No, so You Take Her Instead.

You looked at the Captain for a moment, you knew there was likely no way to explain what had happened that would satisfy her as she moved up close to you. You had to move quickly if you wanted to act, but you had a plan already, all you needed to do was wait for the right moment.

"Ma'am, I..." you started to say.

"We are waging war against demon invaders who can grab us and make us into one of them," the Captain said. "We are in no position to leave our posts without reason. Did you have a reason, Private?"

"Oh, I had a very good reason," you said, no longer pretending. "And I'm going to show you."

You lunged forward and grabbed her, kissing her on the mouth and forcing your tongue in. The Captain struggled against your grip as your body took on its liquid form again, feeling some of it entering her mouth. She involuntarily swallowed as her body was infected by you.

You pulled back, covering her mouth with your hand as her eyes rolled back and she moaned.

"What... what are you doing to me..." she moaned as her skin started to take on a liquid quantity as if she was melting as you burned her clothes off. "No..."

"Join me, sister," you said as you stretched your other arm out and used it to secure the entrance. "There's no escape for you."

You **** her down onto the ground as you straddled her waist, your liquid body merging with hers. She was melting into you and you could feel the pleasure running through her body as you grinded against her. Instinctively you knew that once she came, she would become like you. The two of you moaned in mutual pleasure as your bodies merged together into a blob of sexual pleasure.

It was like your whole body was on the verge of orgasm, and you knew she was the same. You thrust yourself into her and your body rippled as you both came at the same time.

You disconnected yourself from your sister as a liquid demon now laid before you, fingering her pussy. Her breasts had grown out and her body was as perfect as yours. You could still sense and feel what she could though, you were connected to her in ways you couldn't have dreamed.

"Thank you sister," your new sister, Julia said as she enjoyed her new self. "We are one... now we must bring more into the oneness."

You both moaned as you came at the same time. The connection between the two of you was so powerful, and you loved it.
