For a girl to be fucking another girl with a big dildo is HOT... it's a fun turn on, cuz you get these crazy testosterine desires. So its like a guy fucking a chick... it's a mental kind of arrousal, and even yet when it gets my blood pumping, it makes my pussy very horny, wet and clenches in violent pains wanting to get fucked too. Moaning relieves a small amount of tension.

For me anyhow.
