Swallow Your Cum To Impress Me – A CEI Story

All characters are of legal age

When you find out your stepsister is a slutty brat with a strap on collection, it can change the dynamics of your relationship.

Ethan had known his sister was bossy, annoying and competitive. But two weeks ago she’d fucked his ass on the garage floor with a huge plastic cock. He couldn’t stop thinking about it.

His thoughts constantly returned to the way her strap on felt before it pushed inside him. It nudged against his asshole, waiting for his body to accept it. The feeling of fullness, and submission and the way she teased him almost the whole way through was too much of a turn on to leave his head for more than a few hours.

He’d lost a game of darts and got fucked like a girl until he came. And now he was in love with her, or at least painfully obsessed.

What was worse was that she seemed to know how obsessed he was. She’d give him this devilish half smile. A look that said “I fucked you in the most degrading way possible. And it made you cum.”

Sitting alone in front of his computer, thinking about his stepsister and what she did had made him hard. Again. He would need to cum before he could think straight. Taking out his cock and giving it a stroke, Ethan booted up Pornhub.

“What are you doing little bro?” Emma appeared in the doorway like a fucking ninja.

“Oh God, get lost I’m busy!”

“Yeah, I can see that. That’s quite the hard-on you’ve got there. Were you thinking about anything in particular?”

“Why are you such a creep? Go away.”

“I just want to know what you were thinking about.”

“In case you didn’t know, guys get boners all the time for no reason.”

“I bet I know what you were thinking about.” Emma laughed. “I bet it had something to do with being on all fours, and getting so totally fucked you spunked all over our garage. And then you collapsed and laid in it for a while.”

“Why are you so obsessed with that? It’s really gross, you took it too far. You’re my stepsister.”

“But you look so cute like that. With your ass in the air and your cock all hard. I want to do it again. Do you want to do it again?”

Ethan’s cock was still rock hard and his stepsister’s voice was making him want her so much.

“Emma, I lost a bet. But I don’t want to be fooling around with you. It’ll be all kinds of trouble. Our parents will kill us for one thing.”

Emma laughed.

“I don’t want to fool around with you either. But I do think it would be okay to have just one kiss. A kiss might release some of the tension between us. Do you think that would help?”

“Just one kiss and then you’ll go away?”

“Yeah.”

“Okay then. One kiss.”

“Cool. Get your cock out. I want to see it.”

“You said one kiss!”

“You’re really hard little bro. I want to see it. Let me see how hard you are and then we’ll kiss.”

This was the moment Ethan should have told his stepsister to leave. But instead, he pulled his pants down and let Emma see his extremely hard cock.

“You’re leaking precum. Wow. All this for a little kiss?”

“I hate you.”

“No you don’t. Stroke your cock for me.”

“I’m not doing that.”

Emma slowly reached down and wrapped her fingers around her stepbrother’s shaft. She used almost no grip, gently stroking his dick up and down.

“It’s okay. I don’t mind stroking it for you. Were you thinking about what we did?”

“I wasn’t.”

“Yes you were. I can tell. You’re extremely submissive. But you can’t let go of pretending to be this aggressive dominant man. You don’t fool me.”

Ethan gasped. Her hand felt incredible. She was so gentle. Like she wanted to keep him on edge and hard as long as possible.

“I think what you really want is to be controlled. You’ve got such a hard on for me it’s killing you. Stop fighting it. You can admit that you’re obsessed with me.”

“I’m really not.”

Emma grinned at him, still stroking his cock softly up and down.

“You already know you’re not the first submissive man in my life. You’re not even the only submissive man in my life right now. I bet you’d love to know what I’m doing on my computer when no one is watching.”

Ethan’s cock twitched. The thought of his stepsister dominating other men was such a turn on. He had guessed early on Emma had a slutty side and he hadn’t really cared.

“It always amazes me how many men are really submissive. It seems like every man wants to be dominant until he gets the chance to be something else. You know you’re going to eat your cum for me, right?”

“I’m … what?”

“You’re going to cum into your hand and then you’re going to lick it up. Then I’ll kiss you. Just to release the tension.”

“Emma, please.”

“Tell me you haven’t tasted your cum before?”

Emma’s hand had tightened it’s grip. She was so close, and so warm. He could smell her scent, and hear her breathing.

“Of course you’ve tasted it. You most likely haven’t swallowed a full load, no one has asked you to. But you’ve probably dipped your finger in and had a little taste.”

Emma moves around and sat on his lap, the warm heat of her ass on his knees, her legs settle against his, holding her steady. She was gripping his cock much more tightly now, her rhythm was amazing. Ethan looked up at her and the same second realised he’s going to do anything she asks.

“Okay, good boy, you’re really close now. Put your hand here, you’re going to catch your cum when it happens okay?”

