Well over the years we have been married my wife has always teased my dad which he has enjoyed immensly ,
I just left them to enjoy their little game ,like he would come into the kitchen as my wife was washing the dishes and he would just rap his arms around her from the back and if he thinks I'm not playing attention he will press himself up against her and his hands will come up over her tits just for a second or two,
If he is over at ours I can be sure that when he goes home he has left hand prints all over my wife and she comes to bed gagging to be fucked, lol
He has seen her bare tits lots of time and had his hands on them when he would tell her she has the best pair of tits he has ever seen which she laps up,
I did walk in on them once with his hand down her jogging pants and she told me in bed that night that he had a finger in her pussy when I walked in just as I was sliding my dick into her hot wet pussy, we fucked for hours, lol
He doesn't seem to want to go any further than looking at her or feeling her up when he gets a chance,
I did ask her if he pushed it would she let him go further and she said well he has a nice big cock and I'm sure he knows how to use it,so maybe, maybe not depends on the situation at the time,
She knows I wouldn't be totally against it so I guess you never know how it will go,👍
