"After having run a fan site for Sienna for awhile now and having her as a special guest during my live cam events we saw how much the fans love her and cannot get enough," Cruz said.
"She is a natural live on cam, loves sex and has a way of making everyone feel comfortable. It's hard to find a porn star who has all those qualities. Her site is doing amazing already. Her popularity is on the radar to rise even more. Big boobs will always be a huge niche for us."
West will be live for her fans weekly starting in early February in solo, girl/girl and boy/girl special live web cam events.
Members will be able to interact with her via her message board and get access to her personal email. Members will also get access to all of her exclusive photos, videos and for free get access to all of the Fantasy Girl websites, 17 total for one price.
"Our company is 100 percent focused on live entertainment. She is a perfect fit for us and we are very happy to have her on board with us," Michaels said.
"All of Sienna's live shows will be performed on Sweet Fantasy Cams where the members get access to all the live adult stars who perform on the network. Any performer out there looking to join a live webcam network should check out SweetFantasyCams.com."
