Fisting exchange

She likes to tickle your brain.

My father in law is a really hot mature bi man and I've been sucking his cock and fucking him a few years. He wants me to fist him with one hand and jack him off with the other. So far I've got four fingers in his ass and stretching him to take more. The wife really likes that we spend time together and has no clue. Ive fucked the MIL a few times too.
