May lay very still knowing that she was seeing something which she wasn’t supposed to see. A low dimmed light showed at the other end of the darkened Winnebago where she could see her Aunt Sarah, her mother’s sister and Uncle Dan, her spouse, lying side by side on a double bed kissing on top of their bedcover with feet toward where May lay in a sofa bed with her two cousins, Jack and Sally. May saw that the adults were dressed for bed, just lying in
a tender embrace with their arms around each other as they kissed.
May could hardly believe that she was here as she hadn’t seen her cousins in several years, but two weeks ago her Aunt Sarah had called her mother to ask if May would like to go on vacation with them. Her mother had agreed to
the idea and they had stopped by in the middle of the night to pick her up at her house. They planned to drive through the night so that they could be at the camping park before morning. Her mother too, would go down in a few days to join them.
Her cousins, fifteen year old Jack and fourteen year old Sally, had been sacked out on the sofa bed in the middle of the travel vehicle when she got aboard. They’d woken up and the three of them had talked and giggled for a while before going back to sleep, having just dropped off in their clothes there on the sofa bed together. May was on the right side, towards the back of the vehicle, Sally was in the middle while Jack was snoring on the other side of Sally.
May had half-awoken when she’d felt the big Winnebago bumping over rough terrain then shortly after, she’d been vaguely aware of her aunt and uncle moving past her to where they slept to the back of the trailer and realized that they must have reached their destination. She’d just about dozed back off when she heard her aunt giggle and had peeked out to see what was going on to discover that they were smooching. Her aunt wore a short gown and her
uncle had pajamas on. Now as she watched she saw Dan stroking his hands all over Sarah’s big boobs before pulling a strap of her gown down to grasp her lovely bosom and to lower his face to the silky flesh. With his head in her
way she couldn’t be sure, but had the impression that he was kissing her on the tits. Dan slid down the bed a bit and as he moved his crotch came fully into May’s view, almost causing her to gasp aloud at what she glimpsed; his pajama pants were bulging! From the way they stuck out she knew that he had an “erection” as the books on sex called it, then watched him slip his hand up between Sarah’s legs, pulling her gown up as he did so. On reaching her crotch she opened her legs and May saw him slide his finger right up inside her pussy! She actually saw his finger disappear through the black hair and go inside her slit and watched her aunt reach down and slide her hand under the waist of Dan’s pajama pants where, from the way Sarah’s hand was moving backwards and forwards beneath the garment, knew that her aunt was stroking Dan’s penis as she held her breath.
After several minutes she saw her uncle raise himself to slide over on to her aunt as she pushed his pajamas down, almost gasped when his bottom came into view. She’d never seen a man’s butt and was very excited at getting to
view Dan’s, realizing that she’d become “sexually aroused”, as her books on sex-ed called it, with her virginal thirteen year old pussy wet with juice. She’d played with her pussy often enough to know what the feeling was.
Sarah pulled her legs up, her knees sticking up on each side of her Dan’s thighs and May knew that they were about to have sex, or to “fuck”, as some of her more experienced friends at school called it.
May watched her uncle’s bottom tighten as he pushed his hips against her aunt and realized that he must have just put his penis into her vagina. She almost giggled out loud as she thought in the terms which she’d seen in the books as her friend Jill, would have said that he’d just stuck his prick in her pussy. His buttocks tightened and relaxed when he thrust into his wife and then withdrew as May lay very still and observed his bottom, at the way the muscles flexed rhythmically as he rammed at her lower body with his own. Their lovemaking became more fervid and at an ever increasing cadence while aunt sort of moaned and groaned and grunted in time with Dan’s hard thrusts, sounding as if she was really enjoying the pounding she was getting.
Sarah’s hands slid down over Dan’s back to hold his buttocks, pulling and pushing as she encouraged him in his thrusting until May saw her legs jerk upward and heard her begin to moan and cry. He shoved forward hard and held her tightly against himself in the involuntary embrace of orgasm while his buttocks were clenched tightly and she could hear him gasping and groaning. She realized that they must be “climaxing” and his prick would be squirting his stuff deep inside of her.
After a few moments they lay still, May hoping that her uncle might arise so that she could glimpse his prick when he pulled it out of her pussy, but they just lay there until she’d drifted off to sleep before they moved.

May was awakened by a hand shaking her shoulder.
“Come on, May, rise and shine,” she heard Sarah’s voice calling her.
Sleepily she rolled on to her back. She’d been having the most wonderful dream watching her uncle’s bare butt thrusting and pushing, but it had been she that he’d been thrusting and pushing into!
Looking around her, she saw Sally sitting up beside her rubbing her eyes and Jack sitting on the side of the sofa bed beyond her as Sarah laughed at them.
“You guys got a lot more sleep than we did last night and we’re having to wake you up,” she laughed. “Come on now, I’ve got breakfast ready.”
She motioned them towards the front of the vehicle where May saw that the booth-like table was set with bacon and eggs and Dan was busy putting forks on the table. They didn’t need any more encouragement as they scrambled off the bed and headed for the table.
