Why not both?

Maximus briefly pondered his situation.

Two days ago, he'd been overweight, underpaid, damn near a virgin, and masturbating to implausibly proportioned fantasy versions of his boss, a co-worker, and any number of other unreachable women.

Today, now, he was fit if not cut, had a cock worthy of myth, balls bigger than any man had possessed before, and had Barbara on her knees in his cubicle, having abused her authority to clear the office just so she could drink his cum.

If this was his fantasy, he was going to push the boundaries for all they were worth. What would he have imagined himself doing in this situation, had even his fevered dreams been capable of creating it, before now?

Cum down her throat, giving her what she desired? Hold off and make her work for it?

Fuck making decisions like that.

He'd do both. He'd cum so much down her throat she wouldn't need to eat for 2 days. He'd still be just as hard afterwards, and she'd either keep sucking or find another way to continue. Or he'd find another willing partner. One wasn't enough for fantasy Maximus. They didn't have the stamina to keep up.

With a primal grunt of pleasure and effort, he reached forward and grabbed Barbara's head, gazing into her eyes as they widened.
"I'm about to fill you up. keep sucking, and swallow it all."

He thought she might have actually orgasmed a little at that, but he couldn't tell anymore, having lost all ability to focus on anything except thrusting his cock as far down her throat as it would go, unleashing a torrent of cum from balls which were clenching heavily below it. He'd no idea how long it went on, but Barbara slapping his leg jerked him out of the fugue state, and he released her head from his grasp.

*Gasp, pant, gasp, etc*

*splattering noise as the final weak shot of cum hit her in the nose.*

Maximus looked at Barbara kneeling before him, her massive tits heaving. He couldn't tell under the sweater, held outward slightly by the projection of her recently expanded tits, but if he was a betting man, he'd say she had gained a few inches around the waist, simply by being so full of cum. Certainly, she seemed to be rubbing her belly in shock and/or pleasure, he wasn't sure.

Also, yep, his cock was still hard as some metaphor, ready to go again. He could even hear soft gurgling noises from his nuts, smaller now, but filling once more as they prepped for action. Grabbing one of the protein bars he kept stashed in his desk, he washed it down with almost a liter of water, staring down at the shell shocked Barbara as he did so.

He'd need to stock more food and water if this kept up.

"So, what next?" He gestured at his cock. "Can you handle another round?"
