Give your sister a test drive
“Come here.” Your voice is filled with lust and excitement as your hands approach Cathy. Of course she flinches as your fingers explore the area under her breasts, and of course her body responds with a painful jolt that makes her wince. “Stop resisting me,” you murmur, paying no attention to her pain-distorted face. “Oh fuck yes.” Your hands find their target and feel her heavy breasts under her thin shirt. “No bra? You little whore.”
“Why are you doing this?” she wants to know weakly but doesn’t resist while you feel her body.
“Because I can,” you say, “Now stop asking. I want to try you out in peace.”
“But…” Another zap, as if you’ve electrocuted her.
“You really are as stupid as you are beautiful” you moan but lower your hands.
“Thanks” Cathy just mumbles but you shake your head.
“Slap your face.” Cathy just looks at you speechless, mouth open, pleading, stupid eyes. You grin as her back tightens and her head snaps up. Your hand presses down hard on her mouth to muffle her scream but only a hoarse croak comes out as her body is wracked by pain. Then your sister raises her hand and you can just pull back before she slaps herself hard. Immediately the pain subsides and Cathy begins to sob. “What hurts you more sister? The slap or my punishment?”
“You-hu-hu” she howls with tears streaming down her beautiful reddening cheek.
“See? It’s easier to obey me. The pain doesn’t go away. Not ever in your miserable, pathetic, stupid little life. You’re mine now. So. Act. Like. It.” You tap with your finger on her sweaty forehead.
And for the first time in your life, you see the look on her face that you’ve always wanted to bring about by humane and kind means. Cathy sees you, recognizes you, and takes you seriously.
“Good girl” you breathe. “Take off your shirt.”
And Cathy doesn’t argue.
Her fingers hook under her shirt and with a moan that is embarrassed to death, she lifts it.
“Make your tits jiggle when I see them” you demand with a dry mouth and Cathy obeys.
“Ethan…” That’s all she dares to say.
Then her big tits spill out and you gasp.
“Fuck,” you moan. Your hands dart forward, grabbing her soft flesh with the lust of a wild animal while Cathy breathes hard and averts her eyes. “I wasn’t sure if I should really do it… if I could” you confess, bobbing her titflesh in your palms. “But your melons are so slutty, one just have to…”
“No…” But she doesn’t resist as your tongue glides over her nipples. They are soft, clearly not aroused.
“I know you don’t enjoy it” you growl, switching breasts. Your fingers squeeze a little harder, pumping blood into her nipple. “But you still have it easy.” You look up at her, “Say ‘Thank you Ethan for making it easy for me’.”
Cathy doesn’t want to submit. Two shocks to her body change that.
“Thank you for making it so easy for me to submit to you, Ethan.” She’s already showing some enthusiasm to please you.
“You know, the spear is more versatile than just punishing you for doing something stupid,” you say while playing with the most magnificent pair of tit-flesh you’ve seen your entire life.
Who the fuck cares if she is my sister if she has this amount of touchable flesh on her body?
You know Cathy won’t resist you, but her eyes betray her sheer horror as you begin to undress. “I could order you to love me, you know? Do you know what would happen then?” Cathy shakes her head and looks anxiously between your legs, then in your face. You almost want to ask her if she’s distracted by your throbbing cock in your old underpants. “Then your brain would punish you until you believed it.”
“My God… Ethan… please I…” Your cock leaps into the open and Cathy gasps. This is the kind of reaction you’ve always wanted and never gotten, so you take what you can get.
With one hand you push her back on the bed, the other massaging your cock a bit. Then you put your hand on her mouth and press shut. Cathy has to look at you while she has your smell in her nose. Tears trickle down the back of your hand while you explain the new world to her.
“Maybe I just like you too much, not just sexually” you grin sardonically “but as the sister you could be. So don’t worry, I’m not planting any new memories in your head. Isn’t that nice of me?” Cathy nods eagerly while her panicked breath warms your palms. You take your hand away and want to say something but your sister is faster.
“Thank you for being such a nice brother Ethan.” You raise your eyebrows.
“Good girl,” you praise her eagerly. “And you didn’t even have to punish yourself.”
“Yeah,” she sobs. You know she doesn’t believe it, you, being a good brother. You didn’t give her the understanding that ‘don’t lie’ means to be true to herself, believing, not only following orders and thinking what you want. But you don’t care. You still have plenty of time to break her, mold her, whether with force or time. For now…
“In what position do you want to be fucked by your little brother?”
“Ethan…” You have to pull back and wait patiently until the shocks stop. It takes almost a minute in which Cathy starts drooling uncontrollably. Amused, you watch her lose more and more control over her body.
“You’re going to piss yourself like a bitch if you don’t hurry up” you laugh as her legs kick and twitch uncontrollably. A life without love and caring from her side makes it easy not to see a real human in her but only a distant person. Yes you ara a sick fuck but it isn’t personal. Cathy is strong, but your intelligence is stronger.
“Doggy!” she finally gasps and goes limp on the sweaty mattress like a doll.
“Then go hop and up you lazy bitch.” Your hand slams down on her ass and you decide to help her with her pants. You don’t hear the sobbing as Cathy gets on all fours in front of you on wobbly legs, her arms outstretched and weak. You see only the tight slit in front of you, unwilling but finally within your grasp. And you do. A soft scream escapes her throat as your hand grips her labia and squeezes so tightly that your sister’s body tenses.
Quickly you get into position. Images and fantasies flicker in front of your inner eye, willing, in love, beautiful girls look over their shoulders to you, wanting you. Cathy is at least beautiful, otherwise, your glans would not slide through her dry cleft now.
Then you understand that you don’t have to wait. Cathy will not enjoy it. She won’t help you. As long as you don’t want her to, Cathy won’t want it. But you don’t care. Your sister had her chance and now it’s your turn.
Never again will you wait for something you’ve been hoping for. Be it affection or a cunt.
Without further ado, you sink into your sister.
