Home alone and jerking with sexy Riley Reid

Your car broke down and you go to a nearby house to see if you can use their phone. A cute girl answers the door and tells you she is home alone. Since you don't look too scary to Riley, she lets you in. She invites you into the living room and you find out she was home and is somewhat naive. Riley seems pretty interested in older men, she tells you, and she invites you to hang out while you wait for the tow truck. She seems nervous, but friendly. This 18-year-old tells you she has never even kissed a guy before, but she works up the nerve to ask to see your dick. This is sort of like those Penthouse stories you have read, but it is happening to you for real!! Riley takes off her shirt and when she sees your cock, she is shocked at how big it is. When she takes of her bra, her tiny titties make your cock grow harder. She doesn't know your name, so she calls you "Mister" and you like that.
