The implication (Shapeshift Caption)

As Darryl opened the door to his house, he could have sworn he had heard an unusual noise coming from somewhere in the house. This threw him off, it was just him and Mark living here; both of them always let the other know when company would be swinging by. Moreover, Mark was usually in class at this time, so unless he was skiving off, there weren't any other reasons for these sounds. As he dropped off his backpack on the way to his bedroom, he was ready to dismiss things as pure imagination. However, as he walked out into the hallway, he definitely heard some giggling coming from the other side of the house, which piqued his curiosity. Walking over, he gradually found the source, which was Mark's room; of course it was locked, but damn, whatever was behind it wasn't quiet. Darryl planned on busting in to make a dramatic entrance, but given how mysterious this was, subtlety was a better route. As he opened the door, he stopped in awe and even had to pinch himself.

There was a blonde girl vigorously playing with herself, seemingly without caring how loud she was.

"WHOA! Who are you and what are you doing here?!"

She looked up and giggled seductively.

"Teehee, oh me? Mark brought me over but he left me all by my liddle widdle wonesome. Waiting for him is no fun, and I was too horny to wait for him to come back," she giggled again, "Like what you see? You look like you could...keep me entertained."

He was turning red in the collar by now. Why didn't this feel right?

"Um well, I didn't expect to find you here and honestly, it's...a bit weird."

Flashing that flirtatious smile of hers, she continued to undress him with her eyes.

"Why don't we take advantage of this situation then, darrrrrrrrling? I want you, and I want you right now!" she purred.

Little did he know that Mark was a shapeshifter, and he was about to find that out the hard way.

"Wow, I didn't know you could do do that!"

As they were lying naked, post-coitus, Darryl was reeling from his wild time with Sarah. She smiled at him in a catlike manner while he panted like a dog; the latter couldn't believe that he had almost turned down the opportunity.

"Babe, I can do lots of things," she laughed in a flirtatious manner.

He looked into her eyes with an impish smile, then laughed

"Oh yeah, like what?"

"I can te--actually, I want to show you!"

He thought he could handle what was coming next, but his smile turned to a look of shock and horror.

Her wonderful body enlarged in a bright flash, and his housemate's body appeared in her stead.

"M...M...Mark?! What the hell, man?!"

"Ha, got you! Did you really think a girl like 'Sarah' would be here all alone in my room? Damn man, guess you can't pass up that pussy! Not that I blame you--it was amazing being in a body like hers!"

As Daryl sputtered out an obscenity, Mark gleefully cherished his current situation and how wonderfully endearing his housemate was.

"Hey, if it's any consolation, you were dynamite. Out of all the times I've morphed into a girl, I'd never experienced anything like you!"

Resigned himself to the embarrassing fact that he had been duped, Daryl stared at the wall. He felt...blank; a defense mechanism to prevent his own foolishness from sinking in. It was a rotten feeling when you realized you'd accidentally fucked your roommate, which was a sentence he never realized he'd formulate.

"Hey man, I know how you're feeling," Mark finally spoke up. "I didn't mean to make you feel that way."

After some time, Darryl finally spoke up.

I don't...I mean...this feeling is....." He managed to concoct a few sentences from his blunder. "Sarah... she was too real, but this is weird knowing you and I banged. Things feel awkward now, and I don't know what this means for the two of us."

There was a small pause.

"Look, I get it. I should've told you that I can shapeshift, and now that you know, I feel bad. Really bad. Is there anything I can do to make it up to you?"

"You know what, I'm not gonna be the idiot who passes up this opportunity. If you can shapeshift to your heart's content, I'm sure this is gonna be a wild time. Things are already weird, so fuck it, no turning back now. Now, there's this girl I wish I could meet..."

"Say no more dude, I gotchu!"
