Kara agrees to direct the couple

'They want you to be their, uh, dominator... dominatress? Whatever, they want me to control them, so if you're gonna do this, pull on your Supergirl pants... skirt... and be decisive even if unsure, heck, especially if unsure'
"I... Yes, I'll direct you and... stuff"
'Way to go Kara, that didn't sound clueless at all, gah!'

"So uh, what are the limits here? And what do I call you, just your names or, specific things or... you know?" Kara waves her hands around a bit before resolutely crossing them over her chest and trying to look calm and in control.

It's Bill that starts talking "Well, the safeword for the both of us is Sunflower, what we usually enjoy being called is anything from our names with **** in front of them to assorted demeaning names, sexually demeaning that is, nothing racially insensitive.
As for what you can do, most common sexual situations with the two of us, though nothing involving you, no offense, but we're just into each other.
Oh and while I'll suck a strap-on, I'm not into pegging, so that's a hard no, even if Amy were to beg you to let her do it, ouf, no hitting without her telling us!" that last comment is directed at his wife and said with a smile and a laugh.

'Wow, ok, that's a lot, though from what I saw through the other windows, it could've been worse'

"I guess I'll be mistress Da... hmm, no, Mistress El"
'Hah, Kal-El would so have a conniption if he heard, but really though, I grew up seeing people named El commanding others, so it fits better than Danvers... not that Alex can't be extremely bossy'

"That sounds good, oh, and some pain is fine as well, nothing that marks us enough to be visible tomorrow though.
Unlike the sexual side of it, any punishment we'd prefer you to administer, we really don't want to hurt each other... is this acceptable Mistress El?"

'Hmm, that feels kinda nice to hear actually... hmm, maybe I should pull out some of Cat's tricks, she was always extremely forceful and commanding... she had such a presence for a tiny woman, no wonder half the floor had a crush on her and half the floor were terrified of her... sometimes both'

"That is adequate Bob, now, don't lazy about on bed, get off it and stand up straight so I can look at you, you too Allie"
As the two jump of the bed, Kara stands up from the chair as well and strides over to the couple, looking them up and down and walking around them.
