I sit down with my step-son explaining how many of his friends step-moms have started cuckolding their step-sons. I tell him even though cucking sometimes looks mean in porn, it can really be sweet way to share an intimate experience like sex. I confess I have been masturbating to the fantasy of him watching me getting fucked and orgasming as I watch him stroking and ejaculating, getting off on his step-mother’s pleasure. Then he confesses he wanted to ask me about it too. He even has a well-hung friend who has been fucking his other friends’ step-moms waiting outside in case I said yes, which of course I do. I encourage my step-son to stroke while the friend fucks me from behind. I'm shocked by how large my step-son’s cock is, even bigger than his friend’s. I ask my step-son if he enjoys watching his step-mom getting fucked in the pussy he came from and telling him how wet it makes me to see my own step-son stroke for his step-mother. I teasingly call him a pervy cuck-step-son for kissing your step-mom while you’re stroking your cock. The friend starts to creampie me which makes me cum and my step-son blows a huge load I am so happy I start caressing his cock, which makes him hard again, so I stroke him off a second time. I snuggle with my step-son and eagerly agree to keep cucking him, because having him watch me made me cum so hard.
