Christmas was upon us and we where way behind the normal schedule, presents for the kids where unwrapped at my mothers house and the wife was constantly working overtime in work due to there busy schedule. So sat at home one night my mum suggests me and my sister in law Jane go and wrap the pile of presents we have. "Ok I'll phone her and ask where she is" it turns out she was just around the corner on her way home from work "I'll meet you there" she said so I walked around the corner to my mums house and sat there is Jane she stepped out the car looking rather sexy with knee length bots on and a black skirt that sat just above here knee a black semi see through top with a black bra on. In we went and started wrapping presents I suggested a glass of wine and she readily accepted after a few glasses I suggested we take a break she stood up to go outside for a smoke, as she stood up I could see the lace top of her stockings, I stiffened straight away. She seen me looking and called me a perv, "you love it" I said. "Are you going to show me properly then?" With out a moments hesitation she just hitched her skirt up and showed me her stocking tops and I could just see her pussy through her sheer panties "wow" I said "can I have a taste" to my surprise she said "just a taste" with that she sat down on the couch an just pulled her panties to one side. I moved across to her and slipped my tongue into her, she tipped her head back and let out a little moan as I pushed my face further into her pussy fingering her clit then working it with my tongue l flicked my tongue all over her pussy before sticking a couple of fingers in. I finger fucked her until she came heavily on my tongue. She was very very wet when I stood up and slipped my aching cock into her mouth, she readily accepted it into her mouth and started to lick and suck my bellend which was fantastic . She sucked me until I was about ready to come then she stopped and said "put it in me" I kneeled in front of her and slid my helmet up and down her soaked slit and her engorged clit. She removed her dds out of her bra and started to play with her nipples I moved up and had a little suck and play with them I wanted to put my cock in between them but I thought I'm not passing up the chance of getting my knob in her pussy. I eased my cock into her pussy "stop there" "just the tip in, then just rock backwards and forwards" I have to say her pussy was beautiful I rocked a little then pushed it all the way in before moving back out I kept going just moving the tip in and out which seemed to drive her wild. " I want to cum in you" I announced "ok" she gasped, " cum in me and then over it" "ok" I said. Now this was her sisters favorite sex game and I thought oh well must run in the family. I fired a good amount of spunk up her and deposited the rest over her pussy and flaps just rubbing my bellend up and down her slit as it pulsed more an more spunk over her. "Now clean it" she snapped as she grabbed my head and buried it in her pussy I licked every bit of it clean then moved up to her mouth and spat some come in her mouth which seemed to give her the taste for spunk because she kneeled in front of me and sucked my now recovering cock clean. "Enjoying that" I enquired. "Yes it was fantastic Sarah said this was the best type of sex she's had and she wasn't kidding." She then pushed me onto my back and slid down onto my cock riding me and flexing the muscles in her pussy until we both came again. We sat there for about 10 minutes when my wife walked in "hiya you haven't done much have you" after a few minutes of small talk Jane said " I'll may as well go now" "ok see you later" we said as she was leaving Sarah started rubbing my cock and licking her lips "you know what I want don't you" "let me guess" I said. So off I went again but with the added horny feeling knowing my wife was about to clean her sisters pussy juice of my cock.........what a great day.....I fucking love Christmas.
