Use a psychic strap-on

"How's my favorite servant doing tonight...❤?" Emma entered the room with a smirk that immediately put Danvers on edge.

"What ever you had planned, just drop it. I don't want to play any more of your damned games!" She stared daggers at the other woman as she watched her set a camera on the table. That was the last thing she wanted to see.

"Oh, I bet you don't really mean that. Or, I should say, you won't mean it soon.... I'll admit, this next game is going to be embarrassing for you, but I also think you've always wanted to call me queen..."

"You don't own me, Emma! You need to understand that right now!" Carol's hands started to glow, but suddenly an invisible force was used to hold them in place.

"If you need something to do with your hands, you can bend over and spread those perfectly shaped cheeks of yours. Go ahead and leave the suit on though, I think this will make a much stronger impression if I show you I can fuck you whenever I want, even when you're still dressed." She made a twirling motion with her hand, and Danvers faced the other way, leaned forward, and grabbed her own butt.

"Oh no no no no.... w-why am I facing the camera...?", she stammered.

Emma put her hands on the other girls hips. "MMmmmm..... feel that shaft going into you? You need to tell everyone how it feels, because they can't see it. It's the only way they'll know the great Captain Marvel is powerless when I fuck her from behind...!"

"Uhh...! Nnghhh...! I-It's so good...! Nghh! I...I can't fight it... Oh God...!" She bent over a little farther now as she stared into the camera, her eyes begining to glaze over. "I didn't think I had a weakness, but the way she fucks me makes me feel powerless...! I'd do anything for more...!"

"More?", Emma giggled, " I can do that. " She let go of the other girls hips and pushed her own hips out. "Now push yourself back onto it the way a little slut should!"

Carol's eyes widened and she began panting as she started slamming her butt into the other girl's crotch. "UHH! UHHH!! I can feel another one...! There are two inside me....! AHH!! Uhh...! I am a slut...! Feeling it in my ass, too... I - I can't stop myself!! Uhh! UNHH!!"

"No, you can't. I can start fucking you through your special little suit whenever I want. Where ever you are. And once I start, I can make you ride it yourself. I can make you beg me to butt fuck you, to moan like a whore...! You are mine, and I want everyone to know...!"
