Everyone Needs to try this at Least Once

Color: BlackVerified Purchase My wife and I love this. I'm ~7" and its the perfect length. While we have a great sex life and I can get her off with just myself easily, this takes the intensity to an entire new level. The added girth requires a liberal amount of lubricant and patience but there's nothing quite like going at full tilt with this thing. The ridges on the inside feel amazing for me too. We can't recommend it enough. Pro tip: I've found that I can change how long I can last by adjusting the amount of lube used on the inside. I can go indefinitely with none inside and it hardly takes me any time at all when there's a lot. Experiment with different amounts to find the sweet spot.

With this toy, and with most Sex Things, lube is your best friend. Lube is your friend with benefits. Lube is your wife. ♥- Simpli Comedians

Amazing product, it is called the fat boy thin but i assure u it is not thin at all. It feels great, fits great and pleases the woman like nothing i have experienced before, i mean she was reaching orgasms over and over again. This is a must have product. I am 7inches in length and a normal girth, this extender i give an AAAAAA++++++++ it is just right, not to big where it feels unreal but def big enough to make a lasting impression. Thank you perfect fit, i will definitely be back and will recommend your products to all my friends

This is an awesome product for both my wife and I. She enjoys the girth of it and I enjoy the fact she is having a better sex life. The only thing is I (she) wishes in would have an extension of about 1 inch with a head. It feels great on my cock during intercourse. A++

Wife Loved It And It Helped Tremendously with My ED

Thank you for changing my life, sex life that is. I'm 61 and suffer from ED brought on by serotonin interrupter medication. I'm 5'5" x 5" naturally. I had to stuff a few cotton balls in the tip, but this thing is fucking amazing. Most men think that a woman wants a big long cock. No true my friends. Girth is what they want and Fat Boys give it to them. Wife doesn't like dildos because they are hard. We tossed them all. I showed her this, but it on and put it in and all she said was, "that feels just like you". I love it. I will make one suggestion. When using a water based lube, put some in a bottle and mix some spring water in it. Water based lube does make it drag. I use a small syringe and squirt some in my wife's vagina and lube he outside and away we go. We went for over 40 minutes and she didn't complain once. Doggy style is not a reality. Also, I hollered out when I shot my load. After washing it I rolled a wash cloth up and rolled it onto to it. My wife wants to go again tomorrow only this time she wants to sit on it. Thank You Perfect Fit.

The Fat boy line is the best

I have tried the entire fat boy line and must say it is the best. The standard fat boy was too large for my wife the sport was to tight for me but all models had benefits and were enjoyable but for me the thin large was the best it has become a great part of foreplay and feels great for both parties.

Really great

I'm a little smaller than average, and my wife and I were looking for something so she could feel me. Basically it is great, but too long (there is a lot of space at the tip). The space at the tip can make penetration difficult. We probably should have gotten the "sport" model (which we've ordered!). It feels great for both me and her, and we're looking forward to trying the sport model which should fit me better--shorter and hopefully a bit more intense.

Sometimes, it takes a couple different products to find the toy that works best for you. Best case, you end up with a collection of toys you use often, worst case, you end up with a collection of toys your friends will envy. ♥- Simpli Comedians

I use this as JO sleeve

I use this as a JO sleeve. It's the best I've used so far. Very impressed. Love the little bumps and ridges on the inside. The ball loop is a brilliant addition. It may be a little short for me but not a problem at all.

Using it as a JO sleeve is also amazing practice for partner play. But it's obviously fun enough on its own. ;) ♥- Simpli Comedians

The best toy I have ever

The best toy I've ever bought. The feel of this when wrapped around me is amazing to say the least. It's just as good, dare I say it, or better than the real thing!!!

Pretty cool

I've worn this 2x and my wife likes it over another extender we have, but she said she doesn't care for the time it takes to put on.

Sounds like your wife is wishing for a little less foreplay and a little more... threeplay. ♥- Simpli Comedians

Great Fit

Have had the "sport" version of the Fat Boy, but felt I needed one that was sized a bit longer. This is a better size for me, as I'm average in length/girth. Combined with the Armour Lock(I highly recommend this product), the base of the Fat Boy stays even more securely wrapped around your balls. You obtain/maintain an incredible erection, and my wife loves the increase in girth(as do most women). The orgasms for both of us are incredible. With that said, I now know that we will want to try the Original Fat Boy (8.5" long) to enjoy the desired sensation of even MORE girth. Thanks PF!

You know the sleeve is good when it's motivating you to get more. After all, you'd never wanna be caught without one. ♥- Simpli Comedians
