Mistress Mona looked at Denise. "The beach is only a few minutes walk, so how about you change into your swimsuit?" The trio went into their rooms to change. Sonny boy had not packed any swimming trunks and waited on the couch.
Mistress Mona emerged. She wore a crimson red one-piece swimsuit. It accentuated her pert breasts and showed off her long legs. It was low at the back exposing an expanse of smooth skin. The attractive blonde teacher noticed Sonny boy had not changed. For his part he was looking at her lovely body. "Sonny boy, why didn't you change?" she inquired.
"Mistress I forgot to pack any swim trunks, so I'll just use these regular shorts instead" he replied.
The girl came outside. Denise wore a simple black bikini. Mistress Mona shook her head. "You can't swim in those darn shorts. That material is entirely too thick. When it gets wet, it will be much too heavy and cumbersome - you'd probably drown!" She smiled. "No problem though, you can swim in the nude!"
Sonny boy was aghast. "Mistress?" The pretty eighteen year old girl grinned broadly.
"Hurry up" Mistress Mona said.
Sonny boy shook his head. "Mistress I can't go outside naked!" She watched the boy, his eyes wide.
"Don't be silly. Lots of active boys go nude around here. This is summer vacation. Besides the particular bay area we are going to is quite deserted. We will be lucky to see anyone around. Nobody will see you."
He looked at Denise. "What about her?" She raised one eyebrow.
"Lady Denise? What's the problem? She's seen plenty of boys before!" Sonny boy looked at her pleadingly. Although she was only one year his senior, Denise absolutely towered over the lad. She played center and was the captain of the freshman girl's volleyball team.
"But Mistress, I'll be bare!" Mistress Mona tousled the dark hair of the naughty boy.
"If you had to be punished, Denise would see everything anyway, so you might wish to reconsider"
Sonny boy just stood there. Mistress Mona grew impatient. "I brought along a cane just in case it was needed, and I will punish you if you continue being so obstinate. Your behavior is just plain silly. You would think you had never been naked before!" Sonny boy knew he had to comply. She would certainly whip him severely if he defied her. This was just awful. He had to go outside completely nude! All the people they met would see him bare! He took off his shirt then eased his shorts and underwear down and stepped out of them. He stood there completely bare, his hands covering his little dick.
Denise was quite amused at his predicament. He was quite a handsome boy and looked even better in the buff she thought. She admired his dark tanned legs and midsection, and his starkly contrasting bare white butt, with cheeks so firm and round. Four faint stripes decorated the boy's rear.
They left the house, Sonny boy still trying to cover up his front. Mistress Mona smacked him on the behind. "Don't be silly. You can't walk around holding your little dick." He reluctantly dropped his hands to his side. Denise now had an unimpeded view of his privates. His thick boy meat was erect. He was acutely aware of how his boy balls swung side to side as he walked.
They soon reached the beach. The females laid out some towels and they sat down. He lie on his front, shielding his boyhood from their gaze. They could still admire his firm boy butt. The teenage girl began to rub sunscreen on her exposed limbs. Mistress Mona also applied the lotion. "Mistress", Denise interrupted, "What about Sonny boy?" Mistress Mona took the bottle and turned to the boy.
"Sonny, come here please, we really can't risk having you get sun burnt." Sonny boy reluctantly stood by her side as she covered his back and chest with the lotion then his arms. She poured out some more from the bottle and rubbed his legs. She turned him in various directions as she applied the lotion, holding onto his boyish pestle as she began to rub the sunscreen onto his butt.
Denise simply giggled. She smiled at them. "Boys come with their own little handle for turning them about - very convenient!" She finished by applying the lotion to his smooth hairless scrotum, rolling the testicles in her fingers. Sonny boy stood there staring straight ahead, embarrassed as hell, his face turning scarlet. Denise had eyes wide as saucers. She could see the faded marks left by the cane. "Mistress, has he gotten the stick?" Mistress Mona nodded.
"Yes, last week I had to cane him for touching himself down there without permission!" Denise counted eight faded stripes. Yes, they were all there, four on each cheek. She wished she could have seen them being administered.
