Knocking on Helen's backdoor

Helen kept sucking away on the stranger's cock, her head bobbing up and down the shaft. She was again trying to suck every inch of a man's cock down her throat.

My cock was still rock hard. I slipped two fingers into Helen's cum-filled pussy, slowly churning them in and out. Helen moaned; she obviously was enjoying the fingering. I wasn't sure she would like what I had planned though.

Easing my fingers out of her pussy, I slowly probed her now-slick asshole; she didn't object. I popped one cum-coated finger into her tight backdoor. It eased into the warmth. I wiggled my finger. Helen, never slowing down on the stranger's cock, again moaned. A second finger followed the first.

With two fingers deep in Helen's ass, I began fucking her. Easily and slowly, I pulled my fingers back then slide them back in. I couldn't believe it that Helen, who would never have let me touch her here, was obviously enjoying the sensation. She was even grinding her ass back toward me. It was time.

While her mouth was still occupied with the stranger's cock, I slipped my fingers out of Helen's ass, lined up my own hard cock, and plugged her hole with my cock. I felt my wife stiffen. Was she going to scream in protest?

I then realized that she was furiously gobbling down the stranger's cum, sucking deeply so she wouldn't lose a drop. I pulled back slightly and pushed forward. Helen wiggled her ass. I began fucking her, slow and easy at first, but as she moved in rhythm with me, I picked up speed and power.

Helen released the stranger's now-soft cock; it disappeared back into the gloryhole.

"Oh, god, Jeff," she was panting, "it's so dirty. I can't help it. Fuck me!"

I drove into her ass good and hard.

"Oh, yes! Fuck!"

I rammed my cock home, deeper and harder. I was fucking her now, fucking with power. My sweet wife wanted it. She begged for it.

I felt my cum rise up again. I wanted to fill her ass with cum. I wondered if that is where she wanted the sticky load.
