Adult only. Private by design.
Cuckold vs hotwife

People use the two words for different agreements. Say the one you mean, before anyone drives over. A joke in the invite is how the wrong guest arrives.
The short answer
A hotwife night, as this site uses the word, means she plays and he is part of the yes. He may be in the room. The night is still something they both agreed to.
A cuckold agreement, as people use that word, often means he is watching or sitting out on purpose, and that is the plan. It is still a guest the couple invited. It is not a surprise in the kitchen, and it is not a script the room invents.
Your host invites friends. The host invites friends they'd love to have there. One private link. Adult only. Private by design. You confirm you are 18 or older.
How to tell them apart
Write one sentence the guest could repeat.
- Hotwife: she plays, he is in the yes, and he knows the ceiling.
- Cuckold, as guests use the word: he is watching or sitting out on purpose.
- Both partners agreed before the link went out. Polite is not a yes.
- The other person is a guest with a name, a link, and a no.
- If you would not say the word to his face, do not put it in the invite.
The guest is not a prop
He or she gets the ceiling in plain words: soft or full, same room or a closed door, watching or joining. They can decline. A couple who only agreed to be polite should not send the link.
A bull is a narrower invite: a man the couple asked to play with them. Do not stack the words. Use the one you mean, and link the page that matches.
During the night
The line you wrote is the line. A match is permission to talk and to ask. It is not a schedule, and it is not permission to humiliate someone who did not agree to that.
Anyone can stop. Tell the host if the room will not hear it. No photos. No recap in the group chat. Monday does not get the story.
