Domme Step Sister Shares Some Secrets – An Exposure Story

Ethan didn’t get a lot of time to himself, but this Friday night was going to be different.

Dad and Step Mum were out for date night, and wouldn’t be back until late. His brat sister Emma was going out to a party somewhere across town. Which left Ethan with time for Playstation, a takeaway pizza and a big bottle of Coke. And the whole house to himself.

He’d just settled down and booted up when he heard keys in the front door.

The disappointment was almost physical. Why couldn’t he get any peace or time to himself?

Then he heard girl-ish giggling from downstairs. He’d assumed his parents had got home early, but it sounded like Emma had bought someone home. Despite himself, Ethan felt his cock stirring. Was she downstairs with a boyfriend?

Quietly, he turned the telly off. His crush on Emma was still as big as it ever was, and he hated the idea of her bringing a guy home. None the less, it wasn’t like he was going to get any say in the matter. If she was downstairs with a man, he would just need to tolerate it like the beta submissive he was turning in to.

“Ethaaaan! Come down here!” Emma’s voice yelled up the stairs.

Ethan rolled his eyes. Okay. He was going to meet the new boyfriend. Great. But as he turned the corner in to the hall, he realised Emma had bought a female friend home.

“Oh, hi.” Ethan realised he was blushing. Why was he so obsessed with the idea of his Step Sister getting a boyfriend? It’s not like they were together or could tell anyone about the things they’d done together. And this was a friend. Just an innocent friend of his step sister. She’s probably come over to watch tele or something.

“Ethan tell Ashley about how I fucked you, she doesn’t believe me.”

Okay, not so innocent.

“Jesus Christ Emma, are you drunk?”

The new friend had big eyes and was shorter and much curvier than Emma. She looked like a pretty side kick to Emma’s stunning blonde dominance. She looked awkwardly at the floor, unable to keep a blushing grin off her face.

“I’m a bit drunk. But that doesn’t mean that what I’m saying is a lie.” His Step Sister put an arm around her friend and continued talking only to her.

“I fucked him in the ass with a strap on. Then I made him eat his own cum. And then I tied him up and just y’know… used him. Right here in this house.”

Ashley looked and Ethan and giggled uncontrollably. Okay. So they were both drunk.

“Emma you said you wouldn’t tell people.” He meant to say it with assertiveness, but it came out as childish whine.

“I have some really good photos of your penis and she hasn’t seen those. I’m a good Sister to you Ethan. Because I think Ashley would really like those photos. They’re good photos.”

Desire and embarrassment flooded Ethan’s stomach. His face blushed and despite himself, his cock was getting harder in his pants.

“Emma you’re being so mean to him.”

“Not really. He likes it. It makes him horny when I bully him. I bet he’s hard right now. Go and check.”

Both girls doubled over laughing.

“You’re an idiot Emma. If Mum and Dad find out you’ve got this drunk they’re going to be so angry.”

“Ooo, scary. Go and get us both a drink. I want a Coke. What are you having Ashley?”

The brunette looked unsure of herself.

“Is there lemonade?”

“Get Ashley a lemonade and me a Coke.”

Ethan paused, half tempted to go back to his Playstation and hide.

“Drinks. Now.” When Emma talked to him like that, it short circuited his brain. He felt possessed, like he was completely compelled to do as he was told. There was no space for his own thoughts.

He turned away to get the drinks. As he got the cans out of the fridge, his mind ran through what had just happened to him. Emma had told someone what they had done together. How many other people had she told? The idea made him feel sick. When he was with Emma, they were in their safe, messed up little play space. It was private, for just the two of them.

Of course, he’d always been fearful they might be caught. His big fear had been their parents catching them. But it had never occurred to him that Emma might tell someone just for the thrill of it. She was so dangerous.

Was it possible Emma was going to destroy his life? Why wasn’t she ashamed of herself? How was she so confident in the face of this fucked up game they were playing together? Being the girl who fucked her Step Brother surely wasn’t something she wanted the whole world to know. Was it?

