bend over to make her shot. It was a little hard to tell, from my angle, just how much she was pressing her arse up against his erection, but from the look on his face it was enough to turn him on some more.
A wild shot was followed by a long kiss for Aaron, whose blood had clearly left his brain at this point as he made no effort to hide the erection in his sweatpants as Alice's tongue again wrestled his own.
What Aaron couldn't see, his own eyes closed, was that Alice's were wide open, giving me a look which over the past few years, I had come to recognise meant, "I'm horny as fuck," and usually ended with her screaming on the end of my cock, normally with her sister watching on. The familiar expression on her face had its usual impact, and I felt my own blood redirecting and my cock start to stir. I wondered how she planned to work this - we hadn't had sex since she had gotten together with Aaron and as far as I was aware, he hadn't been made aware of our little family "understanding."
As if in answer, she broke the kiss, stepping away from her breathless boyfriend, and grabbed the pool cue again. The balls, unnoticed, had again come to a stop while I watched her making out with the younger man. Alice strode purposefully round the table, cue in hand, grabbed the white ball to position again, and stopped in front of me, placing the ball.
Even knowing what was coming, it almost seemed to happen in slow motion, as I waited for Aaron's reaction. Alice stepped backwards, pressing her pert arse against my quickly growing crotch, and then leaned forwards, slowly, sensually rubbing her butt cheeks against me as she did so. My semi-erection lay nestled between her arse cheeks as she peered up very deliberately at her boyfriend.
As Aaron drunkenly took in what was happening, I decided - exercising a little caution, at least - to offer the pair an "out" before it went one way or the other. I leaned forward over Alice, who moaned slightly at the feel of my erection hard between her arse cheeks, and, adjusting her hands at both ends of the cue, lined up a pot. The red ball rolled gently into the pocket and the white slowly came to a stop before I stood back up behind Alice, who I don't think had broken her eye contact with her boyfriend once.
I stayed in position for a few seconds before I stood back up, not making any particular effort to remove my cock from between Alice's cheeks. Aaron stood dumbly for a few seconds, Alice still in position looking up at him, before he took a long drink, finishing his three-quarter full glass of vodka and coke in one.
"I think," he said, stepping forward, "That means you get another go." He rolled the white ball back to Alice, who caught it and placed it again.
Aaron's eyes left Alice's at last and found mine. "I think she needs your help again."
I smiled. This was going to be an exciting night after all.
