Your new girlfriend and your evil twin brother

Stella met you two months ago at a football game where she was the cheerleader captain. Her stunning athletic performance and gorgeous good looks made you instantly smitten. That night, you two became lovers. During a recent college break, you took Stella to meet your family at your parents' house. There, she met your twin brother Bryan, who looked just like you except for some subtle differences she couldn't quite put her finger on. Little did she know, Bryan would soon take advantage of her naivete and inability to tell the twins apart to have his way with her.
