What's next?
Your First Full Day Together
(I'm going to speed time up a bit to move this along. I hope you guys don't feel too short changed. There may be a time skip soon as well. FYI.)
The rest of your day, your first day as your big sister's pretty boy, is simultaneously wonderful and mildly frustrating. Mostly the former. She pampered you for another hour, having you rest your head on her lap as she played with your hair the pair of you watched some television. This part of course was wonderful. The challenging part came later. When you asked Fiona about what you had found on her phone. When you asked her about her "clients". All you got was...
"Don't you worry your pretty little head about my business my love." And that was that.
You knew frustrations like these would inevitable as you trained yourself to give up control and become your sister's boy. And yet...somehow it didn't bother you for long. You were hers and that's all that truly mattered.
From one of the bags Fiona produces some extra clothes she picked up from the truck stop. T shirts, hoodies, socks, and even sweat pants had been purchased. The style was all American flags and big rigs and bald eagles but what she had gotten you fit quite well. The pair of you get dressed up to go out. With her ragged hair and truck stop attire your sister looked like poor white trash, but for you it tarnished her brilliance not one iota. She was weirdly sexy in a redneck sorta way.
As you leave Fiona pays for another few nights. She wrestled with the idea of moving to a nicer place but decided this place was a nice little hide away from the rest of the world. There isn't even a conversation as you approach the car, Fiona had the keys and was going to drive. That day you both get your hair cut. Fiona opts for a bob, sort of a Taylor Swift look circa 2016, and she gets you the pixie cut she mentioned. You both look ten times better walking out forty five minutes later. Two young, sexy, and vibrant people head over heels in love.
It was so fucking FUN being out with your sister. She took charge of every situation. You never had to worry about a thing. She didn't ignore you but neither did she consult you. She didn't bother you with questions or ask your opinions about things. She made sure you were looked after but did exactly what she wanted to do with you along the ride. It was strangely liberating and oh so very comfortable. Your little beta heart was singing with happiness.
And was she ever proud of being seen with you! She walked with power and confidence and overflowing pride at having you on her arm. Exactly as she had said she would she showed you off like purebred show dog. Pleased as she could be to have you at her side. All of the closed off feelings and unhealthy secrets that plagued your family seemed a distant memory. She would kiss you, passionately, in public. She would stroke your arm with transparent lust and shoot you flirty and nasty little comments and STILL call you her brother. She didn't exactly advertise your relation to each other but she did nothing to hide it either.
Fiona simply did not give a FUCK! She loved you and she wanted the world to know!
As the day went on you gradually became more and more submissive to her both in word and in body language. At first you tried to keep up appearances but Fiona just had a way of making you feel safe, she gave you the confidence to be your true sissy self. By the end you were giggling and blushing and being as coy as virginal school girl. Each time you gave in to your true nature she would reward you with encouraging words or a warm look or a long sisterly hug and kiss. She would intercept rude comments before they arrived or turn your head away from the judging eyes of others to gaze into you with hazel colored pride.
You were so god damned happy you could barely contain yourself. You'd never felt this way before. Ever. It was...powerful. Even as you submitted to your sister in a way no self respecting "real" man ever would you could feel yourself grow on the inside. There was raw power and honesty to what was happening to you and you had your sister to thank for it.
"I love you Fiona." You would say at random times.
She would always treat you with a ruby lipped smile. "I know my love. I love you too."
Did you get strange looks? Oh hell yes. At first you were self-conscious and ashamed, but Fiona's impenetrable self-assurance and sphere of shielding indomitable energy soon began to wear off on you. The longer you were with her the less you cared what others thought. She was a **** of nature and you felt like a little sailboat nestled safely in the eye of her storm.
You enjoy a good meal out which was an experience in itself. She lead you in as proud as a peacock, held your chair for you like a gentleman would a fine lady, and then without prompt ordered for you. Along with this came your next bit of frustration. You wanted the burger and fries along with a cola, but instead she ordered you the salmon with a salad. It was delicious, but the steak, potato and grilled veg on her plate looked a lot better. For just a moment you felt a twinge of bitterness but as you spoke with her you come to realize that it wasn't done out of spite or pettiness. It wasn't even a dom-sub thing, like she wanted better than you. It was actually a practical matter. She wanted you slender and sexy, but also healthy. Exercise had to be limited to avoid you getting too big, so that meant diet had to be controlled to keep you trim. Once this realization is made you feel far better about it. When she said she was going to look after you she wasn't kidding.
Fiona allowed you to speak freely as you ate. Together you joked and laughed like any young couple in love, but with the added dimension of a lifetime of shared memories. Fiona's eyes shone as she talked with you about your future life together. The conversation over the meal was exciting and exhilarating and you found yourself looking forward to apartment shopping with her. You would miss El and your Mom but you would be sure to visit them from time to time.
After the meal the pair of you take a short walk, where you stop to make out for bit in a hidden little corner, and do a bit more shopping before returning to the Motel at the edge of town. When you return the pair of you go to get an extra room key. Much to your amusement she puts the asshole attendant that had given you such problems the night before firmly in his place. He was simply no match for her. You give him a smug smile as you follow her back out the door.
The closer you got to your room the more affectionate and handsy your sister became. She was hungry for you and you were ready to be devoured. You remember her promise to "do something fun tonight". As you stand and watch her unlock the door to your room you had a feeling the fun was close at hand.
What's next?
