Fuck her pretty little mouth

John stood up, pulling his jeans to the ground. "Get down on your knees" he commanded. Ellie did exactly as she was told, with John's imposing figure towering above her, his hard cock menacingly pointing at her face. "And get rid of that bra"

Ellie reached round and undid her bra, releasing her breasts. The smile on her face and the stiffness of her nipples suggested she was enjoying being ordered around.

John placed an arm around her head, holding her tightly in place. Their eyes met, before John suddenly rotated his hips and slapped her on the cheek with his dick. A look of surprise and anger passed fleetingly on Ellie's face. John slapped her again and again, alternating which cheek his cock struck. The look of surprised at John's behaviour passed from her face as she opened her mouth in expectation of his next move.

"Oh no, it's not going in there. Yet" he scalded her.

With his free hand John grabbed his dick and directed it onto Ellie's face. He pushed the tip of his dick slowly round her face, leaving a trail of precum across her forehead. Round and round he went, exploring every contour of Ellie's face with the head of his cock, teasing her lips with it but not letting her take it in her mouth. Once he'd had enough of this he put his other arm around her head and pulled her to him, tightly sandwiching his dick between his stomach and Ellie's face. Slowly he began to lunge, sliding his dick up and down her face, smearing her make up as he went.

Sam smiled inwardly. This was the sort of bullying and humiliating behaviour he knew that John was capable of. The sort of behaviour that Ellie might tolerate in the heat of the moment but would send her running when she came to her senses.

But Ellie was more than tolerating it. Once she got over the surprise of John's dick being pushed into her face she started to embrace the moment, lapping at whatever part of his cock was closest to her mouth with her tongue. John groaned in pleasure, enjoying the sensation of his penis rubbing against Ellie's soft face. After minutes of this he let her back away, with her head still in his vice like grip.

"Open wide" he grinned down at Ellie "it's time that pretty little mouth of yours got a good fucking"

Ellie parted her lips as instructed before John, still holding her head firmly in place, rammed four inches of his cock into her mouth. Ellie's lips instinctively formed a seal around his dick, as he withdrew and then thrusted again and again, each time sliding a little bit more of his penis down Ellie's throat.

As much as he hated seeing his step sister treated like this, Sam felt a sense of awe at what he was witnessing - both for the ferocity with which John was fucking Ellie's mouth and for the way that Ellie was managing to take his giant cock without ****. But she couldn't be enjoying it, could she?

It didn't take long to find the answer. Whilst John continued to pound her mouth Ellie slid her knickers down her thighs, spread her legs and started rubbing her clit in rhythm to the dick sliding up and down her throat.

Sam could barely recognise the woman he was watching as his sweet step sister. Here she was, her face a mess, naked except for her knickers down her hips, down on her knees and masturbate whilst having a thug ram his nine inch dick down her throat. But the evidence was there - the same girl who had celebrated her twentieth birthday with a unicorn themed party just weeks ago was now getting off on being sexually humiliated and degraded.

John continued to thrust his dick into Ellie's mouth, now so far in that his balls reached her chin when he thrusted, but suddenly withdrew. "Look at me" he bellowed causing Ellie to turn her head upwards, a smile across her face. He grabbed his cock and began dementedly jerking it just inches from her face. Within seconds he was cumming, spraying stream after stream of semen onto her.

John stood panting but victorious as he pushed his dick into Ellie's mouth one final time. He admired the mess he'd made of her, with more of her face hidden underneath his cum than visible, not to mention the amount that had landed in her blond locks.
