Ty was surprised at first by Lisa's battery low status. He hadn't really considered it when he turned her into a fancy sex toy. But since she was no longer human, and had no digestive tract, it made sense that she'd need some power source.
He set her featureless black ovoid of a head on his desk. It wobbled a bit, but apparently had a weight distribution that prevented it from rolling. He plugged a cable from his phone charger into her USB-C socket, and was rewarded by the low battery icon appearing again, then being replaced by a charging symbol, a battery outline containing a lightning bolt.
He was feeling hungry himself, and tired. He decided to go downstairs to the kitchen, but first he had to do something about the huge pile of his cocks. There was no way he could carry, or drag, all of that with him. He sat in his desk chair, started decreasing the length and girth of his cocks, watched Lisa's charging symbol pulse, and zoned out.
