Grandpa is having incest sex with his granddaughter

«after mom was passed away i was so lonely, sex had been a big part of our life, i got some things to help, a vibrating vagina and blow up doll, my family came for Christmas, son, D.I.L and granddaughter, we had a great three days, granddaughter asked if she could stay with me until the new year, we were having a party at the club i used and she wanted to go with me. after a few days i needed some relief and pulled the doll out, i was well into fucking it and i must have been making too much noise because my granddaughter came to see if i was alright, thinking i had fallen and hurt myself, seeing me fucking the doll she didn't know what to do, i explained how i was missing my wife and this was how i looked after myself, minutes later she was under me letting me fuck her tight pussy. we fucked until she went home, but that wasn't the end of the sex, she would drive over after college and spend an hour with me. when she was on her period she would blow me. don't know if she's said anything to her mother, but just lately she's been coming over to help clean the house and do my laundry, the last few times i've noticed her skirts have got a little shorted or she's left a couple of buttons open on her dress. i'm wondering if she is open for a fuck, i'll have to test the water next time shes over.»
