She said it was great. I'm not into inflicting pain so I never pushed it. Just some gentle pressure as it slowly slid over each bead. I so enjoyed her lifting her hips up in anticipation of each bead, presenting her ass as a perfect offering. Then a fun little pop, pop, pop on the way out that made her giggle.
Really, I was just helping her expand the horizons of her enjoyment as she requested. I felt complimented that she let me be the one to play with her while she tried something new. I left her with the toys and lube so she could practice/play on her own. But I did offer to check out her progress on occasion.
As to the scale of the toy, it is about eight inches from the tip to the base of the "fifth level". The last bead looked like it might have been a bit under an inch and a half (1.5") in diameter.
I know my stories aren't as epic as some of the hardlegs amongst us, but I wanted to share this, and solicit some input additional ideas she might enjoy as she goes down this new path.
