Sofia is a gymnastics instructor, which means you're in for a flexible treat. This 5'7" blonde from North Carolina enjoys swimming, running, dancing and chilling with her friends. She doesn't like wearing underwear, but she'll wear lingerie if a guy buys it for her. Speaking of guys, Sofia's boyfriend shot these photos for us. Sorry that the lighting isn't perfect, but he was trying to show off Sofia's long, sexy legs and her gymnastics flexibility. He obviously doesn't mind sharing his girlfriend with the world, which we think is very cool of him. "He's just not a jealous guy," Sofia told us. "We've talked about threesomes before, and he's just so nonchalant about it. His attitude makes me want to do it even more!"
