the woman next door just watches

Jake felt himself getting a little nervous. A complete stranger was watching -- and Jake felt almost paralyzed in the moment. Paralyzed but still slowly fucking Abbie, of course. He became a bit awkwardly aware of his naked body, and suddenly worried that this had gone a step too far.

Abbie sensed his concern. She looked straight into his eyes and said, "We're fine, Jake. Look at me, just keep fucking me, and we're fine."

Jake sighed. She was right. Just keep fucking, and we're fine. He took a breath, pulled back, and with a little turn of his head as if to acknowledge the stranger behind him, he slammed back into her pussy harder than before. His cock throbbed as his arousal increased. He looked at Abbie, and then looked up at the woman from next door.

His gaze was steady, even as he was pumping his cock into Abbie's pussy. Every so often, he would close his eyes or glance back at Abbie (who was grabbing and clutching at Jake's back and ass, either just in a reflexive response to the sex, or to demonstrate to the neighbor that Jake was hers, who could tell).

The woman had walked a few steps from her door toward their shared railing. But seeing that Abbie was pressed up against it, the woman kept a small amount of distance. She was barefoot, and took small, slow steps.

She smiled. Her focus was on Jake. He wondered what her story was. Was she here alone? Was her husband in the room inside? Did she find Jake attractive? Or -- and Jake only thought of this briefly -- did she find Abbie attractive?

The way she looked at him convinced him that he was the focus of her view. He wanted her to see more of him. He pulled out of Abbie for a moment, stepped back, and stroked his cock before returning. He ran his left hand along Abbie's body, starting from the neck, down to the pussy. Abbie altered her position slightly, and Jake re-entered her pussy once more.

Jake had adjusted slightly to his right, which meant he was a little more visible to the woman next door. She stood very still, her bathrobe still mostly closed, but there was a small part at the top. Jake couldn't tell if she had anything on underneath it. She just smiled, occasionally altering her weight from foot to foot.

Jake glanced down at Abbie and touched her breast. She smiled at the contact, and Jake smiled back. He looked back to the woman, who was also smiling -- and had now placed a hand on her own breast, inside her robe. As Jake stroked his fingers on Abbie's skin and paused at her nipple to give a little more attention, it appeared that the woman next door was mirroring his moves on her own body. She touched her own body, brought her hand back to the center of her chest, traced a line downward over her robe, and then let her hand drop to her side.

Jake swallowed. He had hoped she might do something more, but perhaps for now, this was as much as she was going to contribute. She smiled again at Jake, as he refocused his attention on Abbie once more. When he looked back in her direction, the woman next door had turned her back, and was heading back to her balcony door. Jake watched her step back into her room, and close the door behind her.
