Girls in their late-teens to 20's who utilize streaming services such as Twitch in order to flaunt their giant breasts to a large following, mainly consisting of horny men and 12 year old's who have never masturbated before.

Some titty streamers may also place their leg on their chair in order to demonstrate how gorgeous they look.
