My stepmother is young, beautiful and has huge boobs! She's also super kind, and I was worried about being a virgin, so I thought I might have a chance, so I told her, "I want to have sex," and she said, "If it's okay with me..." and she readily agreed! So I went for my long-awaited first penetration! But even after I ejaculated, I still wasn't satisfied. And I didn't lose my erection at all. So I inserted it again! But it's still not enough? I'll fuck her until I'm satisfied! So I chased after my stepmother and inserted it again and again!
