Head downstairs

Although the thought of catching the younger sister undressed again is tempting the risk somewhat outways the reward and Sam decides that maybe leaving the kids alone is the best idea.

Heading to the stairwell he tries to get the image of the girl - Sam suddenly realises he doesn't even know her name - out of his mind and steps out of the corridor into the living room where he realises that it won't be a problem.

Standing in front of him is Shelly, her back turned as she talks to someone else, but she has changed. She's now in nothing but an open blouse and a light blue bikini which leaves half her arse on display. Once more Sam feels his cock beginning to stir.

"Sam, hi!" Shelly suddenly says, turning to face him revealing the bikini top is just as tight her magnificent breasts looking like they want to escape. "This is Emma, the friend from work I told you about."

Sam is finally able to tear his eyes away from Shelly and take a look at the latest arrival. Emma seems to be a little more plain than either of her daughters, dressed in a thick blouse and trousers, but it's clear to see where they get their good looks, even though she must be in her forties anyone would be forgiven for thinking she were the same age as Sam or Shelly.

"Oh, um, hi." Sam finds himself turning a little red as he shakes her hand, trying desperately to not to turn and watch Shelly's body.

"I hope everything is alright for you?" Emma asks politely.

"Yeah, the place looks really great." Sam replies with a smile.

"We bought some bagels and things for breakfast if you'd care to join us, I was just about to call the kids."

"That's great." Shelly says with a smile, "but I really want to try out the pool first."

"No problem." Emma tells her. "How about you Sam?"
