Looking around for something to calm Bill down; Tammy spots a pant-like object on a hanger within Bill's reach, "Oh try the thing to the left of you!" she shouted.
Distracted by the way Tammy was looking at his butt, Bill reached to his left and grabbed whatever was there. "Huh? B-but these seem even smaller than my pants!" he stammered... but before he knew it, he was already wearing them. The tights stretched to hug the curves of his butt, and shaped up his legs to match. Once the tights were in place, he took a few steps to Tammy only to feel a rush of pleasure from how smoothly his legs slid past each other, he felt his dick grow hard inside his panties; and began to feel embarrassed when he realized he could also -see- just how hard he was just by looking down.
Tammy's eyes nearly pop out of her head in excitement. Something about this sight had kicked up a feeling she did not have the slightest idea how to suppress. She ran over to Bill and grabbed his hand, he could feel how clammy her hands were as he noticed the overly energetic look on his girlfriend's face. Before they both had any idea what was going on, Tammy had dragged Bill into one of the changing rooms and locked the door.
"T-tam-tam?" Bill tried to drudge up an old pet name to try and snap her out of whatever had possessed her, but to no avail. Once the door was locked, Tammy grabbed Bill's hips and spun him around. She grabbed his ample booty and yanked down the tights and panties. There are no words to describe the quality of butt Tammy was witnessing... and soon she couldn't help but to shove her face square into it and eat it out.
The sudden sensation of a tongue entering his butthole made him gasp, and his dick sprung even harder; but somehow his attention was now drawn to the article of clothing hanging from the wall that Tammy just shoved him into...
