Elizabeth: Beginnings of a Sissy

As I started to eat her out, a much thicker liquid oozed out, with a brand new, but delicious taste. Unlike her girlcum, though, it soon ran out. She giggled, and dismounted my wet face, reaching for her remote. Turning on her TV, she played a recorded movie. It was me, dolled up, tongue out, as her pussy dripped man cum into my eager mouth. I had just eaten her boyfriend's fresh cum. Before this could process fully, she interrupted.

"Jimmy wants to meet my cousin, visiting from BC. Please, come?" She spoke it like a question, but we both knew it wasn't. I didn't realize then, but at that moment, she knew she owned me. She quickly braided my jaw length dirty blonde hair into pigtails, then she grabbed a pair of her purple white striped cotton panties, applied a pad from her dresser, and dance slid into them, sliding her hands under her skirt.

"Wait, what should we call you?" she asked me, smiling in a supportive, evil way, perhaps to herself, but she was a little taken back (pleasantly) that I instantly had an answer.

"Elizabeth Jessica...Lizzie." I said, demurely, twisting my leg, clasping my hands behind my sashaying skirt hem. My sister laughed, and smiled. "It's beautiful, Lizzie. Oh!" she bolted off to her en suite, returning with a box of tissue. "We need to fill you out." She said, sticking out her 36c chest at me to emphasize.

As she began stuffing and forming my new tits, I asked if Jimmy'd notice the lack of makeup, or Adam's apple. She shook her head. "He's drunk, and not the brightest on his best day. Think of this as your first test, to see if you can pass in public as Lizzie." I don't know if she meant to, but I distinctly heard the word 'first'. There would be more? She finished forming me, and from a clothed view, I had fantastic tits.

"Just one more thing. It's probably nothing, just think of it as extra protection."

"Protection from what?" I asked, as she reached her hands up under her skirt again. They came into view holding her maxi pad, now stained with blood. It was her period.
