A birthday surprise!

"Welcome home sis!" Ashley said flinging the door wide and giving her big sister a hug. Ashley had expected Sarah to arrive naked ever since she had gotten the photo yesterday, even though she knew Sarah had always been shy when things got serious. Sarah, who had not sent the message as it had been Christa borrowing her phone, expected her nudity to be a surprise, but instead found herself the one being surprised as Ashley, her 18-year-old sister, had greeted her and hugged her as if Ashley had known Sarah would be naked and bringing two naked guests as well. More importantly, Ashley was herself very much naked.

When Ashley told her guests that Sarah would be naked and bringing one or two naked friends, all her guests thought it would be a good experience to make it a birthday party were birthday suits were mandatory. Ashley hesitated briefly but decided it would give her a chance to experience Sarah's new lifestyle choice. So everyone at Ashley's birthday party, her friends, family, neighbors, etc were all naked and enjoying the freedom of it.

Sarah was stunned as she felt Ashley's bare chest pressed against her own. Before Sarah or Katie could recover enough from this surprise, Ashley turned to Christa and shook her hand, "I see Sarah talked you into it!"

"Yeah, it took most of the trip," Christa said without missing a beat, "So you decided to try it too?"

"Not just me," Ashley said sounding thrilled, "everyone! the entire party is no-clothes-allowed."

"Really!" the three girls said at the same time. Christa sounded excited, Sarah and Katie were confused.

"Yeah, come on in and see!" Ashley said pulling Sarah inside. Sure enough, everyone was naked. Sarah's parents, aunts, uncles, and cousins as well as Ashley's friends from school, her current boyfriend, her ex-boyfriend, the girls from her school tennis team, a few Sarah recognized as school teachers, the man from down the street who was the middle school principal. In short, everyone. Many guys were sporting throbbing erections, and many girls were staring and whispering to each other about it. Sarah and Katie saw Sarah's cousin Kim leading the middle school principal's 19-year-old son out of the room with a firm grip on his erect cock.

"You must be hungry after the long trip, let me get you some food," Ashley said and dashed off.

"What the hell..." Sarah said still reeling from what she was seeing and hearing.

"I kinda sent your sister a message from your phone yesterday," Christa admitted, "I told her you and Katie were now nudists and wouldn't be wearing clothes,"

"No way," Sarah said flatly, "Ashley wouldn't believe I would do that!"

"But you did," Katie said breaking from her amazement and bursting into laughter.

Sarah tried to speak but couldn't seem to find the words. Christa spoke first, "I sent her a couple pictures of you and Katie naked to convince her."

"Hard to argue when they show you that they have been running around naked outside," Sarah agreed.

When Ashley returned, Sarah loosened up and started to enjoy the party. Christa let herself be lead off by one of Sarah's male cousins and Katie talked Ashley into sneaking off somewhere when Sarah wasn't looking. Sarah, looking for Ashley, accidentally walked in on her parents having sex, back out of that room and into the one Christa was using. Deciding she didn't want to find Ashley anymore, she retreated to her own bedroom to clear her head. Unfortunately for Sarah, Ashley had moved into Sarah's old room when she left for college since Sarah's room had been much bigger.

Ashley and Katie stared at Sarah for a moment as Sarah looked at them. Katie seized Sarah's hesitation and crossed the room in an instant and took Sarah's hand and brought her to the bed. Laying Sarah down next to Ashely, Katie took turns on each of them. It didn't take long for Katie's expert tongue and nimble fingers to work Sarah up into a frenzy of lust so deep that she was no longer worried about who she saw or who saw her and just wanting to enjoy this epic party.
