Okay, here is the revised version of your text with the names changed:
Charlotte waved her hand impatiently. "Gotcha, Mom! Go to sleep!"
Evelyn was about to go back to her room, but she suddenly stopped when she passed the stairs, thinking, 'How's Lucas doing? He's OK by himself, right?'
She glanced in the direction of the stairs, sighed again silently, and returned to her room.
Yet what she didn't know was that Lucas wasn't by himself. Instead, he was in Rachel's room.
"What do you want?" Rachel asked while looking at him. She was doing yoga, the tight yoga pants showing her sexy body off perfectly.
Lowering his head, Lucas said, a bit shy, "Rachel, can we have sex again someday?"
"What?" She stopped doing yoga and looked at him, shocked.
Worried that she might get upset, he quickly explained. "You said we had sex yesterday, but I didn't have a clue what had happened. Well, you're supposed to be pregnant after sex, right?"
Rachel cocked her head, looking more and more puzzled. "Lucas, what's your point?"
Actually, Lucas himself didn't know the answer. He just wanted to be honest with her about his thoughts.
"In fact, I didn't have a chance to enjoy our sex. Feels like a waste."
Rachel interrupted him before he could finish and leaned closer to him with a smile, her plump breasts pressed against his arm. "So, you wanna have sex again, right?"
Blushing, Lucas nodded. He was still a bit worried. "Rachel, am I bad? I heard that one's not supposed to have sex unless one wants a baby."
Rachel burst out laughing. "Who told you that? It's ridiculous!"
As she laughed, he felt her breasts swaying rhythmically.
After a while, she stopped laughing and turned serious. "Listen to me. Sex is essentially an intimate act between a man and a woman..."
The lecture on sex lasted 15 minutes, and Lucas finally realized that he had been wrong this whole time.
He lowered his head, unable to believe how stupid he was. "Even man and woman can have sex... I had no idea, I'm such a fool!"
Rachel felt sorry for him.
"There, there. Don't cry. You want sex, right? We had sex yesterday. Might as well do it again. Better to put knowledge into practice, right?" she said and took off her yoga pants slowly under Lucas's surprised gaze.
On the bed, Rachel took her clothes off one by one and ended up lying naked in front of Lucas.
"Rachel, are you serious? You really wanna have sex with me?" Lucas stared at her naked body and swallowed subconsciously.
Rachel moved from the bed to Lucas, her plump breasts pressed against his face. "For me, doing it once or twice is just the same," she smiled. "I'll make you remember today what sex is!"
Looking at her breasts, Lucas gasped. Then he nodded and reached out for them.
"Wait." To his surprise, she patted his hand away.
Under his puzzled gaze, she looked at him suspiciously. "Are you trying to trick me into having sex with you by pretending that you know nothing?"
He shook his head, looking nothing but serious. "I'm being completely honest, Rachel."
She stared at his expression without blinking, making him feel very uneasy.
A minute later, she suddenly grinned, saying, "I believe you."
Then she curled her finger at Lucas while lying on the bed. "What happened yesterday caught me off guard. Today I'll let you know how I'm gonna discipline you. Go, take off your clothes!"
Lucas nodded and did as he was told obediently. Though Rachel was prepared, she still froze when she saw Lucas's big penis.
She exclaimed inwardly, 'Damn! That's the biggest penis I've ever seen!'
"Rachel, here it goes," he said and then bit her breast. Then he started to squeeze both of her breasts and licked her nipples.
Under his attack, she groaned while thinking, "Where did he learn to do that? Are all men born knowing how to do this?"
She uneasily twisted her legs, feeling that her vagina was about to be completely wet by her own fluids.
"What should I do now, Rachel?" Lucas asked, looking at her.
"Put your penis in my vagina," she spread her legs, revealing her genitals.
Beneath her dense pubic hair was her labia, where the wet fluid oozed through the crevice, leaving Lucas stunned.
"What are you doing? Come on! Put it in!" she urged.
He nodded quickly. Then he held his penis while looking at her closed labia and asked somewhat awkwardly, "Rachel, where's your vagina?"
Helpless, Rachel sat up, pushed him down, and got on top of him.
"I shouldn't have had sex with a virgin. You couldn't even find the spot!" she sighed, grabbed his penis, and pointed it at her vagina. "Remember the feeling. Once you find the opening, thrust it in," she said, put her vagina up against Lucas's penis, and sat down.
Feeling his penis inside her more and more, she couldn't help but groan. Meanwhile, as yesterday, Lucas felt great again.
Enjoying himself, he savored the feeling while thinking, 'That's it. Feels like my penis is in a warm, wet hole. Damn! That feels awesome.'
At the same time, Rachel was on top of him, swaying her body. As a result, his penis was inside and out of her vagina rhythmically.
"Rachel, your vagina is so wet," he groaned.
She looked down at him and explained while panting, "When a woman's vagina becomes wet, it means she's ready for sex."
"Gotcha, Rachel. Sex is awesome!" he groaned and suddenly grabbed her butt, getting on top of her.
"Easy! You're doing it too fast!" she screamed.
Lucas put her feet on her shoulders while fucking her non-stop. He was so fast that it was a bit too much for her.
