Seducing Jamie in a taboo threesome

After a morning enjoying intimately acquainting yourself with your new half-sister, and then a steamy shower and finally you talk over breakfast.

“So what did you mean when you spoke about tempting me with more last night?” You eventually ask, having mulled over wether to ask directly or wait for Tanya to surprise you.

“Well,” Tanya begins with a wry smile and a laugh before pausing for a few seconds, while she picked her next words. “When I asked you if you ever fantisised about Jamie and you said yes, was that true or just you saying anything to let me make you cum?” Tanya asks, fixing you with her sparkling blue eyes.

You hesitate for a moment biting your bottom lip and shuffling nervously in your seat before finally answering. “I used to spy on Jamie when I thought he might be jerking off,” You eventually confess.

“Not unheard of, but I though it was the brother than normally spied on the sister,” Tanya replies with a smile, before gesturing for you to go on.

“Well it was years ago, I was curious, and he was acting weirder and weirder around me and spending more time alone, so I decided to find out what he was doing,” You reply with a nervous laugh.

“So you caught him getting some solid practice on the old skin flute,” Tanya replies with another grin.

“Yeah, At first I was shocked and surprised, and I left quickly, but the more I thought about it, the more curiosity got me,” You continue.

“So I’m guessing curiosity grew to more than just watching Jamie,”

“Yeah, eventually I read up on it, and started rubbing myself while watching, and well as I researched more, I began to imagine doing the same stuff, and well Jamie was the only guy I had seen naked at that point,” You finally explain.

“So since then you’ve always gotten that warm tingly feeling when Jamie’s around?” Tanya asks a hint of hope in her tone.

“Yeah, honestly the number of times I’ve lied to girls at school about him being available is kinda embarrassing,” You admit.

“Wouldn’t want to see him with the wrong girl?” Tanya asks with a knowing smile.

“Something like that,” You concur after thinking on it for a moment.

“I’m guessing you’ve got the perfect girl in mind,” Tanya says with a grin.

“Kinda messed up isn’t it,” You say with an embarrassed laugh.

“I dunno, it’s kinda sweet in it’s own right,” Tanya says with a grin. “No one good enough for Jamie but you,”

“So I think that answers your question, what about mine?” You ask wanting to move the conversation away from all the feelings of embarsement and awkwardness.

“Well I thought you’d be able to work out what I was angling at,” Tanya replies with a grin.

“Jamie?” You ask almost hesitantly

“Yup, although only if you think I’d be good enough to share him with,” Tanya replies in a sultry tone, getting to her feet and making her way towards you.

“I dunno Tanya,” You reply as a feeling of unease begins to form in your stomach.

“Trust me, It’ll be so worth it,” Tanya coo’s in your ear.

“Alright, lets say I agree to this, what would your plan be? I don’t know he thinks of me the same way,” You reply, Tanya’s arms roam their way up and down your body.

“Oh don’t worry, I’ve got a couple of super hot outfits in mind, and then we just need to lure Jamie in and make his cock do all the thinking,” Tanya replies as her hands snake their way down between your legs.
