One Down!

Turning to your little sister you see those big dark eyes looking at you with unmasked lust. Her right hand strokes the shaft of her cock through her thick cotton dress.

"El! What are you doing!? We just made the bet!" You exclaim.

She smiles. "I can't win against Fiona. I never win against her." She takes a breath, taking in a bit of confidence as she does so. "If I can't have you...at least I can serve you."

Fiona whispers from behind you. "That's right Elsie. You can serve Jesse. He'll be such a good master for you. Don't you think so?"

"Stop it." You snap at Fiona over your shoulder.

Leaning forward Elsie peels her t shirt up over her head. The impeccable pale skin of her stomach and chest and shoulders being exposed. "Would you help me with my bra?" She asks coyly.

"No! What are you doing? Stop this."

"Sorry, you're not my master yet Jesse. Soon...soon." She reaches behind her and unclasps her bra. Her simultaneously willful yet submissive gaze never wavers. She pulls her arms back through and allows her bra to fall from her two big firm perfect breasts. Your eyes nearly bug from your skull. Holy shit, your little sister had one hell of a rack on her! Gah! This was Elsie, stop ogling her tits!

"Elsie, come on. Don't do this. You could win this thing. And..." You hesitate. "...and we could...uh...be together...for a night."

She shakes her head. "No, I thought that's what I wanted but...I don't want it to happen like that. I don't want to **** you. I know you don't like me like that." Her plump lips turn down into a pout. "I know you don't want a freak like me Jesse. I'm sorry I'm so ugly in your eyes." You could see tears welling up.

"El...you're not a freak." Fiona says softly. "You are perfect. You are beautiful."

"We're freaks Fiona. Men don't want us. Jesse doesn't want us. He doesn't want me. He's got a nice girl like Allison. He deserves a nice girl like Allison." El takes a fortifying breath and blinks the tears from her eyes.

"Fuck Allison!" Fiona growls. "Let me take care of Allison."

"El, Fiona, stop this." You beg.

Elsie was wiggling her curvy hips out of her dress and panties. Her thick cock is the first thing to show itself followed by her big balls and smooth legs. She is filled with shame as you can't help but look at her resting penis, but she continues anyways.

"It's okay Jesse. Really. Just let me have this month. Let me be yours...even if you can't be mine. You don't have to treat me nice or anything. You don't have to...touch me or...be seen with me. Just let me serve you. Let me feel that at least."

You didn't know what to do or say. This was all coming at you so fast.

Elsie begins to slowly stroke herself. Fiona gets up from her chair and glides gracefully around to the other side of the couch. She settles down on the opposite side of Elsie.

"Do you want help?"

Elsie nods. "Thank you Fiona." She looks to you. "He doesn't understand."

"I know, but he will. Eventually." Fiona grins. It was a...warm sisterly loving grin. She wasn't smiling to mock her sister or to flaunt the fact it would soon be a one on one challenge to you. It had been a long time since you saw such a tender expression on your big sister's face.

Reaching down Fiona grasps Elsie's cock. El lets go, her right hand coming to rest on your thigh.

Fiona sidles right up against her little sister and begins to stroke her. As Elsie continues her longing soulful gaze at you, Fiona focuses on Elsie. She gives her a little kiss on the cheek.

Fiona begins to whisper. "He'll be a new master. You will have to have patience with him. He won't know what he is doing."

Elsie nods. "I know."

"He'll try to reject you."

"Guys! I'm sitting right here!" You say in disbelief.

"I'll be such a good **** for him." Elsie says, her cock beginning to harden in her sister's hand. "But if he doesn't want me...that's okay. I'll still be a good **** for him."

"Yes you will, I know you will." Fiona says with a strange sort of beaming pride. "Yes you will Elsie. I can see that now. I never realized you had this inside of you. What a special gift you have. Jesse will be so lucky to have you."

"Guys, come on! This isn't fair. You can't give up like this Elsie." You cry. "We're going to win the bet, remember? Elsie! I'm not going to be your master! Stop this. Stop it!"

"But...you said!" She looks at you with obvious pain.

"Shhhh..." Fiona kisses her again. "Don't listen to him. I told you, he'll try to reject you. But you won't let that stop you, will you Elsie?"

El is comforted by Fiona. "No, I won't."

"You'll be a good **** for your master, won't you honey?"

"Yes."

"You'll do anything for master, won't you Elsie?" Fiona grins, she was VERY much enjoying this side of her sister. She was looking at Elsie with a new found respect. Reverence might be a better term.

"Yes."

"He'll come around then. You just have to work hard and show him your worth. Don't worry."

"El, come on. It's me...Jesse. Your brother, your buddy, your best friend. I'm not your master."

An adorable flush now brightened her face. Her cock was expanding by the second. "Soon you will be...soon master. I'll be yours soon. Ohhhhh....that feels good Fiona."

Her big sister grins. "Good girl." Fiona looks at you and shakes her head. "You lucky...lucky...bastard. Men have died for slaves like her. Wars have been fought. I would have...god...I would have done anything for a **** like Elsie. Jesse, this is special. This is really special."

"Fiona, stop this. This isn't funny. Elsie isn't a ****. I don't want a ****!" This was madness. What kind of game were these two playing? "You take her! I don't want her!"

Elsie's face flinches as if you'd physically struck her.

