"Just a few more changes, I think," muttered Eros. "You need to be more focused on sex."
Derrick had to laugh. "More focused? With a cock like this?"
The handsome young god pulled Derrick into a warm hug and then slid his hands up and down Derrick's back. The boy gasped at the powerful sensations - his skin was like the head of his penis all over! Eros grinned. "First of all, you don't need to worry about eating or drinking. We'll make you totally self-sufficient."
Derrick did not understand at first, but then his gut started to churn. The sensation faded quickly, "You will never be hungry or thirsty again." Eros gave him a push, and Derrick toppled back into the pile of pillows. "Now then, instead of a third leg, how about some extra penises?" He grabbed Derrick's right leg and slid his hands from the thigh down to the toes, then repeated the action on the left leg. Derrick was puzzled at first, then his eyes widened as both legs started to swell out into rounded, familiar shapes. as his foot disappeared into a thick tube of flesh, Eros pulled the new foreskin back to reveal a cock identical to the one Derrick had in the middle. The pleasure and erotic sensations were more than he could stand, and three massive cocks erupted with thick semen. When he recovered enough to look, he discovered that his testicles had swollen to the size of basketballs, providing enough spunk to have all three dribbling.
Derrick felt tugging on his arms, and saw Eros grin again as he stepped back. "No!" The boy screamed but it was already too late - the transformation rocked his mind with orgasms, and when they had passed matching penises sprouted from his shoulders. "What are you doing to me?! Please, stop!" Derrick stared as the young god laughed. "You are not thinking clearly, boy! I am giving you the most incredible sexual experiences ever enjoyed by human or god. Think of it! When I am done, every touch, every movement will bring you the pleasure of orgasms! You will live in a pool of your own rich semen, exchanging pleasure with females, males, beasts, monsters!"
Eros leaned close to massage Derrick's torso. The boy expected yet another cock to push up from his belly. Instead, his body began to thicken and round out, shoulders dropping. More swelling and shifting came from underneath as more monster testicles formed. It wasn't until thick flesh began to form a tube around his neck that Derrick understood and tried to scream again. Instead of words, a gush of semen shot from the opening that had been his mouth. Vision blurred and went dark, but he could smell and feel and hear. Even if he could not see himself, he knew he was now a collection of six identical monster cocks, sitting on top of twelve monster testicles. There was no way he could be alive like this - he had no heart, no lungs, no brain. But he did not feel a need to breath, and he still existed. As a magical creature of Eros. Hands started stroking him, and various cocks began to swell. The pleasure was almost too much to bear, orgasms repeating over and over.
He heard Eros chuckling again. "You are mine for the next two weeks, boy. The world's greatest sex toy, 24 hours a day, seven days a week. I am going to move you to the Pleasure Pit, where guests and gods will enjoy your company non-stop. You do not have to worry about performing - I have changed your essence, your very nature. You think you are still a boy, but I give you only a day before you have no existence other than the one I have given you."
There was sudden lurching, and Derrick heard gasps and shouts from all around. Those faded into murmurs and then laughter as hands began to stroke him. He shuddered in orgasm over and over, each ejaculation met by shouts of appreciation. Eros had given him a full day, but Derrick was nothing more than a living sex toy after the first hour.
