Lil is in a lounge chair on the patio getting head

Gary couldn't find Lil in the living room. She'd been on the fringes of tonight's sex party, watching wide-eyed at all the everysexual and group combinations on display from Stuart and his freaky surf crowd, from Stu himself who enjoyed having younger men and women around to watch, toy with, fuck and occasionally matchmake, like Trent and Debbie, to oddballs like Reiko, who was a graceful, muscular little lesbian surfer who went for any and all women -- except never with Sharon "trashy drunk drama bitch" and crossed over to hetero sex for redheaded stringbean Kevin and only Kevin. "I'm a one dick chick." Kevin had given up his ass for Stuart once, but other than accepting cocksucking from just about anyone, Kevin pretty much stayed glued to Rei. After Rei had pried him loose from Sharon, who had grabbed Gary and made a little too much of flaunting him as a **** fuck in front of Kevin and Rei. It hadn't all been Stu's surf crowd regulars tonight, Bernie and Lil certainly weren't, and Lil had asked about bringing a couple of people she knew. But it was mostly the regulars getting naked. And now they were getting gone.

Gary shrugged. Maybe Lil was in the bathroom or had slipped back to her bedroom upstairs?

The sliding glass door to the patio was open. Gary went over to close it for the night when he heard Lil's voice outside.

Lil was lying in a lounge chair on the patio, moaning with pleasure as she guided her partner's head between her spread legs using both hands.

It was too dark for Gary to see who was eating out his sister, but from her sounds, whoever it was was doing a good job. Lil was loving it.

Gary's cock throbbed erect as he watched and listened. Lil was okay, probably, but it was hard to really know if he didn't know who Lil was getting off with.
