Mason resists temptation

Meanwhile at Mason’s Apartment:

Mason and Serena had just finished eating the free pizzas that had landed in their lap. The boxes sat open on the table, mostly empty now. Mason leaned back on the couch for a moment, full and trying to collect his thoughts. He looked up from his empty plate only to get an eyeful of Serena’s cleavage. She had bent down to take his plate and the loose neck of her top hung forward, giving him a direct view down between her massive tits.

“Please give me your plate Master. I shall wash the dishes and put away the food I was preparing,” she said calmly.

Dragging his eyes off the deep valley of her cleavage, Mason handed her the plate. He got up and walked away from her, putting some distance between them. There was no point in arguing with this thing they’d turned his sister into. She clearly had an innate need to make herself ‘useful’. It was better that happened with these small things over it happening with the sexual thoughts her seductive and submissive body language was forcing him to have, he thought to himself.

He looked over at her as he watched her standing at the sink, washing the dishes diligently. Her back was to him, the baggy shorts riding up slightly as she worked. His eyes went down to her wonderful ass. The fabric stretched tight across her round cheeks. She looked so vulnerable standing there. He knew that she wouldn’t mind it one bit if he walked over and spanked her ass hard. Heck, she might lean into it and ask for another. The thought made his cock hard instantly.

“Fuck! I need to jack off to clear my head for once.”

But then a darker thought came to his mind. Why should he jack off when he had what was essentially a living breathing fuckdoll right here in his apartment? Serena would let him do anything. She would thank him for it. She would call him Master and spread her legs or bend over without any hesitation. The programming had turned his big sister into the perfect obedient toy.

Mason slapped himself hard on the cheek to get the thought out of his head. The sharp sting helped for a second. But as he looked at Serena’s ass again it looked too plump to ignore. The way it moved slightly while she scrubbed a plate was hypnotic. He found his feet taking him closer and closer without meaning to. Before long he was right behind her. He could feel the heat emanating from her body. The faint smell of her sweat from earlier mixed with the dish soap.

With shivering hands he reached out and grabbed her ass. His palms cupped both cheeks through the shorts. Her ass felt so plump, so good in his hands. Soft but firm at the same time. Serena seemed to jump slightly at the sudden touch but soon leaned back into it, pushing her ass against his palms. She smiled as she saw her Master finally taking interest in her.

Feeling emboldened, Mason slid his hands up under her top. His fingers moved over her smooth stomach and kept going until he reached her massive breasts. He grabbed them fully, squeezing the heavy flesh. The sensation of squeezing her perfect breasts was better than any kind of euphoric pleasure Mason had ever experienced. They were so soft yet so full, overflowing in his hands. Her nipples hardened instantly against his palms. He kneaded them roughly, thumbs brushing over the stiff peaks as he pressed his body against her back.

Serena let out a soft, pleased sound and pushed her ass back against his hard cock. She kept washing the dishes like nothing was happening, even as her Master groped her tits from behind. The contrast made it even hotter for Mason. His cock was throbbing painfully against her. He squeezed harder, rolling her nipples between his fingers, breathing fast against her neck.

This was wrong. So fucking wrong. She was his sister. But she felt so good. So available. So completely his. The guilt was there, but the lust was stronger right now. He pinched her nipples harder, making her moan softly while she continued cleaning the plate in her hands.

Mason’s hips started moving on their own, grinding his hard cock against her ass through their clothes. He wanted more. He wanted to pull her shorts down and fuck her right there against the sink. He wanted to hear her call him the best brother in the world while he used her body.

He was so lost in the feeling of her massive tits in his hands that he almost didn’t hear the sound of his front door being broken in. The loud crack of wood splintering didn’t register at all. Neither did the sound of the two female officers walking quickly toward the kitchen, boots loud on the floor.

Only when they pointed their guns and flashlights directly at him did he turn around and snap back to the real world.
