Playing the part of someone else's sibling always felt a little strange to Y/N, mainly because he had an older sister. And this was only the third time he took this role too, so some anxiety was present when he went over the dialogue he and his co-star of the day would have. Y/N heard of her before, but as soon as Athena Faris stood right in front of him, he was slightly shocked.

She was a really pretty, young woman and her voice sounded so enticing and seductive that it was hard to ignore her.

Athena:" You really look like you could be my step-brother, you know?"

Y/N:" I'll take that as a compliment. Are you ready for everything?"

Athena:" I am. I went over the script a few times to memorize everything we're going to do. And...don't go soft when we do anal~."

Giggling and winking at Y/N, Athena soon got into her spot while Y/N took a seat in the recliner. He did feel nervous, but was also excited to see where all of this was going. Flipping through the different TV channels, he sighed after a few minutes and just leaned back with his eyes closed. A few feet away, the clicks of a pair of heels could be heard with every step as Athena walked towards the living room. She had her purse with her which meant she would be going out for some reason. When she noticed Y/N, she immediatly went over.

Athena:" Hey, step-bro."

Y/N:" Athena, hey. What's up?"

Athena:" Well, I'm going out with a few friends in an hour. We're just hanging out,at the mall, so nothing big, buuut...I got a favor to ask."

Y/N:" You're running low on cash?"

Athena:" Unfortunately. And I know I asked you many times before, but I swear I will give it back as soon as I can."

Y/N:" I understand you're in a pinch, but money isn't just here to waste. Do you have anything specific you wanna buy?"

Athena:" A new swimsuit. It's 50$, but I only have 30. Please Y/N, could I borrow 20 from you?"

Athena looked right at Y/N with pleading eyes and her hands put together, quite literally begging him for the money. Eventhough this happened quite often, there was just something about her that made Y/N give in as he sighed and reached into his pocket for the money. He fished it out and held it in front of Athena, but he wasn't just going to hand it over. Instead, he had a demand.

Y/N:" Before I give you the money, I want you to fullfil your part of the deal."

Athena:" What do you mean?"

Y/N:" You said you wanna give something back, right? Then get to it."

Y/N emphasized his point by pointing right at his crotch at which Athena just stared for a moment, her eyes wide. This was her step-brother, they couldn't just do this. So in a quick turn, she was just about to leave with the money, but Y/N followed right behind her, trapping Athena against the door.

Y/N:" Now where do you think you're going, sis?"

Athena:" Y/N, this is wrong. What about mom and dad?"

Y/N:" They don't have to know."

Athena:  But you're part of my family. We can't do this."

Y/N:" It could be our dirty little secret. Also don't lie, I know you checked me out every now and then."

Athena only bit her lower lip and looked aside in shame as Y/N caught her redhanded. Truth be told, she did check him out whenever he was in the pool, did yard work or whatever. Thanks to the plot, she also masturbated while thinking about Y/N before.

Athena:" I admit I've had thoughts like that about you."

Y/N:" See? Then why not have some fun?"

Athena:" You're a tough nut to crack, step-bro."

Y/N:" Love you too, sis."

After the kiss on the cheek and laughing for a moment, both of them were now ready and willing to go through with it. Athena stripped off her top and jeans, but kept the heels on while Y/N just got completely naked. He grinned and followed Athena to the kitchen counter where she bent over and smiled at him.

Athena:" Ready when you are."

Y/N:" I was born ready."

Athena:" Then show your step-sis a little love."

And that was exactly what he did, kneeling down right behind the pale girl and spreading her cheeks. Y/N smirked at how clean and spotless Athena kept herself, so it was even nicer for his tongue to dig in. Licking from bottom to the top while massaging her ass was a nice warm-up and by the looks of things, Athena wasn't exactly against it as she pushed back a bit to have Y/N's face really deep in there. Both of them were now attached to each other with Y/N's tongue slowly progressing deeper, causing a little shudder to shoot through tge light brunette.

Athena:" Mmm that's lovely, bro. I didn't know your tongue could do this."

Y/N:" Secret talents, let's say that."

Athena:" Hehe keep going. I like it."

Y/N nodded and did as he was asked to, now pushing his tongue into her ass and moving it in and out of her hole.

It surprised Athena a lot, but she didn't mind it very much. She just shook her ass to give Y/N something back for his efforts. It wasn't that much, but it served its purpose nonetheless. They moved in a slow, but steady rhythm with each other and within just a few minutes, Y/N built up enough saliva to keep Athena's asshole wet, but also to lube up his hard cock, so he got up, rubbed it in to be ready and then proceeded guiding his member into her tight caverns.

Athena:" Oh fuck, Y/N. I didn't know you're that big."

Y/N:" You did, but don't wanna admit it. Last time I got out of the shower, I knew you peeked in a few minutes before."

Athena:" What am I supposed to do with a hunk like you running around the house?"

That was confirmation enough that Athena thought Y/N was attractive, so he just grinned before actually starting to thrust into her ass. He started things slow, but would move on to something rough later on. Athena moaned softly from feeling her ass being stretched by this big cock while it slammed into her over and over again. There was no turning back anymore and judging by them going at it, they would need a good while anyways. Y/N held on to Athena's hips as he crashed into her repeatedly, her cheeks rippling like crazy and her moans sounding like music to his ears. Maybe Y/N should've done this way earlier or do it again when another opportunity would open up, because by the looks of things, Athena couldn't get enough of this deep, hard pounding.

They initiated a deep kiss as well to add to the pleasure and the 'forbidden fruit' element of this scenario. But it was as Athena said with Y/N giving her some love and she appreciated it immensely. Throughout the kiss alone, Y/N already took everything up a notch as he thrusted into her vigorously with high velocity and speed as well. He literally clapped her cheeks so to speak as Athena moaned louder and more intensely. She was all hot and bothered over her entire body now for the day and she trusted Y/N to handle everything as well as he could.

Athena:" Fuck, Y/N. This is so good."

Y/N:" Hopefully you'll like everything else too."

This got Athena excited to see what he had in store while she kept herself pressed up against Y/N, so his dick could slip in balls deep. She felt every inch moving inside her, but didn't want things to stop yet. Y/N helped by maneuvering her over to the recliner with her ass now up and her face down. With every thrust and throb, Y/N was getting even more ready to shoot his load into Athena. The goosebumps came too as Athena begged Y/N to just let it go when he felt the time was right, so he went with deep strokes to hit as far as he was able to reach before he filled her anal caverns with a wave of his love juice.

Y/N:" Ohhh fuck!"

Athena:" Mmm it's right in there now, step-bro."

Y/N:" You've got such a tight ass after all, ut was hard to hold it in any longer."

Athena:" Hehe maybe I'll let you do it again when I'm back. And I swear you'll love my new swimsuit."

Y/N chuckled to himself and pulled out with the camera getting a shot of Athena's cumfilled hole before the two grabbed a drink and sat down to relax. It was a fun shoot for sure, so if there was an opportunity to do this again, they definitly wouldn't hesitate any time soon.
