There are some definite virtues in having the spare key to your ex-girlfriend's studio apartment. Chief among them is walking in on her when she's in the middle of fucking herself with a large rubber cock.
Liz was laying on a big old bed she'd gotten after we split up. Since she had no money, I figure she must have fucked someone to get it and I knew he'd gotten his money's worth. Liz was quite the sight; her wavy dark hair framed a lovely aristocratic face and bright blue eyes, her creamy white body with curves in all the right places, generous round breasts, large sensitive nipples, a taut belly sloping down to great hips, a fantastic ass, a tight pussy she had recently started trimming into a neat little strip, and long, lovely legs.
At that moment, those lovely legs were spread wide, her creamy white skin glistening, her wavy dark hair wet with sweat and her aristocratic face flushed. One hand was squeezing her heaving breasts while the other was sliding a huge rubber dick in and out of her lovely, shaved pussy. Her eyes were closed and she obviously hadn't heard the door open. So I stood in the doorway watching as her hips pumped up and down, her hand thrust the dildo in harder and faster and her fingers pinched her hard nipples. She was obviously close to coming.
I figured she probably didn't want just anyone watching, so I stepped inside and threw the door closed. She jumped at the sound. Her eyes flew open and she looked at me, momentarily started and confused. It only took her a second to regain her composure, which was impressive under the circumstances.
"Bastard," was all she said.
"Having fun?" I asked, smiling.
"It's better than you could do," she sneered. "It's bigger," she added, thrusting the dildo into her pussy for emphasis, "and thicker... ooo... and it doesn't go limp right away...ahhh!"
Liz was always such a bitch. I'd only put up with her as long as I did because she was a great fuck.
I walked over and sat down on the edge of the bed, watching her fuck herself furiously. Her hips bucked as she pulled the dildo all the way out and the thrust it back in deep, deliberately showing me the whole length of it plunging into her pussy. Her other hand caressed her breasts, making sure I could see how full and firm they were. Her eyes stayed open this time, locked with mine, angrily trying to show me how much she hated me and preferred this cold plastic cock to mine.
