That's her toy, she said it's a Yoo. Here is the caption of her photo:
I have this feeling she's always using toys that she has become dependent on it. I want to tell her that if she gets too hooked on getting her orgasms from toys, time will come she will have a hard time getting off through regular coitus or even cunnilingus.
Anyway, have fun staring at her photos. Hehehehe.
