In return, Alexa buries her face between Elena's thighs to feast on her trimmed twat. That's when Scarlett wakes up and realizes that it's hot as hell to watch her cousins go at it. Sliding her own panties aside, Scarlett masturbates as she watches Alexa work her mouth.Happy to include their cousin in their sex games, Elena and Alexa welcome Scarlett into their ring of passion.
