The sight that greeted me as I unlocked my front door and stepped into my front room was my sister in-law's arse, clad only in loose fitting pink night shorts, as she knelt in the corner of the room, rummaging through mine and my wife Rachel's DVD collection. She turned abruptly, obviously shocked and instantly blushing. 'Adam! Oh!' She exclaimed. 'I err... Rachel said you wouldn't be back until later.'
'Jenny, hey! Sorry, I didn't mean to scare you, the guys were heading into town and I couldn't be bothered to join them, so I just came straight home from the pub. What are you looking for down there?' Jenny had stood to her feet, turning to face me in the process. I couldn't help but notice she'd gotten dressed in her nightclothes and, in the process, removed her bra. Her nipples poked stiffly through the flimsy material of her nightshirt and her gargantuan breasts swayed freely as she turned. I fought to prevent a stiffening in my crotch, reminding myself that she was my sister in-law. Hell, we'd known each other so long; she might as well have been my real sister.
'Rachel went to bed early.' She answered, dodging the question. 'We've both had a few drinks and I think it hit her more than me. I went for a shower, came back down and she'd gone to bed. I was going to have a couple more drinks.' She motioned to the drink on the floor next to the sofa. 'I completely forgot you were coming home. Sorry.' I noticed she was slurring a few of her words, suggesting she was already on her way to getting drunk herself. I had known she was coming round tonight, her and Rachel had planned to go out for a run, and then have a few drinks. I figured Rachel had burned out early.
'I'll go check on Rach,' I said, 'then do you mind if I join you for a drink?'
'Sure, sure...' she replied, her pause told me she wanted to say something else.
'What's up?' I asked.
'Do you, umm... have any weed?' she managed to ask, before blurting out 'I've just been really, really fancying some all evening and Rachel said you had some, but I know she doesn't like smoking it, so I figured I wasn't going to have any, but now you've come in and...'
'Sure,' I laughed, 'wait right here.'
Ten minutes later we were sat on the sofa, watching some Spaced on DVD, I had rolled a nice fat joint and we were drinking some vodka. Rachel had indeed been passed out in bed, naked and on top of the sheets. I was almost tempted to just forget about Jenny and wake my slumbering woman up, but by the sounds of those snores I didn't think I could wake her if I tried.
'So anyway,' I said as I passed her the joint, 'you never told me what you were looking for when I came in. You looked like a rabbit caught in the headlights of a car when I came in the house; like I'd caught you stealing or something.' Jenny visibly blushed as I spoke to her, dragging deep on the joint to avoid answering. 'Tell me...' I prompted, giggling.
'...' She looked so embarrassed, and, I have to admit, hot, as she squirmed in her seat. Her and Rachel looked quite similar facially, big eyes and cute little button noses, but it was the figure where they differed. Rachel had always been tall and athletic looking, with perky little B-cup tits and long, slender legs. Jenny was more glamour model-esque. A bit shorter, but fuller in figure, with huge, swaying tits and rounded, hourglass hips. That big old arse of hers firm and very fuckable. I had always fought against lustful feelings for her, being that I was married to her sister, but I must admit, sometimes my imagination ran away with me.
'Come on,' I prompted once again.
'Rachel had gone to bed and I wanted to watch a DVD.' She finally blurted out.
'That's it?'
'Well yeah, but you know, not just any DVD... I was looking in your collection to see if I could find any, you know, adult DVDs.'
'You mean like porn?' I said, laughing at her embarrassment.
'After a few drinks, I get... you know, urges.' She took a deep swig from her drink and flopped back on the sofa, the drink and weed clearly getting her as she became less inhibited about what she was saying. 'My God, I can't believe I just admitted that,' she said, then burst out giggling. Her nipples looked like they were about to burst out of the top she wore. I had to readjust myself to hide my now throbbing erection. We sat in silence for a while, drinking, smoking and watching the TV screen. Well, I pretended to watch the TV. In my head I was playing a fantasy where I'd arrived home just 10 minutes later and caught Jenny sat on my sofa, finger fucking her sweet little pussy.
Jenny snapped me out of my fantasy. 'It looks like I'm not the only one to have urges!' She said before bursting into a fit of giggles. Snapping my head down, I saw my throbbing tent-pole, bursting at the fabric of my jeans, almost twitching in my lap. Now it was my turn to be embarrassed as I grabbed a cushion in a vain attempt to hide myself from her. To add to my embarrassment, Jenny, without missing a beat, swung her feet up and plonked them onto the cushion, my throbbing erection straining at the touch. 'Relax,' she slurred; the effects of weed and booze clearly visible now on her flushed face. 'Besides, you've had a good few looks at my nipples so far, you naughty boy. Don't you know i'm basically your sister?'
