She got aroused

"Oh my god! You have turned me into a Milf." Joan said in her voice matching a young woman. It felt out of place coming out of the mouth of a mature woman. But that didn't bother her. She kept looking down to her hands squeezing her big bust. She let out a high pitched moan as her fingers touched her hard nipples. They were bigger and more sensitive than before. Even through the dress they felt like small hard penises. Joan had nearly forgotten what it felt like to touch her own erect penis. It was something she normally didn't care about anymore. But with the sensitivity of her big round breasts under them, she loved the feeling.

As Joan kept playing with her breasts and nipples, accentuated by her moans, she began to feel a pressure between her legs. It got stronger and stronger the more she played with her breasts before she felt something between her legs shift inside of something silky. It felt like something Joan knew, but at the same time didn't. Joan felt more and more aroused, but not just from her tits, but also from the unfamiliar feeling between her legs. As her view rose from her cleavage back to the mirrors reflection, she pulled her hair from her right side over to her left side, letting it beautifully fall over her left shoulder. She looked at her dresses hem in the reflection and saw a vertical line despite the tight fit. Again she squeezed her breasts with both hands. A pleasant shock ran through her body, like normally when she was aroused. It made Joan moan, but also seemed to cause a twitching on the dresses hem. The vertical line was now more prominent. Joan kept her eyes on the twitching line as she made herself feel more and more aroused. It started to look more like a tent-like shape formed on the dresses hem, and it got bigger and bigger.

Then Joan felt a pleasant shock as she felt a something hard, jet soft and warm move between her legs. At one go it got pulled out, only leaving an afterimage of the feeling. But what Joan saw was shocking for her. The tent on the dress had suddenly gotten bigger, and something long and thick and skin-colored stuck out of the dress. Joan stopped playing with her breasts, but it didn't stop the thing under the dress stop twitching. Not wanting to believe her eyes, Joan moved her hands down to the dresses hem and lightly lifted it. A shocked expression formed on Joan's mature face as she saw what caused the dress to tent up.

What Joan saw growing out of the fuchsia thong she wore was a cock. A real gig, fat cock that had just squeezed itself out of its tight prison and was now starting to stand up. And despite it still wasn't fully erect, it was already bigger and thicker than the cock Joan had weeks ago, when she was still calling herself John and she thought of herself as a normal boy with just the problem of premature ejaculation.
