Anyone want to finish a sister cuckold story? Prompt

(I wrote this this morning, but got a little bored, because I knew where I was going to take it. Thats my problem with writing erotica, I can’t really surprise myself. So, if you’re wanting to write a cuckoldish story, but don’t know where to start, here you go. My only request is that you send me what you wrote once you’re done. Even if you don’t finish it send it my way, and maybe I’ll carry on from there)

Mark sat in bed, awaiting the annoying sound of his alarm clock. He always woke up before it, and liked to spend that time laying in bed thinking, but today he was just anxious. This particular morning he was thinking about rent. Mark didn’t know how he was going to pay it. He’d had some car troubles earlier that month that required a lot money. And seeing as his car was his living, it was unavoidable.

Mark heard a door close and footsteps across the living room to the kitchen.

A twinge of guilt ran through him as he heard those footsteps that were no doubt headed towards the coffee maker.

Those footsteps belonged to Marks sister, Mellissa. They were always close growing up, and moved in together after moving out of their parents place. They got along well, and cleaned up after themselves. Mellissa was a great room mate.

The only problem with this living situation was that the walls were really thin and so you could hear everything, as Mark discovered when he heard a strange buzzing noise one night. He had listened to it for nearly ten minutes before getting out of bed. In his naivety, he knocked on Mellissas door, and opened it.

“Mark, what the hell?!” Mellissa had yelled. She was sitting up in bed, and had pulled the covers up when she heard the knock.

“Sorry,” Mark said, not realizing how inappropriate that was. It was just Mellissa, he thought. He always barged in when they were kids. “But can you hear that?”

“Hear what?” She asked, slightly out of breath.

Mark listened.

“Its gone. There was this buzzing, you didn’t hear it?”

Mellissa went crimson and stuttered, and finally something clicked in Marks brain.

“Oh.” He said, quickly closing the door and heading back to his room. “Ew.” And he had put his headphones on and cranked them.

Mark always blocked out any acknowledgment that Mellissa had a sexuality. She never dated in high school, and even now she was just focused on her studies.

Thats not to say that she didn’t have opportunities. Mellissa was a beautiful girl, who developed early. Even at 14 she had large breasts that attracted the attention of all the boys, and Mark hated it. From then on he was always protective of her and made sure to look out for her and stop all the creeps from getting their pervy little hands anywhere near her body. And amazingly, he succeeded. Her virginity was intact and she had a pretty good radar for assholes.

But that sort of brings us to Marks current financial situation. Mellissa was a nursing student, and didn’t have much time to work. She had initially refused to move in with Mark, knowing that she couldn’t afford it. But Mark, being the naive fool he is, told her not to worry about it, that the rent was cheap and he could cover them both (which was true, up until now). Mellissa refused plenty of times, but eventually her big brother assured her and he had never let her down before.

Now none of this would be a big problem if their landlord, Dean, wasn’t such and asshole. He was constantly on everyone for everything, seemingly determined to make all his tenants anxious around him. It also didn’t help that he was a real creep, not bothering to hide his affection for Mellissa, even in front of Mark. The first time Dean had seen her (which was the day they moved in), he said to Mark “Fuck me. Tell you what, you get me a pair of your girls dirty panties, and I’ll knock off a hundred bucks.” What an asshole. Mellissa hated and avoided him, and Mark limited their interactions as much as possible.

Beep. Beep. Beep.

Mark sighed and turned off his alarm, before prying himself out of bed. He knew Dean would be in his ear sometime that day, and he felt an uneasy feeling in his stomach. He got dressed and headed out to the kitchen, to where Mellissa was making breakfast.

“Good morning.” She said, brightly.

“Morning.” Mark replied, grabbing some bacon.

“Anything special happening today?” Mellissa asked.

“Nope.” Mark said simply. “Same old same old. You?”

“Thats what I’m trying to figure out.” Mellissa sighed. “Its the same stuff everyday- I like it, don’t get me wrong, but… I think I’ll try to do something new today, something different.”

“Like what?”

“Not sure, but I’ll think of something.” Mellissa said, putting eggs on a plate for Mark.

Thats what’s great about Mellissa, thought Mark. If she feels shes in a rut, she looks for something new instead of just bitching about it. She prefers smiling to frowning, and doesn’t let shit ruin her days. Thats why Mark likes having her around, because shes this shining light that brightens his days.

Knock knock knock.

Mark immediately lost his appetite knowing exactly who was at the door.

“I’ll get it.” He said, glancing at his sister.

Mark walked over to the door, took a deep breath and opened it.

Standing on the other side was a wiry middle aged man, with short brown hair, wearing a wifebeater, jeans, and a cocky smirk you just want to slap off his face.

“Hey, Dean.” Mark said.

“Wheres the rent, Mark?” Dean replied, still wearing that irritating grin.

Mark moved forward and closed the door a little, trying to make sure Mellissa couldn’t hear.

“I-I don’t have it right now, but if you could just give me a couple mo-“

“Kid,” Dean interrupted. “why would I do that? This is a simple process: you stay here, you pay rent on the first.”

“But De-“

“When?”

Mark looked down at his feet to compose himself.

“On the first.”

“Holy shit, you do listen.” Dean called out, not bothering to keep his voice down. “So if you know its supposed to be in by the first, but don’t have it by the first, that leaves two options. Either you’re a crook trying to weasel his way out of paying.”

“Dean, its nothing like th-“

“Or you’re a loser. So which is it, huh?”

Marks body tensed as he struggled not to hit his asshole landlord. He looked up into Dean’s eyes, and tried to soften his expression.

“Dean-“

“I asked you a question. First you cant pay rent, and now you can’t answer a simple question?”

“I’m not a crook, and I’m not a loser, I just had some things come up that I had to take care of. I promise, I’ll have it soon, ok?”

“Fuckin loser.” Dean said, before he walked away.

Mark stopped himself from slamming the door, and closed it.

“Fuck.” Mark muttered under his breath.

“You can’t afford rent?” Mellissa asked. She wasn’t judging Mark, but he still felt guilty.

“…No. The car repairs kinda fucked me. But don’t worry, I’ll deal with it. I’ll have it soon.”

Mark grabbed his jacket and his keys, wondering where he was going to get the money.

“Mark, I can-“

“You don’t have to do anything, ok? I’ll take care of it. Thanks for breakfast, but I gotta go.”

And with that he left for the day.
