This is a work of fiction. It's a multi-part story and is more for connoisseurs of erotic stories and not for those looking for quick and explicit sex. It's best to start with part 1.
***
After feigning sleep and eavesdropping on my parents it was time to experience being nude properly. I yawned loudly and stretched before opening my eyes.
"Hello sleepy head!" said my mother smiling at me.
I looked at her naked body and still couldn't quite believe what was happening. "How long have I been asleep?" I asked.
"About an hour or so" said dad.
My mother asked "How are you feeling, was the drink too strong for you?"
"Maybe, I don't know, I just nodded off."
"Probably a combination of jet lag and alcohol!" laughed dad.
"Do you feel up to exploring the resort?"
I hesitated and mum could tell I wasn't yet comfortable with the idea of being naked amongst others, she quickly added "Or, we could order some room service and just stay up here for a bit."
"That sounds good and now that you mention food I'm I feeling really hungry."
Mum smiled and jumped off her sun lounger. I couldn't keep my eyes off her body and she smiled as she noticed me watching her every move. She walked into the room with her hips swaying provocatively and my penis quickly hardened. I looked at dad and saw him watching me. He smiled and said quietly "Your mother's a beautiful woman, don't be ashamed to show your appreciation!"
I blushed and turned back as I heard mum returning. She walked towards me and handed me a room service menu, she smiled at my erection and said "you seem to be hungry for more than food!"
I was embarrassed but laughed at her joke along with dad. Reading the menu made me even hungrier and I quickly chose a hamburger and chips, with my parents going for a seafood platter. Dad went inside and phoned in our order. My erection remained and I caught mum staring at it a few times before she said "Jack, don't you want to go and take care of that? Isn't it getting uncomfortable for you?"
I blushed and asked "Um, you mean masturbate?"
Mum smiled "Yes, or if you want I could help you."
My mind was racing as the implication of her words sank in. I was about to reply when dad returned "It'll be about 30 minutes."
He noticed the tension between the two of us and said "Did I interrupt something?"
"I was just telling Paul he should get some release."
"Your mother's right, it's not good to stay hard for so long."
I was blushing furiously and stood up muttering "I'm going to the bathroom."
"Jack, wait, don't be embarrassed it's perfectly normal and my offer still stands."
I was tempted to accept but everything was happening too quickly, I shook my head "Thanks, maybe next time."
I closed the bathroom door and stepped over to the toilet, raising the seat. I put some lotion in my hand and went to work. It felt strange touching myself with my parents just outside, knowing exactly what was going on, but I soon forgot about them and closed my eyes enjoying the sensations. Images of my mother's naked body flew through my mind and I imagined what it would feel like to have her touching me, would she use her hand or maybe even her mouth? My cock swelled and I moaned as my orgasm hit and I splattered a huge amount of ejaculate into the toilet bowl. I wiped down the errant drops that had hit the lid and seat and then flushed the evidence away. I washed my hands and used a towel to give myself a quick wipe between the legs before returning to the balcony.
I felt embarrassed as I joined my parents but, apart from a quick glance at my now flaccid penis, there was no other reaction. I soon relaxed and began to enjoy myself. We talked about the resort facilities and they told me about what they'd seen so far. Amazingly, I totally forgot the fact that we were all sitting outside naked. A chime sounded and dad said "That must be our food!
He stood up and went inside, returning a few minutes later followed by a slim but curvy young woman pushing a trolley. I panicked for a moment as I realised she would see me naked and made to cover myself. Mum anticipated my reaction and put her hand on my knee, shaking her head and whispering "It's OK Jack, don't cover yourself."
I forced myself to stay as I was and tried to relax. The girl introduced herself as Janet and smiled at us as she pushed a trolley between the sun loungers and then began to convert it into a table. I took the opportunity to study her more closely and realised she was very attractive. Her uniform consisted of a white, buttoned blouse and a rather short black skirt. Her ebony skin was smooth and glistened in the sunlight. As she bent over to retrieve a tray from within the trolley I caught a glimpse of the top of her untethered breasts. They were about the size of a small grapefruit and looked very appealing. If one more button of her shirt was undone I was sure I would have been able to see her nipples.
To my horror I felt the unstoppable onset of another erection as my penis rapidly inflated. I knew that lying on the lounger would make it unmissable so I quickly sat up, hoping it would not be noticed as it lengthened between my legs. Janet was still busy and thankfully didn't seem to be aware of my predicament. I observed as she crouched down to retrieve the lowest tray and was treated to a view up her short skirt. Her smooth, slim legs were parted slightly and I could make out the white lacy fabric of her knickers. My cock throbbed and I felt some pre-cum ooze from its tip.
As she stood holding the tray I saw her look at my crotch and smile slightly. I was sure she could see my boner and, although embarrassed, I was also excited by the fact that she was the second woman to see me this way. She continued working but I caught her glancing between my legs a few times and could also detect two obvious bumps in her shirt that I was sure hadn't been visible earlier. When she was done, she smiled and wished us an enjoyable meal before taking her leave. My eyes followed her as she walked away and I found the view of her curvy bottom encased in in the tight skirt enchanting.
My dirty thoughts of what she would look like naked were interrupted by mum saying "Um, that looks tasty!"
I spun around to find her looking at the plate of food and not Janet's bottom, despite this I was pretty sure her double entendre had been no accident. This was confirmed when she caught my eye and winked "Janet's a very pretty girl."
I blushed and nodded without replying. Dad joined us and we started eating. My burger was delicious and I wolfed it down in record time and then lay back to enjoy my drink. I'd totally forgotten about my erection until dad laughed and said "Wow, I must try the burger next time!"
I laughed and felt so comfortable with my exposure that I made my cock bob about by clenching my pelvic muscles. Mum almost chocked on her food as she laughed while eating and dad quickly handed her a glass of water. She drank rapidly and some of it dripped down her chin and onto her chest. I watched as the drops of water trickled down over the slight bump of her breast and then onto her nipple, tantalisingly hanging there for a moment before falling to her lap.
Dad had been watching the same thing and I held my breath as he leaned over and licked mum's nipple before sucking it into his mouth. Mum moaned and turned towards him, placing her hand on his head then breathlessly saying "Oh Philip!"
My penis throbbed and released some pre-cum as my parents got more and more intimate in my presence. After a few more sucks, dad pulled back drawing the breast out before he slowly let the engorged nub slip from between his lips. As her breast sprang back I was stunned to see her nipple was now bright red and almost twice the size of the other one. My mouth watered at the sight and I licked my lips wondering if I'd get the opportunity to do the same.
Mum's face and chest were flushed as she playfully punched dad's arm "You're terrible Philip! Now I'm all hot and bothered like Jack!"
