Ok, I may seem young, but trust me this is ingenious! I have a few ways:
1 ~ THE TOOTHBRUSH TECHNIQUE! Any electric toothbrush will do, but you can use the end with the bristles and not even actually put it inside of you! You can just hold it with your hands and squeeze every muscle of your body, it takes a minute but it is TOTALLY worth it! **You can use the same toothbrush as normal, just make sure none of the part that you can't remove and change doesn't get wet! Buy a few replacement heads and it is great!**
2 ~ I have this liquid eyeliner that I bought at Sally Beauty Supply and it has a kind of pointed tip, I put it all the way inside me and pump or just leave it, it is great!
3 ~ Put the sprayer part of some perfume or something inside you and just pump it, this won't give you an orgasm normally, but it feels wonderful!
4 ~ This one is kinda nasty, but get some old Trophy for softball, basketball, baseball, volleyball, soccer or bowling or something, (it has to have an actual mini-version of the ball on it) and just stick that inside you and pump, it goes in smoothly an really far, this is so much fun to do especially with a girlfriend there! (No I am not a lezbo; it's just fun to compare and scream together during orgasms!)
~ Now I have to go jill off because this made me so freakin' horny I could explode!~
~*Hope this helped you! Keep them coming ladies!*~
