Suddenly his dick ruptured forwards. He groaned as cum flew out of it. He fell back into the sauna completely submerged in the magical liquid. He could feel his muscles grow even more, pumping outwards like balloons.
Alex quickly realized his mistake and attempted to get out, however this came to no fruition because as he emerged from the water his dick pulsated again causing him to grown with pleasure. He thrusted himself inside of the sauna, seeing his dick grow even more in size. He grabbed it trying to relief some of the change, however this only made it cum even more.
Alex reached with his giant long arms to the sides of the sauna, pushing himself out above the water. Alex was surprised with his strength so surprised he gasped out in pleasure "I'M SO STRONG!" he screamed loudly. He threw himself out the sauna and lay on the ground with his dick violently pulsing and his muscles still shaking and slightly growing. He grabbed his bicep and fondled it, amazing at how big it was. It was 2 times bigger than a melon and filled him with so much more pleasure.
He looked at the sauna and stood up flexing his entire body.
