Three christmases ago I went to my sisters in Croydon as my son had gone to his mothers for a week at Christmas and I welcomed the chance of having my meals cooked for me and chance to relax.When I arrived I was surprised to see Joe and Sue(my brother-in-laws parents)who I had met a few times before and got on quite well with especially Sue as she was a former model and still at the age of 55 had great legs which she liked to show off as Joe seemed to be more interested in his hobby of train spotting these days.I sat down and was opposite Sue and was finding it difficult not to look at her legs and she kept on crossing and uncrossing them and liked the attention and I felt myself getting hot and bothered so I excused myself and went upstairs to the toilet to release my hard cock from the strains of my trousers and gave it a good hard wank and after about 5 minutes shot my hot spunk into the toilet bowl did my trousers up and splashed my face with cold water before going downstairs.My sister Karen told us to sit at the dining table and Sue ended up sitting close to me as the table wasn't very big and it was a tight squeeze and when the plates of food came Sue squeezed my left leg and my cutlery fell on the floor so I got on all fours to pick them up and saw what Sue had between her legs which was a trimmed bush and I eneded up banging my head on the table and everyone laughed unaware what I had just seen.The evening went by quickly mainly becuase everyone was drinking a lot and some nodded off so I went out into the back garden to get some fresh air and about 5 minutes later Sue came out and sat alongside me and asked if I liked what I saw and I said yes it looked nice all trimmed and as she ran her hand up my leg I could see her nipples were rock hard.I told Sue that it was a shame I didn't have a room to sleep in as she could of sneaked into mineduring the night and she leaned across and kissed me and went back inside. My sister suggested we all went to bed as my niece would be up early on Christmas day so one by one everyone went upsatirs until it was just me and I made my temp bed on the sofa and lay there finding it hard to get to sleep but I must of dozed off as I felt soemone shaking me and quitely saying my name and when I opened my eyes it was Sue sitting at my side in a dressing gown and when I fully opened my eyes she stood up and dropped it to show me her naked body and I felt my cock slip through the gap in my boxers and Sue went straight to it and started to wank me off with one hand and rubbing/squeezing my ballbag with the other and causing me to lift my body off the sofa she then leant forward and put her lips to my helmet and spat some spit on to it then took it into her mouth and was soon into a good sucking motion and I was pushing her head down so she had all of my cock inside her warm mouth and I told her the first time I saw her I wanted her to do that and she quickened up and I told her I was going to shoot and I pressed her head down and I shot my spunk into her mouth and I told her to swallow it as I didn't want to stain the sofa and Sue didn't argue and made sure she didn't let any dribble out of her mouth and carried on licking my cock and balls clean of spunk and eventually released my cock and looked me in the eye and said she hadn't even sucked Joe off before but had sucked a few men she had met off of the net.I told her that I wanted to fuck her and she said not now and kissed me on the cheek and grabbed her gown and went upstairs.The next day Sue and Joe had to leave as Joe was feeling poorly so there went my chance to fuck Sue but my sister rang last week to say she wanted to know if I fancied spending christmas there this year and I asked who was going and she said my brother-in-laws parents would be staying so I immediately said yes.I wish it was December now as this time I will be staying in a bedroom right at the top of their new house and it is cut off from everyone else.