As Emma was explaining, she’d briefly stopped stroking and Ethan whined in frustration.

“It’s okay. You’ll get to swallow soon enough.”

Her fingers started working again.

“Here’s the truth little Bro. A part of you is probably eager right now to swallow the contents of your balls. But once you cum, you’re not going to want to do it. It’s going to feel like the worst idea in the world. But you want to kiss me, right? So no matter what you feel once you’ve poured out your milk, you need to swallow it for me. You’re not even going to think, okay?”

Ethan was trying hard to focus but all he could think about was his stepsister sat on his lap, working his hard cock. It was so wrong. She was so sexy, and so fucked up. And she was right, he wanted to swallow for her. How difficult could it be, a lot of women had swallowed his cum.

“This is going to be the second time you’re going to cum for your stepsister. I mean, I’m not sure the first time counts. I feel like I really took advantage of you. But it was worth it.”

She leaned in really close to whisper, his cock twitched, his legs tensed ready to cum.

“I still think about how gaped open I made you. I humiliated you, used you, and treated you like the loser you are. And you, you can’t stop thinking about how much that turned you on.”

Emma knew he would never be able to hold on to his load with her talking that way. She gripped harder as he came, thick heavy ropes of white cum on to his palm. She looked down at the mess.

“Oh wow. You might actually drown. Lick it up. But don’t swallow.”

It was said with such authority that Ethan acted immediately, his tongue lapping up the thick cum from his palm. He did as he was told. He didn’t swallow.

Emma took the moment to cuddle into him and push her whole tight body against his.

“Good boy. Don’t swallow. I want to keep you like this for a while. I know you agreed to swallow for me, and this is going to be a bit harder but I think you’re going to do okay at it. Right now, your body no longer needs to cum. You’re losing your sex drive by the second. And you’re going to realise that you’re a submissive guy, with his own load in his mouth. And you’re going to hate that.”

Ethan made a noise in protest. She was right. What the hell was he doing? His cum tasted terrible and was so thick and slimy in his mouth.

“Shh. Just a little bit longer.”

Ethan shook his head from side to side.

“No? But swallowing cum is so natural. Let me show you.”

She tilted her mouth open just under his lips and looked at him with big eyes that wanted nothing more than to have his cum in her mouth.

Ethan hesitated, and then drooled the cum from his mouth into his stepsister’s.

Emma looked at him, her eyes full of lust. A small drop of his cum dripped over her chin. She looked completely lewd and so perfect. Emma did not swallow. Ethan felt his cock getting stiff again. His stepsister was a fucked up nymphomaniac.

Her small hands reached out and wrapped around his throat firmly but not roughly, tilting his head backwards. He didn’t fight back. Her eyes looked at him like he was prey, stroking the side of his face. His mouth opened. Ethan knew.

He had promised to eat his cum, and there was no way he was getting out of it. The hot white seed was drooled into his mouth slowly. He felt it hit his tongue and slide to the back of his throat, where it began filling up.

The scent was bad but it was the texture made it a struggle. Thick, and sticky, not like any food, he fought an urge to gag.

She finished up, pouting her lips dangerously close to his.

“There you go. There’s a lot more for you to swallow now. I think you’ll be able to get it down in one go. The sooner you do it, the sooner it’s done.”

She grins sadistically.

“But once you swallow, I’ll know you’re a cum eating slut.”

Ethan closes his eyes and swallows heavily, trying not to think. The thick mess is swallowed down, leaving his mouth tasting of his spunk.

“Good boy.”

Her hands smoothly ran in to the hair at the back of his head and before he can think Emma had her lips pushed against her stepbrother. She kissed slowly, her lips moving on his, the taste of his own cum on her lips.

Ethan relaxed and Emma pushed her tongue in to his mouth like she intends to fuck him right there in his computer chair. She whimpered, her hips grinding against his hard cock.

“I want to fuck you right now. Get on my bed.” Ethan demanded.

“Nah. You’re my stepbrother. It would be weird.” Emma grinned and kissed his mouth casually making a mwah sound. She lifted her body off his.

“Are you serious?”

“Hey, don’t be getting annoyed at me. I just found out my stepbrother swallows his own cum. That’s not a nice thing for someone to find out about someone they consider to be family.”

“Are you trying to torture me?”

“Are you coming on to me?”

Ethan paused.

“No.”

“Good. You know, I kept the pegging to myself but I think people should know you swallow your own cum. I think it’s really funny. Everyone would get a kick out of it.”

Ethan felt a thrill of fear but more than that, he was beyond faking he didn’t want her.

“Okay. Emma, if you want to fuck, I want to fuck you. Just say the word. Any time. It’s weird, and I hate it, but I really want you. I’m obsessed. I can’t stop thinking about you.”

“I know.” She grins. “I don’t think I’m ever going to let you fuck me though. It would be too weird.”
