Menangkap ibu tiri memukulnya

My stepmom, Lila, just bought some new clothes, and she is LOVING the way her new shorts hug her curves.  She came over to my house to see me, but found me not home, so she made herself comfortable in the living room on my brand new couch.  She finds a wooden ruler and has a light bulb moment - she can enjoy some self-spanking since no one is home and she's feeling frisky!  My stepmom starts out with some light taps, but she soon ramps up the intensity and is really spanking her big, round ass when I walk in on her spanking it.  She's surprised, but not ashamed, and invites me to join her.  I decide since she's punished me before, it is time for ME to punish her for her audacity at being kinky in my living room.  I take her ruler and get her over my knee so I can get in some good smacks, but my stepmom isn't feeling punished, she's just feeling turned on.  Since I clearly can't spank some sense into her, I leave her to her ruler and her red ass cheeks...
