The big day is coming up - her daughter's wedding - and Mrs. Smith is very excited. She wants to make sure everything goes right, and that includes the wedding night. So she shows up at her future son-in-law's house and tells him she wants to show him a few things.

"You have to know how to take care of my daughter," she says.

She means her daughter's needs.

"I have to know how you treat my daughter in bed," she says.

She finds out by sucking Benjamin's cock. She makes sure he knows how to eat pussy. And she definitely finds out if he knows how to fuck.

Turns out he does. The problem is, now he's going to want to fuck his mother-in-law, not his new wife.

Mrs. Smith, or Firegirl, as she calls herself, is a 44-year-old mom who grew up in Poland and lives in London, England. She describes herself as "spontaneous," although what's going on here was definitely planned.

"I have a day job," she said. "I also do modeling."

And in-between, she fucks her future son-in-law.
