Seeing that he still didn't react, they delicately put their hands on his pajama pants and began to pull them down, along with his underwear. Now that they were so close and breathing excitedly, Benjamin managed to find out it was yet again Chloe who had come to see him. There was no doubt that, in her mind, she was avenging herself for what happened in the evening. Even though he had teased her quite a bit, she was still obviously the one in the wrong for peeking at him when he was taking a shower, but she probably didn't take such a small detail into account.
His room was never completely dark because his window was covered by a curtain instead of shutters, allowing for a minimal amount of street light to enter. That let his sister have a relatively nice view of his now-revealed goods. She admired his penis for a certain amount of time, probably also judging if he was waking up, until he eventually sensed her breathing coming closer and closer. He then heard her sniffing his dick and could feel her breathing on his crotch.
She did this for some time but soon switched to the next step. She held her breath and he felt a finger lightly poking his cock. There was another break for a few seconds before she did it again. When he didn't react to all of this, she seemed to judge he was deep in sleep and grew a bit bolder. She began to caress his member with her hands, clearly enjoying the feeling and taking her time to touch everywhere, including his balls. Now that he thought about it, even though she saw it before, she never had the opportunity to touch him. It was obvious she would be curious about it considering this would be her first contact with a male's sexual organ.
He was also wondering how far she would go and kept quiet, silently waiting to sense what she would do. One thing for sure was that she was getting more and more enthusiastic, her breathing accelerating and her hands touching him everywhere with less and less restraint. Under the stimulation, he also had no choice but to get aroused, his dick progressively getting harder. She seemed to notice the change and gasped, stopping everything she was doing to monitor his expression.
He kept completely still and she finally judged she was still in the clear, resuming her molestation of his now-hardened member. She put her small hands on his rod and slowly moved them up and down his length, appreciating the changed texture. Soon after, he felt a wet sensation on his penis and shivered a little. He guessed she had used her tongue to lick him. When he still didn't wake up with all of this, she continued to lick him, going from the root of his cock to his glans and even aiming at his balls a few times.
After a few minutes of this, he heard the sound of clothes. One of her hands left his member and he soon could hear her playing with herself while relishing in the situation. Soon after, she put her mouth on his glans and kissed it several times noisily before suddenly gobbling his whole member. She let out a small moan of pleasure and moved her head up and down, effectively giving him a blowjob.
She noticeably had no idea of what she was doing because her fellatio was a mess. She sometimes let her teeth touch his penis, sending bursts of pain to his brain. She only used her tongue to taste him and not to pleasure him. She even tried to do weird things that were far beyond what she could handle, like suddenly deepthroating him, making her gag and cough hard. Another example was her trying to aspirate on his dick hard as his mother had done. That also failed grandly and she got out of breath immediately, having no choice but to release his member for a moment. Finally, she gave it her all to bob her head fast on him and give him an intense blowjob, only to get tired soon after and stop yet again, using her hands on him while she recuperated.
Of course, the whole process was extremely noisy and she had lost any of her initial prudence. She was probably so excited that she didn't care anymore, focusing her full attention on his penis. He let her play with him for a long time until her messy efforts were finally enough for him to get close to his release. Just before his orgasm, he began to moan on purpose, trying to signal her that he was close. She froze for a few seconds but then fellated him again with all she had while still working on her pussy at the same time. Finally, he let out a groan of pleasure and came into her small mouth, filling her cavity with wave after wave of sperm. She climaxed at the exact time she felt his semen in her mouth, moaning blissfully for a moment before soon gulping his seed as quickly as possible.
Once they were done cumming, Benjamin finally decided to open his eyes. The situation in front of him was exactly as he expected, with his nude little sister stuck to his dick in post-orgasm ecstasy.
"What do you think you're doing, Chloe?"
She jumped so badly that she let go of his cock and looked at him in panic. She opened and closed her mouth for a few seconds before claiming, biting her lips.
"It-it-it's all your fault, Ben! It's because you kept teasing me!"
Then, without waiting for him to answer or react, she stood up over his dick and instantly dropped her waist down on it, piercing her hymen in one go and strongly penetrating her virgin pussy all the way to her depth.
"Owww!"
She trembled in pain at her brutal deflowering, tears appearing in her eyes. Benjamin reacted in dismay and called out.
"What are you doing, stupid girl!? I can't believe you did that!"
She looked at him with tears falling down her cheeks, trying hard to smile through the pain.
"Hehehe, serves you right! I'm the one who took your virginity!"
