3 days later & evolution

Before Gordon knew it, three days passed, filled with fucking and lust, allowing the two to remain full, including Gordon, who periodically had meals delivered as part of his meal deal with the inn.

The restored vitality meant Gordon could continue going again and again, and their slutty natures meant Gordon's partners could keep the fun train active. However, something strange happened when Gordon and the succubus joined hands, allowing Gordon to see them both glow before changing, evolving into new forms. That's when Gordon put two and two together, realising that his restored vitality and 1.25x XP output meant that he had been creating free experience, allowing the girls to have the 0.25x XP while he continuously got back his 1x XP. With three days filled with carnal lust, Gordon realised he must have fucked them so much that they reached the breaking point and were ready to evolve.

Looking at their panels, Gordon saw that they had both reached level 20, realising that this was the first time he had in three days to stop and have a break.

Watching them transform, Gordon saw Peach and Nautica evolve into?

(Nautica is the rescued succubus; they figured out her name after she absorbed Gordon's cum and learned his language, something she couldn't do before since she is a newborn succubus that was captured before she could taste human cum)
