If you new find a guy that is gentle and willing to guide but move at your own pace, some can be pretty pushy. Go as far as youre comfortable but pushing just on/past your comfort zone.
Yes it is fun when a couple let you join in with them and when no-one has a problem if your manhood fulls into the other males mouth and if he is happy to let you taste his wifes juice from his tool..... curious enough to be naked with a husband and wife
i had a great 1st experience of this when i was having great sex with a guy's wife with him watching when all of a sudden he shoved his rock hard cock into my mouth... very exciting
