Serena couldn't hold on for much longer. She had forced herself to stop.

Serena knew the camera was still filming her, that the 3Dio was still recording everything to her laptop, but it didn't matter any more. She was mentally clinging onto the last strands of her sanity as she remained leaning over the table, holding herself up by gripping the edges of the table beneath the black cloth. The table quietly rattled—heard through the microphones buried in the ears of the 3Dio.

Then, something unexpected happened.

Though Serena had shut her eyes and was presently only able to focus on her breathing, her fingers gripping the wood to the point of digging her nails through fresh wood pulp, she could ear something. It came as a small sound, but it slowly grew to overtake everything she could hear—it was a gentle, wet sound that kept growing. Serena's eyes opened in desperation to look at the left ear—the exact ear she had rubbed lotion onto moments earlier. She watched as a thick glob of white, creamy lotion slowly trailed down from the upper ridge inside the ear to a lower ridge, covering it and spreading across it, the layer of it beginning to sink down and threaten to drop into the inner crevice of her ear.

Serena's whole face shook as she fought to hold on, looking on and hearing the overwhelming sound taking over her ear. She then shut her eyes and forced herself to take the sensations.

Serena knew she couldn't hold on any longer. It was over. She had to succumb to the pleasure at some point, and she decided to throw herself over the threshold.

The rational part of Serena's brain had shut down and was trapped in the sensations of pleasure. She was now on reserve energy, her instincts the only part that drove her. She grasped for the 3Dio in one depraved move, holding it close to herself, and forcibly bring her lips to it.

Then, slowly, Serena dragged her tongue into the crevice of the right silicone ear, licking at the inner earhole. It made her burst.

An eruption of tingles started at the very front of her skull, at the very front of her forehead and rippled out. She then felt as every single hair on her head burned with the most intense eruption of euphoric cranial pleasure she could ever know, burrowing it's way through every microscopic pore in the skin of her scalp to then blow out, the sensations expanding and rubbing pleasurably against the skull. It then moved through her face, moving down through the bone that made up her face and buzzed with a thick pleasurable intensity, making her skin radiate with the pleasure.

"A-Aaaahhhh~~!" Serena gasped out, her hands suddenly cupping and clamping onto the round ends of the 3Dio. She gnashed her teeth together, feeling the pleasure burn through her whole upper body.

It was a full-fledged brain orgasm.
