suck my dick

“...suck my dick?” Dan finishes his question and waits with baited breath, the sharp pang of guilt he feels overridden by his desire.

Lisa thought about it for a short moment. She knew that this, too, was immoral and that she would normally be enraged if anyone, let alone her brother, asked her something like Dan just had. Still, she quickly realized that it didn’t matter and that she absolutely needed to fulfill her new purpose: sucking Dan’s cock.

Lisa shook her head yes enthusiastically and took a step forward, then frantically tore at Dan’s pants.

“Woah,” he said, somewhat surprised as Lisa tore his pants down to his knees and freed his erect cock. His eyes lingered for a moment on Lisa’s exposed and jiggling boobs as she got on her knees.

Lisa saw his gaze and felt conflicted. She didn’t want him to look, but she needed to suck his cock right now. As she sank to her knees and wrapped a hand around his dick to maneuver it into her mouth, she covered her tits with her other arm and said, “Hey, don’t look at me like that.”

Dan inadvertently groaned as his arousal and pleasure spiked when Lisa wrapped her lips around his cock. He felt her mouth gloriously working on his cock, sucking for all it was worth. Despite himself, Dan thought about what just happened and realized that Lisa no longer wanted to reveal her tits and was uncomfortable. He also noted that her sucking was not a blowjob, but instead just her idly sucking on his dick with no real movement. Fully committed to what he was doing, Dan decided to test the extent of her manipulated desires and stepped back while pushing her head away.

Lisa’s eyes widened in alarm and she pushed against Dan’s arm on her forehead. Panicked, she shouted, “What are you doing? I have to do this! Please!”

“Look, I really appreciate what you’re doing, but I can’t really get into this, I’m sorry. Maybe if you tried to make it a bit more pleasurable for me and played with your tits I could though. I’d be down to give it another try.”

Lisa thought quickly, her mind racing. She considered forcing herself on him, but wasn’t sure how that would work long-term. She really didn’t want to do what he asked, but she finally decided to make the pragmatic choice for now and went all-in with it, saying, “Of course Dan, I’m sorry.”

Her hands started playing with her tits and she looked at Dan with a fake sultry expression. The extent to which she would go actually surprised him for a moment, but when he withdrew his hand she nearly dove forwards. Her lips yet again wrapped around his dick, and she felt the satisfaction she so craved.

Dan was in heaven. His fingers combed through Lisa’s hair as she dutifully worked his cock. This time, her mouth moved up and down his shaft as she sucked. Her tongue played with dick as her hands played with her tits. He watched them move in her hands, though it was hard to see, and felt himself approaching the edge.

“Fuck, I’m gonna cum,” he said between breaths.

Lisa didn’t acknowledge him. She was happy doing what she knew she should be doing, and if he came she hoped he would let her ease up on the sexual things she was doing.

Her head bobbed back and forth, and Dan realized she wasn’t backing off. The sensations playing along his cock built up as he watched her tits move and her head bob. Finally, he gasped, “I’m cumming,” expecting her to move off of home if only for a moment.

Although she didn’t want his cum in her mouth, Lisa knew that she would have to deal with it. There simply wasn’t a way for her to suck his cock without that occurring. She continued on, but stopped playing with her tits in the hopes that he wouldn’t care.

Dan didn’t notice. His dick throbbed in pleasure as he started to cum. He looked down, but Lisa was continuing to suck his cock as it throbbed repeatedly, shooting his pent-up sperm into her mouth. In seconds it was dribbling out of her mouth and falling on the floor.

Finally, Dan stopped cumming, his dick soft. Lisa, though, kept sucking on it, but she was now back to her casual method from before. He wasn’t sure how to feel, but he saw the cum falling from Lisa’s mouth and his cock twitched as he imagined something. With a fake smile, Dan said, “You want to swallow the cum I just gave you.”

Lisa’s purpose shifted yet again and she slowly moved her mouth off Dan’s cock, her lips tight so as to get as much cum off of it as she could. She swallowed, a smile on her face, and then started to scoop the cum from her face and tits to her mouth.

Dan watched, aroused yet regretful. He knew he had taken this too far, but the fantasies he had always had still tormented his mind. As Lisa went to her hands and knees, her tits swaying, in order to suck cum from the floor, Dan considered how he could have everything he had wanted. His newfound power could give him his wildest fantasies if he was careful, but he didn’t know what the consequences were.

With a sigh, he gave up thinking and watched his sister lap up the last bits of the cum. He thought it was a pretty hot scene given her position and her beautiful tits pulled by gravity towards the floor.

Eventually, Lisa got all of the cum off of herself and the floor and sat back. She looked around, the satisfaction she had felt melting away.

Dan saw Lisa’s smile fade, and wondered what would happen now that she had no more cum left to swallow. He braved himself, his body tensing as he imagined the enraged reaction she might have.

However, the anger never came. Lisa simply stared ahead, listless, and then laid on the floor, her body nearly limp. She started to cry softly, but she didn’t know why exactly. She thought that she should feel mad about what she had done, but knew that those things had all been a part of the purpose she had felt at the time. She thought she should want to do something, but nothing came to mind. She felt empty.

Concerned, Dan said, “Hey, you okay? What’s up?”

Although she didn’t feel any need to respond, Lisa simply said, “I don’t know what I want to do. There’s nothing I want. Nothing.”

Her shoulders shook on the floor, and Dan sat down next to her, thinking. He realized that he might have permanently altered her, but he didn’t know how. He clasped his hand in hers and said, “How can I help?”

“You can’t, it doesn’t matter. There’s just no reason to do anything.”

It struck Dan that she might only want to do whatever he tells her to want from now on. That thought scares him and fills him with guilt, but at the same time it makes him aroused.

He sat there with her for over half an hour, watching her slowly stop crying. He hoped that she would get up eventually, but if anything as the time went on she became more lifeless. Finally, he said, “You should get dinner.”

“I don’t care,” she replied calmly. “It doesn’t matter.”

After a sigh, Dan decided what to do next.
