So my naughty boy now knows that he has made step-MOMMYs belly swell and I want to give you a special treat. My step-SISTER Zoey Andrews is visiting and I want her to enjoy the pleasure of being with you and making her belly swell too so we can share the awesomeness of having your babies at the same time. I guide you inside her and lick her clit at the same time as we all enjoy this proud moment of you spreading your seed inside her. We will both have swollen bellies and big fat full tits.
