"Hey Sis you need to be...," brother Tim said as he burst into her bedroom and stood there standing then with his jaw dropped and mouth open, stunned by what he saw, his younger sister was there seemingly as changed halfway into being a cute goat.
Horror struck, she turned to face as stare with her rectangle pupils at her brother. The staring of each at the other, it was a Satyress sister who won and held her foolish brother in a mesmerized trance as she approached him.
"Tim oh Tim what I have for you, as something new in me tells if you kiss me and we mate, your penis in me then you become a satyr male. Or, if you kneel and with that open mouth you maw my horny feeling pussy, licking me with your tongue, tickling me to orgasm, then you shall cease to be a brother and become as my older Satyress a sister." Sister said to her never timid brother, Tim.
Tim stood there wide eyed and his eyeballs rolling around like a lunatic form an insane asylum. He reached his arms out level to his shoulders and with his hands be began to fondle the breasts and teat-size nipples of hes aroused goatish sister. He could not begin to understand her control over him, he a football lineman, and some hundred pounds of sheer muscles more than his cute if horny sister.
Sounds of others in the household waking as moving about made reason for closing her bedroom door and deciding what course was best to hold her control over Tim.
