Dave was using his super strength, so carrying the two women was just like carrying two little notebooks; they were very light in his arms. Even if they tried to fall or slip from his hands, he would easily adjust them till they were placed upright on his shoulder.
Moreover, both girls weren't even in the state to think of what was happening to them, as their minds had become so dazed. It was only filled with the thought of the pleasure they were having.
They continued squirting heavily, their love juices flowing like a river, as it fall on the floor. Their legs trembled, and if it wasn't for Dave holding them upright, they would have fallen down in an instant.
Of course, Dave was feeling a little bit of pleasure as he did this, but it can't be compared to the immense pleasure both girls were feeling. As his fingers continued to create havoc inside Ella, her overly stimulated clit which continued to swell more and more, was suddenly crushed by Dave's palm.
