Chris gawked at her chest when they were trapped in a shirt. Having been released, her boobs had grown a noticeable amount because of the serum. The first time he saw her topless, his shorts went from baggy, to tightly stretched across his gigantic member which seemed to have swelled to eight inches long very quickly. He quickly tried to cover up, but she had seen enough to have an effect on her. Despite being covered by his shorts, the veins and ridges of Chris's cock were clearly visible; much so that Jennifer could feel herself heating up and getting wet between her legs.
The idea that her budding son could find pleasure in her thirty-year-old body left her in disbelief. Normally, Jennifer hated this kind of staring when it happened to her at work when her co-workers her age treated her nipples like her eyes, but the fact that a younger man found her sexy made her feel desirable and confident - even if that young man happened to be her son.
Being topless, her breasts jiggled without restraint with the slightest of movements. As they ate, she could tell that her son was having a difficult time keeping his eyes off of her tits and she repeatedly saw him trying to nonchalantly readjust his seemingly-perpetual erection under the tablecloth.
Her breasts were also dripping profusely. At one point, as Jennifer reached across the table for something, several large drops of her milk fell into Chris's cup of coffee. She didn't say anything, and he still drank the cup. Either he didn't know, or he pretended not to notice taking a sip shortly after. Either way, Jennifer couldn't help but get slightly aroused at the fact that her son just enjoyed some of her breast milk coffee.
The warmth and dampness between her legs intensified.
When asked about his own progress with the serum, Chris said that, like herself, he said that he was "definitely growing down there, and I'm producing a lot more ... you know ..."
"Cum?" she chimed in, slightly surprised at her own use of the dirty, sexual slur. This serum seemed to not only change the way her body looked, but also seemed to affect the way she talked and acted. She'd have to be more careful next time.
He initially looked taken aback at the word before smiling. "Yeah, I'm producing
so
much more cum lately. But it's also taking me so much more time to cum than before," Chris said as he adjusted his cock once again, suddenly interested in his food again.
Sensing his growing discomfort that was largely caused by her large breasts, a devious idea form in Jennifer's mind that they could both benefit from. "I was on a call with Meiko earlier today and he said that wearing clothes over the experimented area can restrict the production of fluids- for me that's my milk and for you," don't say it, don't say it, don't say it, "your cum." Now it was her turn to smile.
Chris's head shot forward, his eyes wide as he shifted in his seat, sputtering to find words.
A war was going on in her head - one side, her motherly side, begging her to take control of the risky conversation that she was responsible for starting, the other side, her horny, re-emerging teenager, serum-induced side, coaxing her to get Chris to cum onto her inflating tits right then.
Her horny side was winning.
Finally rediscovering his voice, Chris responded, "Do you mean-"
"Yes," she said, cutting him off. "I'm suggesting that you stop restricting your dick's growth so that I can see how big it's become-" she caught herself, blushing, a small, warm puddle forming between her legs, "for scientific purposes, of course," I winked. My motherly side was screaming right now while the serum ignored it completely, tilting my chin up and biting my lip seductively.
