She gets stuffed again

Mei watched as the mechanical arms brought out a new dildo and attached it to the thrusting arm. The new one was slightly bigger, at around 6 inches, which was starting to make Mei a little more nervous. The biggest thing she had ever shoved up her snatch was 7 inches. She had bought a suction cup dildo and lowered herself onto it, though it was mostly gravity doing the job as her legs gave way. She ended up cumming pretty much instantly and just sat there on the dildo. Now her invention was about to thrust in and out something which wasn’t a whole lot smaller.

“Well, it’ll be good to get this experience now so I can get used to more tests in the future… yeah I’ll use this as a learning mome-OOOOOOHHHH!”

Mei’s learning moment quickly arrived as she learned she had no stamina whatsoever. She was still coming off her high from the previous orgasm so even the slow movements of the dildo now were enough to elicit a loud moan.

“Oh, oh okay, I can do this, slow breaths… One, Two, Th-Three, F-Fo-F-FUUUUUUUUCK!”

Mei spasmed as she came for the second time. However, because Mei had programmed the machine to stop thrusting after the experience was over during the main thrusting phase and not for the starting sequence, the arm actually sped up for a bit before slowly decelerating and pulling out, leading to a much more intense and extended orgasm than before.

Mei was huffing and puffing from the orgasm, and her clothes were drenched with sweat.

“Ohhhhhhh, okay… huff, huff, that was intense… gonna need to practice with something smaller to build up stamina first I guess…”
