Chastity and orgasm denial discussion

Ah happy days my vanilla GF is getting into locking me up, she says it’s exiting and a thrill doing the teasing and denying.. When I before asked her if I had the largest cocks of all the guys she’s been with, she said yes. She says I’m waay to big for her already, but I know she is lying just to be nice.. Now she finally agreed to try out a cock sleeve to tease me, and I assured her that if she came fucking a bigger “dick” it wouldn’t hurt me, only in a good way;) just ordered the 10” clear mighty cock sleeve. Can’t wait to fuck her with that!! I know she will appreciate it
