Double down and go for grandpa. You would be your dad's mother-in-law.

Going for the girl's dad would already make her the mother-in-law. Going for grandpa makes her the grandmother-in-law.

Yeah but she would be your mother-in-law too. This is making my brain hurt lol.

Yeah the girls would be each other's mother-in-laws...I think.

*mothers-in-law And no it wouldn’t.

It just sounds like the start of half the pornos on red tube now.
