Fuck that pussy.

You slide into Jenna's waiting vagina, and soon the room is filled with the rhythmic slapping of your crotch against those gorgeous ass cheeks. Each thrust shifts the desk a little as you pound Jenna's pussy. After almost 20 years, you know every spot to hit, every little piece of her sexual topography like a road map, and after 30 seconds or so, Jenna is rubbing her clit with a free hand and moaning out her orgasm into her other arm.
It feels incredible and satisfying to reduce her to a whimpering, trembling pile of orgasm, but unfortunately, you've come to recognize when it's not going to happen for you. After a few more obligatory thrusts, you pull free and sit down. Your cock is starting to subside, but you know better than to look disappointed.
Jenna straightens up, her makeup a little smeared and her dress a bit disheveled. As she straightens her dress and locates her shoes, she rubs her pussy thoughtfully.
"Did you....?" she doesn't have to finish the sentence. You give a smile and a brief shake of your head.
"It's all good."
Her face is unreadable as she slides her panties back on. "Well...thanks for the good dick, baby. I got to go," she plants a peck on your cheek and sways out of the room.
You grip your softening dick in frustration. What's wrong with you!? You know the answer: porn and jerking off, combined with getting older.
You tell yourself its not a big deal; sex isn't everything, especially in your relationship with Jenna. But the looks she gives you when this happens don't make you feel like a man.
