And a moment later, Hailey's follow. Her build is a bit closer to Sin's own, and definitely on the petite side. She pins Hyacinth's arms to the bed on either side, leans down, and kisses her fiercely.

Hyacinth blushes and kisses back, her breath hastening a little.

She breaks the kiss, nipping Sin's lip teasingly as she pulls away, and spreads her wings, carefully pressing each hand down with a wingtip.

She smirks down at Sin and caresses her cheek. "And now my hands are free, while you're still helpless." Her other hand slides down the foxgirl's neck, then further, caressing the gentle curve of her breast.

Hyacinth trembles at the trailing touches, her face going very red. She can't even hide it with both her hands pinned. 

No, she can't hide it at all, and that's just how Hailey likes it.

Her fingertips find Sin's nipples, teasing little strokes around the areolas, flicking softly across the sensitive nubs.

Hyacinth exhales hard, and her thighs and arms tense and relax.

"... oh wow," she breathes.

Hailey's grin widens at how affected Sin is, and then she pinches Sin's nipples.

Hyacinth tenses and exhales. "That's... a lot..." She sighs and clenches her toes. "It's different when I can't even escape it..."

"Yeah, that definitely intensifies things," she agrees. Her tail wraps around her waist, then slips down between her legs to brush briefly against her own cunt before continuing to tease the tip of the spade along Sin's folds. Her fingers go back to lightly circling around Sin's nipples. "Such a pretty little fox, and so vulnerable."

Hyacinth lets out a soft gasp as Hailey's tail nestles into the cleft between her legs, and her hips roll instinctually against its spade tip as she bites her lip. 

"Hailey..."

"Sweet, little Hyacinth," Hailey purrs. She pinches Sin's nipples again, just as her tail presses a little firmer against her sex.

Hyacinth eeps again. 

"... Look... looks like.. you've got me..."

She turns her head to the side but can't conceal her bitten lip. 

"I do." Her voice is a smug purr. She lifts up her left hand, and then with a little flourish, a knife appears from her inventory, held delicately between her fingertips. She twirls it slowly in her fingers, letting Sin get a good look. Her tail teases higher along Sin's folds, the tip swirling around her clit in little circles.

Hyacinth's gaze doesn't part from the knife, but if anything she looks more aroused. 

"... I am so, so doomed."

Hailey grins wickedly down at her. She presses the flat of the blade against Sin's right breast, the tip resting just atop her nipple, and pinches Sin's left nipple and flicks her tail tip across Sin's clit at the same time. She leans slowly down and murmurs, "You really are."

The cold metal draws a hiss from Hyacinth's lips —

— but then the flick of Hailey's tailtip over her clit replaces it with a soft moan.

Hailey licks her lips at the hiss and the moan, then leans down and captures Sin's lips with her own, kissing her deeply. The length of her tail caresses against her own folds while the tip keeps flicking lightly across Sin's clit — and the whole time she presses the flat of the knife down harder, so there's no way Sin can forget it's there.

Hyacinth kisses back deeply and eagerly, her body flushing with sweat as Hailey touches and teases her.

"Hailey..."

She grins into the kiss, then nips Sin's lip again as she pulls back up. The tip of her knife teases little circles around Sin's right areola, and the tip of her tail matches those circles around Sin's clit exactly, all while her other hand gropes and squeezes Sin's left breast.

Hyacinth goes very quiet, her whole body tensing. Her hands push against Hailey's wings for a moment, then fall back. 

"And this isn't even the right spot. This is just me enjoying teasing you here 'cause I'm a fuckin' leftie." She switches hands, slowly dragging the tip of the knife into the valley of Sin's breasts and then back up the swell of the left, circling the nipple again. The spade of her tail rolls up and thrusts into Hyacinth's cunt, the length teasing lightly against her clit.

"You're not allowed to cum until you beg me for it, by the way."

Hyacinth lets out a small flustered sound —

Then as Hailey slowly sinks her tail into her, she trails off into unsteady laughter that turns to a long, heavy moan.
