When two or more people sexually stimulate themselves or one another, usually with their hands. The range of participation can be as simple as two participants masturbating in the same room at the same time without any physical contact to a group of people all stimulating one another. In the case of two participants, one partner may stimulate the other, each partner may stimulate the other, or one may stimulate both themselves and their partner.
