Family Ties/Blackmail with the video the night before were she banged Timmy.
"Hey Heather what were you doing in Timmy's room last night?" You ask innocently.
"Nothing, he couldn't sleep so I stay in the bed with him until he fell asleep." She doesn't look at all guilty with her response, not a sign of thinking whether or not someone knows her secret.
"Heather."
"Yeah Jacob."
"You wouldn't lie to me right?"
"Why would I?" She responds.
"Then why did you just lie to me right now?",
"What do you mean?" She asks nervously,
"I know what you did last night, and don't say you just stayed in the bed with Timmy.., You did a lot more than that! I know you fucked the hell out of him last night." You say a little angrily.
"God you fuckin pervert, what the hell is wrong with you, where in the world would you get that idea?"
You slide in next to her and take out a flash drive that you prepared earlier in the morning and put it into her computer. There is only one file on the flash drive and you select it. As the window opens your sister's eyes go wide with surprise as she sees the video on her and Timmy from last night. On the screen Heather has just mounted Timmy while pull her sleep shirt off, leaving her completely naked for you little brother. You reach over and shut the video off just Heather grabs Timmy's hands and guides them to her big tits. After the screen flashes off Heather closes the lap top and pushes it out of the way.
A tear collecting the corner of her eye, "Little bastard...." She whispers, "What do you want..."
"I want what Timmy got I want you naked on top of me fucking my cock." You place your hand on her thigh and she doesn't stop you as you slip your fingers into the bottom of her jean short, snaking them up high enough to find her bare pussy lips. "You forgot to put your bikini bottom on sissy.., hoping for a little one on one time with little Timmy." You chuckle evilly, "I hate to break it to you but your not the only one who has a thing for Timmy. As a matter a fact mom is probably in the back bedroom right now giving him a strip tease."
You gives you a very hurt look but wastes no time in arguing and grabs the erection that has created a tent in your sweats, squeezing it roughly before yanking your sweats down to free you cock. "Let's get this over with." She says before plunging your cock deep into her mouth.
