Finish the Handjob

Deciding that he shouldn't go to far in his first experiment, Andrew once again grasps his still erect cock in his hand. No longer consumed by lust Andrew starts much slower truly drinking in every minuscule action his cock makes, every sensation he once ignored. He feels the slightly warm heat of the desk on his balls, sure that his sack had warmed the surface overtime and that when he started the first time he should have noticed a slight chill of the cold desk. Was he too absorbed during the first experiment to notice or had it took awhile for him to regain feeling in his testicles? Something to check during his next session it seems.

Speeding up his strokes along his shaft, Andrew takes his other hand and starts caressing his balls. Feeling the weight of his sack in his fingers and the slight shiver of his cock in the other while he stared at the ballsack, watching how they moved under his skin trapped in the bag below his cock. Increasing his speed Andrew feels precum leaking from his tip as playing with his balls increased his arousal. Smearing the precum all across the sensitive tip and down his shaft wetting his hand. Feeling his sack begin to tighten as the pressure builds in his pelvis, his cock engorging as he feels his ejaculation getting closer.

What was once long deep strokes from the tip of his cock to the base have instead become frantic mini strokes around his sensitive cockhead bringing Andrew closer and closer to cumming. Andrew's breath has become short and quick, his body becoming taut, the building pressure in his cock has become unbearable. Andrew knows he is moments away from cumming, fighting the urge to lean back and lose himself in the ejaculation he instead steels himself into not looking away from his penis in its moment of eruption, wanting to capture every detail to see if he could spot any differences in how it was before his mishap today.

"Ugh" With a grunt Andrew finally starting ejaculating, his eyes never leaving his cock not even blinking incase he missed the smallest detail. He saw his balls tighten and the initial pulse that started from the base of his cock, traveling quickly to the cockhead. The first spurt sending out a thick glob of sperm into the air and getting a little on his hand. The heat of his sperm on his skin, the wet sticky liquid on the back of his hand and in-between his fingers distracts Andrew momentarily before he sets his gaze back to his penis. The second eruption followed quickly after the previous with the same intensity as the first seemly of the same amount as well. Watching his cock continue to pulse over the next few seconds and with each pulse letting out another wad of semen before slowly dying down. Andrew finally allowed himself to lean back and close his eyes, relishing in the final throws of his ejaculation. Catching his breath and feeling the stress slip from his mind and body Andrew slowly composes himself and takes a look at the clock.

"Shit" Andrew grumbles realizing that his experiment took to long for him to shower before running of to dinner. Instead he would have to make due with washing his hands and cleaning his now completely covered desk before running off to meet with his friends for dinner.
