OMG! Twee nymfomanen, sperma-hongerige stiefzussen zuigen je sperma eruit.

Me and my stepsister can't get enough cocks, so we start betting endlessly. Who gets more sperm and whose cocks squirt first? The men only have one condition: a two-week ban on squirting in order to be able to squirt even more at the place of the bet. Which one of us has won?
