The characters in this story are all over eighteen and the age of consent, sex if it happens is consensual. UK English is the rule if the spellings Mum or colour annoy you, don't go any further, for the rest enjoy.

Jack and Chloe snuggled up on Chloe's bed. Chloe languidly stroked Jack's dick, as he lightly caressed her breast.
"Jack, this is really nice, but do you want to go further?"
"Travelwise or what?"
"No silly, do you want to actually make love, I mean it's been so nice just being naked and touching each other, but I sometimes wonder what it would be like to actually go the whole way."
"Oh! really, well yes I've thought about it, but, well, it's a big step from just being happy nudes and helping each other out to being lovers."
"Would we be lovers or would it just be sex?"
"You mean a lust not love kind of thing?"
"Pretty much! what do you think?"
"Little Sis, I can't just poke you and then walk away when we get back, it's not something I'd be comfortable with, how about you."
"Jack I love you so much, and I think it's more than just because your my cool older brother, but, I have so little experience I really don't know."
"Well in that case, we can't go any further, it's like any relationship, until your sure don't do it, okay?"
"OK, if you're sure and it's not something that's going to come back and bite us."
" Chlo, what's more likely to bite us is to leap on one another and then find out it's only lust, that could destroy us and M & D."
"Yea you're right, cool, mmmm, shall we go to the beach or just lie here?"
"Beach, but let's just lay back, I'll stop teasing you if you stop teasing me, when we calm down, we dress and go down to the beach."
"OK big bro."
They lay together but moved their hands from intimate contact, the warm sun bathed the room and they drifted off to sleep.
"Ahem, I assume you have a reasonable explanation for the fact the pair of you are naked in bed together?" The familiar voice was just feet from the bed.
"Jack! Chloe! what the hell's going on?" said another familiar female voice.
"Mmmum? Dad?" Chloe opened an eye then both, then sat up and shook Jack.
"Jack! oh boy! I think you need to wake up, you are not going to believe who's here."
Jack opened his eyes and gazed across the bed, smiling he waved a hand, "Hi Mum, Hi Dad, when did you get here?"
"Just now, but will you kindly explain why you're both bare arse naked in bed together?" Dave Ashton glared at his son, trying hard not to look at his daughter, he half turned to his wife, "Rose can you take your eyes off his dick please?"
"Dave, I'm just admiring my two beautiful children, wow, have they grown up!" Rose Ashton exclaimed then reddened as Jack's dick twitched and began to stiffen.
"Ooops sorry Ma," Jack said trying to cover himself.
Chloe took the opposite course of action and untangling herself from Jack stood up in front of her father and mother.
"It's so lovely to see you, are you staying, if so come to the beach, we've met a terrific Spanish family, they'll really enjoy meeting you." she smiled sweetly then popped a kiss on each of her parents cheeks.
"Cut that out young lady and cover yourself up, I shouldn't be able to see you like this, much less should you be seen like it by your brother, now what is going on?" Dave actually stamped his foot, which made the others laugh. Feeling stupid he began to laugh too.
"Alright, calm down, but please tell us what's going on, are you two sleeping together, come on?"
"Dad," said Jack sitting up and looking at his parents, "I'm not going to lie about this, yes we've slept together, but no we're not, errr, sleeping together, as in sexually active, ok?"
"OK, well yes and no, I mean why do you need to sleep together, it's hot out here and I would have thought you'd want some space and stuff." Dave trailed off and looked at Rose, whose amused expression ruffled him. "This is pretty serious you know."
"Okay Dad, we'll sit down and discuss it and tell you everything, well what little there is to tell, but just hear us out." Look there's a lovely balcony with some loungers and chairs, I'll get some cool drinks, see you out there."
He nodded at Chloe, and ran his hand over her firm buttocks as he passed on his way to the kitchen.
"are you going to put some clothes on?" his Father yelled at his retreating body.
"NO!" can the response from the hallway.
Chloe took her Mum and Dad's hand and walked them through to Jack's room and out onto the Balcony.
"Can anyone see you out here?" her startled Mother asked, as Chloe leaned over the rail and looked down to the small pool in the backyard.
"No, well no one's whistled or shouted. I can't see the other Villa's and I assume they can't see us."
She sat on the lefthand side lounger as her parents sat on the two upright folding chairs. Jack appeared with a tray and four glasses, together with a small ice bucket and several drinks cartons.
He placed this carefully on the small glass table and sat on the lounger, swinging his legs across he lay back on the lounger, his semi hard dick hanging towards his thigh. Chloe rose and began to ask everyone what they wanted. Having sorted the drinks she sat herself on the lounger and then lay back stretching her legs out, then opening them slightly, a small pearl of moisture visible on the lips.
"Chloe, please, I'm you're Dad, I shouldn't be seeing you like this, will you put some clothes on?!
"No, it's okay Dad I'm comfortable like this, sorry if that's embarrassing you."
"OK now will you please both just tell me what the hell's going on?" Rose stared hard at her children, then smiled.
Jack swung his legs round and moved over to Chloe, he tapped her legs and asked her to budge up. They sat together arms round each other and told their parents the story of their time in Spain. Rose nodded and smiled, Dave tutted and frowned. Finally they reached the night before's events and brought the story up to date.
Dave, stood up and opened his mouth, but no words came out, instead he stared at the door to the bedroom. It swung open and Maria appeared.
"Hola! Jack, Chloe, Oh sorry you have friends round," she went to duck back inside.
"No, no Maria, these are our parents, Dad, Mum, this is Maria, our cleaner and our friend."
Maria said hello to the two staring adults.
