An hour had passed since our audience moved on, we had finished our picnic and all went for a swim.
While in the water granma moved over towards me placed her arms around my neck and her legs around my hips. “Mmm I would love you to fuck me in the water like this” she said I then felt something stiff by my ass. “Mmm yeah fuck her while we watch” said grandpa in my ear, it was his cock against my ass. “Lets go over near the rocks first” I said We all swam along the beech to the spot where me and Becky had fucked watching the two guys before. Granma began stroking my cock to full stiffness while I fingered her shaven pussy and sucked on her pierced nipple. Meanwhile grandpa had Mary facing the rocks as he rubbed her holes from behind. No one was around as we played, once I was hard granma jumped up putting her legs around my hips again, “now fuck me and fill me with the juice of your loins” I felt granma’s cunt envelope my shaft and she began to bob up and down water splashing up into our faces as she did so. Grandpa told mary it was her turn for an ass fucking and must have shoved his cock in because mary groaned before even answering him. As granma bounced up and down I was cupping her butt cheeks in my hands, squeezing on them and pulling them gently apart. “Fuck me harder” Mary shouted Grandpa took hold of some of Mary’s hair and pulled on it like the reigns on a horse as he ploughed his cock in and out of Mary’s ass harder. Granma pushed me back a little as she got off my pole, she then turned towards the rocks bent forward and offered me her ass. “Give me what mary is getting please Tim” I moved in behind her and guided my pole to her puckered ass, and pushed in till I was balls deep, then I began to fuck her hard and deep. “Mmm mind if we watch” said a camp voice from behind us Me and grandpa looked back and said sure feel free, but don’t just watch join in. It was the two guys me and becky had seen fucking before, they moved to the side of me and granma and watched us and as they did they both stroked my back and my butt cheeks. “Was it not you we saw here the other day fucking with a beautiful young girl?” one asked “Erm well yes and you two where a little busy too” I replied with a wink. “Hope you enjoyed what you saw because we sure did” he said as he gave my ass a little pinch. I lowered a hand down and made a grab for their cocks, they was both hard and smooth, I switched from one cock to the other. “Hey get one of them cocks over here and fill my ass” said grandpa “There’s your queue honey” said the camp one to his lover. With that he moved around and grandpa took his swollen member and placed it at the entrance to his ass. We could now see grandpa being fucked in the ass while he fucked mary in hers. I continued to stroke the camp guys cock, you not wanna fuck my grandpa?” “Your Grandpa?” I went onto to explain the situation as I stroked his smooth cock, he seemed to get more excited as I told him about our family liason’s.
