you dry-hump him

Gemma clearly needed some more stimulation, and so did you. You took off your pants and crawled on top of Gemma’s body. Once you were far enough, you sat down and dropped your pussy onto Gemma’s cock. He didn’t enter you, so you weren’t fucking. But you did slide your pussy up and down the length of Gemma’s cock.
“It’s fine.” You thought to yourself. “She’s only going to cum on her belly.”

Gemma enjoyed it too. He took hold of your breasts and groped them. You opened your mouth and gave a loud moan.
It felt so good you were almost happy to be in your female form again. For a moment you lost yourself into your lust.

When you got back to reality, you realized you and Gemma had switched positions. You were now lying on your back, legs spread, with Gemma in between them.
“It’s fine.” You thought to yourself. “She’s only going to cum on my belly.”

Gemma took great interest in your breasts and touched you unlike ever before. It’s probably because he used to be a girl himself and knows which buttons to push.
But then you felt Gemma’s cock go a bit lower. Once you felt his cock trying to poke it’s way between your lips you knew what he was planning. You wanted it too, but if you allowed him to cum inside of you, you could get pregnant. And if that happened, not only would you stay forever in your female form, but Gemma too would stay in his male form for the rest of his life.
