Cuck Katherine with her sister

Your cock grows in Sabrina’s mouth, causing your eyes to widen at the sensation. She is barely able to keep you in her without gurgling or sputtering for air. She glances at her sister, eyes still closed and unaware of her presence. You lean back against the door frame and let Sabrina bob her head back and forth on your stiffening cock. You want to let out a moan but also don’t want to tip off the naked girl kneeling on the bed.

It is an amazing feeling having your co-intern’s mouth around your dick while her sister waits patiently on your bed. Now that you have both of them playing along, you become emboldened to push the envelope further!

You pull out of Sabrina’s mouth and lean in to whisper, “grab the rope and blindfold from the kitchen.” She nods and heads out to fetch your things, but you grab her arm before she leaves. “Also, lose your clothes.” She makes another indignant face of shock. She must have thought the blowjob would be enough, but quickly realizes that she’s still going to have to get involved. She cold stares as she leaves, but heads to the kitchen area and not the exit.

You return your attention to Katherine. She is still waiting patiently on the bed. You pull off your shirt and toss it to the side, then cradle her chin under your curled fingers. She jolts in surprise, but keeps her eyes closed as you commanded. You move down her arm and take her by the hand. She lets you guide her fingers over to your body. First your chest, then down your belly. She smiles, realizing what she’s touching.

She eventually gets down to your cock.

“Oh… it’s already wet…” the petite brunette observes, rubbing your phallus and feeling the slickness from her sister’s saliva.

“Mmmhmm…” you reply. “Now, suck it.”

With her eyes still closed, Katherine feels her way towards you and settles on her knees to suck you off. If she tastes anything familiar or odd, she doesn’t mention it as she starts to lick and suck on your dick. You hold the back of her head to guide and direct her motions. She makes slurping sounds as she tries to keep your length down her throat. You’re getting good video of all of it on Katherine’s camera phone.

Soon, Sabrina silently enters your room, completely naked, as instructed. She glowers at you but is following your orders. She really wants to get back at her sister. You look back and forth between the twins. It is like you are seeing double! When you look at the young lady holding your ropes and the one sucking your dick, you can’t tell them apart! You get even harder. Sabrina hands over your items while she warily watches her sister, in case her sibling were to suddenly open her eyes. You give Sabrina a bit of relief by securing the blindfold onto Katherine, ensuring she can’t see. Katherine accepts the binds once again and awaits your next orders.
