I woke to a warm, wet sensation on my cock and the duvet bobbing up and down.
I lifted the covers. "Morning, babe!"
"Morning, sleepy head" laughed Sarah from between my legs, "I wondered if that would wake you up. Now, lie back and enjoy this. It's your turn."
She took my cock into her mouth and slowly swallowed the whole thing. I'd watched her doing this before but I loved to watch her take me deep into her mouth and throat. How she did it without choking I didn't know, nor did I care how she'd got so skilled at giving a blowjob. I was just doing as I was told and lying back and enjoying it.
"Mmmm, that's good, don't stop."
Sarah pumped my cock with one hand, alternating strokes with her mouth, and massaged my balls with the other. I could feel my cum building but just as I reached the point of no return she stopped and looked up at me.
"I've been thinking", she said, still stroking my length. "About that video we watched"
"Which one? The threesome?"
"No, the one with the chair. I want you to do that to me. Tie me to the chair and play with my tits. Play with my clit and make me cum but you'll be in charge. I want to be helpless. Cuff my hands behind the chair back, tie my ankles to the legs and you should probably tie my collar to the back of the chair too. You can do whatever you want to me. You'll have to gag me too because I want you to make me scream." She bobbed her head down onto my cock. Once. Twice. "What do you think to that?"
