Hahahaha...man that’s the nature of the game in a gangbang. I’ve never done the DP yet but I wouldn’t have a problem.
The way I look at it when you’re having group sex, you need to discard all inhibitions and hang ups. Everyone is trying to please and be pleased. There will be random sounds, smells and liquids. Now is not the time to get all squirming about cum. Clean it off and move on. I am perplexed in group sex where individuals get so up tight. I always wonder why are you here? if you have a prob with these close quarters ask to be alone with the woman.
