A form of manual stimulation that involves inserting two fingers into the vagina. This is slightly different than the traditional finger bang. Instead of just blindly slamming fingers into the fuck hole, the two fingers MUST specifically stimulate the female G-spot. Said stimulation will induce a tsumani-like female ejaculation.
This technique can be used anywhere, but for best results, it should take place in the back of the N-Judah. Bonus if she is already a squirter.
I hear Denise is a serious squirter. Imma try the Two Finger Tsunami Cum on her next time we ride the N-Judah. The back seat will be flooded with vag juice by the time I'm done
