SDJS-222 - Repeated restraint and continuous ejaculation durability testing resulted in numerous puddles forming in the office. Six carefully selected female employees experienced urinary incontinence to the extent of changing suit colors, with stretched underwear, straddling, and analysis of ejaculation mechanisms and anatomical responses. Sexual Science Lab Report 17

We got to see six women climax, and it was fun how some were just going non-stop, while others had a huge burst at the beginning but faded later, or vice versa. Though, in the scene with all four of them together, it would've been way hotter if they'd all taken their pants and skirts off and just been experimenting.

The scrotal vibe fixture was way too loose, so they ended up having to hold it in place with their hands. It really cuts the effect in half, honestly.

This feels like something only real enthusiasts would get. It's not just generally fun, it's like women are *studying* women, and there's zero hesitation – they're just going wild with vibrators and the moans are echoing everywhere. The fact that the 'research subjects' and the researchers are all actresses makes it feel more like a genuine study, which is a nice touch. Definitely makes me want to check out other stuff from this series! Absolute masterpiece.

I own a few titles from the Sex Science Lab series, which feature women being restrained and stimulated with fixed vibrators under the guise of 'experiments.' Sometimes, guys claiming to be male researchers would join in, and it would get awkward – even devolving into manual stimulation or actual sex, which was a real letdown. From the subject's perspective, it's embarrassing to be getting intimate with a same-sex researcher under the pretense of an experiment, and the shyness disappears, making it less interesting (and let's be real, sometimes the guys were just visually unappealing). This time, though, *everyone* is female, including the researchers, which is a huge relief and fantastic. All four subjects are 'attacked' in a similar pattern, which is a bit repetitive, but their movements, reactions, and moans while restrained all have their own unique flavor. The scene where the second girl breaks the collection dish during a doggy-style assault is particularly good. The four-way standing restraint in the latter half is a symphony of moans, and the final scene with the female researcher becoming a subject herself is a nice touch. My only complaint is that the upper bodies of the women were covered (understandable, given it's an experiment). Anyway, I'm begging the producers to keep the restraints and fixed vibrators, perfect new types of stimulation, and continue with an all-female cast. Five titles a year, please! I'll buy everything, including backups for preservation. This is a must-have.

I like seeing women tied up and given a hard time. In this installment, researcher Makita Tsubasa was really cute. She's got that something special. I'm gonna check out their other works. Definitely worth keeping!
