"Ok then. On this night Claire was wearing this huge ankle-length pleated skirt. I mean so much fabric, you could have run it up a mast and gone sailing with it," I laughed. "We were talking and talking, drinking and drinking, and got kind of wrapped up in each other's company. I hardly talked to anyone else, even Bill. As the night wore on we were getting more and more flirty with each other, leaning in close to talk over the noise in the pub. We barely noticed that the rest of our party had started to drift off. Eventually, Bill said goodnight and we realised it was just us left at the table."
Susie was listening intently. She put one foot up on the sofa which made her dressing gown fall away from her right leg slightly, showing off her thigh as it curved towards her ass. My eyes flicked momentarily to take in the newly exposed skin and my words caught for a second. I knew Susie had noticed this, and I detected an almost imperceptible glitter in her eye. She did nothing to re-adjust her garments. "So what happened when you were finally alone with Claire, Martin?" she asked.
"Well we kept on talking," I replied. "But things definitely turned up a notch. I pulled my stool in close to her so our knees interlocked a little and I got hold of her dress and sort of spread that fabric over both of us so my legs and hers were both underneath. That's when she leaned in and kissed me, which really got things moving. I moved my hands under the dress. Her legs were bare, slim and so smooth. We then spent the next little while kissing while I caressed her thighs. I had the biggest boner, but because Claire's dress was pulled over my lap, no one else could see."
Susie put her other foot on the sofa at that point and her dressing gown fell away from her other leg too. Her knees were together and leaning over to one side revealing about two-thirds of her ass cheeks from where I sat at the other end of the couch. I took a longer look than I intended this time and when I looked back into Susie's eyes she was staring right at me. "I really need you to tell me what happened next, Martin."
I was beginning to feel my own loins tingling, both as I relived that night with Claire and also because of the view I had of Susie's ass right now. It looked to me like she was wearing nothing at all under her dressing gown. My heart kicked up a gear and I could feel myself stiffening, but I tried to play it cool and continue with my story.
"Well before too long," I said, "my fingers were brushing against her panties right up between her legs. She was soaking wet and so turned on. It felt like my boner was going to pop the buttons right off my pants. We started talking dirty as I hooked my fingers inside her panties and slipped my fingers inside her pussy. Her eyes were rolling back and she was moaning quietly. I asked her if she liked it and she said yes. Do you want me to fuck you baby? Yes she said. I'm going to fuck you right here in front of everyone, I said to her with my fingers inside her and her juices all over my hand."
Susie had put her glass down and had her hand in her lap. "Did you make her cum in the pub in front of everyone, Martin?" asked Susie. I got the distinct impression she wanted the answer to be 'yes'.
"No I didn't. That would have been a bit too much exhibitionism. But Claire did at that point put her hand on my crotch for the first time and felt how fucking hard I was. Her eye literally bugged out with some mix of surprise and extreme lust. I mean, I'm not a small guy..."
"I've heard," said Susie cutting me off. "Sam says you're hung like a horse." Her eyes dropped to my lap where it was impossible for me to hide the ridge in my shorts running halfway to my left knee. "I can imagine how much she was longing for that massive cock to pound her and fill her little snatch with cum."
I was a little surprised by Susie's dirty language, but I nodded my agreement. "She was on fire. After she felt my erection she stood up and literally dragged me out of the pub and up the street. It was dark outside but the street lights were bright. She pulled me into that park near the uni, you know the one? Which turned out to be perfect. We found a nice dark corner and she pulled me down onto the grass, tearing at my jeans. She was in a total cock frenzy and couldn't get it into her mouth fast enough. Man, I've never been ravaged like that, it was kind of awesome, thinning about it now.
"When she was done with sucking me off she tore off her soaked panties and just threw them away into the dark. She climbed right on with that dress covering us both and rode me like a fucking pony. And she was screaming so loud I was sure as hell the police we going to come and arrest us."
"Well I no longer feel like such a slut," she said when I finished, smiling. "But I have to admit that was pretty hot. And I noticed you quite enjoyed reliving the experience," she said looking down at my still bulging shorts. "Might need to do something about that before you go to sleep," she winked. "Can I watch?"
"Susie!" I said putting my hand across the bulge.
"Only joking," she said. "Kinda."
It was pretty hard to figure Susie out sometimes. She was sure easy to talk with, even though it felt like we'd been a bit edgy this time, crossing some lines that weren't meant to be crossed.
