Your sister's warm interior

Her lips feel like fire, even when surrounded with such warm waters they burn you. Her hands grab your head with need. You hear her moan. It is brief, intense, it dies fast. As soon as it started, it ends now. She moves away, eyes filled with regret.

"I-I'm sorry!" She says. "...God, I'm just like her, aren't I? I'm molesting you..." You don't know what to say and she is quite fast to misinterpret your silence. "We better leave this like that." She starts to get up, but you don't want her to. You take her hand, she stops, she looks at you with hope, the valleys of her pussy just before your eyes, outside of the waters, almost as a second pair of eyes that gaze as powerfully. All of her eyes, the real and the imaginary, look at you, both with guilt and need.

"Please, don't go. I... It feel fine." You know what gate you are opening, you know the flood that comes behind it. You know she is your sister, even if she had a different father, you know such thing should bother you, but it doesn't. You know it now: having sex with lady Cassandra didn't felt so wrong because she was your mom, but because she was so rude and mean... You want to be treated nicely, by a nice woman.

"I don't want to **** you..." She says.

"I know you won-" She doesn't let you finish.

"I want you to **** me..." She moans in a soft confession.

You don't understand what she could be meaning. She kneels down again, closer to you, inside the warm waters. Her arms surround your neck, her lips are again close enough for another kiss.

"We are both a mess, aren't we?" She says. "We are torn apart between what our mind needs, what our body needs and what we are supposed to desire... I always want to do nasty things, but they are not what a lady Barton is supposed to desire and now... I also want to be nice to you I think you deserve it... I... I'm not my mom. I'm better than her, I can prove that, I want to prove that... If you let me."

"I'm a mess too." You admit. "What your mom did still hurts, but I... right now, I find you so pretty."

"Really?" Her eyes shine just a little.

"Yes."

She bites her lips before speaking. "Would you... Would you fuck me? I know is a big taboo but I don't care... I don't want to ride your dick, fuck, I-I want y-your dick to m-move into me."

"Like s-stabbing you?" You say, not fully understanding.

Her eyes are open wide, they are so close, so beautiful."Fuck yes... Stab me..." She kisses you again, and you can't help to return the kiss. "You'll mark the rhythm... it will be at your own pace, ok? I-I'll be a bit passive, ok? ...N-no pushing... And you... you stab me... Please..." She moves to the very end of the tub, arms to the side, legs spread. She is completely open to you and willing to receive you, but she is nervous too. Her tinny and perky bosom moves up and down, she is breathing so fast. She looks at you so intensely. It's so weird seeing her like that, always so in control, always so haughty and controlled. "Please Mark... I won't resist you... U-use me. You c-can be mean."

Your legs tremble too when you get closer to her, you had never heard of this kind of sex, you never knew of a woman who wanted to be submissive to a man, to be the one that receives the other, but she wants it so badly. Someone like her is specially not supposed to enjoy being so powerless, it's such a taboo, such a weird thing, her being your secret half sister seems almost unimportant now. When the tip of your cock touches her folds, her legs shake and her eyes are closed in a moan. She is burning, even among the warm waters of her bath, she is burning. She cries when your first stab slides so easily into her, buried to the very hilt.

"I won't resist..." She says... "I'll be a good girl..."

You start moving into her, in an out, she feels so warm and needy, she trembles and moans at each movement, her tits emerge from the waters, with nipples so stiff they could cut, two legs that also want to be conquered. She looks directly at you, her mouth half opened, split dropping for her. She starts to talk to you, narrating her fantasy.

"I'm the pampered rich princess... the haughty lady Barton... and you are still that peasant boy, you were supposed to serve me and be quiet. But I ve been s-so mean to you, calling you names, and giving you orders... and so you are all fed up, you had enough of me being such a tease and a bitch. I need to learn a lesson... There is a revolt and you maids are assaulting and robbing us, stripping us of everything... Other maids are taking the jewels and the money... but you have come for me."

"You were... taking a bath..." You try to continue, as you fuck her so softly. You just say obvious things, you are not use to this kind of fantasising. "...you didn't expect me."

"YES!" She sounds so happy to hear you participate. "I was so ****, but still so smug and mean. I looked at you like you were nothing, 'the hell are you doing here, scum!?'" she says, exaggerating her own voice. "But that didn't stop you, not this time."

"D-did you scream?"

"Make me."

You move your hips in a single burst of energy that must have felt like a real stab. She screams, as promised. For a moment you fear having actually hurt her, but then her hands crawl over your chest, both pleading for mercy and touching you in adoration. She looks so deranged and horny. You start to fuck her faster.

"I cannot have this!" She says. "I'm a Barton! I cannot be demeaned in this way. Get off of me! I-I command you!"

"You... You d-don't have that power a-anymore" It doesn't sound convincing, but it is what you manage to say. She is still much stronger than you, she could get away from this with ease... but she doesn't want to.

"YES. I'm powerless..." She says. She tries to go back to roleplaying. "Move away, y-you d-dirty peasant! You are not worthy of having me! I'm... godthatfeltsogood... I'm... FUCK... I'm so FUCKING HORNY... I'm... I'm..."

"You are m-mine?"

"Don't ask it!"

"You are... mine!"

"Yes, YES... Kiss me!" You lower yourself enough to obey that order, she receives your lips with abandon. Her hands caress your cheeks, everything about her screams pleasure and need. "Are you... close to...?"

"Yes... I think so..."

"I wan't you to ...use my mouth, ok? Stab me, like you do now, but in my mouth, ok? ...I-I want you to g-grab my head and **** m-me to eat it. Don't let me breathe."

"Won't it...?"

"I don't care!... Please."

A maid, in the end, has to obey his mistress. When you exit her, she opens her mouth as wide as she can, her tongue out and pouring... she seems so hungry, she needs it so bad. It's such a weird fetish for a woman to have, but you admit to be... intrigued. Her throat feels equally burning. There is a faint barrier in it, that makes you not go all the way in. She looks up to you, and for a second you see the old Amelia there, her old cruel look: she wants you to keep going. You hesitantly grab her head and push, her eyes become blank with pleasure and then there is a soft 'pop' and your cock goes all the way in. You start to cum with that sensation, filling her stomach directly, your balls are smashed against her chin, tears come down for her eyes but deep down, in the waters below, she cums too. She eats it all.

When you exit her, she gasp for air, ****, fighting to breathe again. Her face is still teary, her black hair a mess, but just below those deep eyes you see her smile, for the first time ever, you see her truly smile.

And she looks beautiful.
