When a girl walks down the street in such a short skirt and with an anal plug, it's clear that she's looking for an adventure for her ass. Licking ice cream is just an added touch to this image of a bitch. So her verbal signs were quickly understood and she even squirted while being fucked in the ass.
They fucked the lady well, nothing to say, and without any preparation! And what was the use of preparation, when she herself was aching with desire!
