The shoulders and leg holster is made of pillows so that way it is comfy while trying to hold don't worry the straps are adjustable to whatever size you are needing. As a BBW with chunky thighs and my partner is not skinny this fit as a snug.
The Sling allowed me to sit on him while he sits in a chair and allowed me to ride him without the fears of falling off and getting hurt. The sling takes sex to a whole new level and if you are brave enough you should try it. It uses all their upper body strength but not in a bad way. It's no different from them hanging on to you and holding you. This is just a safety measure and truthfully I enjoy it.
I could get into any position I could and just get all the pleasure from it and it was just overall a great experience. I never got one of these since my partner has issues with his back, ankle and could hardly pick me up but with this he had no issues with anything and the pillows made it so no one would get hurt in the process.
Don't worry this works for everyone who is willing to try it.
