A quick test.

You tried to look under your blindfold, but Crystal's handiwork ensured that you were now cut off from sight, at least for now. The sound of shuffling fabric was slow, as if decisions were being contemplated with each fiber being moved around. A light hint of potpourri and a waft of Crystal's sweat crept under your nose like a low, humid steam over a lake. Having resigned yourself to close your eyes, you let the rest of your senses try to figure out what was going on. Crystal's presence edged closer, made apparent by her aroma starting to take residence under your nose. She voice spoke sotfly, yet intently, through the impure haze that had formed.

"We're going to do a sense test. First I want you to touch; don't tell me what it is, just use your hands for now."

Crystal reached down and picked up your arm, as your hand was guided onto what could only be described as a soft, fleshy pole. Obliging your sister and succumbing to the lust that had been catalysed by her 'experiment', you squeezed softly, and ran your hand up and down length. The soft, thick skin pulled back and forth with ease over what felt like a massive head. Crystal's cock beat with an unnerving pulse; her groans, although soft, were apparent as her fat cock slowly rose to life. Unable to see, your brain was spiralling with the image of Crystal coming up to you in the bathroom.

"That's good, Dougie." A hand was felt over yours, gently pulling it off of the veiny rod, before the smell of sweat returned, accompanied by a thick bush of hair being pressed against your face.

"Now we're onto smell. Don't say anything, but just inhale." As your sister finished her instruction, the hand that had guided yours had wrapped itself around the back of your neck, and pushed your head with an air of 'I'm voluntelling you to do this." Her odor ebbed under your nostrils, a lewd and heavy heat that rested on your face like a soft blanket as the thick hairs found their way inside your nostrils. The darkness of your blindfold accentuated the smell; of each hair clinging against your face and delivering a touch of Crystal. Suddenly, a methodically slow, wet sound presented itself, almost on cue.

"Let's combine a few senses. Listen to this, but keep smelling." Crystal's voice was still along that line of clinicality, yet in her tone, you swore you picked up a similar falter to the one Lisa had the night before. The sound continued as the sloppy wetness increased in volume. The distinct *schlick* of a thick cock being stroked next to your face was clear as day, as Crystal tried to muffle her soft groans with little efficiency. The odor coming from her bush left a soggy kiss on your face, as Crystal began to get into a groove. The methodical *shlick* began to increase in pace, as she rubbed her hairy mound against your lips and nose.

"O-okay, Doug. Now we're onto the last sense. Time to taste." Crystal's voice was fully breaking as the sensualities of the test chipped away at her resolve, leaving her lustful core exposed and pulsating. Her thick and pungent bush abruptly removed itself from your face, and for a second, you were left devoid of senses. Slowly, the smell of sweat wafted under your nostrils once more, this time, accompanied by the presence of the same pole that you had felt earlier. It emanated heat, and, from your perception, was presenting itself at your lips expectantly. Crystal edged forward, causing her large, fleshy cockhead to softly prod against your lips before retreating; a thick glob of precum leaving a messy reminder of Crystal's desired entry.

"Lick your lips, Doug. Taste me." You slowly stuck your tongue out and let the thick fluid sit on the tip of your tastebuds. The same, now familiar smell of potpourri and sweat greeted your mouth, but a sweeter taste spread through the rest of your tongue as her fat girth once more greeted your lips; this time, not retreating. With her precum sending a rush of lecherous energy through your body, you opened your mouth to allow her cockhead entry to your mouth. Crystal shook with pleasure, emitting a soft, low groan. She left the tip of her mast in your mouth, allowing you to taste every bit of precum that secreted with every pulse of her massive cock. Suddenly, she retreated, and the sound of spandex signified the full withdrawal of your sister, as the taste of her girlmeat lingered on your tastebuds.

Your blindfold then fell, unceremoniously, as Crystal deftly untied the tight knot behind your face, before sitting down next to you on the couch. Her face was reddened immensely, a fiery contrast with her now frazzled blue hair, and you could tell that she was summoning all of her willpower not to pounce on you then and there.

She looked at you, lustfully, the energy between you two nigh tangible, before taking a moment to settle herself, before putting her hand on your cheek.

"As hard as it might've been to believe, this actually was a test. Doug, there's something you need to know."
