Aaron plays with 'himself'

“No point in rushing things,” Aaron whispered as he traced the line of Natalie’s body with ‘his’ eyes. Seeing the predatory expression on his big sister’s face as she checked herself out was almost too much, and Aaron felt his stolen pussy twitch as he made her hips sway in anticipation.

He took his time undressing her, dancing slowly back and forth as he removed each piece of clothing in a self-serving strip-tease. It felt unnatural at first, but as Aaron lost himself in the movements, he realised that Natalie’s body had an **** rhythm of its own. She probably did this all the time for her boyfriends, or even just to get off on herself.

That last thought sent a shiver up his spine as the bra came off and Aaron marvelled at his sister’s tits. He almost jumped as he brought her hand up to brush against them, the sensation sending tingles through his chest.

Starting instead at her stomach, he stroked her fingers slowly upwards until they danced against the underside of each borrowed breast. He traced wide circles outwards from her lower ribs, up to her collarbone to meet in the centre of her chest before bringing her hands down slowly to cover her nipples.

The warmth of her hands made him shiver again, and Aaron stared at the picture of artful erotica in the mirror as his sister stared back, her breasts covered by each hand in mock modesty.

With the beating of her heart pounding in his ears, Aaron slowly squeezed Natalie’s breasts, drawing in breath sharply as her nerves sent pleasure coursing into him. Rubbing, caressing, massaging, Aaron spent what felt like hours watching his sister feel herself up, never once looking away from her mirror-image.

Shifting his weight, he gasped at the sudden chill against his inner-thighs and realised that Natalie’s pussy had soaked through her red panties, leaving a damp smear between her legs. He shuddered when he peeled off the fabric, feeling the sensation of his lower lips in the cool air of the afternoon.

Again, he took his time, reaching down between his sister’s knees and tracing her hands up her thighs, drawing intricate patterns with the tip of each finger before caressing her lower lips. The intensity was shocking and he felt his knees go weak at the unfamiliar arousal.

Aaron pulled Natalie’s mirror over by the bed and sat down, legs spread wide to give himself a good view. In the mirror, Natalie stared back intently, molesting her own body as though she’d never seen herself naked in her life.

This time, Aaron savoured the sensation, feeling Natalie’s entire form tense and shiver as he worked her outer lips with one hand. Trace and slide, squeeze and spread, he watched his sister play with her pussy and luxuriated in every spark of pleasure, thrilling at the sight of her raising a slimy finger to her lips and sucking on it.

It didn’t taste like honey, but the sight of Natalie debasing herself and the knowledge that he was the one pulling her strings made it pure ecstasy.

He reached down again, two fingers poised and slowly, delicately penetrated his stolen pussy. It felt incredibly strange, to be penetrated like this. To feel the warmth of a pussy squeezing his fingers, but also to feel his flesh clamping down on a foreign intrusion; to feel his own fingers buried deep inside himself in a way that only a woman could experience.

And that was all it took. The knowledge that he had stolen his sister’s body and was using her delicate, dainty hands to finger-fuck her pussy filled the well to overflowing, and Aaron almost passed out as his stolen body spasmed and jerked on the bed.

He was gasping for breath by the time it was over, but instead of exhausted, Natalie’s body felt like a live wire. He’d tasted his sister’s body in a way that no-one but she had experienced before and he was far from finished with it.
