Have Sabrina blow you while giving Katherine something to play with

“I’m going to tie you to the bedpost,” you tell Katherine, guiding her to the corner of your bed where she can be bound while on the floor. Once she is secured, and looking like a **** girl, you silently signal for Sabrina to kneel across from her.

Sabrina grudgingly complies, facing her twin and holding up her camera to record what happens.

You walk over to your closet where you stashed your mop from the earlier cleaning, then return to the bound girl.

“Now…Sabrina...” you say, addressing Katherine so that Sabrina doesn’t actually respond. “I want you to suck on this…”

You hold the plastic stick end up to her lips. She pulls back when she feels it touch her, then opens her lips to sample what it is. “What? This isn’t your dick!” she realizes.

“No, I’ve decided you’ll have to earn the honor of sucking my dick. I want to know that you really want it by showing me how you do it with a proxy.”

“Wait… Is this a dildo?” She asks you, tilting her head in confusion. “What are you doing with a dildo?”

“It’s a mop end, now suck it,” you tell her. “And tell me how much you wish it was my dick instead.”

“This is getting stupid,” Katherine belittles under her breath.

“Huh… strange. You were all into this stuff last night…” you tell her. She bites her lip and you know you have her again. “Then again, it was office supplies there… maybe we could take this into work and…”

“No no… I like this, really,” Katherine quickly says. She would rather not prolong this and risk getting caught at her sister’s place of work. She licks the mop end like it is a lollipop and gushes, “Oh, master, your stick is so… um… long… and hard!”

“Keep at it, get it nice and wet,” you tell her. “You’re going to want it fully lubricated for where it’s going next…”

Katherine swallows the lump in her throat, understanding your intentions. She continues to lick, thoroughly coating the cleaning equipment with her saliva. As she does this, you signal for Sabrina to start sucking on you as well. Sabrina has her camera aimed at her sister and she tries to keep it steady as she kneels down and guides your cock into her mouth.

You suppress a moan as Sabrina slides you in like a cigar, smoking it with her eyes directed at her sister. The fact that she went down on you without hesitation tells you that she is so intent on getting footage of Katherine that she would do anything it takes to not interrupt.

You thrust your hips into Sabrina’s mouth and let out a groan. Sabrina freezes, thinking her sister might suspect something, but you groan at Katherine, “Ahh… yeah, pretend that’s my cock, work your tongue around…”

Katherine follows the instruction, graphically swirling her tongue around the tip of the mop handle. She knows how to play it up for the viewer and is sensually oralling the inanimate object. While watching, Sabrina can’t help but mirror her twin’s actions on your actual cock, making the twin visual even more arousing. They both go at it in unison like they are of one mind and it quickly drives you closer to the edge.

You can’t keep on much longer but you doubt this is enough for Sabrina’s video.

“OK, enough of that,” you tell both of them. Katherine pulls off of the mop handle while Sabrina keeps going on your dick. You sigh softly and pull Sabrina’s soft, pouty lips off your cock. You inspect the mop end and compare it to your cock. They both are coated with a wet, glistening sheen from the two girl’s mouths.
