“I’ll let you go if you can count to 100 without making yourself orgasm. If you orgasm, you’ll have to start back at zero.”

That was the challenge he’d set for her and it seemed impossibly easy. All she had to do was pretend she was masturbating and start counting.

But both proved to be more difficult than she’d envisaged.

Not touching her pussy was particularly difficult. She seemed incapable of not masturbating, and was determined to give herself a good time during his silly challenge.

At first, things started going well. She shot through the 10′s, 20′s, 30′s and was going through the 40′s when she started struggling.

“49… 50… 51… 50… 49… Er… 48? Wait… Um…” she stopped counting, realising she’d begun counting back down. After a few more seconds, her cheeks flushed, and her nose tingled as the first orgasm hit. She couldn’t deny that it felt good but hated herself for it.

Sighing, she started back at zero. This time, she was into her 30′s when she hit trouble. She stopped counting as she worked out where she was, but her hands continued unabated and soon another orgasm hit.

Again, back at zero, she tried again. Barely into the ‘teens when she began counting backwards before finally orgasming.

She can’t get higher than five before she finds herself counting backwards. Now, when she reaches zero, she orgasms, feeling another part of her mind go *pop*.

He sat, smiling down at her as she cums herself into blissful mindlessness, waiting for her to stop counting and ask him what to do next.
