We don’t want to criticize this young man negatively because when you’re hungry and you haven’t been horny for a long time, the first hole that comes in front of you, you fuck it without thinking about anything else but cumming. This is neither more nor less than what happened to our friend and that is that, as his grandparents were liberal, he agreed to have a threesome with them even knowing that it was the biggest piggery he was going to do and would do in his whole fucking life. His granny couldn’t have been a hotter woman and his grandfather gave him full permission to do whatever he wanted.
