suck my dick? (OP version)

“Lisa? Do you want to suck my dick?”

His sister looked at him with confusion.

How could he ask that from her? She briefly thought. She only wanted him to look at her tits, didn’t she? No… She didn’t, she realized. She wanted to suck his dick. She NEEDED to suck his dick. Again she felt overwhelmed by this sense of newfound purpose.

“Oh my god! I do!” She exclaimed, dropping on her knees and unbuckling her brother’s belt to get his cock free of his pants.

Dan, shaking, grunted as her sister grabbed his manhood in her right hand and moved her lips around it. He felt the warm embrace of her mouth around his dick, and the twirling of her tongue around his shaft.

She did not seem pretty experienced, but damn was she showing enthusiasm!

Dan could not complain anyway, his level of arousal was more than enough to compensate his sister’s lack of skill.

He leaned his head back and closed his eyes, enjoying the situation. His sister was on her knees, naked, blowing him. This was heaven on Earth.

Lisa was enjoying it too, bobbing her head up and down. Since she was currently fulfilling her purpose, she was feeling very relaxed. Her head was clear now that any sense of urgency had disappeared.

A few thoughts crossed her mind, and she finally took the time to acknowledge them.

First of all, she mentally inspected her current situation. She was giving her own brother a blowjob. She had to admit it was highly unusual, especially for her, but she was at this very moment glad that Dan was such a pervert, since it made him a lot more compliant. She couldn’t even imagine what she’d have to do if he didn’t want her to suck his dick. She NEEDED to suck his dick. She was doing her best to make him enjoy it, as she suspected he’d be less tempted to let her suck his dick again if he didn’t. She didn’t really care about whether or not he liked it, but she was ready to do what needed to be done so she’d maximize her chances of sucking his cock as long and as much as possible.

After a couple minutes, Dan couldn’t hold it anymore.

“I’m gonna cum!” He mumbled.

He tried to move to get his penis out of her sister’s mouth. He wasn’t really thinking about it, but was used to his ex getting mad if he dared cum in her mouth.

Lisa grabbed him to stop him from pulling out, and looked at him with fierce eyes. He could feel it was a warning. It meant “Don’t you dare!”.

This was the last straw. Sperm jizzed out of his cock like never before in his life.

Lisa gagged, but did not even open her mouth. She swallowed as much as possible and just kept on sucking on his now flaccid penis.

“Wait…” He stuttered. “I’m done.”

His sister looked at him with obvious signs of distress.

She spoke while still holding his dick in her mouth.

“I can make you hard again. Please!” She begged.

Dan hesitated. He could indeed feel himself go hard again. Maybe he could just let her do it for a few more minutes, and then he’d give her a new purpose, so he could rest his tired prick.

Lisa, on the other hand, was trying to hide her panic. She had convinced him to let her suck him off a tiny bit longer, but she could tell he would try and get away at some point.

She NEEDED to suck his dick. She had to find a way to keep doing it, as much as possible.

She focused on the problem.

He was the problem. She needed his cooperation to get his cock in her mouth, and even though he was a pervert and seemed to enjoy it, he would definitely keep her away from his penis most of the time. He probably felt like he had other things to do than just stay with her a few inches from his crotch all day and night.

Did she need his cooperation, though? No, she realized, she didn’t. Maybe she could attach him, gag him. If he had **** then she’d be able to suck his dick for as long as she wanted.

She could feel her brother’s dick getting harder, she knew she only had a few more minutes before he would try to escape. She needed to find a solution, fast.

Taking him hostage was not viable in the long term, she thought. Her mother would come back and wonder what was going on. She’d look for him if she couldn’t find him. She wouldn’t be the only one looking if he vanished for too long. Police could get involved. The risk was too high. If she got arrested she would be stopped from sucking his dick, for a long time, if not forever.

Wait! She thought. She just needed his cock. Maybe she could cut it? She had her teeth around it, already.

No, she realized, it was a dumb idea. First of all, once severed, his dick would start to rot, and she’d soon find herself without anything to suck. Even if she managed to find a way to preserve it, police would surely get involved.

Seemed like she had **** but to try and convince him to let her suck on it as much as possible, and just wait patiently the rest of the time. She didn’t like this idea, but she probably had ****. Sucking his dick a few times a day was better than nothing.

Until he’d decide to leave, she was going to enjoy her last minutes with it in her mouth.

Dan cummed again soon after. To his surprise her sister did not try to stop him from moving away this time. He hoped it wasn’t a sign the effects of his power were finally wearing off.

“That was fun!” Lisa said with a cheerful smile. “We can do that any time you want.” She added with a sultry tone, licking her lips and looking intently at his now completely deflated dick.

Good, Dan thought, she still wanted it. Obviously she was thinking long term, just like when she was cleaning the house. She probably realized she couldn’t just do it non-stop.

“What the hell are you doing!” Shouted someone, behind them.

Dan recognized the voice of her mother, and turned around, shaking.

She was standing under the kitchen door frame, wearing her coat and with her keys in her left hand, a small bag of groceries in the other. She looked horrified at the view of her children, one naked and the other one with his cock out.

Fuck, he thought. He wasn’t expecting her this early.

He had to do something. Would his power work on her? Even so, what should he tell her?

“Mom...” Stuttered Lisa. “Let me explain! It’s not what you think!”

She was terrified at the idea that her mother would try and stop them from doing it in the future. She NEEDED to suck his dick again.

Dan opened his mouth, and said :

“Mom. You want....”