"Time to get your bed sorted out I think," she said and swung her feet to the floor, sitting up. I caught a flash as she did this, a split second view all the way up between her legs. She was most definitely not wearing panties under that gown. She stood up and straightened her clothing in a way that drew my attention to the soft mounds of her breasts before she walked towards the hallway, hips rolling seductively. This did nothing at all to diminish my hard-on. "Come on," she said, "I'll need your help for this. There's a box in the cupboard and the shelf's a bit high for me."
I stood up and followed her down the hall, hyperconscious of my boner while looking at Susie's ass move in that gown, no panties underneath. I breathed deeply and tried quite unsuccessfully to put all of that out of my mind.
She opened a normal looking door in the hallway to reveal a cupboard with coats and a shelf up above the rail. She stepped in among the coats. "It's that one," she said, raising herself on tiptoes and pointing to a large plastic storage box on the shelf. I entered the cupboard behind her, and reached up over her head to get hold of the box. I pulled the box towards me with my fingertips. I was pretty heavy and didn't move easily, but I got my hands either side and inched it a bit further so it overhung the edge of the shelf. One more movement should do it, I thought, and I inched the box further until I could feel the weight pivoting on the corner of the shelf. At that point Susie, who was still infront of me in the cupboard, moved slightly backwards, her ass making direct contact with my stiffness.
"I'm so sorry," she said. But instead of recoiling, as she would have if she'd bumped me accidentally, she started moving her ass until my prick nestled between her cheeks. I couldn't really move as I was still stretched up, holding the box that was teetering on the edge of the shelf. Susie reached back and held my hips on both sides, docking herself more firmly, grinding against my rod.
"Don't be sorry," I replied, managing to push the box back into place. "It's just biology," and I slipped my hand around her waist, inside her dressing gown and across her smooth soft tummy, pulling her against me. We stood there for a minute breathing hard, realising that we had well and truly crossed a line that we'd never be able to retreat to.
No sense in stopping now, I thought, and undid the sash on her gown. I moved my hands upward over her torso, taking hold of her succulent breasts. She was much bigger than Sam and I'd admired her tits at numerous family gatherings. It was quite a thrill to actually get a hold of them. Her nipples were very hard and I squeezed them firmly. "Oh, Martin," she said. "What are we doing."
Susie reached back, and started pulling at my shorts. I helped her out, undoing my top button and zipper. She slid the shorts off easily after that, and then reached inside my underpants to grasp my iron shaft with one hand, pulling the underwear down with the other. It was my turn to moan now as she stroked me behind her back. "Mmmmm," she said, feeling my full length. It seemed fitting that we weren't looking each other in the eye for this. My hands moved back to her hips, circling round to the front of her thighs, then moving towards her centre. I passed a hand over her shaven mound, index finger sliding between her labia, tracing the outer shape of her pussy. She was very wet, and her breath became quick and shallow as I massaged her delicately. Tom was in the next room, hopefully asleep, and we needed to be as silent as possible.
"Fuck me now Martin," said Susie, panting a little as my forefingers rubbed her clit. She reached up, grabbing the coat rail above her head as she pushed her ass outwards and towards me. I put my cock between her legs and let my tip run through the sopping trench of her cunt, making her moan. I moved myself back and forth a few times, my shaft slick with her wetness. "Please," she breathed. I positioned myself at her soft entrance, head engaged, and pushed myself two inches into her. "Ohhh," the sound came out of her involuntarily.
"We need to stay quite Susie," I said, and put my hand over her mouth as I thrust my full length into her. She gasped into my hand, and then, slowly at first, I began to move in her. I wanted her to feel my full length sliding in and out, filling then emptying her as she clung to the coat rail. On the in-stroke I grinded myself against her, crouching slightly so I could push my hips up and forward to get as far into her pussy as possible. Her cries became muffled as she bit down on a coat sleeve. Soon, her legs began to quiver and I reached around with one hand to massage her clit as I continued my deep thrusts. She let out a low guttural sounds, and her body shuddered with the orgasm that arrived. A few moments later I could feel the tingle in my balls and asshole that told me my own was imminent.
So there I was, shooting semen into my wife's sister from behind, inside her coat cupboard, cock buried to the hilt, with her partner asleep in the next room. It felt so completely right. Am I a bad man? I thought. I had no answer in that moment. We stood there for a few more minutes in the aftermath of our orgasms, my cock gradually softening inside Susie's pussy, my sperm beginning to drip onto the shoes at the bottom of the cupboard.
