The family party I won't be forgetting In a hurry. Last July as lockdown eased in Scotland I had attended a family get together with my fiancee and kids just along the road to her sisters house. Always enjoy our get togethers as the in laws are a close bunch and I've always enjoyed their company. Drinks were flowing and everyone was in great spirits, and drinking plenty. As the night wore on I and the dancing started I couldn't help noticing how sexy my usual plain Jane looking older sister in law was looking. She is 40 and me 32. In the end my fiancee had enough and went home to bed leaving me to tidy up with Jackie her husband had drank to much spewed and fell asleep drunk outside underneath the gazebo on a sunlounger. Jackie started flirting first saying I got you staring at my legs and bum, I started stuttering an apology when she laughed and said goon night. Be brave and full of drink I cuddle her goodnight and went in to kiss her on the cheek good night when she moved slightly and I got her on the side of the mouth, another stuttering apologie to my surprise and excitement she leaned forward and saying don't tell Raymond kissed us property on the lips. Couldn't believe what was happening but couldn't resist so I responded with another kiss this time I tried to slip a tounge in her mouth. She responded with a slap hard on the face, shit what had I done but I needing had worried as she rubbed my cheek with her hand and whispered ask next time, please I said and tried again this time their was no slap just a hard passionate snog, followed by Jackie saying fuck it he is no use to me tonight, looking out the window at her drunk husband. She grabbed my hand and grabbed me into the back room and snogged me hard this time with her hand down the back of my boxers feeling my arse. My tun I fought as I fi the same up her dress but no underwear just a slight damp vagina. We broke off our hard and very wet kiss and I stayed I was good with my tongue elsewhere if she wanted to find out. With that I was on my knees kissing and caressing all over her now soaking vagina. I loved her scent and taste and after ten minutes or so she was in the verge of Cummin. Disappointed she stopped me was begging to be fucked, my jeans were on the floor in no time as my very thick 7 inches stang free, no BJ she was just wanting me inside her and quick. This wasn't love making but two folk who had growing closer just needing to be fucked. One final kick of her Georgus pussy and I was in, no time to waste for 5 minutes doggy style I was slamming into her with Jackie begging me to come inside her I couldn't hold on any longer, with her vagina clamping down on my cock I pumped what felt like the biggest load of sperm I've ever produced as far inside as I could possibly imagine. Final snog and I was sent home to her wee sisters also my fiancee. Since then I visit most weeks sometimes for a cheeky Snog but on two occasions we have made love to one another exploring each others bodies. Feel guilty most of the time but when we meet up the atmosphere is electric the sex is out of this world.
