When Frisky has a boyfriend, she vanishes. Yeah, she brought the last one over once or twice, but when she doesn't have one, she visits pretty much weekly.
The friend you're referring to, that strangely we haven't named yet, has had one instance of changing her clothes. Frisky has showered, been naked and had various forms of sex on multiple occasions.
You apparently missed the episode on Sept 26th, where Caroline showed Frisky how to use a vibrator.
She looked like she was considering things when they went to bed, but Elli was too wasted so she just cuddled with her. She was also a little camera shy, so that probably was a factor also.
Yeah, only time there is excitement is when the sister visits. Other than that, they just sit around playing video games and have sex once a week or two. No social life whatsoever. Jade started off strong, looked like she had a little bit of a kinky side to her with outfits and such. Unfortunately, Alberto sucked the life out of her and now they are in a doldrum of coexistence, it seems.
