Unexpected effects.

Bruce felt as, with each pull, his cock grew and grew. "Ooohhhhh.....," he moaned in pleasure as his incredible erection showed proudly between his chiseled groins.

Clara watched with scientific interest the growing manhood of her muscular test subject, a noticeable thick 10-inch virile member. Nothing interesting at the moment. Another very well endowed man...moaning with pleasure on that massage bench. That wasn't exactly what I was aiming for with that injection.

"Maybe he needs some more stimulation....".-Clara thought as she grabbed Bruce's virile member and began stroking him again. Slowly, all along its lenght.

"Aaaahhhh.....".-Bruce howled in pleasure, as he felt the climax getting closer and closer. His muscular and defined naked body twisted and twitched on the massage bench.

Clara arched an eyebrow in surprise. She felt Bruce's cock seem to grow bigger and bigger, thicker and thicker. It seemed to be about 12 inches long now. And it was thicker than before. It was jerking out of control with ****. Sprouts of cum shot out of his aroused manhood like shotgun blasts.

Mind-blown, Clara watched as his scrotum grew as well. She could see his bollocks clearly, pulsing slightly, growing. This was not what she expected. It was surprising...and interesting.

Clara increased the pace of his handjob. Bruce heaved and panted out of control, writhing in pleasure on the massage bench. His cock spilling cum hard on the massage bench. But, despite this, he doesn't climax. His manhood was now 13 inches long.

Bruce moaned and squealed with pleasure on the very brink of orgasm, but without reaching it, as he screamed in pain from the aching erection throbbing hard between his legs.

"Interesting...."-Clara smiled, as she released Bruce's cock, and texted her attendant.

The attendant smiled as she received the message from her boss. She knew what to do next.

"Relax, Miss.", she said to Rachel as she walked over to a cabinet and pulled an unlabeled jar out of it. "Please turn around." She added in her silky voice.

Rachel obeyed, than giving her face up, naked on the massage bench. "I think I should..." she began to say, as the attendant poured a stream of oily liquid over her torso.

"Relax. You'll love this..." The attendant whispered to her as she placed her hands on her and began to smear that smelly liquid all over her torso, caressing her shoulders, her neck, her abdomen...and especially her breasts and her crotch

"Eh?! How dare you....?"-Rachel started to protest, when a warm and cozy feeling began to invade her body. A moan of pleasure escaped her lips as a blissful expression appeared on her face.

"Just relax. Close your eyes, and enjoy....".-The attendant whispered to her, as she poured more of that oily liquid over her. And smeared it all over her. Especially on her small but firm tits.

Rachel was writhing with pleasure, moaning, on the massage bench while the attendant, also aroused by Rachel’s screeches of bliss, kept caressing Rachel's torso, feeling her nipples harden and harden under her massage.

And then, after a few minutes, the attendant felt it. And she saw it. Rachel's tits seemed to be growing. Firm, rounded. By the second, they were getting bigger and bigger. A few minutes ago, her hands could cover her breasts. Now, her breasts could cover her hands. What a few minutes ago were tits, were becoming in large knockers.
