Oh yeah you can take more than that. It's gotta be thick too. I've got a few toys that will open you up like you want. I'd start training you with 10 inches and 2.5 thick. Warm you up with at least 3 fingers and plenty of lube, while teasing that clit ;)
theres a 10” dildo i have been wanting to buy for agessss super thick but its $70 :/ if u want to buy it for me i can make a custom vid for u when it arrives <3
