My twin sister Claire and I had always hated our little sister Hannah, well step sister. Her mother had moved in with us after our parents separated and we had always resented the both of them for splitting them up. My mother had taken the separation very badly and had gone off the rails a bit. Though we lived with her for the first six months after the separation she had spiralled into drink and drugs and social services had taken us away from her and put us back with our father.
We were back in the family home but it felt entirely wrong. The decor was completely different, as was our father. My sister and I bonded as the outcasts oppressively ruled under house arrest.
Our new mother-in-law was a real bitch and tolerated very little from my sister and I, mostly because she knew that given any opportunity we would furiously bully our little step sister. But nonetheless, Hannah seemed to constantly gravitate towards us, always following us around and clinging to our boot heels.
Years later my father and step mother had broken up and for some unknown reason our little sister had opted to stay with him. My sister and I, now both 22 had moved out into our own shared place with a few other friends and spent very little time at home as our relationship with our father was 'rocky' at best.
Having been reluctantly made to return home for an evening to celebrate our fathers 50th birthday we spent the evening sat around with his lecherous drunken friends bombarding us the cliché twin questions that frankly had us desperate to leave. Equally Hannah had been hovering around us endlessly as she sought you avoid the lured advanced of our father's booze-hound single middle aged friends.
In her desperation, she had gestured to us in a frantic attempt to get away from someone.
"Hi guys, could you help save me from this guy. He's one of dad's friends and he's been following me round all night and making me fell really uncomfortable."
First of all, I was furious at her calling our father 'dad', he was no dad to us let alone to her and why should we look after her. I understood why it was happening though.
Hannah had really grown into her body and now at the ripe age of 18 she was a middle-aged man's wet dream. Long brunette hair, athletic build, nice perky tits and a very innocent corruptible look about her. If I hadn't hated her so much I may very well have fancied her myself.
I was just preparing to turn my back on her and leave her at the mercy of this vulgar sweaty pig of a man when Claire, clearly feeling sorry for her interrupted.
"Sure Hannah, I've had to suffer the advanced of Frank's (our father) drunk friends." "They're a disgusting bunch of foul, depraved perverts" she shouted.
Everyone in the kitchen turned to look at her, glaring with seething hatred. I sensed there may have been a history between Claire and one of these men that she hadn't told me.
"Let's go up to my room and get out of here."
For once I was happy to oblige, we were getting some very uncomfortable looks from the other guests and I'd frankly been wanting an excuse to leave for the past hour.
We went upstairs and walked past our parents old room and into what had now been turned into Hannah's room. It had previously been my room and the same that Claire and I had shared until it had been deemed we were too old to share a room.
Sat up in Hannah's room I began to feel extremely resentful of the way our lives had turned out. I realised I was stewing with anger when I dropped my fourth beer by her desk and watched as it fell over and the last few dregs dribbled out over her perfect cream carpet.
I fucking hated her. She'd always been shielded from the hard knocks that Claire and I had been through and now even Claire was siding with her.
I looked up to my sister who caught my eye. She smiled at me with that dark devious smile of hers that I recognised meant she was planning something.
Claire handed me another beer.
"Come on Hannah, keep up. Chris and I have both finished. Now you're an adult you need to learn to drink with the adults."
Hannah looked as though she was struggling a little, swaying a little in her chair but otherwise grinning like her usual idiot self.
Claire looked me up and down again with her conniving expression. I knew from previous experience that if someone had pissed her off and she began looking at me like that then we were both about to get into some trouble.
"You know Hannah, now that you are an adult, some of those guy's downstairs might be right to be interested in you. I bet you'd be a real good fuck. Just look at that tight little body of yours. I bet you've got a snatch tighter than a duck's ass."
Hannah blushed coyly and giggled. Clearly, she'd become desensitised to my sister's coarse language over the years.
"Yeah stand up, show Chris that perky little ass of yours."
Claire took a sharp slug at her beer.
"Come on he's waiting." Claire ushered her up onto her feet and turned her round pointing her ass at me. It certainly was perky.
Claire pulled Hannah over towards her bending her at the hip and pulling her skirt and flashing her white bare ass. She wore a small red thong perfectly framing her tight firm ass but doing nothing to cover the pure white flesh.
"Holy fuck, are you wearing a thong." Claire laughed as she spun little Hannah around and slapped her ass.
"I bet that turns all the boys on at your school. I bet you're a right little goer, blowing the boys round the back of the bike shed."
"No" Hannah replied timidly. "I've never done anything like that before, I've never even been with a boy."
"Oh really, little sister, well you're in luck. Chris and I can show you a thing or two, can't we Chris?" My sisters devious menacing look could be read like a book. You didn't need to have any 'twin bond' to know what she was thinking.
"Yeah, Chris and I can definitely help you with that." With that statement, she pushed Hannah into a sitting position on the edge of the bed and lifted her beer up to her little sister's mouth. "Here finish that off for me."
Claire stood up and walked round behind me firmly grabbing the back of the desk chair I had been sat on and rolled me over next to the bed, handing me another beer in the process.
I popped the beer open in my hand and took another slug.
"Have you even seen a cock before Hannah?"
"No. Well once a girl at school showed us a picture on her phone of one of her brothers friends."
