Some days later I realised John had been sounding Jan out about mixing it with mum because we started planning an ambush on mum and in a few days we would meet and go to my house. The day came and the four of us arrived at my house and mum offered to make dinner for us all. We arrived and did the usual chit chat before dinner with a few drinks. Mum served dinner, which was great, and because I knew what was going to happen, my cock was hugely rigid so I pulled Lin’s hand over so she could feel it. She was trying to unobtrusively stroke me up and down but I saw that mum had noticed and her eyes were riveted on Lin’s arm and she seemed to be squirming on her chair. We had finished dinner and mum said “what would you all like for desert?” John was behind her by then and leaned over her shoulder sliding his hands down into the front of her blouse to cup her full breasts and he said “we want you”. “What?” she said, and Jan said “we are going to shag and lick you till you cum so much that you’ll be exhausted”. With that, Jan undid mum’s skirt and slipped it off with her panties then pushed mum’s legs apart and dove onto her pussy. John had his cock out and slipped it into mum’s mouth. Lin and I pulled mum’s blouse and bra off and we each sucked on a tit. I was watching Jan’s arse and decided that it was time to sink my cock into something juicy, so I knelt down behind Jan and slid my cock into her pussy shagging her hard until I felt the familiar surges of my cum so I said “mind out I’m cumming” so Jan moved over and I slid my cock into mum just in time to shoot my load deep inside her. Just then John grunted “I’m cumming now” so I moved over and he slid into mum and groaned through his orgasm which made mum have her first orgasm.
Lin knelt in-between mum’s legs and started to lick up all the cum that had started seeping out of mum’s pussy, my cock was still hard so I slid it up into Lin’s pussy and started to slowly shag her. Mum laid down on the floor and John dived on top ramming his cock deep inside her. The two girls moved to mum’s nipples and I thought I was getting close again so I moved my cock to mum’s mouth and I shagged her mouth until I shot a load down her throat. A short time later while I still had my semi hard cock in mum’s mouth being sucked dry John shot his load into her and when he pulled his cock out Jan sucked it dry and then licked mum’s pussy dry of his cum, continuing until mum had another orgasm (her fifth in about 20 minutes). John and I needed a break for our cocks to revive so we all took a break, except mum who I sat on my knee with her feet up on the table while I slipped my fingers of one hand in and out of her pussy and massaged her clit with the other and the two girls and John took turns sucking her nipples. After ten minutes of this mum came again and despite, or because of, mum being on my knee my cock was starting to revive and reared itself up between her legs. I eased mum forwards so she lifted up and my cock slipped into her, she was definitely enjoying herself as her pussy was dripping wet. Mum then told the girls to lie down so she could service them whilst I shagged her from behind. So they laid side by side with their hips touching and lifted their legs up so mum had easy access and started to lick out both girls in turn.
