"How are we going to get Kevin to agree to this?" Lucy asked her big sister, Mary.

"Easy." Mary assured her. "What is a guy's ultimate fantasy?"

"To have sex with one of those playboy centerfolds?" Lucy guessed.

"Wrong." Mary said. "To have sex with two women at the same time!"

"Oh." Lucy said, looking embarrased because she didn't know. "So, you think he'll go for it?"

"Oh, I know he will." Mary said with an evil smile.

**LATER THAT NIGHT**

Kevin trudged up the stairs to his and Lucy's apartment. He had had a long day and he was exhausted. When he opened the door he was shocked to find his wife and his sister-in-law lying naked on his and Lucy's bed!

"What the-" Kevin began.

"It's about time you got home." Lucy said as she saw him. "We've been waiting forever."

"What's wrong, Kevin?" Mary asked him. "Haven't you always wanted two women?"

As shocked and tired as Kevin was he couldn't stop himself from getting hard. How could he? Here was his sexy wife and his sexy sister-in-law naked in the bed he slept in for Pete's sake. Man, this has to be some dream I'm having.

But when Mary's lips met his and Lucy's hands started to unhook his belt, he knew this was no dream.

"Uh, looks like little Kevin likes his surprise." Mary said in response to Kevin's moans.

"Trust me, Mary." Lucy looked up at her sister with a grin. "He's definitely not little."

"So I see." Mary said as she looked down and saw Kevin's cock being released from his cotton prison. Her sister was right, he wasn't little at all. "Want us to take care of that for you?"

Kevin could only nod. Mary knew what he wanted though as she took him in her mouth while Lucy took off his shirt and caressed and sucked on each of his nipples. The dual attention brought him to a quick climax.

"Umm." Mary said after she had sucked him d ry. The sight of her licking her lips got Kevin hard all over again. Even more so when she said, "You taste good."

"He really does, doesn't he?" Lucy giggled.

"I bet he's a good fucker, too." Mary said with a wink at her sister.

"Why don't you lie down and find out?" Kevin suggested hoarsely and Mary did as she said.

Kevin knew that Mary was a girl who like things hard and fast so that's exactly how he fucked her. "Oh, YES!" Mary screamed as he thrusted in and out, in and out. Not once slowing down the pace.

Lucy didn't like being left out and she was quite anxious for her turn to be fucked by her gorgeous husband so she started to rub her sister's clit. This made Mary come instantly and Kevin came as well at the feel of Mary's walls milking him.

When Kevin pulled out of her Lucy whispered in his ear, "My turn."

Kevin was happy to oblige and pretty soon Lucy was on top of him impaling herself on his cock over and over again. Mary was getting turned on watching the couple so she crawled on top of Kevin and straddled his face while still facing her sister. Kevin started eating Mary out while fucking his wife at the same time. Lucy loved the expressions and sounds coming from her older sister and soon came with wild abandon. This set off a chain reaction. Because of Lucy's climax Kevin came, and because of Kevin's climaz he thrust his tongue up inside Mary's pussy harder and faster then you could imagine which in turn made Mary come with a scream.

Lucy rolled off of Kevin and soon enough Kevin feel asleep from exhaustion. Lucy cuddled up next to him watching her sister get dressed. "Thanks, Mary." she whispered.

"No problem, Lucy." Mary smiled at her as she kissed her on the forehead. "We should do this again sometime."

"Oh, definitely." Lucy giggled.

Mary smiled at her and gave her a wink before leaving.
