He could not be certain that she knew he could see her, but he had a feeling she knew.
His window was just opposite and above hers, yet she never closed her curtains. She kept her bedside lamp on, illuminating herself on her bed.
Every night at 9, she would take a shower, leaving her ensuite door open so he could see her through the bedroom window. Then she would step into the bedroom wrapped in a white towel.
She would moisturise her legs and arms, before dropping the towel to moisturise the rest of her body. She had a beautiful round butt and round perky breasts. He could even see her mound was neatly trimmed.
Then she would lay down on her bed, propped up against her pillows, and start touching herself. She would play with her breasts, squeeze her butt.
Then she would cup her mound, start circling her clit with a finger. He would watch, mesmerised, as she raised her hips and started fingering herself. He would press himself up against his window, as though to try to get closer to her.
He left a dim light on in his own room and wondered if she could see him, sometimes he could swear she was looking up into his window as she humped her hand. He liked this bit the best, where she would flip over onto her stomach and start riding her hand underneath her.
