Babysitter - Part 4... Don't you make me cum inside

This sends a shockwave through my body. 'Go ahead and ride it' he tells me so I start to rock my hips as it moves inside me. It's hitting all the right spots as I get wetter. My eyes are closed and all I can focus on are my own contractions, feeling his cock from the inside... every inch of it. He hits my spot and I start to squirt again, head flailing about. He laughs at me and keeps pushing me down on him. I can tell he wants to cum, to fill me up with his semen but he holds on. Pushing me aside before he does, his cock comes out of me dripping. 'Wait, I have something for you' He disappears for a moment, getting up with his hard cock still pulsating in front me. He comes back with some kind of vibrator and sits back on the sofa. 'Alright, get back to it' so I straddle him again and sit down on his still throbbing cock. At which point he takes this device and slips it between my legs pressing against my clit. Turning it on, I jump but he quickly grabs me and pushes me back down. Again all I can say is 'Oh god' shaking and trembling. I think he jumped straight to the highest speed and I can't take it but he makes me take it anyway. As I move up and down my clit vibrates rippling throughout my whole body.  
 
I just keep grinding against him, everything soaked. 'Don't you make me cum inside you' he says meanly. I just keep going with my orgasm, my body moving to it's own rhythm to try and accommodate the sensations blowing my mind. I think the only end to this torture is for him to shoot deep inside me. Like a true slut I want that, to know what that feels like. He said 'Stop' as he pulsates more in me, so hot and big. He lets out guttural moan pushing me but it's too late. I feel him start to pour out as I plunge down again. 'No don't' I whimper agreeing with him not to cum inside. But it's too late, he cannot pull out and I cannot stop taking in his fluids in my tight pussy. He keeps cumming inside and as I start a new orgasm, so incredibly sensitive like nothing I have ever felt. He spreads my cheeks and inserts a finger there again stroking me. 'You little bitch, you are going to pay for that' he manages to mutter still pouring out inside of me. I just fall against his chest taking in the last shots. He pushes me off again saying 'clean that up' so I take his cock in my mouth, sucking it in deeply. Draining the last fluid out of it as his body is overwhelmed by the sensation.
