I was so worried after finding out that my step-son has a medical problem! He was very private about it, so I asked him to see a doctor urgently. Today he finally opened up to me. I couldn't believe my ears when he said he has hyperspermia! My pussy got dripping wet instantly at the thought of him throwing ropes after ropes of cum in my mouth, on my face and my big tits! I gave in and confessed that I'm addicted to cum... then I shyly asked him if I could suck his dick, to see for myself how that condition is manifesting in real life. He's always had (not only) such a big heart, so he accepted! Drenched in his cum, I am the happiest step-mommy in the world
