Wait to see what happens...

You give a sidelong glance to Lacey, who remains crouched next to you, staring intensely at the two girls in the clearing. At first you thought she might not have been cool with spying on your friends, but judging by the flushed expression on her face she is enjoying this every bit as much as you are. She bites her lower lip in absorption and you turn back to the scene at hand to see what had caught her attention.

In the clearing, the girls had crawled out of the water and onto the nearby bank, bringing them closer to your hiding spot. Claire lay on her back while Amanda sat atop her, straddling the smaller woman at the hips. Claire's hands had roamed down her partner's back and rest lightly on her protruding ass as they locked lips in a tight embrace while the sun shined through the trees onto their glistening skin. As they lay there writhing together, however, Claire's grip on Manda's ass tightened, pulling her cheeks apart slightly from the contraction and giving the careful onlooker (the two of you) a great view of her naked pussy, which rubbed eagerly against Claire's, whose questing fingers inched closer to her friend's slit. Amanda's hips bucked even harder as the other girl ran her fingers down the length of her exposed crotch, teasing the opening as slightly as possible, earning a lustful bite on the bottom lip from the girl on top of her.

A slight shuffling to your left causes you to tear your gaze away from the two nymphs by the water. Normally you would be loathe to ignore two of the hottest girls you knew enjoying each others' bodies, but you were still in a forest and where there's woods and water there are most likely bears. Instead you find yourself staring at Lacey, who has sank even lower to the ground and is no longer propping herself up her elbows. Instead, one arm is extended outward to hold aside a branch blocking her view, while the other one is pinned underneath her torso and hips, her hand working away at her own crotch. Her jeans rest halfway down her hips, exposing just the top of her as and askew panties to you. Without missing a beat, you shimmy closer to her and slide your hand down the back of her underwear, feeling her tight ass against your palm as you reach around the back for her pussy. Lacey's shoulder tense in surprise, but only for a moment before her hand meets yours within the confines of her jeans, and she pulls your fingers into her waiting pussy. You pump your fingers in and out, feeling her wetness as you cup her crotch from behind.

Lacey lets out a little squeak of satisfaction as you enter her not for the first time that day. But she doesn't even turn to look at you, instead keeping her gaze locked on your two friends in the clearing.
