The Fuck Flask (by Pipedream/PDX Brands) stroker is realistic, tight, squishy, and discreet (looks like a water bottle from the outside). Let’s check it out.
Unboxing & Inspection
This stroker comes in a pretty obvious box, but we’ve removed the original packaging and/or Extra Discreetly Packaged these Fuck Flasks for many customers who need completely discreet delivery.
Inside, the stroker sleeve comes packaged upside down, so you need to remove it and re-insert it with the orifice facing up. If you try using it without doing this, the sleeve will slide away from you into the back of the water bottle. (Also, the rim at the base would be restrictive and annoying…)

The body of the bottle is hard plastic with a chrome-like accent, and it has a heavy-duty plastic lid and plastic base. The top and bottom unscrew, and oddly enough, the bottle could actually function as a mostly-leakproof water bottle in a pinch.
The Fuck Flask’s sleeve is pleasantly realistic; more so than I expected. The material feels a bit sticky/tacky and is marketed as “FantaFlesh,” but Pipedream clarified that the material is a blend of ABS plastic, TPE, polypropylene, and silicone. They recommend only using water-based lube with these.
The sleeve has a sweet array of ribs and bumps inside, and it fits inside the water bottle with room along the sides to expand as you fill it (more on this later). It’s got holes in the end of the stroker which make it easier to clean and dry. (Side note: my Lovense Solace Pro sleeve doesn’t have holes in it, and I left it stretched out to dry, forgot it, and the material started splitting in places where it was stretched.)
The lid has a few functional features: the flip “straw” can control the suction effect during use. Open it to decrease suction and close it to increase. The loop handle gives you something to hold onto or tie down if attempting to use handsfree.
The Fuck Flask has a 1-year warranty, but you need to register your item and include proof of purchase (like a HappyBed order confirmation) before starting a warranty claim.
My Experience Using the Fuck Flask
This stroker is interesting in that it’s totally unsuspecting in its bottle form but unscrew its base, and the revealed pussy is surprisingly realistic.
The sleeve material feels comparable to a higher end stroker like a Kiiroo Feel Stars. It feels a bit springier than the silky soft Tenga TPE/elastomer. The sleeve fits inside the bottle with enough room to stretch as I plunge inside; it’s just tight enough yet doesn’t feel as restrictive as some of the tighter “contained” strokers. In comparison, particularly the yellow and pink Tenga Puffys, which seem a bit more restricted by their outer housings. I’d definitely categorize this as a one-size-fits-most stroker.
Insertable depth is advertised as 7″ which accounts for about 6″ of the sleeve contained in the bottle plus about 1″ of additional depth where the vulva/orifice puffs out beyond the rim. There is about 1″ of unused space on the lid end, but this flexes during use.
I experimented with the flip lid, and it makes a noticeable difference in the amount of suction as I draw in and out of the stroker. I appreciate the simplicity of that concept; just flip the lid – no buttons, unscrewing, none of that business.
Cleaning the sleeve is a bit easier than other closed-ended products, given the holes in the base of the sleeve. I also found that the Fuck Flask fits reasonably well in the Fleshlight Air automatic dryer. I just placed it face down with the Fleshlight Go attachment ring. It dried completely on the lowest/first setting!
Final Thoughts
We haven’t found many strokers that are as discreet as the Fuck Flask (the PDX Shampoo Bottle strokers come to mind, but they’ve got suggestive verbiage on the outside of the bottle, so definitely not fully discreet). While I’d love for the sleeve to be silicone, I can live with a TPE/silicone blend sleeve, especially at this price point and with the added element of secrecy. It really is an exceedingly boring water bottle from the outside but a pleasantly realistic and tight pussy on the inside!
