About a year ago I was doing this girl...I thought my performance that night was pretty good. Went to the kitchen, when I came back she was orgasming and rattling on the bed by herself with a rabbit between her legs....hope that answers your question,
....and another time my ex went out on a girly night, I stayed in, when she came back her friend was crashing at ours, I woke up to the toilet at 5 am or so and she was still awake on the sofa on her Iphone and using my GF's rabbit under the duvet.
From what I know all normal women do so at some point....or atleast the women who come into mylife, perhaps I'm partly to blame dunno and don't care.
