Yes

"But, Samantha." You are now torn. You want to help your friend, you'd love to fuck this gorgeous woman, but to impregnate her and keep it a secret? Yes, you could do that, but...

"John, please???" She has never sounded this way, you are hearing from the little girl who grew up to be this beautiful, professional woman, who wants some deep biological need filled. "I'm totally serious, John, I want you to try...please."

It's six thirty now, the Google office lights automatically start going off. All the staff left over an hour ago. Your inside office does not have windows, there is a couch, two chairs, and a doorway, no door. Cleaning people arrive after midnight, and two are totally alone. "Are you sure?" You ask again. Samantha begins to unbutton her blouse, then unzip her skirt, dropping them to the chair she was sitting in. Next, she unfastens her bra, tossing it on her clothes, and steps out of her pink bikini panties. Her body is skinny, she is totally aroused, with nipples that look delicious, and you bend over to begin kissing them. She caresses your head, holding you against her breast, and then moves her hands down to unfasten your belt and unzip your pants. She gently caresses your erection, feeling along its length and thickness.

"Mmmmm, John, it feels wonderful...so big...damn, it's the biggest one I've ever felt." You are now walking together, still kissing and fondling, but toward the couch. You step out of your pants and underwear and pull your shirt over your head. You kiss down her flat belly to her small bush, and she parts her legs to let you lick and kiss her swollen clit. "Oh, I miss that, fuck, do I miss having my pussy licked." You spend more time, and she is clearly getting aroused, her pussy begins to ooze clear, slippery fluid. "I am so fucking fertile, John, do me."

You pull her hips toward you, and gently insert your penis between her legs, which are now widespread. It easily slips into her and you begin the process of slowly fucking her pussy, driving in a little deeper with each thrust. Her pussy is firm but open and easy to fuck. She is snug enough to be pleasing, but loose enough to fit your thickness into her. She moans with each thrust.

"You are the biggest fucking dick I have ever had, John. Damn, if I knew it was so big I might have done this sooner." Suddenly Samantha shudders. "Oh, fuck...Uhhh....fuck, fuck, fuck...John...I'm gonna cum!" You feel her pussy tighten around you, and it starts, a contraction that forces you to push all the way into her, then firmly massages your penis until it reaches the end, squeezing the very tip, and causing you to also cum. Your penis erupts inside of Samantha, you feel it deep in her, the pressure caused by you filling her, and suddenly it's released as her body sucks the fluid deeper and another contraction starts at the base of your penis, again, massaging you until you shoot another load into her. Samantha is moaning deeply with each contraction, and she pulls you toward her mouth, kissing you wide open mouthed. As your orgasm slows, she is panting, then suddenly goes rigid, cries out "Oh, fuck!" and a second orgasm comes along, this one deeper inside her, but still massaging every drop of semen from your penis as it softens some. Samantha is panting hard, her chest rising and falling, her small breasts firm, her nipples huge and poking as she wraps her legs around you, "Uhhhn....uhhh...oooooo.....oh, fuckin...damn....mmmmmmmmmm." She trails off and passes out for a few seconds. You are still kissing her mouth as she slumps onto the couch. Her eyes blink open.

"Oh, Samantha, that was the most fantastic sex I've ever had." She kisses your mouth, holding your back, sliding her hands down to your butt.

"Do it again." It takes a few minutes to get yourself aroused again, she helps by massaging your penis with her hand, then guides it into her pussy again. "Give me more, give me the baby I want, John, and you can have me anytime you want." You know that is not what will happen, but you are now overtaken by the act of fucking this beautiful woman who you have wanted since the first day you saw her.

The next morning the two of you ride up on the elevator together. You have already agreed that nothing will be said about what happened, and your relationship will return to what it was before. You both work very hard at that, and actually it seems like things have returned to normal. Samantha is back to her normal self, and while you dream of what you did, as she does, too, neither of you let on.