Fiona glowers at you with burning anger. She wasn't playing at this, and neither was Elsie. "How can you be so cruel!? I can't take her, she's giving herself to YOU dummy! Oh my god, you have NO idea how big a deal this is."

Fiona was asking YOU how you could be so cruel? The woman that made fun of your penis and stamina every chance she got.

As her right hand continues to stroke Elsie's impressive hardening cock she uses her left to stroke El's short brown hair. "He doesn't understand yet. You are going to have to prove yourself. He won't accept you until you prove yourself."

El nods, seeming to understand. "I will. I will prove myself for my master."

"Elsie."

"Yes Fiona..ohhh..."

"Listen to me very carefully. To be a good **** you must obey your master without question. You must work hard for him. Think only of him. You must be honest with him at all times about all things. His will is your will. Your pleasure is second to his and your pleasure must be earned. His pleasure must be always attended to."

"That's it, I'm leaving." You get up. "This it too fucking weird. I should never have made this bet."

Fiona's rage filled eyes flit back to you. "Sit the FUCK down! You ingrate! This has NOTHING to do with the bet. This is WAY bigger than that. Jesus, how stupid are you? Can't you see what is happening here? SIT DOWN!"

By the sheer **** of Fiona's will you find yourself sitting down once more.

"You...just watch." She informs you. She turns back to her sister, her hand continuing its up and down motion. Her voice softens once more. "Is it feeling good Elsie?"

"Yeah." Elsie nods.

"He's handsome, isn't he?"

"Yeah." She gazes at you with unabashed love and desire.

"Are you willing to service your master however and whenever he desires?"

"Yes." Elsie's breath is picking up now. Her luscious pink lips parting to take in enough air.

"Guys. Elsie. Come on, you're going too far. You're freaking me out here."

"I'm sorry master. Soon, it will be over soon."

"When you cum you will be bound to him. He will be cruel. You must be ready."

"I'm ready."

You can't help it. Your eyes begin to run up and down her gorgeous body. She was more curvy than the lean athletic Allison. Her hips wider. Her breasts fuller, bigger, and rounder. Her nipples a bit wider and flatter, pinker than Allie's. Everything about her softer and more...inviting. She was simply stunning. Allison was no slouch in the looks department, but El...El was next level gorgeous. Many asked if she would model or act when she got older. But Elsie had no interest in such things. Her succulent body writhes in pleasure as her breathing picks up even more.

"Master is looking at me." Elsie gasps. "He's looking at my body. Ohhhhh! Thank youuuu."

You snap your head away, blushing in embarrassment.

Fiona chuckles. "Good girl. That's it. Your pleasure is for your master. Not for you."

"Master...master, please look at me. Please look at your ****." Elsie pleads.

"Shhhh." Fiona whispers. "Master does what master wishes. It is not your place to beg unless that is what your master wishes."

"Ohhh...sorry." Elsie moans.

"It's okay darlin, you'll learn. Your master will train you, when he is ready. You must be patient with him."

"I am NOT her master!" You insist. "I WON'T be her master!"

Fiona shakes her head in annoyance. "Are you trying to hurt Elsie you dumb fuck? God damn it! Have a fucking heart!"

"Fiona!" You object. "This isn't right. Something is wrong with her. This is fucked up!"

"There is nothing wrong with her! She's found her true self. Can't you see that!?" Fiona was incredulous at how blind you were.

"Fiona! Elsie!" You bark.

Fiona looked ready to lay into you but before a response could be made Elsie lets out a long soft groan. "Ohhhhhhhhh!"

Her balls tighten and her big cock pulses in Fiona's hand. Thick ropes of jizz spurt up between her breasts. Her back arches and her hips thrust. Her tits shimmy and jiggle as her body rocks and thrusts. Wad after wet creamy wad of cum erupts from her ten inch member.

"Ohhhhh yessss! Jesse!" She cries.

Fiona continues to stroke, looking at her sister with what can only be described as a deep loving pride. "Ohh my! So fast! You've never cum this quick before! Wow!"

"Ohhhhh master!" El moans. "Master!"

"No Elsie, no!" You protest.

With long firm squeezes Fiona milks her sister to the last drop.

Elsie is panting, her body shaking with excitement. "I did it! I'm his! I'm Jesse's!" She cries triumphantly.

Fiona nods, seemingly honored to be here for this moment. "Good girl." She kisses El's forehead and pets her hair one last time. "Good girl. I'm so proud of you."

Fiona pulls back her right hand, it was cummy mess. With her clean hand she slaps you on the shoulder. "Just me and you now champ. November just got a whole lot more interesting. May the best woman win." The month long wager was not even ten minutes old and it there was one down already! Fiona glances back to her glowing sister the back to you with an expression of open jealousy. "By god Jesse, you lucky...lucky...man... I can't even..." Her voice trails off.

Shaking her head she gets up to go wash her hand.

"Wait." You say, suddenly uncomfortable with the prospect of being alone with your little sister who was naked, covered in her own seed, and smiling at you so strangely.

Elsie lets out a happy moan. "Masssterrrrr."

"Fiona, wait. Help me..." You panic.

"Sorry Jesse, she's yours now. I gave her a primer, but she's in your hands now."

"What do I do?"

Your big sister looks back over her shoulder and laughs. "Use her dummy. Let her make you happy. Fuck..." Fiona shakes her head and continues out of the room. "...you have no clue about the treasure you've just received."

And with that she was gone. Leaving you alone...with your new ****.
