Charlie Dean’s dad recently remarried, and now this American has learned that he has not one, but two stepsisters. Kate Rich and her adopted sister Lady D are eager to meet their American stepbrother when he comes to visit. Both girls are immature, so when their parents go away for the weekend they leave Charlie in charge of them. Rather than obey Charlie’s orders, Kate and Lady D decide to just do whatever they want in an effort to get him to fuck them.
The girls start their plan by taking a bath together. Naked in the tub, they splash each other, pinch one another’s nipples, and generally make a ruckus until Charlie comes in to tell them to cut it out. He wants to get dinner, not wait on the girls messing around with each other in the bath. When he marches them out of their bedroom and tries to get them to get dressed, the girls stand around naked until Kate steps forward and pulls Charlie’s pants down. The next thing he knows, Charlie has both girls on their knees in front of him, taking turns sucking his cock and balls and enjoying their mouthfuls of dick.
Taking advantage of Charlie’s confusion, Kate and Lady D lead him to bed. Lady D gets onto her back so Charlie can give in to their urging to slide on home into her twat. Kate guides Charlie until he’s right where they want him. Then she climbs onto Lady D’s face, riding her stepsis as her twat grows nice and juicy. When Kate is dripping with excitement, the girls switch places so they can each enjoy themselves further. Then Lady D gets on her knees for Charlie to give it to her doggy style. Charlie delivers the climax Lady D is craving, so she hops off to let Kate have a turn. Kate pushes Charlie onto the bed so she can climb aboard for a stiffie ride that really gets her rocks off. Only after both girls are finally satisfied do they combine their forces to deliver an orgasmic blowjob so they can share the treat of Charlie’s cum.
