Sophie tit-fucks her

I helped Sophie up the steps of the bus, her pregnant belly making it harder for her to climb stairs, before we found our seats in the front. The seats were big enough for three students each, with at least a few feet's worth of free room for each, allowing the students free fucking room.

I sat down, only to see that she was still standing in front of me. She gave me a flirtatious smirk before she got on her knees and grabbed my cock from beneath my skirt. She stroked it, inflating it from half-erection to full-on "ready for fucking". She grabbed my shaft with both of her hands, stroking it and licking the head and side, making sure to trail as much spit as she could as she did.

"My mom told me her girlfriend loved it when she did this to her when she was pregnant with me," Sophie said as, to my amazement, she grabbed her swollen boobs and raised them up until the tip of my cock slipped between her cleavage.

Before her pregnancy, Sophie did not have much upstairs to really speak of, her breasts almost flat before. When her stomach started to swell, her breasts swelled along with it, becoming one of my favorites parts to grope.

To have my first tit-fuck with her was wonderful. The soft, squishy pillows that engulfed my cock, the cleavage formed by her tight-fitting, transparent brassiere created almost a perfect recreation of Sophie's wonderful, wonderful cunt.

Sophie looked at me with those sparkling eyes and I knew that that was the final thing that drove me over the edge. I came like a fire-hydrant, ropes of cum shooting and covering her face and hair with my seed before she wrapped her mouth around the head, my girlfriend drinking whatever cum she could get.

As my thunderous orgasm slowed to a crawl, Sophie detached her lips, her cheeks full of cum as she swallowed it in front of me. She gave me an optimistic smile.

"Mom says that protein is good for the baby."
