Ohohoh I know once piper catches them she's like "that's what I was feeling" and "don't stop because I'm here, in fact continue"
All three don't talk about it but Piper becomes their psydo-therapist, she watches them fuck and maybe sometimes cuddles one or both afterwards
i see you and raise you the hc of Aphrodite demigods having like a heat when they go into puberty, they can sense the sexual tension around them and suffer because of it. camp offers a suppressant to combat this, and piper takes a ton on the quest—however, she didn’t anticipate this sudden spike in tension as soon as nico got on board, and she is soon to run out if she ups her dosage.
she knows it’s them and sets things up to walk in on them on purpose (because it is that bad). when she arrives, she finds nico fucking leo from behind, pinning his hands behind his back with one hand. his other hand rubs and squeezes leo’s ass. leo’s back is arched, panting and rolling his hips back desperately against nico. his face is flushed, wet lips parted, eyes half lidded and dark with lust.
it’s a beautiful sight to say the least.
piper’s tension increases tenfold. her face is flushed, her nerves so scrambled she might be sick.
leo freezes when he sees her, biting back a moan as he tells her in or out, but shut the door.
nico raises a brow, challenging her without speaking. piper shuts the door and locks it, walking over to them with pleading eyes.
“couldn’t take the tension anymore,” she says. “i don’t get it…” you guys were foster brothers for years. “but i want…i wanna watch. it might help me find relief…”
nico is still rolling his hips in little movements, leo whimpering with every thrust. “i can do you one better,” he pulls leo back by his hair. “think you could help her out, baby? use that pretty mouth of yours?”
leo whines and nods, a shiver coursing through him as precum leaks from his cock.
it makes piper wet like nothing else.
she gets on the bed, stripping herself of her shorts and underwear. leo gazes a bit too long at the clothing item before the perv asks if he can keep them. piper’s admittedly a bit surprised when she says yes.
piper shyly spreads her legs, and leo goes all in with no hesitation. he’s off base at first, though the effort is cute. piper tangles her fingers in his curls, guiding him until he licks right along her clit, and she shivers. leo licks and sucks the bundle of nerves, causing piper’s face to flush as she throws her head back, gently knocking against the headboard. he wasn’t experienced at all (and neither was piper), though he made up for it in how eager he was.
nico can’t help but watch piper as she was being pleasured—her dark eyes, the soft pants escaping plump, spit-slicked lips. it’s late in the night, and she’s wearing pajamas—nico sees her nipples harden through her thin shirt.
he didn’t have to be straight to acknowledge that she looks really good.
“he’s makin’ you feel so good, huh?” nico muses, leaning in close, breath warm on piper’s lips. “he’s makin’ me feel amazing, too…”
piper nods with a soft whimper, fingers grasping leo’s hair, unable to help but whisper: “he’s your brother…”
“mm-hm,” nico hums—and it’s sickening, but he’s unable to help but grin. “he didn’t get my good looks, i’m afraid…”
and then nico kisses her, long and deep. it muffles the moan that escapes her as she comes, hips twitching, pushing desperately against leo’s lips and tongue. she pants against nico’s lips, and for a moment, nico imagines what it would be like to be inside her. he only really wants leo, though he wouldn’t say no to changing things up once or twice. it’s strange, though the thought causes his cock to twitch, and he comes deep inside leo. not long after, leo comes last, muffled between piper’s pillowy thighs.
leo lets out a sigh as nico pulls out, laying his head on piper’s lap. piper is silent, the shock washing over her. she doesn’t regret anything—and she appreciates nico getting up to clean. she does know, her fingers still brushing through leo’s curls, that she got into much more than she bargained for.
