Bubbles' thigh was not unnoticed. Very much the opposite, as Boomer couldn't help letting out a little groan of pleasure. One got by him because he didn't expect himself to react that way, but from then, they were only little sounds in his throat. It was obviously making Bubbles uncomfortable, despite her continued stimulation. If he let loose and showed how good it felt, she'd either run away or pass out on the spot. Though if she knew what exactly a hard-on entailed, she would know from the now rigid state of him that it felt very, very good.<br/><br/>Truth be told, it did hurt a little where the tip had wormed it's way through the opening in his boxer shorts and pushed against his zipper in an effort to touch the skin of the leg that had awakened it. He truly believed it would break the zipper, if not make his jeans explode, if she kept up what she was doing. And yet, he didn't ask her to stop or even slow down. "no, it doesn't hurt. it<em> really </em>doesn't hurt." As he said 'really', his voice betrayed just how far from and at the same time close to pain the feeling was.
