"I guess I will go with your suggestion. Anti-aging and body sculpting."
The girl smiled and gestured to the opening on the far left. "Go through there. Adonis will help you."
Adonis? John felt a combination of disappointment that the attendant was not female and relief for the same reason. However, when he entered the indicated room, he stopped in his tracks and stared. A nude young man was kneeling next to a large square pool of what looked like steaming mud. The young man was gazing into a hand mirror, but put it down and stood when he saw John. Adonis was stunning - a slender athlete's build, movie-star handsome, and amazingly well endowed. His pale blonde hair hung to his shoulders, just tousled enough to look natural instead of styled, and his eyes were an amazing bright green. And then he smiled to reveal a dazzling display of perfect white teeth. "Welcome! I am Adonis." He spoke with a trace of accent.
John flushed, having to fight back a powerful attraction to this beautiful boy, feeling ashamed and embarrassed. "I, uh... maybe I should try something else." He stammered out the words and tried to avert his eyes, but, dammit, he kept staring.
Adonis laughed, a rich sound that sent a shiver up John's back. "Your reaction is normal. I am very attractive to males and females. It is part of my being perfect. You cannot help yourself." He stepped forward and took John's hands, pulling him toward the mud bath. "Come, and we will find your perfection." From anyone else the statements would have been pompous or boastful, but Adonis was simply stating the truth.
When they reached the edge of the sunken pool, Adonis helped John disrobe and looked him over. "Age has spoiled some of your attributes, but that can be easily remedied. And body sculpting will take care of the rest. Enter my mud bath and emerge a new man!"
Trying to joke, John said "How about a new boy instead?" Adonis did not even hesitate, nodding and smiling. "Of course! But not too young. You want to be able to pleasure yourself and others."
"Oh, right!" John smiled, figuring the kid was turning his joke back on him. "Lots of pleasure!"
Guided by Adonis, John stepped into the thick gray-brown mud, surprised both by the depth and the warmth. The sludge was hot, but not unbearably so. And it rose to his knees. He was grateful for that last, his somewhat flabby, hairy body looking even worse next to the incredible physique of Adonis. Sitting and then shifting to lay back, John's entire body sunk below the surface. He had to hold his head up, which he thought would get awkward in pretty short order. "Uh, do you have a pillow, or something else I can rest my head on?
In answer, he heard something plop in the water behind him. "Sit up for a moment." John lifted up, expecting a headrest, then stiffened as he felt Adonis slide down into the mud behind and then under him. Strong hands tugged him back, and he ended up with his head resting in the youth's lap, mud covering everything except his face and forehead. He looked up, flushed again both from the heat and the sensation of large male genitals under his head. Adonis smiled down at him and spoke, but the sound was blocked by the thick mud. For once, John was grateful that he was not as well endowed, for his erection was not quite showing above the surface. Maybe it was a 'normal' reaction, but this young man was barely older than his son!
Adonis used his hands to smear the thick mud over John's forehead and chin, then over his cheeks. It stayed hot, though he was getting used to the temperature. More mud was applied over his mouth, and then over his eyes. Soon, all that remained uncovered were openings for his nostrils. Any other time, John would have been tense about being so thoroughly buried, but he felt totally relaxed, even his embarrassment fading away. The heat penetrated deep into his body, and a few minutes later he drifted off into deep, dreamless sleep.
Adonis waiting to make sure the man was completely asleep, then slid slowly out from under him and used his hands to gently lower his head until it vanished below the surface. A single air bubble formed and then popped on the surface of the mud, and then it was still.
