The rollercoaster was running again. The team strolled through the amusement park, celebrating that their work was done. The night embraced them, smelling like popcorn and cotton candy, chasing the recent horror away.

"Who dares to ride the rollercoaster with me?" Grissom asked in high spirits.

Greg giggled madly, even Sara repressed a smile.

"You have way too much imagination," Grissom scolded both of them.

"Do we?" Greg provoked him. "As far as I remember you were the one who told us that the release of epinephrine and adrenaline while riding a rollercoaster can produce a stimulatory effect."

"That was a sheer hypothetical declaration," Grissom grumbled, slightly embarrassed.

"Yeah, right!" Greg continued to tease him. Nick, Warrick and Catherine were shaking with laughter.

They passed the entrance of the rollercoaster. Grissom didn´t mind the banter and climbed the steps anyway. "Who is coming with me?"

"Not us," Sara and Catherine said at the same time.

Nick and Warrick shook their heads, still laughing.

"Count me in." Greg jumped up the steps while he was searching his pockets for money.

Grissom stared icily at him but didn´t say no. A minute later they climbed into the last wagon. The ride began. Their friends waved. "Have fun!"

"What were you thinking?" Briskly, Gil tipped his finger against Greg´s chest.

"Why?" Greg cheered frolicsomely. "I haven´t done anything yet."

"And you won´t."

"Says who?"

"Pull yourself together," Grissom railed at him. "You´re not eight years old."

"No, but I like to sample this pleasure to the limit."

"What pleasure?"

"Taking a ride." He leered and spread his legs as far as possible.

"Don´t you dare."

The peak came in sight. A bright sign blinked: Keep your hands inside. Don´t stand up.

"That´s fine with me." Greg opened his zipper. "I just need to get my juices flowing."

"GREG!"

The rollercoaster passed the peak. Greg started rubbing his very own train.

When they were running down, Greg´s sighs and whimpers were teasing Gil´s ears. "You are kidding, right?"

"No." He bucked his hips, showing off, while the train raced through the first looping.

"This is...outrageous...even for you!" Grissom screamed to drown the noise.

Greg moaned explicitly. "But I need it now."

"You can´t be serious?"

"But I´m hard. You - scolding me - makes me even harder."

"Damn!" Gil swore. "Stop at once."

Greg didn´t listen but continued taking care of number one. "Oh yes - shout at me - make a fantasy come true...."

The train rushed through the second looping. Greg enjoyed the rhythm, felt the rhythm, moved with the rhythm, screaming exhilarated. "Oh...Gil. I´m close...so close...."

Grissom gulped. "Oh...Greggo." For heaven´s sake. How could he know this turns me on? How dare he...take this...challenge....

The train was racing along, taking the curves, bending against the pressure, fighting, fighting, coming down in a soft flow. The liquid spurted from Greg´s cock. "I´m coming...oh...oh yeah!" His body was shaking like the wagon in which they rode, shaking, shaking, shaking.

The rollercoaster returned to the beginning, ready to start over.

"This was a successful experiment," Greg declared huskily. Casually, he put his cock back into his pants and pulled the zipper up. It gave him the greatest pleasure to see his mentor baffled speechless. Smiling brightly, brown eyes glazed over, he waved at their friends. "Awesome ride!" He started to get up but Gil pulled him back. "No, no, be nice."

"Nice to whom?" Greg grinned naughtily.

"Every experiment needs a rerun to prove it was correctly done."

"Really?" Greg kissed him on the way up, kissed him to get it up.

Their friends waited, chatting sprightly, they didn´t care what was going on above them - yet.

In the second run, the train flew as smoothly as the first time, taking the loops in perfect circles. Gil went off with flying colors; Greg did him the favor to lick his rails clean. Once again, the train slowed down, satisfied and smeared, ready to roll again. But for today the ride was over.

"So?" Catherine asked, smiling viciously.

"A rollercoaster ride truly enhances ejaculation," Greg blurted, bubbling over with sensation.

"Shut up," Grissom groaned, crimson.

Just now the case was truly closed.
