Naughty stepsister trapped and pounded hard

As I was cleaning mom’s pussy, I heard Tom say “I think she’s ready for some “horse cock” and one of the guys went and untied the horse and brought him to the back of the trailer. I didn’t know what to say so I asked “are you really psychic” and she laughed and said “no silly I followed you’all up there so them Hackleberry boys didn’t kill you. Youporn I didn’t know what it was when I found my mothers swollen clit but I started sucking and licking it like it was a small hard penis and she almost immediately ground her pussy against my tongue and began jerking and grunting until she collapsed on top of me. When we were done, I glanced over to my mom and she was still laying on her back with her legs spread wide open and her gaped open pussy oozing fresh cum down her nice ass crack. We all snickered at that one and I could tell that mom was ok with her. Me and Jack are about the same size 5 ft. Mom asked “was this your first sexual encounter” and I shook my head yes. I was getting really turned on watching my mom with Tom and she knew it. After a while, being the slutty trooper she was, she motioned me over to her and pulled my lips to hers and we kissed this nasty, horny, slobbery kiss while sparring with our tongues and soon I could feel her body sliding back down the trailer to get more horse cock into her needy old pussy.
