Nicole has the best vantage point

"What?" Wynonna eventually said.

She was just staring. It wasn't every day you came home to find your sister stark naked and stuck in a window. Waverly slumped forwards, crossing her arms over her hanging breasts rather than using them for support, blushing.

"I had a couple of accidents," Waverly said. She wasn't sure how to even begin explaining. "And the door was locked. So I tried. And here I am."

"Accidents?" Wynonna said, disbelieving.

Waverly nodded. Wynonna still stared at her. It made Waverly's cheeks warm, though not as much as when she felt Nicole's hand walk up her thigh.

Well there was that too. Not only was she currently stuck naked in a window in front of her sister, but her girlfriend was behind her crouching right next to her ass. She probably couldn't have expected anything different. Unfortunately it reminded her that she wasn't just exposed from the front, Wynonna's presence had distracted her from the fact her butt was out there too.

At least that should mean Nicole had her pants on. Waverly was jealous.

"You ok?" Wynonna said.

"Embarrassed," Waverly said.

"Well, let's see if we can get you out," Wynonna said.

She moved closer the first second Waverly felt a tongue. She squealed, cheeks reddening by several shades.

"Waves?" Wynonna said.

"Give me a sec?" Waverly said pleadingly.

She tried to nudge Nicole with her foot. Being naked in front of her sister was bad enough, she didn't want Wynonna to catch Nicole doing that to her! It felt as amazing as ever, but it really wasn't the time.

Naturally enough though, Nicole was enjoying herself. Waverly could feel her enthusiasm, both for tasting her and for just having the chance to grab her ass, out of sight of Wynonna while Wynonna was further in the room but unforgettable to Waverly.

"You want to stay in there?" Wynonna said.

"Yes!" Waverly arched, then her eyes widened. "No! I mean no! Just, oh god, just got a crick in my back I want to stretch out first."

She didn't sound convincing, but she was too distracted to worry about that just then. Nicole's tongue completed another circle against her, bringing Waverly to the verge of what promised to be simultaneously the most intense and most embarrassing orgasm of her life.
