from 8/10/21: i feel like i need to explain why i uh,, sound kinda gassy when i cum,, if i take out my dildo at a certain angle, air comes in and if i spread my butt open, it will gape. the air also seems to keep my second ring open so i can fuck it a little faster without it hurting (it closes right up otherwise). then i push out when i cum, which also pushes the air out. (i'm still not completely sure i'm cumming but it feels great lol)
