Sara then put on a protective glove and a laboratory flask, and dipped the flask into the purple liquid to take a sample and analyze under the microscope. But when she took her hand with the vial from the substance puddle, the glove had been completely eroded by the substance, and what was addicted to her hand was quickly absorbed into her skin. Taken aback by this she gave a little scream and dropped the vial, crashing to the floor. Rich went to try to help her, but she told him to stay away.
"Even protective clothing is useless and I've been exposed. You better keep your distance until we know for sure what effects it can have on the human body." Sara said showing him what was left of the glove.
But, before Sara could do anything, her breasts began to grow. Sara's breasts grew so big that she had to take off her shirt and bra. By the end her breasts had gone from B-cup to H-cup. Soon after, a new pair of breasts grew below them until they were the same size as the ones above.
"Sara, you have to let me help." Rich said
"I told you not to get close. Just get me something to cover me and throw it at me." Sara said
Rich threw her the biggest coat they had, but she couldn't take it. He just watched as a second pair of arms grew on Sara below the originals.
Sara, torn between fear of what was happening to her and curiosity as a scientist, tried to examine her four breasts with her four hands. Then she began to feel pressure on her crotch. The increasing pressure was due to something that was growing and stretching her pants until the button didn't resist and burst, leaving an 11-inch hard cock exposed.
Rich realized that Sara was being overwhelmed with fear and, ignoring all her requests to keep her distance, he approached her and hugged her (she wasn't just his lab colleague, Sara was his girlfriend too.), calming her down.
Already calmer, she began to feel a lot of pain, stopped the hug with Rich and then remove her pants, which were hurting her new orange-sized balls. Then she paid more attention to the new hard cock and finally grabbed it for the first time. "I don't know why I'm so horny. This was not meant to happen." she said
Being understanding with girlfriend delw, Rich said "If you want I can help you, I can teach you some tricks." She returned hugging him again,wrapping him with her four arms and leaving her hard cock in the space between his legs, and they kissed.
Only when they thought Sara's mutation was over, she started to grow. She kept looking a little confused until she was already big enough for Rich's head to be level with her lower breasts, sitting on top of her dick. She set Rich down, and not knowing what to do, she tried to get away. Only she was so big that the only place she could pass was the exit of vehicles. Rich helped her open the gate.
By the time she left, Sara was already 30 feet tall and still growing. With her current size, there was no way she could hide and she was quickly spotted by people at the university.
When she reached 60 feet tall, she surrendered to lust and started masturbating right there. By the time Sara reached her final size, she was a 100-foot-tall giantess mutant dickgirl, jacking off two-handed on her 20-foot-long dick and the other two were turning to stimulate her four nipples.
Rich climbed to the top of the university building, yet he only reached her lower breasts, and then shouted for her attention. She noticed him calling, then picked him up and placed him over her head, where he gripped her hair tightly so as not to fall.
"Sara, pay attention to what you are doing." Rich said
"I know it's wrong to masturbate in public, but I can't hold back and there's no way I can go to a reserved place being so big. And we don't have much time either, I'm about to come anytime now." Sara said
"But not here. There are a lot of people around and you have Van-size balls. You could end up hurting someone." Rich said and looked around for a safe place where Sara could come, He saw the Olympic pool he had at the university and told Sara she could come there.
Sara agreed and ran as fast as she could to the pool, Taking care not to step on anyone and leaving a huge footprint everywhere she stepped. She made it in time, directed her dick to the pool just as she came. The first cumshots were so strong that they drove all the water out of the pool.
By the end of Sara's orgasm, all her purple cum had completely filled the pool.
Recovering orgasm, Sara watches the pool better, then she notices something. What did she notice?
