My 30 (f) introduced me 28(M) to double vaginal penetration in the beginning of our relationship.
We have been together for a year now, love each other so dearly. I have never been so open with someone before and either have they. Our sex life has been the best ever. My gf has always been a good girl and has had a past of bad hookups and whatnot/ unfulfilling relationships. She is also shy when it comes to a lot of things. However, she is an absolute freak now that I think about it.
About 3 months into dating, my girlfriend introduced double vaginal penetration (dvp) with me in the form of stuffing her with a small vibrator and my cock while we were having sex. I remember fucking her and her asking if it would be okay to stuff her with her small vibrator too as I was pumping in and out of her. I am pretty average size (5.7 in x 4.9 in girth) so not too big and I remember her pussy being so tight with just that small vibrator inside her with my dick. I remember seeing her so turned on having her pussy getting filled up and stretched out. It was hard stuffing her with two things but it was so hot.
