"That's not Amanda," Amanda said as she shoved past her dumbfounded brother who was staring back and forth between the beer can that was now an impossibly small aluminum ball and the wristband that her flexing had broken. "Do you have another sister?"

"Another sister... No," Robert said as he regained focus and realized his uninvited guest was leaving him behind. He scurried to catch up. "That's my girlfriend Jess."

"Really?" Amanda looked Jess over with a hard apraising look as she stalked into the living room. Jess was a ditz. A bleached blond with barely above average looks and a decent body. Her best asset was undoubtedly her generous bust, it was probably slightly larger then Amandas even was now. Amanda hated her. She was a couple years older than her and was only dating Robert because everyone her own age knew how much of a bitch she was. Robert was enamored with her, or more realistically her bust size. He hadn't been with her long enough to question why an older girl was letting him fuck her and probably hadn't even figured out that she even had a personality of her own yet. "I would have thought you could do better than this sport, the only thing she has going for her are those tits and once they start sagging you're not going to want to be caught dead with her."

"Who the fuck is this?" Jess shrieked as she jumped up off the couch. Amanda could see that Jesses bra was already laying on the floor behind the couch and her boobs did sag...

"If those things are even real." Amanda continued malicously as she bent down to face the shorter girl at eye level. And to showcase that she wasn't wearing a bra either and that her boobs definitely weren't sagging.

Jess did a slow burn, standing motionless as her face turned red. "Hey, that's uncalled for," Robert tried to come to his girlfriends defense. Amanda pivoted on her heel, displaying her goods with the same evil smirk as his eyes once again dropped straight to her breasts.

"Your mouth says no, your eyes say yes." Amanda snorted and stood up to her full height. "Admit it, you'd drop this cow in a second if you thought you even had a chance to be with me."

"What?" Jess exploded and Roberts cheeks flushed red. "Who the fuck is this bitch."

Amanda turned back Jess and grabbed the finger that was pointing at her with righteous indignation. Amanda hated to admit how much she was enjoying this. She flashed a cold smile as she squeezed hard enough to make Jess wince. "Quiet little one, your ex and me are talking, ok? Why don't you just leave before you embarass yourself?"

"My ex? What the fuck bitch... OW..." Jess held her hand after Amanda squeezed again before releasing it and shoving her backward.

Amanda turned back to Robert who judging from how his eyes snapped upward again had been entranced by her ass again. "Like what you see? Dump the dumb slut and we'll talk. She crossed her arms under her boobs like she had before and she rocked gently back and forth on her heel, knowing Robert was getting momentary glimpses of her panties as her leg flexed. "Don't make me tell you twice."

Robert was practically drooling as his eyes roamed over Amanda. She wondered if knowing who she really was would even make a difference to him right now. She almost doubted it would and the thought made her momentarily queasy.

"Robby," Jess whined. "What is going on, tell her to leave right now. Robby?"

Robert finally opened his mouth.
