Yes. She restrains her little sister

You watch as Katherine tiptoes back over to the sofa bed and grabs a pair of handcuffs, some rope, a blindfold and a gag. Sabrina is watching this in her restrained state and her eyes go wide when Katherine moves silently back behind Emma.

You try not to tip Emma off as she continues to suck your cock. She’s trying her best to do it sloppily, using plenty of spit and making a lot of noise. Perhaps she’s trying to imitate a porn video, and although her inexperience shows and makes the gurgling sounds she’s attempting almost comical, it’s still extremely pleasurable.

Katherine quietly kneels down so she’s level with Emma. She has the handcuffs in one hand and with the other she grabs Emma’s wrist. Emma immediately pulls her mouth up off your dick. “WHAT ARE - AHHH STOP,” Emma screams. But it’s too late, Katherine has moved quickly and has the handcuffs already on her right wrist and is yanking the left arm backwards. Emma tries to turn but taken by surprise and from behind, Katherine has too much of an advantage.

You watch as the sisters struggle. Emma’s hands are handcuffed but she tries to get up and escape Katherine’s grasp. Emma has none of this though and catches her ankle, causing Emma to trip and face plant on the carpet. Emma let’s out a scream of pain at this and Katherine is soon on top of her, pinning her down and sitting on her back. She grabs Emma’s legs and toes them tightly together. She flips Emma over next and jams the gag into her mouth before finally putting the blindfold on.

Katherine turns over to you. She’s crying, tears on her cheeks, but there’s a determined look on her face. Earlier today you would have never thought Katherine capable of such a thing. “I’m so sorry Emma,” she says as she crawls over to you, not taking her eyes off your erect cock, “I had to do it.”

She leans over your cock and engulfs it with her mouth. You groan and shove Katherine’s head down, jamming your penis into her delicate throat. She gags and tries to come up but you continue to hold her down. Your orgasm is building and you let her up for a breath of air, watching her pant and gasp. You shove her back down onto your cock before she’s fully ready, and explode into her throat. You raise your feet off the ground and wrap you legs around her head, locking her in place with your dick shoved in her mouth. You pump stream after stream into it, surprised at how much is still left. Katherine is struggling hard now trying to come up for air. You don’t allow her to, and her eyes start to roll back. She’s almost limp by the time you finish, and when you let her go, she collapses forward onto you. You grab her and slap her awake, watching as she gasps for air.

You jam your fingers in between her legs and start fucking her with them. She screams in between gasps, “Ahhh — OHHH —FUUUUCKKKK.” Katherine’s orgasm is almost immediate and smashes into her like a brick wall, her legs shaking and buckling as she loses all control. Her orgasm is intense but you don’t slow down, jamming your fingers into her sensitive spasming pussy. In pleasure and pain she tries to jerk away but you don’t let her and she screams as her eyes roll back. She goes silent as she passes out yet again, this time from her brutal orgasm.
