Comes fury then laughter

Stacy woke up from her daze, who knows HOW much later. She sat bolt upright, her hair sticking out at odd angles and tangled with the odd stick. She couldn't open her left eye until she had scooped off a great blob of sticky goop, which she shook away in disgust. The boys were both sat in the same places... just watching her. Looks of great apprehension were plastered on their faces, as there bloody well should be.

“You CAME ON ME?!” She yelled, mostly at Mark, throwing the nearest thing she had to hand at him. It happened to be her own underwear again, but she didn't care. The girl proceeded to throw the rest of her clothing at the hapless boy while he cowered from her fury. “That's absolutely disgusting! You pig! You sick-fucking-pig of a boy! Why would you do that?!”

Mark tried his best to dodge and weave the barrage of female clothing, and then cushions and small rocks, that came his way, but could not for the life of him find any words of defense.

“I’m sorry! I just… You were… I couldn't! Ow! Stacy! I didn't mean to… I’m sorry!”

The boy looked genuinely shocked by his own actions… Even as she maintained her own fury Stacy couldn't help but be aware she’d actually forgive him. The moment had been so intense for her as well after all… It just felt so grimy to be sitting there, sensing their leavings drip slowly down her chest with every angry movement.

Peter entered himself into the equation, against all sense of self-preservation. “I’m sorry too Stace… I thought, for a second... you wanted me to… That was stupid… it was just so amazing, watching you…”

The wrathful girl turned to him with fire in her eyes… and deflated immediately. The boy looked utterly dejected, as if certain she would never speak to him again. That this was the end of the bond they had all shared so long. Stacy looked at him and couldn't help but still feel the echo of that inviting smile she herself had worn, however delirious she'd been at the time.

“Oh, Pete… it's okay… I sorta did want… just in that moment…” She swept her gaze across them both once more, causing Mark to instinctively flinch. The girl sighed, and flopped back onto her haunches, scraping up another little splatter of semen off of her own breast and squidging it experimentally between two fingers.

“Look… I get it… you both just got carried away. That was pretty amazing after all… Just… don’t do it again okay?! Bring some tissues or something…”

The boy's glanced at each other in unlooked for wonder. “Again…?” Mark asked, tentatively. “You mean…?”

This time Stacy was the one looking surprised, had they not just experienced what she had? “Of course! That was incredible! Unless… you don’t want to, or...?”

There was an immediate rush of incoherent assent from the pair of them, so Stacy continued… picking her way carefully through her own thoughts on the matter. While also acutely aware she was still absentmindedly playing with the cum they had coated her in.

“Look… This last week has been… fun! It's been the closest I’ve ever felt to anyone. I mean… I love you guys! You both found me when I was at the lowest of the low, and have looked after me ever since. I don’t mind us… playing around a bit AT ALL… it's just… fun, y’know… natural, like we keep saying…”

She looked up. The boys were hanging on her every word again, like serpents from a basket. They almost seemed to be creeping towards her. The thought sent a shiver down her spine as she continued.

“But it has to be just between us, agreed? No boasting behind my back to the boys in the locker room?! Whatever we do… is our own private business, yeah?”

There wasn't a second thought to their united agreement, spurred on by the luringly open words ‘Whatever we do’ if nothing else. As always, Mark was the first to speak.

“So does that mean… we could also try, like, kissing and stuff?”

Stacy laughed at the romantic innocence of him.

“Well... yeah. But wouldn't you prefer if I rinsed Peter's cum off my face first?!”

He blanched at that and they fell about laughing again, each secretly taking stock of what new opportunities this agreement might mean.
