She tries to lift her ass higher in the air, her face resting against Grant's neck as he breathes encouragement into her ear.
"That's a big cock, love, but look at that. You're taking it perfectly."
"I am?" she gasps as it slips in a little farther.
Caleb's hand rubs soothing circles across her ass and lower back. "Just breathe sweet thing, that's right, you're doing so good.”
Caleb fucks her with the toy and she expands around it. The stretch is intense but exhilarating, and pain morphs to overwhelming pleasure. She feels dizzy, gripping her mate for dear life as her other rocks the dildo into her. "Do you think you can come around this?"
"I don't—ah." Caleb must’ve hit a button on the dildo because it clicks to life, vibrating inside her and shaking her entire cunt. It moves, too, she can feel it thrusting inside of her, eliciting the most inhuman noises from her mouth.
“How’d we get such a perfect Omega?” Caleb asks.
She moans again, long and loud in Grant's ear, and feels his dick twitch against her stomach.
"That's right, keep feeling that.” Grant licks up her neck, tasting the salt and sweat there. Alice thinks he might complete their mating bond right then, but instead, he peppers kisses over her.
Her pussy pulses around the shaking toy that thrusts into her G-spot and she's caught off guard by the orgasm that sweeps over her. A cold sweat covers her skin as she comes, and comes, around the toy, tightening around it as if trying to push it out of herself or suck it in farther, she's not sure.
"Good, good girl coming for us like that," Grant mutters in her ear. "Our perfect girl."
"Alpha," she pleads, and maybe it's the desperation in her voice, but they don't make her wait. Caleb pulls the toy from her slick hole and Grant readjusts her so that she's higher on his body and his cock is lined up right at her entrance.
There's no preamble before Grant is sliding home in her. He's less thick than the toy was, but warmer and she is so addicted to the feel of their cocks inside of her that it feels like a slice of heaven.
Alice looks over her shoulder for Caleb, who is rubbing something on his cock, watching intently as his mates join together.
"You'll…be in my," Alice breaks on a moan as Grant pushes faster into her cunt. "In my ass?"
"No, sweetheart," Caleb says. "Not quite."
Alice's face twists in confusion, but Grant's knot almost breaching her entrance makes her breath hitch.
Caleb inches between their legs and rubs his slick head between her ass cheeks and down to where Grant fucks her from below.
Alice understands all at once what they plan to do: both of them inside her.
She groans at the thought and gasps as Caleb slips two fingers in alongside Grant's cock.
"It won't fit," she breathes. "There’s no way you both can fit."
"We will," Grant says. "We've got you, baby."
Grant steadies his thrusting to a stop and all three of them hold their breath as Caleb lines himself up. With excruciating slowness, he presses his cock against Grant's in her hole, stretching her wider than the toy, wider than either of their knots, filling her until she feels she might faint at the sensation.
"Breathe, sweetheart," Caleb says and she and Grant both take labored breaths. As she relaxes, Caleb can slip in farther, and after a pause, he begins to thrust. “That’s unreal. It’s. . . fuck.”
Grant and Alice both moan, while Grant's mouth is on her neck again, sucking and nipping and licking.
"Do it," Alice whispers, "Please, Alpha."
Grant's hips pulse, pumping just once deeper into her as his teeth bite down on the soft part of her shoulder, completing the mating bond in one glorious moment, connecting them indelibly forever. By the way his hips jerk, Alice knows he's coming in her as he does, and through the bond she can feel his extreme pleasure, only heightening her own.
She feels more than that, though. There’s his tenderness and love, the protectiveness he feels, and devotion to both her and Caleb, it's all there in the bond, and he can feel all of her just the same.
Unlatching, he licks at her neck, sealing the wound that already tingles as it heals to a light scar. They breathe together, hearts thundering against each other, and kiss until Alice is dizzy and her chin is bright red from his stubble.
When they pull apart, Alice turns again to study Caleb whose face is screwed up in concentration, like he's trying his hardest not to go into a rut.
