When Martha arrived in the testing room, she saw that along with the team that would observe the experiment was Gloria. Her friend said she asked the scientists to let her watch along and they imposed two conditions. The first, which was that she shouldn't tell anyone what she saw there, she had already agreed, and the second was that Martha herself would give authorization.
Martha knew this decision was one she wouldn't have made before, but she was feeling so comfortable around Gloria that she said "Of course she can watch, she can even apply the lotion herself if she wants to." Immediately she thought that she had exceeded the acceptable limit, but Gloria liked the idea and offered to do it while one of the scientists said that it would not be a problem since the result should not change regardless of who applied it.
Everyone went to their seats. Gloria, having undressed as well to avoid any unwanted dirt on her clothes, put the lotion on her hands, applied it to her friend's hard cock and kept stroking it. It didn't take long for Martha to feel that feeling again and marvel her friend as her cock got bigger, soon it had reached 11 inches, then 12, and when it reached 13 inches she came. This orgasm was different from the ones she had in the previous test sessions, because this time the cum ended before the orgasm, so that in the end she was still coming but nothing came out, her balls apparently hadn't changed at all, even her sensing something was going on there, and, after the orgasm, her cock stayed rock hard.
Gloria then made Martha lie down, pressing the woman's cock against her belly and sitting on her, moving her hips and rubbing her pussy all the way down the shaft of her friend's cock, which was still shiny with the mix of precum and lotion.
Martha let Gloria continue for a second round, little realizing that her cock grew even larger reaching 14 inches, her sack sure seemed to be getting fuller than before. When her cock reached 15 inches she came again, this time a full orgasm with more than ever amount of cum flying from the tip of her cock, this time lasting until the end of her orgasm. Even as she came Gloria didn't stop rubbing herself against her cock, seeming lost in her own thoughts, but her friend's pussy felt weird. It was only when her orgasm was ending that Gloria moaned louder and she saw something white fly over her, that she looked over and saw that the lotion had affected her friend too, who was now ejecting cum from a 4 inch cock she had just grown between her legs.
"Oh Gloria, look, now you have a dick too." Martha said
Gloria looked at her new cock, and the little ballsack at the base. She saw that she still had her pussy, and soon knew it was the same size as Martha's after the first test session. "I didn't think I would be affected as well, it seems the lotion can affect other people as well if there is contact before it is fully absorbed into the skin." she said
The two got up and, feeling the weight between her legs, Martha saw that her testicles were still the same size as before, but now she had three of them.
"This I did not expect, what do scientists think about it?" Martha said
They went to talk to the scientist responsible for observing them, and found her distracted at work, with one hand inside her pants making movements of someone who was clearly masturbating. They called Dr Alex, who was startled to realize that the two were there wanting to talk to her, took her hand out of her pants and apologized for the distraction, but made it clear that she saw very well when Gloria's dick grew and Martha's third testicle too.
Dr Alex called the entire team of scientists together to discuss what happened. They decided to get some materials for Martha's clinical exams, so they took samples of her blood, saliva, urine and even her cum.
For Gloria they gave her some options to choose what she would do: because she was already affected she would receive some money to pay for the misfortunes, and then they asked her if she would want to be part of the experiment too or would she leave it as it was until they could make her back to normal. She chose to be part of the experiment as well.
As they discussed the future the women put her clothes back on, Martha noticing that the tip of her cock, which was now 8 inches long soft, was visible under her skirt. The scientists asked if she wanted to stop or if she would continue with the tests, as they knew that she was a single mother of a young son and, judging by the size of her dick now and that there was still 6 sessions left, which if they followed as already carried out would probably make her life very difficult. She said she would think about it and would get back to you later with an answer.
When they left, Martha was surprised not to see Raven, but then she thought that he might have already left. Walking into the parking lot with Gloria and her car, they saw a parked car from which there was a sound of something being sucked and looked into it. They saw Raven sitting in the passenger seat accompanied by a petite woman who was in the driver's seat. His breasts were now G-cups and the girl in the car was sucking one of them.
Raven noticed them staring and signaled the girl to stop sucking on his nipple and look out the car window. She saw Martha and rolled down the driver's side car window, then said "Hello, so you are Martha."
"It's me, and you must be his girlfriend June if I'm not mistaken." Martha said
"Exactly. It's a pleasure to finally be able to meet you, Raven spoke a lot about you and how you ended up getting into the mess of the lotions exchanged for the experiments. He must have already said it, but I reinforce that if you need personalized clothes, just say so." June said, and looking down she noticed the tip of Martha's dick exposed under her skirt "And by the looks of it, you already need it. If flaccid is already big like that, imagine when it gets hard. No way are you going to find clothes to buy that are big enough."
"Thank you, just let me know when you have free time to take my measurements." Martha said
"If you want, you can accompany us to my apartment. I'm off today but I didn't bring any sewing or measuring tools with me, there I can prepare something emergency for you while the others are not ready. You don't want to walk around with your dick exposed do you?" June said and Martha agreed
"I noticed that you and your boyfriend were having a great time together." Gloria said butting in on the conversation
"It's just that with today's test session my breasts started to produce milk and she insisted on drinking directly from me." Raven said
"And I know you were enjoying breastfeeding me since you didn't even try to stop me. And for your information, your milk is very tasty." June said
"Whatever. But who are you? I believe you're a friend of Martha's, aren't you?" My name is Gloria. Martha and I were friends in high school, but we hadn't seen each other in years. We ran into each other at the mall a few days ago and ended up getting closer.
"Perhaps we got closer than we expected, you and ended up being involved in the experiment." Martha said
"What do you mean, was involved in the experiment?" Raven asked
"No big deal, except now I have a dick too." Gloria said
"Nice. Get in the car and let's go to my apartment then." June said
"No need, we have my car. You can go ahead and we'll follow you." Gloria said and with a wave she and Martha went to her car.
