Her Big Ass Makes Him Cum

Tags: , cumshot, big ass, loser, domination, humiliation, face sitting, pussy, orgasm, femdom, handjob, rimming, pussy eating, cum, cunnilingus, milking, ass, black, bdsm, oral, face sitting, masturbation
Description: Goddess Amelia is standing over her slave rubbing his balls and saying he has been such a good boy all month and maybe today she'll let him cum. Instantly she slaps his balls and says "Or maybe I'll give you a ruined orgasm or not let you cum at all." Good to keep slaves guessing. The camera catches Amelia's back side as her luscious big ass comes down on the slaves face. If she is going to let him cum he is going to have to give her a proper deep rimming first.She sits firmly blocking all air ways and wiggles her ass at the same time. She leans forward and makes the slave reach to get his tongue in her ass as she strokes his cock. She pours lube in her hands and strokes his cock with it getting the slave very excited. She reminds him she hasn't decided if she will let him cum or not. She strokes even more vigorously and soon he is begging her to let him cum. Nothing more pathetic than a begging slave... or more delightful. The entire times she sits on his face only giving him a breath occasionally. She tells him to stroke himself and says he has 10 seconds to cum, if he fails he will wait another month. The desperate slave screws up a bit on the timing, that will cost him, but none the less he does blow a load all over himself. Amelia scoops it all up in her fingers and sticks them in his mouth. Slaves must always eat their cum after ejaculating. There's a lot of cum though so Amelia claps her hands and calls in her other slave to lick the cum off his balls as the scene goes to black. Imagine it's you she is calling in, if you're into that sort of thing!

Girls Team Ballbuster - Naughty Little Ball Breaking School Girl

Tags: femdom, humiliation, kick, ballbusting, domination, face sitting, 69
Description: Hey Boys, Summer Jones here, and I'm back at Girls Next Door Studios to play out one of my ultimate fantasies; Squashing my annoying older step brother's Nuts! In this skit, my step bro is babysitting me, and keeps on hassling me to get off my phone and get out to get some exercise. He should really know better than to bug me, as this isn't the first time I've kicked him in his Balls for being a pain. LOL. He keeps on bugging me, so I really have no choice but to beat up his balls a bit. After I slam my foot into his Nads he suddenly starts talking a little bit higher, it's freakin hilarious. He wants me to get more exercise, I think Ball Busting is Great exercise! I attack him with Kicks, Knees, Punches, Grabs, Gaspedals and Stomps. He tries to cover up but I just pull his hands away and Smash his Nuts repeatedly. He threatens to tell my step-mom on me, but I know she'd totally take my side. Heck, my step-mom taught me to kick boy where it hurts, if he told her what I do to him when he bugs me I bet my step-mom would laugh and give me a high five! In fact, if I gave her my puppy eyes I could probably get her to help! BAHAHA! I really get into it, and totally aim to Ruin his Testicles. He tries to be a “good step-brother” and doesn't fight back, which I think makes him even more pathetic as I'm clearly targeting his Manhood for Destruction!

Tags: face fuck, socks, pussy, face sitting, foot, sweaty feet, foot fetish, femdom, fucking, white, ass, face sitting, domination, , fetish, brunette, humiliation, tease, smelly feet, feet, boots, ass licking
Description: Sammy seemed really comfortable sitting on my face, but she felt like she needed a little more inspiration! She told me that if I stuck my tongue between her buttocks, it would probably inspire her a little more. So she decided to take off her underwear, and made me smell them in a very dominant manner. She also took the opportunity to make me smell her stinky white socks, and sat on my face again. This time, I had her vagina and butt directly in my face! She asked me a few times to stick my tongue in her asshole, and also asked me to lick her pussy! I must say that obeying her orders excited me more and more! She seemed to really enjoy my tongue movements in her pussy! She changed positions a few times, so as to sit on my face from the front, and then from the back, and some camera angles are really very sexy! At one point, Sammy asked me to push my tongue a little deeper into her asshole, and she started blocking my face between her two buttocks with her feet. I had both of her feet behind my head, and she seemed to be pushing with her feet to push my nose and tongue even deeper into her asshole! I was so hard, but at the same time, I had a lot of difficulty breathing! Sammy spent over twenty minutes sitting on my face completing her Amazon wishlist, but at one point she had a strong urge to . She turned towards me, asked me to open my mouth to tease me, then she went to the bathroom. What a wonderful Face-Sitting session!

Description: Mlle Fanchette is fully dressed, in a pencil skirt, black top and heels, and butler Boris is standing next to her naked with a semi-erect cock ready to service his Mistress. This is familiar scene in Mlle Fanchette's premises. Mlle will edge him and reward him with a ruined orgasm. She gently tickles his balls and cock until it becomes fully erect and then starts to work on it the way she only knows. Little slaps, fleeting caresses and slow firm jerking increase the butler's arousal. When she has him where she wants him she makes him work for his release by letting him fuck her soft palm. The butler is ready to explode and after a few last strokes Mlle takes her hand of his cock leaving it pulsating in the air before it starts to spurt jet after jet of fresh warm cum on the floor. Mlle Fanchette is once again satisfied by her loyal butler's performance. More like this: Edge ' Ruin

Which most women would consider tall but to me he is puiny and the only thing even weaker than him is his balls.
