A Surprise for Marco and Gabriela

Her sister's shout was like a bucket of ice water. Lucy became instantly nervous, her mind snapping abruptly out of the haze of arousal. Had she heard them? How long had she been there? Javier stopped touching her breasts, but in her panic, she didn't even adjust her blouse. After a few seconds of silence, her sister spoke again, her voice more insistent, and that was enough to pull her completely out of her erotic trance.

"Wait a couple of minutes!" she shouted back. "And let him in!"

Quickly, she pulled down her blouse, her breathing still ragged and with sweat beading on her forehead. The air around her was impregnated with her scent, a mix of perfume and arousal that Javier inhaled deeply. He felt like he was on top of the world. Not even in his best and wildest dreams had he imagined touching Lucy that way. He didn't understand why she had gone so far, but in his mind, there was only one explanation: she felt a strong attraction to him.

Taking advantage of her moment of confusion, Javier took one of Lucy's hands. She gave him a strange look as he proceeded to place her hand directly on his hard erection. "My cock and I are very grateful for this," he whispered, his voice hoarse with desire. "You have amazing tits. And don't worry, it'll be our secret."

Javier truly believed he was stealing his friend's girlfriend. Lucy, the most beautiful girl in school. He knew they would all be going off to college soon; they were already eighteen. It was possible that in college, another guy would end up taking her anyway. What Javier didn't know was that he wasn't a conqueror, but a piece in a much more complex game.

Lucy quickly pulled her hand away from his erection. It felt hard and hot under her palm, and she could almost swear it was the same size as Marco's. She also noticed the wet tip through the fabric. She took a deep breath, trying to calm herself. "Thanks," was all she could say. "And please, act normal so Marco doesn't suspect anything."

For Marco, arriving at Lucy's house was strange from the beginning. It was Gabriela, Lucy's sister, who opened the door. Marco immediately noticed that she was incredibly nervous. Instead of inviting him in as usual, she asked him to wait outside while she let Lucy know he was there. Several minutes passed before Gabriela opened the door again and invited him in, only to make him wait a little longer in the living room.

Finally, she told him he could go up. Upon entering Lucy's room, he noticed that she too was nervous and a bit disheveled. Javier, in contrast, greeted him with overflowing joy and a smile that didn't reach his eyes. Marco was about to close the bedroom door when he noticed something else: Gabriela, from the hallway, was staring intently at her sister with an indecipherable expression.

Before Marco arrived, Gabriela had been in her room listening to music. She got bored and turned it off, and it was in that silence that she heard strange noises coming from the room next door. She left her room and crept up to Lucy's door. She could hear clear, rhythmic moans.

"Mmmm... mmm..."

Then, a man's deep voice, followed by more moans.

"Mmmm..."

A smile formed on her face. Apparently, Marco had finally dared to go further with Lucy. Her sister had told her several times how frustrated she was that Marco never went beyond caresses and kisses. She felt a little envious hearing it; it seemed like Lucy was enjoying it a lot.

She was about to go back to her room, to give them privacy, when the doorbell rang. She went to see who it was without much caution. Her mother would be late coming home and, in any case, she would open the door with her own key.

Upon opening the door, Gabriela froze. On the threshold stood Marco, smiling at her. Panic invaded her. If Marco was here, who was the man in the room making her sister moan?
