First Time (Not What You Think ;-)

Lisa stretched her arms above her head, making her flimsy shift cling to her chest like a second skin. Liam gulped hard and tried not to stare.

Her teasing smirk stayed firmly in place. “You’re so easy to mess with, Liam. Honestly, it’s almost too much fun. Margot’s probably taking notes.”

“Can you please stop?” Her brother grumbled, crossing his arms as he sat up. “This house is already creepy enough without you making it worse.”

“Oh, come on. Admit it,” Lisa said, punching him on the arm. “You’re a little glad I’m here to keep you company. Imagine if you were alone right now. Particularly with this here ..." She deliberately nudged his all-too-visible hard-on, which was bulging against his boxer shorts. "Maybe I could ..."

"Don't you dare!" Liam clutched both hands over the suspicious area, but his flushed face betrayed him.

She laughed, rolling onto her back. “Relax, I’m just kidding. Mostly.”

Liam groaned and glared at her angrily. “You’re impossible.”

“And you’re no fun,” Lisa shot back, sticking out her tongue. Then she paused, her grin widening mischievously. ”Can I at least take another look up close? It was so dark in that hallway that I couldn't see any details. And you were done very quickly, by the way.”

She giggled and Liam's head turned redder than ever. He knew that they slithered down a forbidden path. He ought to say a definite and final No. But at the same time, a part of him wished that Lisa would actually do what she had hinted at. He was sorely tempted to give in. But then he realized: “It's Margot!” he called out loud.

For Lisa, this was THE opportunity to finally win over her brother. She rolled her eyes back and spoke in a hollow, rough voice: “Yes, I am Margot. And if you don't do what I want, I'll do unspeakably bad things to your sister.”

Liam was shocked and no longer knew what to do. When Lisa reached out and took hold of his penis, he flinched, but didn't pull away. She gave him a thorough feel. He moaned, torn between the growing arousal that these touches sparked in him and the sheer fear of what might happen next.

Lisa was still not satisfied. In her ghostly voice, she growled: “Take off your underpants.” And when he didn't immediately comply with this demand, she added: "Do it now! Otherwise your sister will have to pay for it.”

Startled, Liam did as she wished in a trice and shed his last piece of clothing. Lisa had to stifle a laugh. Oh, this was going to be fun! She was too familiar with her brother and knew exactly which of his buttons to push to get what she wanted. Curious, she crept closer and took a good look at everything. How had he done it before? Imitating his movements, she grasped his cock. Surprised, she realized how hard and hot it felt. Then she began to stroke him.

“Ouch! Not so rough!“, Liam cried out.

“Oops, sorry!” she quickly apologized. Her brother didn't even notice that she had spoken in her normal voice. He just sat there, transfixed, and watched what she was doing. She adjusted her grip. “Better?”

Liam was beyond rational thought. "Oh, yes!" he moaned. ”Now slowly move your hand up and down. Good, just like that. Yeah-haa.”

He was guiding her through her first handjob, which was also the first he'd received from another person. The further he got, the faster and shallower his breathing became. Soon he was unable to speak. But that wasn't necessary, Lisa had understood the basic principles. Eager and paying close attention to his reactions, she thoroughly jerked him off to his climax.

This time she was prepared for what was to come. Amused and a little proud of herself for having done it, she watched as her brother jizzed.

“I hope you enjoyed it, too,” she giggled. "See you in the morning." She then hopped off the bed and headed towards the door. Her hand was smeared all over with Liam's pre-cum and cum. She needed to wash it off now and dashed to the bathroom.
