As Vivian recovered from her orgasm, she asked me.
"Haa... Arthur... haa... I want your cock. Please put it in me."
I nodded and pulled down my pants, showing off my raging erection. I grabbed it with my hand and slowly pumped it up and down as I positioned it between her crotch, showing how big it was.
I got on top of her and rubbed it on her slit, giving Vivian a preview of what she was going to experience soon.
She breathed in, her body still hot from the orgasm. Then she spread her legs and said, "I am ready... put it in..."
"What's wrong, Mama?" Eliza asked. "Are you scared? I have seen him doing it to me before. It is not that scary."
"Ah... I know..." Vivian's face blushed from embarrassment.
Then I slowly pushed forward, entering her slowly.
"Ah!" Vivian let out a sudden moan.
She was so tight and warm. It felt like my cock was being sucked into her body.