After breakfast they all went out together to look around the camper park. They were parked in a wooded area near a river and there was only one other vehicle in that part of the park, a big conversion van parked several sites away. There was a small, timber building near to the other camper which May guessed to be some sort of bath house. Their campsite was all the way down at the end of the row, with a picnic table and a campfire circle.
They walked down the road past the conversion van and on rounding a curve in the drive discovered a swimming pool ahead. Beyond the that there were a lot more campsites and what looked like a lodge. They walked on down to the pool to discover a concession shop beside it and while the kids went around to inspect the pool, Dan and Sarah walked on down to the lodge.
“Hey, look over there,” Jack whispered to the girls.
He looked back up the road in the direction of their campsite where they saw another teenager strolling down the road, a cute blonde a little on the chubby side, but what had attracted Jack’s eye was her figure, particularly
the big, bouncy boobs which were threatening to fall out of a skimpy halter top she wore and her shorts were so tight that they looked as if she’d been poured into them.
“His hormones are acting up,” Sally giggled to May as the girl approached.
“Hi,” she said as she came up to them.
She looked to be about fifteen years old and was quite pretty in spite of being just a little hefty. May and Sally quickly realized that her greeting was really directed at Jack, but they all responded and found that she was from the conversion van which they passed on the way down and that she was there with her parents, who were still asleep. Her name, she told them, was Bunny and she had been hoping that someone else her age would show up soon.
Again, she seemed much more interested in Jack than the girls as she spoke. They talked to Bunny until Dan and Sarah came out of the lodge to call them.
“Bunny’s hormones are acting up, too,” Sally giggled as they trotted over to where the adults were waiting.
“The bathhouse is available for us to use,” Sarah told them, “so we won’t be stuck with the tiny shower in the bus. Besides the van we passed, we’re the only ones on our side of the swimming pool right now.”
They explored the area some more before all heading back for the campsite except Jack, who was over by the pool talking to Bunny again.
Dan and Sarah were walking several yards ahead, arm in arm.
“I wonder how they’ll manage being in that trailer with us for the whole week,” Sally giggled to May.
“What do you mean?” May asked.
“Well, they like to screw a lot,” Sally explained. “Jack and I hear them going at it almost every night. I wonder how they are going to manage with us in the same room with them.”
May giggled and whispered to Sally what she had seen the night before and her cousin got very excited, wanting to know all the details, apparently a bit disappointed when May confessed that she hadn’t seen Dan’s prick.
“You should see it,” she whispered. “It’s huge! Much bigger than Jack’s!”
“You’ve seen them?” May asked.
“Sure,” Sally replied. “Well, I’ve never seen Dad’s hard, but it’s bigger soft than Jack’s is when he’s got a hardon.”
“You’ve seen Jack’s hard?” May asked with disbelief.
“Yeah and you probably will too, before this week is out,” she giggled. “And I’ll bet Bunny will see it too, if Jack has anything to say about it.”
When they came up to the bath house, Sally called out to her parents that they were going to stop there.
“I’ve gotta pee,” Sally told May.
May too was feeling the urge, so they entered in the females’ side of the bathhouse. Once inside they heard a shower running on the men’s side; Sally held her finger up to her lips indicating to May to be silent, causing her to wonder what her cousin was up to. She followed as Sally tiptoed silently into the shower room, apparently searching the plywood wall separating the men’s and women’s areas, then grinned and motioned to May to follow her as she moved right up to the wall and pointed at two small holes. She bent and peered through one as May bent to look through the other.
What she saw made her heart race; there was a naked man standing under the shower on the other side, right across the room from the wall with his back to them. May could see his butt, all hairy and hard looking and, while they watched, he turned around to face them directly! His enormous dick, hanging down between his legs, was then visible. The man who looked to be about the same age as Dan, was soaping his stomach, sliding a hand down to his crotch to soap his large hairy balls before his hand came up to encircle his large organ, sliding up and down along its full length, covering it with soap. As they watched his prick began to stiffen as his hand rubbed it, rising until it extended straight out from his hairy crotch. May couldn’t see as well as she would have liked because of the bubbly covering and his hand sliding up and down on it, however she could see the large purple knob come into view each time his hand slid down to the base of the huge shaft. Several minutes elapsed before he turned back towards the shower head and began to wash all the soap off of his body and when he turned around again, they saw that his dick had softened, pointing out and down, rather than standing up as it had been. He turned back toward the shower head again to let the water run over him a few more moments, then turned it off, moving from their view through
the door into the main dressing area.
Sally quickly left the showers to search the wall in the dressing room to spot some more peep holes, but they found that the man had finished drying himself off and was putting his clothes on, watching until he’d completely dressed and they saw him leave the bath house.
As soon as he’d gone May suddenly realized that she’d become desperate to pee while evidently Sally was feeling the same because both rushed into the stalls to do their business. When May had satisfied her need she met Sally
emerging from the next stall.
