A Deal and White Stains

After Marco left, the house fell silent. Lucy collapsed onto the living room sofa, her body still vibrating with the adrenaline and excitement of the last few hours. Her mind was a whirlwind, replaying every kiss, every caress, every word spoken. She was thinking about Marco's expression, about the hardness of his erection, when her thoughts were interrupted by a knock on the door.

She frowned. Had Marco forgotten something? She got up and opened it, only to find herself face to face with her neighbor.

"Hello," he said, with a strange calmness. "Sorry to bother you. I just noticed something curious. The first boy who left your house was with you for a long time. And, when he left, he had an erection very similar to your boyfriend's, who just left."

Lucy tried to act tough, but his words had taken her by surprise, leaving her nervous and, to her own shame, a little turned on. "And what business is that of yours?" she snapped.

The neighbor smiled, but not in his usual lewd way. It was a kind, almost fatherly smile, as if he were a completely different person. "I'm not saying it to bother you," he said softly. "I just imagined that maybe they did naughty things with you. And that reminded me of our... deal. You mentioned that to get a girl's panties, a man had to earn them. And I was hoping that, if I asked you nicely, maybe you would give them to me."

The request threw her off. His unexpected kindness, the fact that he remembered and respected the rules she herself had imposed, made her feel strangely ****. She felt a little bad for having been so rude to him. And deep down, a new wetness began to form between her legs. After all, a pair of panties wasn't such a bad thing.

"Alright," she said, her voice softer than she intended. "I'll give you your panties. Wait a moment."

She closed the door, leaving him outside. She ran up to her room, took off her shorts, and slipped the panties down her legs. They were very damp, much more so than they had ever been, soaked with the fresh wetness of her love juices, a product of Marco's caresses and the arousal with Javier. She put her shorts back on and went downstairs, with the small piece of fabric in her hand. Upon opening the door, she noticed the neighbor's calmness had vanished; he now had a visible erection under his pants.

She handed him the panties. The instant his fingers touched them, his face transformed back into the mask of the pervert she knew.

"Mmm, they're damp and warm," he said, bringing them close to his nose. "And your love juices are fresh. I'm going to have a lot of fun with this," he added, as he grabbed his own erection over the fabric. Before turning to leave, he looked at her. "But a deal is a deal. Since I have a new toy, I'll give you something in return."

He reached into his pocket and pulled out the first item she had given him days ago, the panties she had taken off on the street. He handed them to her and left without another word.

Lucy closed the door, confused. She looked at the panties in her hand. They were dry, but they had several whitish, stiff stains stuck to the fabric.

A shiver ran through her. Could it be semen?
