If you want an intense feeling of huge cock inside your vagina, this is the best.
Dildos are rarely big enough, so I use toothbrushes. I have a lot at home and I don't throw my old ones out. It's better to use just ordinary ones that have nicely shaped and round handles, and that has some rubber on.
Stick first one, then two toothbrushes in your vagina, increase the amount until there's no place left. Then you can focus on your clit. You can advance this using the electric toothbrush, so all the load vibrates good.
