Switcher party

When Thomas heard his friend was having a swinger party, he was excited. He showed up with his girlfriend without telling her what the situation was. However, he misheard, and it turned out that it was actually a switcher party. When they showed up, they each swapped bodies with two other guests at the party. Thomas ended up in his own girlfriend's body but was unsure of who his girlfriend had swapped into. He waited on the couch for her, so that they could leave and swap back. Hours passed as he consumed a few drinks and then a few more. Eventually he passed out. When he awoke the next morning, he noticed a few other guests who had also passed out, his own body among them. He was startled by the front door opening with his friend Philip, the party's host, emerging. Philip was shocked when Thomas told him who he was and then told him with a frown that all the people who spent the night would be stuck in their new bodies forever.
