Sitting in the backyard of my house, I see my stepfather arrive with a new girlfriend who is blonde, busty, and very beautiful. He introduces her to me as my stepmother! Impressed, I shake her hand and feel a tense energy, as if she had looked at me with eyes that wanted my big cock inside her. At that moment, my stepfather gets a call on his phone and goes to answer it. I stay talking to my “new stepmother” while he finishes his call, and I never expected to hear him say, “Take off your pants because I want to fuck you.” I'm in shock because I know my stepfather is behind us, but I can't think of anything else to do but pull down my pants and show her my big cock. She was impressed and, without thinking twice, she put every inch of my big cock in her mouth...
