I’ve been trying to get my wife to play a version of this for awhile. I call it “who’s dick is it.” Almost got her convinced that it would be fun.
Guess who?
I suppose that would work. Loud music is a good coverup, too.
Yeah ear plugs probably is not a bad idea too. but if the participants actively try and confuse the situation say by talking just a little and then switching sides just before one moves in and make it obvious that they are coming from the right or left again that can create the necessary fun of figuring it out.
Whenever we've done this it was pretty easy to figure out who was where just based on the sound of their breathing. If you really want to be unaware you probably will need earplugs along with the mask.
This game works best with bi-sexual or bi-curious playmates. You need a good blindfold no peaking that will ruin it then put the guesser on the bed or in a chair and have the rest perform on them orally and they need to guess who is the who. Works best when the players can arrange themselves making it harder on the guesser especially if the one doing the guesser has a partner if that partner is will to try new things he or she hasn't done before leaving their partner confused which position they were in.
This is great for Bi-Curious males who have never had their cocks suck by a guy before, because with the blindfold they realize that without knowing when the guys was sucking them they loved getting their cock sucked by all players and then they figure out it isn't their dick that has a problem with it but their own mind.
