Give him the pussy

"Hold on, daddy," I said as I got to me feet. I slid Susan's skirt off, then ditched the thong, pitching them onto the couch. "For being a good boy and getting it up for me, I want to reward you."

I positioned myself with my ass towards him, spread my legs a little and bent slightly forward. Awkwardly I tried to line his cock up with my borrowed pussy as I inched backwards.

When he felt the first tickle of my pubic hair, I guess he realized what has happening. "Oh no, I don't think I can do that! All these years, I've not made love to anyone but-"

I made one quick movement backwards, and he slid perfectly into my wet pussy. He was small, but still felt good. I bet the UPS man would have felt better.

"Don't 'make love's to me then, just fuck me!"

"Oh shit!" he blurted, and he did start to fuck me. I could hear the sound of his body as it hit the wall with each thrust. "I haven't felt something so wet and warm in years."

Across the room an eye appeared in the glory hole, watching me get fucked. I waved and blew them a kiss.

"Oh, Irene," grandpa moaned, then I felt the squirt of his seed inside of me. "Oh...what have I done?"

"Go home, clean up and fuck your wife while you think about me," I said as we separated. "Show her how much of a man you still are!"

"I-I will!" he said.

The eye that was watching me vanished, and a moment later a cock appeared where it had been.