Mistress Mona looked at Sonny boy's butt. Her hand gripped the bottom flesh as she continued to address the young girl. "Growing boys aren't harmed being striped like this. As a matter of fact, they need very firm discipline in order to keep them in line!"
Denise contemplated the scene. "The cane must really hurt though, to leave marks like that?"
Mistress Mona smiled grimly. "I suppose it does, but unlike girls, naughty boys require such painful discipline. And marks do fade so there is no lasting damage!"
Denise gestured towards the boy's butt. "Mistress, were those on the bare?"
Mistress Mona smiled. "Yes they were. As a matter of principle, I always administer canings on the bare bottom. It makes the punishment hurt more and there is the additional embarrassment of the boys having to bare their bottoms. Seems like ol' Sonny boy here has gotten the stick on quite a few occasions now, have you not?"
As Sonny boy sat down Denise noticed his erection and tight scrotum, all smooth and hairless. Mistress Mona's ministrations with the lotion before the young lady had caused him to become quite stiff. He tried not to notice all of the feminine charms that were all around him, the swelling bottoms encased in tight fabric, the smooth wide hips and full behinds.
"Mistress his thing is sticking out", Denise pointed.
"Boys often get excited like that", Mistress Mona explained. "Once he gets accustomed to being bare around you it will eventually go down".
Mistress Mona and the girl lie back on the towels, soaking up the sun and watching the waves break. The seaside view was very peaceful and relaxing. Sonny boy lie on his stomach, relieved the topic of conversation had moved away from his bare butt and balls. His gaze fell on Denise's lower body, admiring her slender legs and pretty feet. His eyes moved up. He could clearly see the outline of her pretty pussy, the thin material of her bikini clung to her plump, sexy pussy lips just like a second skin.
His mouth was dry as he continued to leer at the pretty young girl. One of her knees was bent and he gazed at the hard muscular sun-tanned thighs. His little dick was still erect and now, trapped between his body and the towel, was quite uncomfortable. He shifted his hips, trying to relieve the pressure on his boy meat, but to no avail. This was teasing and denial on a sublime level. A touch of S&M.
He tried to imagine what her pussy must have looked like under the shiny black material of her swimsuit. He wished she too were nude. It was so unfair he thought, that the girl, who was only one year older, was completely decent while he had to walk around buck naked. Denise was able to see every inch of his bare body. He didn't even know her before today yet she had seen his brightly striped bare butt and his exposed boy meat and balls.
As Mistress Mona lie on her stomach, he had a good long view of her bare back and how her swimsuit clung lasciviously to her beautiful butt. The lower edge of her bottom cheeks were exposed as the material of her swimsuit rode up and he was treated to a delightful view of his teacher's lovely lower butt.
Mistress Mona got up. "Let's go in the water" They followed her in, enjoying themselves in the waves. Sonny boy felt his boyish pestle go flaccid in the cold water. This made his exposure a bit less humiliating. They didn't stay in for very long because the temperature was so cold and soon were back on the beach, toweling themselves dry.
Denise giggled, her finger pointing at Sonny boy's midsection. "Mistress, look how small it is now!"
Her pretty blond teacher smiled. "Yes, the water is very cold". Sonny boy looked down. His cock had really shrunken and his balls were drawn up against his body.
Denise looked down at the shivering boy's privates. "It's amazing how it changes size like that!"
Mistress Mona turned towards the boy. "Sonny, did you clean out the sand from underneath your balls?" He was dumb-struck. The girl just giggled. Before he could do anything Mistress Mona had grabbed him by the dick. Holding it in the fingers of one hand, she used the other to reach behind him and brush off any stray grains of sand there. Denise simnply watched in rapt fascination as Mistress Mona roughly handled the boy's cock. Finally she released it. They all sat back on the towels.
"Right then - Sonny" she said, dismissing him with a loud smack to the bottom. She opened a book and lie back, feeling the sun on her skin. The women sunbathed while Sonny boy went to the water's edge. He started to construct a very elaborate sand castle.
A half hour passed and Mistress Mona began to gather up the things. Sonny reluctantly left his creation. "Mistress, did you check what time the museum opens in the morning?" inquired Denise. The girl wanted to do some sight seeing after wards and they had decided to visit the naval history museum just as it opened.
