A long time ago I read a story of two pregnant mothers fighting, it was amazing but haven't seen any since.
Those raging motherly instincts really kick in.... 
Once a spanish friend asked me to rp as pregnant.
We argued and agreed to have a sexfight. But since we both was straight, we started slapping each other's cheeks, sitting on a bed, then lead to a little hairpulling with more slapping. Then, with both of us crying, we locked lips, calling each other names, spitting on each other's lips and open mouths and having a sloppy arousing kissing duel, leading to fondle each other's crotch till we cum.
Unfortunately, I don't have the log.
