You can ask your guests to make a nice tattoo on their partners arm. For this you will need to prepare some body paints, face paints, or body markers to decorate with. You will also need to have some towels or washcloths on hand for any cleanup. After all the guests have made their tattoos, have everyone admire each others tattoo and vote for their favorite. The couple with the highest voted tattoo wins the game. A great couples party game! So creative and fun!
