Mom also puts her ass at my boyfriend's disposal

The day my mom met my boyfriend was the first day my mom had a threesome for the first time in her 70 years. Of course, my boyfriend is used to it like I am because we are a liberal couple, but my mom would never have considered something like that, to be honest... so you're going to see the story of that day and how she immediately had her ass at my boyfriend's disposal, which he didn't waste, of course.
