A couple of weeks later, Diana was well again and resuming her weekly gym exercises. This time, the laboratory had called her up again for another experiment. She agreed.

The thought of meeting the hot scientist, Troy, again thrilled her.

She walked into the lab at the schedules timing in a white tube dress and her underwear could clearly be seen through it. She was wearing a bright red lacey bra and matching panties.

"What're we going to do today?", Diana asked.

"Same thing, just a different way of experimenting", replied Troy.

Diana stripped down to her undies and went onto the cream-coloured cushioned lab table.

"First, we will measure the pleasure experienced through arousal from tickling in various places. Just relax.", said Troy.

Diana lay down on the table and waited. Troy took a long feather and a makeup brush and lay it beside the table Diana was lying on.

"Ready?"

"Let's start"

Troy connected the pleasure sensors to her neck, wrists, and belly. Then he pulled up her panties to reveal the crotch area, and continued sticking the sensors on. The sensors were also put on Diana's inner thighs as well as around the nipples and across her chest.

The monitor was switched on the Diana felt excited.

First was the feather. Troy used it to tickle Diana. When it went on the neck, she giggled. Then it went across her breasts and down the belly. The pleasure sensors went a little higher around those areas, Diana smiled. Then Troy teased the feather near her vagina and around her inner thighs, tracing the V-shape around her panties. The pleasure sensors went higher, and Diana went "mmmmm". Then, Troy, with his gloved hands, careful pulled the panties down and tickled Diana with the feather.

Diana's back slightly arched and her nostrils flared, enjoying the sensation. The pleasure sensors surged.

Troy then typed something on the computer. Later, he came back with the makeup brush. He brushed Diana's body all over with the makeup brush, and Diana sure was feeling aroused because this felt tons better than the feather and the pleasure sensors surged even higher than before.

"One last thing" Troy said, "I need to experiment with my finger as well", smiling as he said it. Diana returned his smile. Troy's gloved fingers felt extremely soft and smooth and very pleasurable to Diana. She closed her eyes throughout this entire experiment and started to have fantasies about Troy while he was caressing her. The pleasure sensors registered the highest with the fingers. "Okay done. Now for the next part. Please take off your panties. We're gonna have to insert something into the vagina." Troy said.

Diana did as she was told, and felt herself wet because of all the tickling and teasing from before.

The vibrator was brought out. Diana spread her legs automatically. The vibrator started doing it work, and Diana started moaning and feeling it. She started to get hot and wet and spread her legs wider to receive that pleasurable sensation. Then without notice, a rubber dildo was inserted into Diana slowly. Diana was pleasured, greatly.

As the dildo was moving into Diana slowly, it twisted it's way in as well. "Ahhhhhhh..." moaned Diana, attempting to spread her legs wider, her fingers scratching the cushion. The dildo was long, and it could vibrate inside Diana. "Oh! oh my... ahhhh..." moaned Diana when the vibration was turned on. The vibration started with a low intensity to a high intensity, and Diana's moans and gasps followed the intensities of the vibrations. She was grasping the cushioned table below her and arching her back repeatedly.

Then without warning, the dildo started moving in and out, twisting at the same time.

Diana gasps at the sensation, and the pleasure monitors surged the highest so far. "AHHH! OHHH!" screamed Diana, arching her back and clawing the cushioned table at the same time. She tried to open her legs more and push herself forward.

*GASPS* *GASPS* Diana was panting from the effort of pushing herself, but she was pleasured.

Troy then came beside her with the makeup brush and started to caress her area with it. "OHH! OHH TROY!" gasped Diana.

Troy stopped the dildo and started to strip. He was totally aroused and erect now. "Troy come into me now!" Diana gasped. Troy was onto Diana in a second, holding her waist and licking her chest. He undid her bra and flung it aside. Troy then started massaging Diana's breasts. "OH TROY come into me!" Diana screamed. Without a moment's hesitation, Troy penetrated her. Diana felt ecstatic at the sensation, she climaxed and arched her back even more while clutching at the table. "AHH! Oh my god Troy!"

The pleasure sensors were still on and it was going sky high.

Troy and Diana started to have hot and heavy sex. Everytime Troy climaxes and ejaculates, Diana with her arched back flared her nostrils and screamed with pleasure. "OHHH TROY! COME DEEPER!" This continued for about half an hour till they both got tired and fell asleep.

Troy was sprawled across Diana, and Diana had her hands and legs dangling from both sides of the table, with Troy still inside her.
