A/N: this is a little idea i had in my notes, so i hope you guys enjoy! also let me know what you guys would like to see!!
Billie can always tell when Y/N is close—not just from the way her body tightens, but from the way her breath catches in her throat, the way her fingers twitch helplessly, the way the smallest, broken whimper slips out before she can swallow it back.
But tonight Y/N is already trembling before Billie even pushes back in.
They’re lying on their sides, bodies flush, Billie curled around her from behind. One of Billie’s thighs is slotted between Y/N’s, lifting her just enough to angle the strap perfectly. Y/N’s still shaky from her last orgasm—eyes wet, cheeks flushed, breath hiccuping. A strand of hair sticks to her temple.
Billie’s face is soft behind her; flushed, panting, eyes half-lidded but focused entirely on Y/N’s face.
“Baby.” Billie murmurs, voice warm against Y/N’s neck. “You okay?”
Y/N tried to nod, but it’s a desperate little movement.
Billie kisses her shoulder. “Tell me to stop if it’s too much.”
“It’s not—” Y/N tried to say, but her voice breaks as Billie rolls her hips gently forward, the slow glide pulling a fragile whimper straight from her chest. “It’s not too much.”
“Okay.” Billie whispers, honey-soft. Her hand smooths over Y/N’s stomach, pulling her closer. “Okay, sweetheart.”
Billie pulls back, and thrusts in deep.
Y/N cries out—a half-choked, half-relieved moan. Her hand scrambles for Billie’s forearm, gripping tight as her whole body jolts forward from the force.
Billie’s hips grind slowly, hitting that spot inside Y/N that makes her legs tremble uncontrollably. Wet, messy sounds fill the room, each thrust pushing another tear down Y/N’s cheek.
“B-Billie—“ She gasps, voice thin and breaking.
Billie’s breath catches against her ear. She presses in deeper, slowly only so she can guide Y/N’s hips back with her hand, holding her exactly where she wants her.
“I know.” Billie whispers, and the words tremble with how badly she’s trying to stay gentle for her. “I know, baby.”
Y/N shudders, a soft sob curling out of her throat, her body clenching hard around the strap.
“Billie—please—“ She whines, barely audible. “It’s so—“
“I know.” Billie whispers again, her chest pressed to Y/N’s back, her lips soft against the curve of her jaw. “I’m right here.”
Billie sees it. The tear sliding down from Y/N’s chin, hanging there before dropping onto the pillow.
She doesn’t pull out. Not even an inch.
She just pauses her hips long enough to slip her hand under Y/N’s cheek and gently turn her face toward her.
Y/N’s eyes are glassy, lashes wet, lips parted in a tiny, trembling gasp.
“Come here, sweet girl.” Billie breathes, her voice barely there.
She leans in slowly—giving Y/N a moment to breathe.
From the bottom of Y/N’s chin, tracing the path the tear left behind. Her tongue drags upward, tasting salt—and all the while her hips keep moving, nudging inside Y/N with every sweep of her tongue.
Y/N shudders so hard her breath slips like a sob.
Billie’s lips press tenderly to her temple. “I’m so sorry, baby.” She murmurs, voice cracking with sweetness and desire and apology woven into one. “It’s so much, I know.”
Y/N whimpers brokenly, pressing her forehead against Billie’s. “Don’t stop.”
Those two words destroy her.
Billie eases her hips back only to slide in fully again, burying the strap deep inside her, their bodies shaking against each other.
Y/N whines helplessly, clinging to Billie’s forearm.
Billie kisses her jaw, her cheek, the damp skin beneath her eye, whispering into every kiss as her hips move in a slow rhythm.
“I’ve got you.” She breathes, thrusting in again, the words melting into the motion of their bodies. “You’re doing so good for me.”
“I know it’s a lot.” Her hips grind deeper, gentle but unrelenting.
“I know, baby, I know.” Her hand runs soothingly along Y/N’s stomach as another quiet sob catches in Y/N’s throat. “I’m right here.”
Y/N is shaking, overwhelmed, her moans spilling into the pillow as Billie fucks her through every aftershock. Tears slip again down her cheeks.
Billie kisses them away one by one.
Her hips keep moving—slow, deep enough to pull another choked whimper from Y/N’s lips.
“So perfect.” Billie whispers, almost in awe. “So sensitive for me tonight.”
Y/N’s voice cracks. “Billie, I—I can’t—”
“Yes you can,” Billie moans softly against her ear, her own breath catching as she thrusts deeper. “You’re okay. You’re safe. Let go for me.”
Y/N tries to speak, but all that slips out is a high, thin whine—her whole body clenching hard around the strap.
She breaks. Her orgasm hits fast, overwhelming, her hips arching back into Billie’s, her fingers clawing for something to hold. A long, choked sob falls out of her, helpless and shaking.
Billie’s breath stutters. Because she can feel it.
She can feel how tight Y/N is gripping the strap. She can feel every pulse of her orgasm pulling Billie deeper.
“Oh—” Billie gasps, her voice cracking hard. “Baby—God—”
She tries—tries so hard—to stay gentle, to keep whispering her through it, but her hips falter, her breath catching in her throat as heat coils brutally low in her stomach.
“Oh, angel.” Her voice shatters against Y/N’s ear. “I’m sorry—I’m sorry, I’m trying but you feel so—”
Another pulse grips the strap so tight Billie’s eyes slam shut.
It knocks the sound right out of her.
A moan—loud, broken, desperate—tears out of Billie’s throat. She buries her face against Y/N’s shoulder, panting, shaking, her hips instinctively pressing forward in small, desperate thrusts.
Y/N cries out again at the sound—Billie’s moan hitting her like a spark—and her orgasm doubles back on itself, tightening hard around the strap, dragging Billie even further into her own.
“Fuck, Y/N—” Billie gasps, voice wrecked. “She’s—you’re so tight, baby—”
Her moans melt into Y/N’s ear, breath hot and shaking against her skin, every sound rumbling right through Y/N’s body.
Billie tries to soothe her through it, even as her own pleasure overtakes her.
“It’s okay—” She whimpers, hips trembling. “I’m right here.” Another moan slips out. “Cum for me—cum with me.”
Y/N sobs—her entire body clenching around the strap, overwhelmed by how hard Billie is falling apart behind her, how Billie’s moans tremble against her ear, how her voice breaks each time she tries to soothe her.
Billie’s orgasm hits her all at once.
Her hips jerk, her breath catches, and a low, wrecked moan spills into Y/N’s neck—long and unrestrained and so sweet it makes Y/N’s whole body tighten again.
The strap pulses under Billie’s grip as they both climax, their bodies shaking into each other, Y/N gripping Billie’s forearm, Billie holding Y/N against her like she’ll never let her go.
Y/N spasms around the strap a final time, and Billie cries out softly, almost whimpering, the sound so raw with pleasure it sends another wave rolling through Y/N’s exhausted body.
They shake together through the last of it, breaths tangled, limbs trembling, Billie whispering broken, breathless apologies and praises into Y/N’s skin.
“So good… so good for me.”
Her voice is warm and cracked and unbearably sweet.
And the strap is still buried deep inside Y/N, both of them pulsing around the moment—unable to move, unable to breathe, unable to be anywhere but right here.
