Have Beth fuck Becky's wet pussy.

You turn to Becky, spread eagle on the bed. "Becky, have you ever seen a cock that big before."

Becky slowly shakes her head back and forth, never letting her eyes leave Beth's new, humongous cock.

"Becky, would you like to fuck that cock?" you ask.

Becky again slowly shakes her head. "Too big," she murmers.

"Well the only way to beat a fear is to face it" you add with a grin coming to your face. "Beth, approach the bed! Becky strip!"

Becky quickly discards the her clothing as Beth slowly walks to the bed, still stroking her cock. She walks right up to the edge of the bed and positions herself between her sister's legs. "That's a girl," you blurt. "Now slide that cock into Becky's pussy. It should go in nice and smooth, she definately looks wet enough!"

Beth then positions the head of her cock against Becky's swollen pussy lips and starts to push it in. The head of the huge, purple cock doesn't look like it will fit, but you know it will. This is the fucking that Becky has been waiting for. Beth pushes the cock in slowly, inch by inch. You can't help but moan out in excitement at the vision before you. A beautiful, blonde angel, fucking her slightly older sister on the pink, innocent bed. This is like a wet dream come true. You don't know where to look; at both sets of gorgeous tits; or the new cock slowly sliding into Becky's young pussy; or Becky's face, as she struggles between the pain and pleasure given to her from her younger sister.

You eventually set you gaze at Beth's delicous ass, straining and pulsing as she slowly fucks her sister. You notice that she has a stream of juice sliding down the inside of both thighs from her still intact pussy. Oh what a sight. What to do next.

You look at Beth's tiny, pink asshole and cannot imagine her ever being fucked in it. You could slide into that tight asshole while she fucks her sister, or you could go around to the side of the bed and push your throbing cock into Becky's pretty mouth. Decisions, decisions!