Ethan cracked open the cans and placed the drinks on a tray, along with two of the best glasses. His cock was hard, making it difficult to move around easily. He wanted to impress Emma. That desire was probably never going away.

He walked in with the drink tray for the two girls and put it down on the coffee table.

“How many people have you told?” He asked

“Told what?” Emma fired back.

Ethan felt light headed, his whole body was hot, stressed, stimulated and turned on.

“That we fooled around.”

Emma suppressed another round of giggles.

“Is that what you’re calling it? Fooling around.” Emma produced her phone and held it up, showing a photo of Ethan’s hard cock and the word Pervert written in Sharpie on his skin. Ashley made an uncoordinated grab for the phone, knowing that there were secrets on there.

“Hey, let my Step Bro have at least one secret.” Emma laughed, keeping her phone out of reach. “It is a good dick though. I’m not going to lie.”

Ashley struggled for the phone, begging drunkenly to see it.

“Emma, you realise that this is going to go so badly for both of us. You’re my Step Sister, this isn’t something you want people to know. Are you crazy? If you’re telling people, it’s not just Mum and Dad who are going to find out. It’ll be the neighbours, all our friends. Do you want that? To be the girl who fucked her Brother for the rest of your life?”

The laughter died on Ashley’s lips, aware the mood in the room was changing.

“You’re a psycho. You’re going to ruin everything.”

“Wow, everyone needs to calm down here. This is no big deal. Ethan, rub Ashley’s feet now. You both need to relax, God.”

Ethan was ready to leave. The fear and anger was over riding his submission. And then, Emma got down on to the floor and pulled off one of Ashley’s little white socks and the feeling of desire aggressively surfaced again, blocking out all thought.

“That’s a good boy. On your knees now.” Emma cooed and Ethan couldn’t help himself, he was sinking down and putting the pretty feet in his hands. They were slightly warm and smaller than he’d seen before. The toe nails were painted a pretty pink colour.

Ethan began to rub, running his thumbs along the base of her foot, pressing each toe between his fingers. There really wasn’t anything that this feeling couldn’t over ride.

Emma picked up her phone and Ethan’s stomach, once again lurched. Everyone was going to know how disgusting he was. Not just someone who fucked his own Step Sister. But someone who submitted to her, someone who allowed her to dominate and humiliate him. Someone who did all this and then asked him to rub her friend’s feet.

He looked up at her, and felt the familiar lust. He hated it, but it was uncontrollable.

“Are you happy with yourself?” he asked.

“Are you?” she grinned back.

Ethan huffed, and continued to work on Ashley’s feet.

“Face it, you wanted this. You never asked me to delete those photos. You played games with me in places you knew we might get caught. Deep down, you wanted this experience.”

“You’re going to ruin my life.” Ethan said quietly.

Emma giggled.

“Yeah. Maybe. It is pretty disgusting. I really, really want to show Ashley this photo Ethan. And she wants to see it. Can you think about how it would feel, for my friend to see your cock right now, while you rub her feet?”

Lust and shame and desire and fear ran through Ethan in equal measure. The tension in the room was incredible. Ashley sighed happily and Ethan worked his fingers between her toes.

Emma turned her phone to Ethan again, letting him take in the image. His hard, leaking cock. The sharpie message, the zoned out look of desire on his face.

“Can I show her? It’s such a good photo.” Emma asked and Ethan knew he was fucked, totally owned by his Step Sister and there was no turning back now. There was nothing he wouldn’t let her do to him.

“…yes.”

Emma laughed again and Ashley took the phone excitedly.

“Didn’t I tell you he liked it?”

“It’s not as big as I thought it would be.” Ashley said

“I said it was a good dick, not a big dick.”

Ashley grinned.

“You’re such a slut Emma.”

Emma nodded.

“I like what I like”
