Elizabeth: Beginnings of a Sissy

"In fact, when we were little, Lizzie and I used to practice kissing and dildos. She was even learning to use her backside." My sister breathed lustily, to each of us, licking her lips at him, then winking and smiling ecstatically at me. She then pulled my head close, and kissed me. For real this time. With electricity, and saliva, our tongues wresting, as she placed my hand on her clothed breast, her nipple standing firmly against my palm. She then broke, giggled, and walked back to her chair.

I had suspected for a while now, but now confirmed that I was unable to speak. Actually, physically unable. Nor could I leave the couch, but I was not paralyzed, because I could still twist my hair between my fingers, while smiling as seductively and sexily at Jimmy as I thought I knew. The wine.

My sister had me drink a compound which made me desire to follow her suggestions, and unable to outright refuse them. True, this was a wild dream of mine, but I never expected it to happen. I was turned on, and scared, and I wanted to shout pause and have my sister hold me, but when I tried this is what came out: "I am on my period.", but I said it so seductively I surprised myself. Instantly, as if expecting this, my sister instantly added "So it can only be anal and you can't come in her. I might leak into her fertile womb."

I was shocked. Jimmy had grabbed the bulge in its jeans, and it began to rise. I wanted to run away and lock myself in the bathroom, but instead I watched my hand reach out to slide down his waistband. I clasped his warm cock, pulsing growing, as he undid and lowered his pants. He was wearing nothing underneath, and his thick snake lay, always rising, enlarging, and stiffening. He let go of himself, and my other hand joined the first, as I instinctually lowered my opened mouth onto his head. Gently licking it, working with both hand, growing in my mouth, I finally achieved full erection at 7.5 inches long and just thick enough my fingers didn't meet my thumbs.
