A murmur rose from Yvonne’s chest. “The sounds you make are so delicious. I could listen to them all night. I could do this all night, make you scream, over and over.” She fixed her eyes on Ruby’s. “And since I have you bound and at my mercy, that’s exactly what I’m going to do to you.”

Ruby shuddered, the hairs standing up on her skin. It was clear that Yvonne meant her threat. Yvonne grazed her lips down the side of Ruby’s neck, biting her shoulder, causing Ruby to moan. She grabbed a fistful of Ruby’s hair, tugging it firmly, coaxing a pleasured hiss from Ruby. She raked her fingers down Ruby’s front, leaving faint red lines on her breasts and stomach.

All the while, Ruby squirmed and bucked, the panties muffling every sound she made. Pleasure? Pain? She couldn’t tell the difference anymore. It was all so exquisite. She was intoxicated by it all, and by Yvonne, her Mistress. She wanted Yvonne to take her, claim her, use her until she was Yvonne’s so completely that all her edges dissolved away and the two of them became one.

“That’s it,” Yvonne said. “Surrender to me.”

As Yvonne continued to ravish her, Ruby closed her eyes, letting herself fall into a familiar trance of submission. She relaxed into the flow, trusting that Yvonne wouldn’t hurt her, that she would keep Ruby safe, no matter how vulnerable she was.

As she let go, all the sensations she was feeling amplified. The pressure and roughness of the ropes binding her wrists and ankles. Yvonne’s scent, a perfume tailor-made to make Ruby weak. Yvonne’s fingers, pinching and scratching and teasing Ruby’s sensitive skin. The satin of Yvonne’s lips as she assailed every inch of Ruby’s body with them.

Yvonne slid her hand between Ruby’s thighs, dragging her fingers over Ruby’s folds. “You’re so wet. So ready for me.”

Ruby quivered. Yvonne pushed a finger inside her. It slipped in easily, piercing deep, but not deep enough. Ruby held back a whimper.

Yvonne drew away. “I’m ready for you too.”

She got up from the bed. Ruby watched silently as Yvonne pulled her blouse over her head and stepped out of her pants. But it wasn’t just a bra and panties she wore underneath. Her black boyleg briefs, embellished with lace, doubled as a harness that held a black dildo.

Ruby bit her lip. She’d felt something hard at her back when Yvonne had pushed her against the wall earlier, but she’d been too distracted for it to register. Now, the dildo was impossible to miss.

“You have no idea how long I’ve been waiting to fuck you properly,” Yvonne said.

Ruby inhaled sharply, heat flooding her core. Yvonne rearranged the panty harness, pulling it up at the waistband, before crawling back onto the bed and positioning herself between Ruby’s outspread legs.

Ruby’s breath grew slow and heavy. Yvonne took the dildo in one hand and guided it into Ruby’s slit, entering her with one push. Ruby cried out, ecstasy surging through her. Yvonne buried herself inside her, over and over, deep and unhesitating. She clutched at Ruby’s waist, her fingers digging into Ruby’s skin.
