Lisa's Revenge (Mr. Burns last hope)

Bart opened his eyes in the dark. Something was wrong. His arms were pulled tight over his head. He tries to move and can't. "That's okay," a voice speaks up from the side of the bed, "Struggle all you want. I don't believe you will get free of ropes I have secured you with." He turns his head to the side and sees Lisa standing next to the bed in a short nightie. He tries to speak and realises that he has a gag over his mouth. He notices that there is a slight bulge in the front of her nightie.
She walks down to the end of the bed out of his line of sight. "Remember all those times you raped me in the ass, bart?!," She exclaimed, "I haven't forgotten. I think it is unfair that you never got to experience the sensation of having something stuck in you. Don't worry though. That is why I am here tonight, brother." The bed sinks down under her weight as she climbs onto it. Bart feels his pajama bottoms jerked down to his ankles in one swift motion. He locks his knees together in sudden understanding of what she wants. He tries to beg her not to do it but the gag keeps him from making any coherent sound. Bart feels something jelly like ooze down his buttcrack. He feels something pressing into his sphincter and realises that it is Lisa's fingers. Tears dribble down his cheeks as he weeps in shame. Lisa jams her knees between his legs and, after a few minutes of struggle, pries his legs apart. Bart feels the tip of something warm prod between his butt cheeks. (This can't be!)Bart thinks to himself.(It feels like flesh). He feels her bend over him and bites down on the gag in pain as she enters him.
Lisa moans in pleasure as she pushes her borrowed cock into Bart's butthole. (This is the most fantastic feeling I have ever had). Lisa thinks to herself.(No wonder he likes to do this to me). She pushes in a little bit and then pulls back halfway. She tries different angles of pushing the hard shaft into him. First she pushes the dick straight down and then she tries pushing in at an upward angle. As she tries these different positions his tight hole loosens up on her. She licks the tears from his cheaks as he lies still under her. A small orgasm passes up from her crotch up to the base of her neck. She increases her pumping pushing in farther than before. "Oh God!" She moans against the back of his neck trying to muffle herself, "Bart, this is the most wonderful feeling I have ever had! I am not mad at you anymore. I can see why you would want to do this to me over and over again." There is only the sound of the bed springs sqeeking and Barts sobs for a few minutes and then Lisa's moans rise a little as she empties Mr. Smith's cock into Bart. She collapes onto Bart's back in exhaustion as seamen leaks out of the shrinking dick in Bart and out of his crack.
Afterwards she unties him. She is not afraid that he might tell. She knows he won't. Who would believe him anyways?


As days go by Lisa continues sneaking into Bart's room and raping him in the ass. At first Bart tries to lock his door to keep her out but his door to the bathroom that they share does not have a lock on it. He tries to stay up all night to keep her away but falls asleep each time around midnight. Then on the fourth night of her raping him in the ass someting strange starts to happen. As Lisa is pounding him in the ass he begins to get a hard on. He burries his face in his pillow in shame as he realises that he is starting to like it. As she pushes down on him with each thrust he feels himself get more and more stiff. He moans softly into his pillow as he cums against his stomach and his Krusty the Clown bedsheets. A few more thrust later Lisa empties her seed into him. She does not notice that there is a little extra seamen on the bed this time.
