Her time runs out and she’s not happy

Katherine glares at Emma and then turns back to face you. She whispers into your ear again, “I’m your little slut master for the next half hour. Would you like to relax and let me play with you? I know you must be tired down there but don’t stress, you can relax and let me gently help.”

“That works for me Katherine,” you respond, “just don’t expect me to actively participate. I’m going to be watching TV.”

Katherine’s face drops slightly at this, knowing you won’t be giving her full attention as she tries to work your cock. But the grim look of determination on her face is unmistakable. She’ll do what it takes to make sure she doesn’t end up like Emma - chained up, sobbing and anally destroyed.

Katherine spends the next nearly half hour licking your balls, your shaft, and sucking your head as you sit in John’s armchair. You enjoy the feeling of having her mouth slathering your cock and you do manage to get hard again, although your erection does not mean you are close again to orgasm. It’s certainly a rush of power to watch as the shy, soft spoken and kind sister of the group tries her best to please you, all while you pay little attention.

Emma who is resting with John on the soft bed suddenly looks over. “You have two minutes Katherine and then it’s my turn.”

Katherine’s eyes flash in panic and she tries to work harder. She attempts more dirty talk and whispers up at you in her sultry voice, “sir will you please cum all over my face? It would be such a nice reward for me.”

But soon time is up and Emma demands Katherine get up. Katherine reluctantly let’s tour cock fall out of her mouth and she stands up and steps back to let Emma kneel down in front of you. You sign as Emma immediately takes you into her mouth. “Aren’t you ready to cum in my little mouth and let me swallow all of it?” she asks, “I’m so happy my sister got you all ready for me, but she failed again and now I’m going to be rewarded with your cum right master?”

You watch as Katherine looks at Emma in anger, still standing just behind her.
