You come home to your adorable diaper girlfriend in a soaking wet diaper. You've been at work all day and your diaper is wet too. So I suggest we make our diapers even wetter by rubbing them together until we cum. The bulge in the front of your diaper tells me you really like this idea. I take off my t-shirt and play with me titties for you, then I straddle your lap and grind my hips. I can feel your hard-on rubbing against my clit through the diaper and it feels so good. I decide to give you a nice view of my padded bottom, and turn around to bounce up and down on your diaper cock. Finally we're both getting so close, so I turn around and rub your diaper with mine until we both cum hard. Feeling satisfied I lay back with a sigh. You're ready for a diaper change, but I think my diaper could hold a lot more. Maybe I'll take some laxatives and mess for you, really get this diaper sagging, before I change. We might need to change your diaper again soon, too...
