At that point my eyes slipped down her body, her succulent form was being covered only by a tight white nightgown. I instantly started thinking impure...thoughts, she was my sister, my twin sister but she looked so beautiful and sexy that it was as if the world's greatest artist had painted her nightgown across her curves. I realised that she had been talking to me this whole time and I hadn't been paying any kind of attention to her words. Her hand latched onto my arm as a way to get me to. . As i neared the stairs leading up to the second floor i heard music...I decided to scare Brandi so i went into the spare bedroom that connected to her room by a bathroom... when i flung open the door i couldnt believe my eyes. There was Brandi face deep inside of a pussy.. When she realized someone else was in the room she jumped back and gave a half scream..I collapsed to the floor!When i realized the other girl was heidi it didnt give me much relief, hell it may have made it worse...!. I was darting and wiggling my tongue around in her ass hole as sphincter relaxed allowing my tongue to probe deeper."Oh yes, that's it, fuck my ass with your tongue, Slut-puppy," she cried out moaning and grinding on my face. Suddenly she pulled my head back and spun around switching legs on the vanity, her voice almost a growl, "I need you to eat my pussy NOW! Slut puppy," she ordered as she pulled my face into her pussy again. "That's it, suck your wicked stepmother's pussy, Slut-puppy," she. My wife mether match and is now carrying his child and I have been consigned toHelen's oversight. She's a much harsher taskmaster than Heidi ever wasand will not be satisfied unless I am completely under her will.I don't blame Heidi for her behaviour. She married a man who was unableto give her what she needed sexually and Helen fixed that by making me aeunuch. She eventually reversed that process but it was too late. Thedrugs she gave me to temporarily chemically castrate me were overcome.
