The first couple of tugs on his rod convinced Caius he had been right to place a hand against the wall. His body trembled, and the extra support definitely helped him avoid crumbling in Roxanne's capable hands.
Roxanne didn't quite notice Caius's reactions to her actions. She was far more engrossed in how the organ in her babe reacted to her touch, squeezes, and tugs. When she thought it had achieved maximum turgidity, it proved capable of even more and continued to expand, making her goal of shoving it down her throat all the more daunting by the second.
