Big Daddy Hollow Strap On
The Big Daddy goes bigger, thicker, and more hard-core than the competition. You don’t really get a real feel for how BIG this strap on is until you see it in person (or in the video below for a better idea).
The extra-large strap on dong calls for a more heavy-duty harness which comes with thick elastic straps, and a leather holster.
The included Waist can stretch up to 48 inches with room to spare. The included Hollow dong measures 8.25 inches with an insertable length of 10.5 inches and a width of 2 inches. The hollow cavity measures 5.5 inches with an inner diameter of 1.25 inches.

MQ Reader Review
Deep Dicking – Damn! This sucker is huge. I shocked my girlfriend last week. Big Daddy is ten inches and nearly two inches in width. I slid this sucker in her so deep she nearly creamed when I hit her cervix. She can’t complain this fills her up and makes her happy.

The unique strap on system features two heavy-duty, nylon shoulder straps that distribute the weight of this massive hollow dildo comfortably.
Like other harnesses, the metal o-ring system holds the dong in place. This might be the best holow strap on dong thanks to its realness and size. This massive dildo comes in both 10 and 12 inches making it one of the best strap ons we have tested.
MQ Reader Review:
When he got this for me it has added back an old flame in our sexual life. The first time I sat on it and had an orgasm, WOW. I felt like I needed to be scraped off the ceiling. We have now experimented with it in different positions and I know I love it, and I have seen that old smile on my hubby’s face when I climax.

Silicone Strap Ons
Most hollow stap-ons are made from hard PVC as it is an ideal material thanks to its rigidity and durability for the hollow design. Although, there are a few silicone options available. This is great if you are looking got a higher-quality, non-alergetic option, made form body safe materials.
Fetish Fantasy Extreme 7 Inch Silicone Hollow Strap On
It’s hard to describe just how realistic and veiny this cock really is. The Fetish Fantasy is perfectly shaped, sized, and down right sexy to look at. The hard silicone build is rigid and smooth. This cock also has a unique star on harness with adjustable bands that hold a very low profile.
However, the compact front means that it is less effective at distributing pressure, especially if you plan on intense, high thrust sessions (check our next option on the list). Overall though, it is one of the best traditional silicone male strap ons you can buy.

Due to Type 2 diabetes my husband could not get an erection. Certainly he could give me oral sex and use a dildo on me but what I wanted is the feel of being thrusted . I ordered a Fetish Fantasy Inflatable Vibrating Hollow Strap-On . It feels great now to have my pussy thrusted once again by my husband. Some days he takes me 3 or 4 times and each session can last for over an hour
