my friend and I wanted to do a husband swop. The guys agreed and we were able to do it without condoms. I've never had two men's sperm in me in one night nor had my friend. We stayed with them and fucked in different rooms. When he back to have me he had to put his dick in a cunt full of the other guy's come. He seemed to excite him . My girl friend found the same. They said it was more exciting for them that way. I think we did too. Done a few times since.
