Approaching Miss White, the Dean stood between the bound woman's legs, letting the strap-on fall onto her stomach so she could see its relative size. It extended well past her belly button.
Miss White swallowed, her eyes bugging out slightly. Surely the Dean would have some mercy on her, not tear her up inside? She opened her mouth to plead for leniency, but she just couldn't do it; she still had some pride left. What was going to happen would happen.
The Dean pulled her hips back, letting the giant bulbous head slide down Miss White's pelvis and come to rest against her puckered, hungry pussy lips. Leaning forward, the Dean braced herself against the table with hands on either side of Miss White's torso. In this stance she would be able to both watch the dildo go in and see the look on Miss White's face as it happened.
Jodie, meanwhile, took up a position near the head of the table. From there she had a good view down between the two women, past their breasts, to where the enormous phallus was poised at Miss White's entrance. Miss White took a deep breath, exhaled it, and tried to go limp; she was as ready as she'd ever be.
The sound she emitted when the head pressed into her surprised everyone in the room: It was high-pitched, piercing, entirely unlike any vocalization she normally made. It was followed by a low, guttural moan of the deepest pleasure. Already Miss White was as full as she could remember, and as the strap-on slid deeper into her, her eyes rolled back in her head and suddenly she was coming — trembling and crying out, pulling futilely at her bonds.
As the intense climax ebbed, a great sense of calm and well-being washed over her, then was quickly replaced by a new sense of urgency as the dildo continued to push up into her. She felt like it was pressing into her stomach, trying to work its way up to her chest, and still there were several inches left to go. Just when she thought she was about to be split in half, the Dean reversed direction and began to slowly pull out.
Miss White felt the strap-on slide out of her until just the head remained inside. Her pussy was throbbing and her heart was pounding, but she felt a certain sense of relief. She'd taken more than she thought she could and survived. But the Dean's second stroke was harder and deeper, and Miss White felt a sweat break out on her forehead.
Jodie, watching, began to touch herself. At some level it was appalling to see the formidable Alexis White tied, exposed, and ruthlessly fucked. But it was also indisputably sexy to watch.
The Dean gradually increased the tempo of her thrusts, taking great satisfaction in Miss White's facial contortions and helpless, raw-throated cries. From time to time she tugged on the chain connecting the clamps on Miss White's nipples, inducing a different combination of expressions and vocalizations.
At this point Miss White entered a sort of fugue state. Everything blurred together: There was a lot of pleasure, and there was some pain; the Dean's face loomed above her, then Jodie was peering down through her glasses. The Dean was not entirely in control of herself anymore either; her eyes were blazing and her nostrils flaring as she pounded into Miss White again and again, driving the monstrous cock home with complete abandon.
When the Dean reached down and brushed Miss White's clit with one finger, she came so hard that it seemed like she might tear the ropes holding her right in half. She was still coming when the Dean unsnapped the clamp from her right nipple and pulled it off. Miss White sighed as the feeling began to return to her teat, then whimpered as the Dean's mouth closed on it.
The Dean resumed thrusting slowly as she popped off the other clamp and moved her mouth to that breast. Jodie, feeling bold, leaned down and began to suck the one she had abandoned; the Dean allowed it. After a few minutes of this treatment Miss White spasmed violently, let loose with an incoherent wail, and lay still; her eyes were still open, but she could not in any meaningful sense be said to be conscious.
When a semblance of awareness returned, Miss White saw the Dean standing near the end of the table where her head was, gloriously naked — no strap-on, no dress, just smooth ebony skin glowing in the firelight. The Dean stood up on her tippy-toes and leaned forward until Miss White's head was engulfed in her crotch. The musky scent was overwhelming, intoxicating; Miss White nuzzled her nose up between the Dean's pussy lips, coating it in the other woman's juices.
