A blonde vixen, clad in a tight dress, boards the metro, her eyes locked onto a prey. She slides into the seat beside him, her leg brushing against his. He stiffens, not from the train's motion, but her touch. She leans in, her breath hot on his ear, "I've been a bad girl. I need a man to punish me." He obliged, his hand forcefully hiking up her skirt, fingers sinking into her wet folds. She moans, her juices coating his hand as he finger-fucks her, her body writhing, her pussy clenching around his digits. He pulls out, his hand glistening, and she sucks it clean, her eyes never leaving his, ready for more.
