SONE-026 Retro-Review: Three Days of Endless Titty Fucking with Horny Boss Washio Mei

SONE-026 stars S1’s Washio Mei as a strict but secretly insatiable boss who spends three straight days draining her subordinate dry after one drunken business meeting. There are 4 scenes with a total of 7 paizuri cumshots. This one ended up being a very pleasant surprise that completely slipped under my radar back when it was released.

Movie Review
Scene 1 – Titty Fuck + Sex (2 TF Cum)

Scene 1 starts with some story setup where Mei catches the guy looking at smut at work (RION’s boobs to be exact) and jokingly forbids masturbation for a month. Fast forward after a successful business meeting, the two of them continue drinking together at her house before her exposed cleavage finally pushes his pent-up lust over the edge. He devours her breasts and then pleasures her with some fingering and cunnilingus, before getting his turn with some blowjob and a titty fuck to completion. But a month’s worth of frustration isn’t so easily sated as he’s immediately hard again and goes right to fucking her pussy until he blows a second load between her boobs.

Very good start with Mei-chan being mostly naked for most of it. She started a little hesitant but once his dick was inside her, she completely gave into the moment and the chemistry really took off. Both paizuri segments also looked great despite being in the straddling position which I prefer somewhat less. Both money shots were also decent with a spurt of semen visible, though the first one was a little awkward where he was holding his dick in mid-air for a few seconds, almost like when you’re jerking and trying to prime yourself for a big shot.

Scene 2 – Blowjob + Titty Fuck (1 TF Cum)

Scene 2 sees the couple stepping out of the bathroom, and Mei already can’t keep her hands off him as she strokes his penis while he’s toweling her dry. She then drops to her knees for a blowjob before finishing him off with a titty fuck.

Short and sweet outercourse scene. Mei-chan being fully naked again certainly didn’t hurt either, but what really stood out was the 180 her character has taken from being passive in Scene 1 to now the slutty boss taking control of his dick. The paizuri was pretty good at almost 5 minutes long, and the climax looked great with the guy squirming his hips and twitching his penis. Sadly the cumshot was quite weak and hard to see from that position, though the earlier double finishes helped reinforce the fantasy of getting drained. If only we could have seen just a little spurt of semen (curse you mosaics 🤬).

Scene 3 – POV Titty Fuck + Sex (2 TF Cum)

Scene 3 sees Mei stroking the guy’s spent dick on the bed, still horny for more. The scene then switches to a POV perspective, where she serves up the usual foreplay combo of breast fondling, nipple teasing handjob, blowjob and titty fucking. We naturally blow our load from that paizuri, earlier than she would have wanted, and so she gets on top for mostly cowgirl sex ending with a second cumshot between her tits.

The POV fantasy was a huge improvement compared to Scene 1, though the double cumshot here was much weaker. The first one barely had any visible semen, and from Mei-chan’s surprised reaction I suspect it was a non-scripted premature finish. Not that I blame the guy at all. The second one at least you could see a sliver of semen in her cleavage, but it was a last-minute pullout from missionary without any proper straddling at all.

Scene 4 – Titty Fuck + Sex (2 TF Cum)

The last scene sees the lucky guy on the 3rd day of his “sex marathon”, still getting his soul sucked out of his dick by Mei. She pleasures him with a variety of blowjobs and handjobs before titty fucking a first load out of him. They went back to some foreplay with Mei getting fingered and then giving him a breastfeeding handjob, before continuing with intercourse sex ending with a second cumshot between her breasts.

Another solid double-cumshot scene with Mei-chan once again spending most of it fully naked. The first cumshot was again quite weak, but at least this time you can see some semen dribbling out from the penis clenched between her boobs. The second one was much better with a nice spurt shooting all the way up to her neck, but it was yet another one of those last-minute pullout finishes.

Summary
This movie completely flew under my radar when it first released back in 2024, and I was so happy that I picked this up for our series of retro reviews. 3 double cumshot scenes which regular readers will know that I am super high on, and as far as I can tell most of them looked real as well.
They aren’t explosive by any means which is pretty typical for S1, but here’s where context matters. In an unrelated split-scene “Titty Fuck Situations” movie? Underwhelming sure. But when there’s a proper story being told about a busty, insatiable beauty milking us dry with her boobs? Hits much different and these are pretty much “jerking crack” for me.
Mei-chan’s performance was also great for wasting zero time transforming from the strict but kind superior into a slutty fuck buddy. The production was also well done with plenty of nude action. In fact this actually reminded me a lot of Madonna’s “I Made My Mother-in-Law Pregnant” series, which makes sense when I found out that they are from the same director.
Overall a very pleasant surprise and I’m baffled that this concept wasn’t explored further, and instead we got S1’s other female boss series whose recent entries has been nothing short of disgraceful in comparison. As far as I can find, there was only this release and Nagi Hikaru’s SSIS-742 which I immediately added to my review backlog.
And that wraps up our second feature for this little “Washio Mei Appreciation Corner”. There are still a few more planned within the next couple days so stay tuned for that. And there might just be a little hint above about one of the retro reviews coming soon 😉.

-
I can’t believe S1 only had two movies made from this series. ONLY TWO MOVIES? What the fuck? As much as I highly-recommend this series so fucking bad, why did the studio had to quickly retire the series to the grave? This would’ve been the chance for the likes of Haru Minami, Yu Tano and Ako Kimura to flaunt their “weapons of mass destruction” to good use with a proper storyline. 🤭
This was surely one of Mei Washio’s best, if not THE best, tittyfuck movies of her career. Part of it was thanks to who directs the movie. Director Mametaro Mamezawa may not be Goemon-san in working on paizuri-focused scenes, but his directing skills really carried much of Madonna’s flagship series moving forward. 👏
I hope Mei still has her charm in porn even after this new tittyfuck movie, as she’s turning 29 this October. 😊
