Vi and a man

I almost can't believe my eyes, did the extra time it take me turn them on more than she planned? Or did she jump straight into this? Vi's eyes are closed, her mouth open in pure ecstasy, the sight before me the only thing I can see, the rest of the party fades away. I groan as see my girlfriend being groped by this man in the middle of a public party, Vi's lips quiver as the hand on her breast squeezes, the mans face buried in her neck, no doubt sucking and kissing her supple skin. She's got one hand in his hair, pulling him close, her legs parted and her thigh hitched slightly upwards, with every grind I can see it, this mans bulge pressing into Vi's pussy. Fuck, How wet would she be right now? I breathe heavily as I watch dumbfounded by the scene in front of me. This is what I wanted, it is one of the sexiest things I have seen in my life. I watch as Vi subtly turns her head as the man tries to kiss her lips and in doing so spots me in the crowd.

Her expression doesn't change, rapt in pleasure and lust, her supple parted lips, her hooded eyes. I watch as she reaches forward and grazes the mans bulge with her fingertips, my breath hitches, the sides of her mouth pull into a slight smirk before she lets her hand drop away. I see her face shudder and her eyes close as the man squeezes her breast again, she pushes her chest into his hand as the other reaches around and grabs a handful of her ass.

My fully erect member tightens my pants, I can't take my eyes off the scene in front of me, I want to fuck her now... But I also want to keep watching. Vi knows I'm watching now.... how far will she go? How far do i want her to go?
