My boyfriend and I have found a way to liven up our sexual life, and at the same time please my poor mother, who has been widowed for many years and whom I have never met with another man other than my father. It may seem a little degenerate, but we have gotten a taste for having porn threesomes with her, because we have discovered that her experience in sexual matters, with which I am amazed because I thought she was a close one, has opened up a new world of ideas to make our fucks truly extraordinary. And my boyfriend seems delighted that his future mother-in-law intervenes in our sex sessions, so for now, I think we will continue with this very satisfying practice.
