They'd shared a cab on the way home. They'd stopped at Chelsea's address first and David told the driver to wait for him. He'd accompanied her to the ...ront door and into the unlit vestibule of her building. They'd made plans to visit an art exhibit the next day and Chelsea was already looking forward to it. David had drawn her into an embrace, kissed her lightly on the mouth and told her how much he'd enjoyed being with her that evening.Then, instead of releasing her he had suddenly bent her. Eliza's forehead creased up in confusion but before she could ask, Elizabeth suddenly kissed her full on the lips. She felt her sister's lips soft against hers. They felt lovely. She found herself kissing back to her full surprise.Eliza gasped as she felt her left breast being touched as she leaned back and her twin sister laid on top of her kissing her with passion. Eliza wore a short denim skirt and her legs parted, wide enough for Elizabeth to glide her horny left hand up her sister's skirt. He took his chance, wrapping his arms around her waist and pounded her pussy as hard as he could. She squealed loudly, more from shock than pleasure. He took this as a good sign, fucking her as hard as he could muster. He was close and they both knew it. “I am going to cum, fraulein, I'm cumming.” He slammed for a few more second before collapsing on top of her. His cock erupted deep inside her, filling her pussy with his seed. She groaned, holding him close, till she pushed him off and climbed. After dozens of intimate online conversations she's still a mystery in many ways. From the faceless photos I know that she's tall, at least 5' 8". She's educated, mid-twenties, probably a professional and has a good job judging from the clues she let slip.I don't know her real name or where she lives. But I know her, her fears and insecurities, her fantasies and fetishes in ways only the anonymity of our relationship will allow, like talking to a stranger on a plane. She keeps me at a distance.
