What The Wife Doesn't Know...

Jessica continued up my body until she was straddling my face, but instead
of giving me her cock to suck as I thought she was going to do, she moved
further forward, lifted up her hairless balls, and offered me her
asshole. Remembering the pleasure I had received from her, I eagerly thrust
my tongue into her ass, forcing it inside, coating her asshole with my
spit. Jessica leaned back and slowly jerked on my cock with one hand as I
tongue-fucked her ass, going as deep as I could, in and out with my tongue
like she had done to me. With her other hand, she pulled her own cock back
to erection, and was soon gasping and moaning with pleasure.

I was poking and thrusting my tongue deeply into her asshole, when she
pulled up and moved back down until she was straddling my hips. She lowered
her ass until my cock nestled in her spit-lubed asshole, and slowly worked
her ass until it began to open up for my cock. In one movement, she forced
her ass all the way down over my cock, until I was all the way inside her,
her sphincter throbbing around the base of my shaft. The heat and tightness
was unbelievable, and I strained to push as far into her ass as
possible. Jessica's eyes were closed and she was gasping, lost in the
pleasure of having her ass penetrated. She opened her eyes and slowly
lifted her ass up the length of my cock so that just the head remained
inside her, before plunging down to completely envelop my cock again.

She rocked on my cock, forcing it in and out of her tight ass, her own cock
leaking precum onto my stomach, bobbing up and down in time with her motion
on my cock. Her eyes were closed as she once again lost herself in the
pleasure of having her ass fucked. I reached up, and played with her tits,
pinching her nipples, enhancing her pleasure as she rode my cock. One of
her hands was on my chest, helping her keep her balance while her other
hand jerked on her cock, and fondled her balls. The pressure was building
in my balls again and I began lunging up in time with her own downward
thrusts.
