The talking/description in their first real lovemaking scene together

I found the way Therese was describing what Isabelle was doing to her -- licking her "pearl"/clit, and going back to it again and again, sticking 3 fingers insider of her, etc, -- was totally hot. And so was the description when Therese reciprocated. One didn't need to actually see the graphic display of what was going on because Therese was providing the oral description, and that was even better.
