Interrupted by his sister

"Adam, i'm home!".

He heard his sister Sarah close the front door.

Only yesterday the thought of his sister catching him half naked, with his cock out, would have been most embarrassing for Adam. Now, with his sexual morals eliminated, it made him even harder, if that was possible.

"What is that intoxicating scent?" Adam heard his sister asking, seconds before she appeared in his doorway.

Adam checked out his sister:

She was a short, but fit blonde, with curves in all the right places. And she was wearing her incredibly sexy cheer-leading uniform: Knee-high boots and a skimpy skirt showing off her toned legs. Above the skirt, on her exposed midriff, Adam could detect a hint of a six-pack. Further up: A push-up top, producing an impressive cleavage and emphasizing her c-cup breasts. Almost waist-length long straight blonde hair. A pretty face.

Sarah was biting her lips and her bright blue eyes were wide open, captivated by the sight of Adam stroking his huge cock, leaking precum. The scent of it further hypnotizing his shocked sister.
