Shocked By Size Of Grandson’s Cock

Now the day after my daughter’s silver wedding anniversary party I have been left on my own looking after my youngest grandson while his parents have a few days away. The youngest of three at eighteen and not with the best of health since birth, he is also intellectually challenged with an age of a six year old and very clingy to his mom. It is best to ignore what he is doing wrong because he will do it even more. His latest habit is playing with himself in the shower in front of his mom. Since being small my daughter has showered with him and now this ritually cannot be broken. I have to come to terms that I am going to be naked in front of him and act that it is all normal. He looks forward to his playtime in the shower before bed and that is where we are now, in the bathroom helping him undress. I knew he was weak and skinny by looking at him but was shocked to see that he is hung like a horse; hanging soft, he must be 8 inches and as thick as my wrist. He giggles as I start to undress in front of him and now standing only in my bra and knickers, I see his dick hardening. Widowed for ten years and in my sixties I never thought I would see another cock again; never mind having to take a shower naked with it. I’m nothing like his mom; she is skinny with running after him all the time, where I am well developed up top, well nearly hanging down to my waist now as I pull my bra from under them. It feels weird slipping my knickers down my legs and being watched and all the time ...

... his cock is rising upwards. “Mom’s all smooth,” he says pointing at my big hairy fanny that I have and laugh’s. “In the shower Sam” I say trying to change the subject I’ve been told just to take our time and he will wash himself in a fashion, then he will want to wash me too, but just to let him. I watch him soaping his cock that is sticking straight out in front of him, slipping his hand back and forth and making it even bigger. My eyes nearly pop out of my head looking at the size of it as he plays with himself and unable to tell him to stop. He starts to pant and scream, as his hand gets faster and faster on his manhood. Shit he has came with a mighty squirt of cum, spraying me on my fanny and right up my tummy. Sam laughs and pumps another load out then another and another, he lifts his hand up eventually and we watch as his cum drips from his fingers. “Wash, wash,” he shouts out I cannot believe this but here I am washing my grandsons cum from his fingers, then I wash him properly but still unsure about washing his cock. I sink on to my knees and wash his legs, his cock only inches away from my face hanging semi hard but still as big. I eventually move on to his cock, my first touch of cock in ten years and it feels nice. He starts on me after I finish washing him and he finds my tits very interesting to play with and wobbly. I cannot suppress the hardening of my nipples and they are the bits he is most interested in playing with. Hopefully he might get board before long ...
