The feeling of pumping should be very pleasant. Initially, clitoris swelling will occur, followed by the engorgement of the entire vagina. After a few minutes, you should feel aroused after the clit hardens. This will probably make your partner pretty desperate to get ahold of you.
The tingling sensation gets even better when the air is let out. It’s gonna be a blast! Consider it a fusion of visual stimulation and being sucked on by someone else. With a vibrating toy, you can have an orgasm without having a sexual encounter.
