Dilly the Dog

Amulet of Exchange: Swaps the minds of the wearer and victim, transferring the amulet magically while doing so, ensuring there isn't some repetitive and continuous exchange. If desired, the amulet also has memory and muscle memory transfer abilities that can be enabled and activated, merely requiring the mind swapper to cum in this new body to unlock the person's skills and knowledge, becoming them and whittling down the original mind's abilities in the body they've been swapped into, if that option is also pressed.

This artefact was just sitting there, magically appearing in the Jura household. It was a lovely little traditional family with a wife, a husband, a daughter, and a dog. In the order introduced, their names were Cynthia, Isaiah, Eleanor, and Dilly. Cynthia and Isaiah's love life had grown a bit stale, but they were still very intimate and loving, always acting erotically and romantically, to Eleanor's embarrassment. As for Dilly, he was a very horny dog ignored when Cynthia and Isaiah got intimate. Because of unsatisfied desires, Dilly always imagined Cynthia when he got horny and started humping things, knowing in his head that Isaiah was a lacklustre male. Still, Dilly was the dog, and Isaiah was the master, so Dilly did his part, fulfilling his duties as a dog. But then Dilly found the amulet, and as he touched it, it activated.
