so ive done 3 sessions, 2 with Vivienne Rose, and 1 with Kass before she sadly passed (RIP)
They were both very nice and went at whatever pace you wanted, as to not get yourself hurt while they're on you. I realized I much preferred them sitting on my lap and laying on top of me, compared to facesitting. The combined sensation of not being able to breathe and the musky smell was a bit much for me to really enjoy it properly (i also have a very sensitive sense of smell lol)
I surprised myself by not cumming at all during the sessions, as I feared I would do so. Vivienne actually told me she had a client who immediately jizzed himself right as she sat on him lol
It's definitely worth the money, I will just note that there was a noticeable difference in their weight, as Kass was like an extra 200 pounds. I wasn't able to endure chestsitting for too long with her like I was able to with Vivienne! So keep that in mind when booking a model, I know the bigger the better but it's best to start with someone in the 300-400lb range if it's your first time lol
