More and more hair began to cover Marina’s body, to the point where she had to strip out of all her clothes just to keep from messing up her clothes. She grabbed her chair while she felt her first erection. She watched as her shaft began to enlarge. She felt like stroking it, so she laid on the floor and placed her hands on it. As she stroked it, it started to change shape, like it was doubling in length. After a few second of stroking and growing, she held her cock as it pulsed and jizzed everywhere. Her balls never got smaller as she coated the office in hot, sticky, horse cum. She stood there in a daze for about two minutes as her cock continued to pump out more jizz, and then it finally stopped. Marina finally snapped out of it long enough to assess the damage. Her office was covered in jizz, the carpet has puddles everywhere. Her clothes were now ruined, not like she could fit in them anymore. She had gain about a foot of height, her breast got larger, and she had cock that would put any man to shame. She looked and smelled like a horse anthro, and she was not gonna hide that no matter what she did. So she did what any sensible person would do in this scenario...
