Reprogramming The Neighbour

You noticed that a new girl moved into your building, so you decided to go round and welcome her to the neighborhood! The girl introduces herself as Fiona, and explains that she's moved here because she just split up with her ex girlfriend. You tell her that you recently went through a break up as well, and the two of you chat a little about your situation. You tell Fiona that you actually came round with the idea of giving her a welcome gift - you had bought this voucher for a spa day originally intending to gift it to your girlfriend for her birthday, but then she broke up with you before you could give it to her. You tell Fiona that you've tried looking into returning it, but it's not possible; so the voucher will just go to waste if she doesn't take it! Fiona is a bit reluctant at first, saying that she would feel bad accepting it, but you insist that you're happy for her to take it, and there's no chance of getting your money back anyway. Fiona then happily accepts it and thanks you for being so thoughtful, saying that she's sure she'll see you around the building, and will let you know how the spa trip went! A week or so later, Fiona knocks at your apartment door. When you answer it you're struck by how different she looks, and how she almost seems to be flirting with you.. But that can't be right, isn't she a lesbian? You invite her in and when you return from fetching her a beverage, you're amazed to find her lounging on your couch in just her underwear! Fiona laughs at how shocked you looked, and says it must be true that you really didn't know what kind of spa you were sending her to! You ask her to explain, and she tells you that the spa is a cover for converting women into obedient sluts and bimbos, and the women are either sold off to single men, or - as in her case - made to serve the man who sent them on the spa trip. So, even though you were unaware of the true nature of the spa, you're now her master and all she wants is to serve you with her body! She explains in detail how they influenced her and the other women, using techniques and mind altering substances to open their minds and replace their previous personalities with happy, mindless sluts. She begs to show you what she's learned but you're feeling very conflicted; you never meant for this to happen to her! Fiona insists that you shouldn't feel guilty, she's so much happier now; her every stress and worry has been taken away, and now she's just blissfully horny and desperate to submit to you! You allow her to pull down your jeans and take out your hard cock, and you watch in amazement as she begins to thoroughly worship your cock, telling you how happy you've made her. She begs for you to fuck her, reminding you that until the spa she had been a lesbian, so you'll be the first man inside her! She rides you passionately as you battle between your guilt and the incredible pleasure she's giving you, then you decide you can't hold back anymore and you flip her over to pound her in doggy, and then in missionary until she's desperately begging to be filled with your cum and made complete!
