Miss: Show off for them (Make you cum)

"I've never felt like this before," you say. "I just keep wanting more." You pause, looking for the right words. "Wanting to give more. I want you now, Mary, and I want Taylor again."

Taylor sighs. "Wow," she says.

Mary smiles at you and nods at the clock. "I'm sorry, Tom," she says, "but Taylor and I have to get ready to go to work. How about you lay down on your back and show us how you feel with your hand. C'mon, hon, show us."

Mary's slow, lilting voice works a spell on you. You roll over onto your back and start stroking your hard cock.

"That's beautiful, Tom, show us how you love yourself," Mary says.

Taylor rolls over toward you and watches. "That's hot, Tom. Fucking hot," she says.

"Language, hon," Mary chides. "How about you love up on yourself too."

Taylor slides her fingers between her labia and starts rubbing herself. The wet, squishy sound of your sister rubbing her clit, spreading her juices and yours around, fills your ears and makes you dizzy. Your cock throbs in your hand. But it's Taylor that reaches her climax first. By the time your cock is spurting through your hand, she's cuddled up beside you, whispering lovingly in your ear while Mary cheers you on.

Mary and Taylor disappear into the shower, leaving you alone, dazed, and shot dry, lying naked and sexually spent on Mary Forbes' marriage bed.
