Of course, she's hot.

Gina stood there looking incredibly hot as I decided whether or not to try to **** her.
"Well?" she prompted again as I continued staring at her.
The prompt helped me make up my mind. "Well, Gina , the thing is, I saw you... in Dan's office."
"So?" she replied, "I am his assistant too, I go in there all the time."
"I saw the two of you... having sex", I blurted out.
I began to continue, "so, I was thinking, I could tell people...", before she cut me off with a smile, "I knew it was you! I was hoping you'd come in and join in."
What? She wanted me to come in and join?
"So, you thought you'd **** me into letting you fuck me?"
"Ummm.... yea..." I replied, sheepishly.
"You don't need to do that you know", she replied as she walked toward me.
Gina walked around my desk and turned my chair so she was standing directly in front of me.

"Let's see here", she breathed quietly as she reached out and grabbed my crotch.
I was instantly hard. Harder than I already was anyway.
"Oooh yea, I knew you'd have a nice size dick", she said as she began to undo my belt.
As soon as she'd undone my belt and zipper, she pulled out my cock and took me immediately in her mouth. She was as talented as I'd imagined, simultaneously using her hands on my shaft and balls, while she swirled her tongue around my head. After a few moments she pulled off then continued to stroke my shaft as she took each of my balls into her mouth in turn. "Mmmm, I do love a nice clean shaved cock Alex," she said in between sucking each of my balls. I placed my hands on her head to encourage her just as she again took my shaft in my mouth, and I began gently urging her to take me deeper as she bobbed up and down on me.

After a few minutes of pure pleasure she suddenly stopped, leaving me feeling empty, but when I lifted up to see what she was doing she was pulling her panties to the side and sliding her fingers in and out of her pussy.
"Get up," she demanded, and as I did she grasped my cock, then laid down where I'd been, tugging my cock towards her as she did so. "Stick it in me already," she demanded as her legs waved in the air, "I'm so horny right now."
Without a further word, I immediately did as she asked, lining my cock up with her slit, and grabbing her feet in my hands I thrust into her as far as I could go. She was wet and tight, but easily able to take my whole length, and I began fucking her in earnest, powering my cock into her as she fingered her clit. Within moments I was close to cumming, her hot pussy contracting around my cock was getting me off quickly. She began moaning as her own orgasm approached and inserted two of her fingers into her pussy alongside my shaft, stretching herself further.
She arched her back as she came suddenly, her pussy spasming on my cock, forcing me over the edge, and to flood her with my cum.

She lay silently for a moment, breathing deeply. "Oh wow, I've wanted that since I first saw you."
"Really?" I asked, somewhat surprised this hot young thing wanted me.
"Yea, though I never thought it would happen until I saw you watching me and Dan, I knew then you'd try, and that I'd let you."
"Oh? Did you want to fuck Dan or..."
"No, I only did him for my job, and then to keep it of course. But you, you're so much hotter than that old fart."
Wow, I'd never thought about myself like that before.
"Anyway, I should get home. Thanks for this Alex," Gina smiled brightly. "We'll do this again, right?"
"You bet," I said somewhat automatically, though to be honest it was totally true.
I packed up my bags as Gina put her panties back on and fixed herself up then escorted her to her car, and drove home.
This'd sure make for interesting dinner conversation... If I decide to bring it up.
