These granddaughters will go far! Only real pranksters can wish Grandpa Happy New Year in such a way. And they wrote a letter to Santa that they want a big and hard cock on New Year's Eve - so he gave Grandpa a dick, which satisfied both of them. I wonder what Grandpa wrote to Santa Claus then? ))
Considering the condition of the grandfather's device, I do not see anything surprising that the granddaughter let him clean her hole (I would even say, she begged to do it herself, apparently it itched a lot).
