First a minor detour

You stroll along looking for an information kiosk and just soaking in the atmosphere of the convention floor. You see a lot of enticing targets on the way, but you need to pace yourself, its still early yet. You find an info kiosk with a map and figure out where you are and where the auditorium you need is.

As you turn around you see two familiar figures working at a booth. Apparently Rebecca's book sold quite well and she is now hawking the sequel from her shiny new booth. Walking over, she calls out a greeting, "Hello sir, would you like to buy a copy?" Their cosplay this year is much more elaborate with gently pulsing LEDs and even more under-boob which you approve of.

You noncommittally wave a hand. "Nah, I'm just browsing. I like the art, though."

As you glance over the booth you notice that Leslie has a subtle bulge on her stomach. You almost instantly get hard at the thought that she is carrying your child. Trying to sound casual you comment, "Oh, are you expecting?"

Leslie looks cross for a moment. "Guess its better than being called fat again," she mutters under her breath. She stands up and sticks her stomach out towards you and in a bitter tone says, "Ya, last con some rando came by and pumped a baby in me without even a hello. I know it happens, but you can at least be polite."

Rebecca chimes in, "Ya, it happens when you wear cosplay, but I would willingly get knocked up if we get similar sales to last time. These sexy outfits rake in the cash."

Leslie pouts, "But my breasts are getting swollen and sore, and my back hurts from all the weight. It's really annoying. I wanna go back to the hotel."

"But think of the money," Rebecca responds with a whine. "And it's not like you can get more pregnant." Leslie just crosses her arms and looks sullen.

Rebecca puts her hand on her shoulder. "Would it make you feel any better if I got stuck with some stranger's baby, too?"

Leslie glances up into her eyes as she quietly says, "Maybe a little, at least you would feel my pain, too."

Turning to you Rebecca asks in an apologetic tone, "So, I know it's a bother, but would you mind, uh, as my friend put it, 'pumping a baby into me?' I want to make her feel better."

You are about to explode in your pants just from this heartwarming scene of friendship. You can barely follow the twisted logic brought about by your apparently magical pass but if (sex = photographs/autographs = Normal) then she basically wants you to take her photo, and by photo she means fuck her.

Who are you to turn away a woman in need? "Sure. Guess I could spare a few minutes."

Rebecca lets out a beaming smile as she starts to remove her pants. "Thank you so much, I don't like seeing my friend mad at me."

You slip out of your own pants and come up behind her as she leans over the table, but you don't want it to be like the last time you did her so you grab her and with a startled yelp she is driven into a face-down, ass-up position on the carpet. "Oh! Okay, uh, this works too I guess," she says, as you kneel behind her and slowly penetrate her tight folds. After waiting for a moment for her to loosen up, you start to rock in her slit, waves of pleasure washing over you.

"I don't know, he seems to be much more gentle than the guy who fucked me," Leslie says, as she stands watching over the two of you and the booth.

Rebecca whimpers before looking back at you over her shoulder, "Could you be a bit rougher? I am sorry to ask so much of -ohhhh!" You decide to just go to pound town and start railing this bitch as hard and as fast as you can. She lets out whimpers with every slam of your hips against hers. Glancing up occasionally you see that Leslie is smiling down at her punished friend while subconsciously caressing her baby bulge.

Reaching your limit you empty yourself right up against Rebecca's womb, filling her up. "Ohhhh, th-thank youu...," she slurs against the carpet as you finish pumping her full.

Getting up after a moment, you gesture to Leslie to help you and between the two of you you manage to get Rebecca onto a chair upside-down with her ass in the air so your cum wouldn't leak out. While she appears to be dazed and has some fairly red rug burns on her face and chest she seems to be fine. After getting dressed and waving to Leslie, you leave their booth behind.
