It starts with you walking into a room, wearing tight clothing, preferably stuff that you would wear before you where pregnant. You start talking to me, your step brother, talking about how full of cum you are because you just got done sucking a bunch of guys off at a party. You would be rubbing your belly, burping, and talking about how full and tight your stomach is. You start to get horny again, and offer to suck me off around half way through the video. I agree and you suck me off, and I cum into your throat, and in the last minute or so of the video you stand up showing how much more I made your belly grow, and at that point you would be maybe pushing your belly out making it look bigger.
