She asks you to lay down so she can see her big brother's big dick. It's much nicer than her ex's. Your sister takes of her clothing and lets you admire her perky young breasts and beautiful bubble butt. She slides her perfect natural breasts up and down your shaft and uses both hands to squeeze out a load of cum from her big brother. She's really good at this! After teasing you with her round ass, she straddles you and rubs her wet pussy all over your hard cock. You're almost there, her pigtails bounce as she pumps a huge load of sticky cum all over her belly and her pussy. Don't tell anybody!
