Then he started to fuck her wildly as if he were a bull provoked by the matador's flag.
"It's too fast! I can't take it! Lucas, stop!" Rachel screamed.
Lucas stopped as she requested and looked at her, confused. "Why, Rachel?"
She reached out, her hand trembling, and pointed at Lucas. "Be gentle at the beginning of sex. You were using too much force."
"I'm so sorry, Rachel. Did I hurt you?" Lucas asked nervously. He pulled his penis out, bent down, and checked on her.
"No. Do it again. But this time, slow down," she said gently.
He nodded and put his penis in her vagina again. Only this time, he was nothing but gentle.
Rachel groaned in satisfaction.
"OK. Time to speed up." Rachel felt like she was a patient teacher, telling Lucas when to speed up and when to slow down.
And Lucas was no doubt a very obedient student.
While enjoying the pleasure, she thought, 'Lucas is learning so fast. He can now master the pace of sex. Is it all biological?'
Suddenly, Evelyn shouted out of Rachel's bedroom.
"Rachel, I'm back with the steak. Are you home?" Evelyn knocked on Rachel's door, startling both Rachel and Lucas.
They stopped at once and froze on the spot, unable to move at all.
"Rachel, are you in there? I'm coming in," Evelyn knocked again.
Hearing the doorknob turning, Rachel frantically shouted, "Mom, don't come in! I'm masturbating!"
Evelyn, about to open the door, was stunned. She blushed and withdrew her hand.
"I got the food back. Get downstairs and help me with it when you're done," she said and ran downstairs, still blushing.
In the room, Rachel felt her head dizzy. She was so ashamed that she didn't have the courage to walk out of her room.
She thought, 'Gosh! What did I say? I'm doomed. This is probably the most embarrassing thing I've ever done in my life.'
"Lucas, come on. Wrap it up and leave," she patted Lucas, urging him.
Lucas nodded and suddenly kissed her.
Her eyes widened, and she pushed his head away with great force.
"What did I say? You should only kiss the girl you like," she said sternly. "You are my favorite, Rachel," he said, looking at her seriously.
His words made her stun for a second, while he kissed her again. Their lips touched, their tongues entwined, and they kissed with great passion.
Suddenly, she had doubts about herself, thinking, 'I'm kissing Lucas? We kiss while having sex? Is that really okay?'
In the next second, Lucas's body stiffened, and Rachel felt the pulsing of his penis within her as her vagina was filled with burning liquid.
Panting, he pulled his penis out of her vagina, making a sound like popping champagne.
"Lucas, go back to your room. Make sure Mom doesn't see you," Rachel urged, wiping his semen leaking from her vagina with a tissue.
Lucas nodded, opened the door, and peeked outside carefully. Making sure there was no one around, he tiptoed back to his room.
In the kitchen, Evelyn was washing the groceries while pondering.
'Rachel is an adult already, and she has her own ideas. Though I'm her mom, I shouldn't throw my weight around about her masturbation.
Speaking of that, I'm more worried about Lucas. It's been a while since the last time he came to me. Is he used to masturbating alone?' "Hey, Mom. How can I help?" Rachel suddenly asked behind Evelyn, interrupting her thoughts.
Startled, Evelyn turned around and saw that Rachel's face was still tinged with an orgasmic flush.
"Rachel, peel the onions for me. OK?" She pointed at the onions on the table.
Rachel nodded and sat down to commence the task.
As Lucas walked down the stairs, he waved at them, and then he ran out. "Mrs. Primo, Rachel, I'm off to see James. Bye!"
Watching his back, Evelyn asked, confused, "He's here all this time? I thought he was out already."
"He was probably sleeping," Rachel smiled awkwardly and then watched Lucas through the window as he mounted his bicycle. Gradually, some thoughts occupied her mind.
The things Lucas said when they were kissing emerged in her mind.
He said, "You are my favorite, Rachel."
Peeling the onions, Rachel felt a pang of regret. Lucas had been with them since he was little, and though they weren't related by blood, after years, he was like her baby brother already.
She thought, 'Am I doing the right thing? I lured him to have sex with me, claiming that I was teaching him knowledge about sex. Lucas is family!'
As she looked up at Lucas's back again, a firm thought came to her mind.
'It cannot happen again. I have to stop Lucas from having sex with me.
