Mike

Without hesitation I tapped on Mike's face. Shock spread across Carla's face as my body swelled and darkened into that of my best friend.

Her shock quickly turned into sort of a giggle and I realized too late that I was still dressed in my Susan outfit, so Mike was dressed in a plaid skirt, blouse and blonde wig. The buttons on the blouse were stretched to their limits, and the bottom stopped somewhere around his belly button. The elastic waistband of my skirt was stretched to the max and I was pretty sure the fabric of my panties actually ripped while trying to contain his big cock.

I could understand the giggle. I had to look absolutely ridiculous.

After her giggle subsided, the shock on her face turned to a look of sadness.

"So he wasn't real?" she asked.

"I'm afraid not," I told her. "The real Mike is hours away living his life. My wife is the one who used this body to impregnate you."

Tears began to well up in her eyes, so instinctively I wrapped my arms around her and pulled her into what was meant to be a comforting hug. I wasn't prepared to sandwich my cock, still hard after the transition, between us.

Carla looked up at me for a moment, then wiped her tears away.

"At least let me say goodbye," she said.

When I said nothing, she gently pushed me back to the couch, where I dropped onto the seat. She flipped my skirt up, then reached down to slip Mike's big cock out of my panties. Instead they ripped open and it spring free on its own.

Carla straddled me and slid the big black cock into her, orgasming almost at once.

"Oh, fuck," she moaned. "I'm going to miss that. I can't believe it's not real."

"It's as real as you want it to be right now," I said.

She kissed me as she began slowly riding Mike's big black cock. Carla's pussy was hot and wet and fit tightly around the big shaft. I could feel her cumming so intensely. I gripped her ass and pulled her hard down against me, causing her to squeal in pleasure.

There was nothing more to be said after that. I just kissed her back as she rode me, my hands gripping her firm young ass. Otherwise I just let her take her time, which took much longer in Mike's body than it would have on mine. I would have already cum long before then.

I have no idea how long it actually took, but my the time I filled her already impregnated womb with Mike's seed, we were both sweaty and out of breath. She kept kissing me for several minutes afterwards as my cock went limp inside of her.

Finally she climbed off of me and sat down on the couch, the look of sadness returning to her face.

"He really doesn't exist?" she said softly. "She just used me and knocked me up without any concern at all?"
