Mutual masterbation is when two or more males get together in a room and masterbate infront of each other. They may get naked and sit in a cirle and masterbate the person to their left or they may just all masterbate themselfs at the same time. There are many variations.
When two friends meet in a room and they strip off and then masterbate each other until they ejaculate, this is an example of mutual masterbation.

Get the mutual masterbation mug.
Where you sit on your hand till it falls asleep and then you use it to jackoff so it fells like someone else jacking you off and you imagine some woman's jacking you off.
