She wants you to swallow her cum

As she pulls out of your mouth a string of saliva breaks from the cock and falls back to your chin. Leshaun slowly strokes her cock in your face pondering what to do with you. She starts slapping your face with her cock as she states "I think I'll just use this pretty little mouth of yours until I am done instead of fucking your tight ass. And when I'm done you better not waste a single drop of my cum or else". Hearing this made you slightly nervous but you need your book back. She goes to lay on her bed with her legs spread and her wet sloppy cock waiting for you. You start to contemplate grabbing the book and just sprinting towards the door but you were worried she might hurt you so you make your way to her bed and lay down to where you are facing her cock. "Go ahead, put it in your mouth slut" she demanded. So you start to put her cock in your mouth and she closes her eyes and starts moaning. Seeing her this **** however makes your cock stand up and you start to hump the bed a little. You keep sucking and massaging her balls with her hands in an effort to make her cum faster because you want to leave already. She keeps moaning and gripping the sheets so you are starting to think it's working. She then abruptly stops and says "all the way". Confused to put a little bit more into your mouth. "Keep going" Leshaun requests again. Once you get about half of her tasty length in your mouth she uses the opportunity to wrap her legs around your neck. You are now locked with cock in your mouth and your only hope of breathing is when you can pull her out far enough for your nose to take in air. "That's better. Wouldn't want you to think you could leave" she says. She then starts aggressively bucking her hips so she can really start fucking your throat. It's starting to get more difficult to breathe you are hoping she finishes soon. You move your hands to grab her thighs in an attempt to loosen her grip on your head but it doesn't work. She goes back to moaning and gripping the sheets now so you suspect she is getting close. You squeeze with your tongue the underside of her cock to try and make her shoot sooner. Then without warning she groans loudly and locks your head with her thighs all the way until her balls are against your chin. You feel it twitch in your mouth as it starts pumping down your throat. It's so deep that you don't taste any yet. After 5 or 6 pumps though you start to feel full and can't swallow anymore. A little starts to pool in your mouth and the taste is intoxicating. After 8 more pumps into your throat her now flaccid cock falls out of your mouth. Some cum still on her member and some escaping your mouth and landing on her beautiful belly. Instinctually you swallow what you have and move to her stomach to lap up what remains. "That's a good little slut" she says as you start to clean her cock of the remaining cum. Leshaun then says "we almost had a problem considering you didn't swallow all of it at first. I guess you are off the hook since you fixed it. Anyway go grab your book and leave. Remember, I am in charge so don't even think about doing anything stupid like telling people what happened here". "I won't tell anyone I promise" you say quickly out of fear and mostly because you just want to get your book and leave.
