Riley Star, blindfolded and nervous, follows her sorority sisters' instructions. She kneels before Scott Trainor, her step-grandpa, thinking he's a stranger. Her wet, inexperienced mouth wraps around his throbbing cock, causing him to groan. Riley's first time continues on the bed, her petite body bouncing on Scott's lap as she takes his hard cock deep inside her. Her blindfold falls off mid-thrust, revealing Scott's identity, but Riley, lost in the heat of her first hardcore encounter, keeps going until they both climax, marking her initiation into the sorority.
