After watching Tristan Taormino’s lucid, comprehensive presentation on the anatomical basics of G-spot stimulation and female ejaculation, most viewers will be eager beavers, so to speak, to try out the many tips, tricks and toys that she shares.

Taormino describes in detail how to coax the desired reaction using both fingers and toys—including specific recommendations on which items work best. She also covers which positions work best, and notes that each woman is highly individual in how she achieves an ejaculating orgasm, which can range from a geyser-like explosion to a less dramatic dribble.

Just as important, she also anticipates that not every student who hears her lecture is guaranteed to perform like a porn star. Different women ejaculate in very many different ways. The ones who shoot out a stream of liquid have strong PC muscle—yet some women with very tense PC muscles may not be able to ejaculate at all.

But those who can’t do can watch, and Taormino offers four demonstrations for our viewing pleasure. The chemistry is great in each scene, with plenty of time for chatter from both the women and the men. Dylan Ryan and Kylie Worthy find skillful, supportive partners in Mr. Marcus and Derrick Pierce respectively.

Petite, girlish Kaci Starr packs a punch in her scene with Anthony Rosano; the two have great chemistry, and they talk about experiences they’ve shared in the past. Starr cums repeatedly. As in all four of the scenes, there’s no male pop shot. Here it’s all about the squirting.

But when it comes to big O’s, they don’t get much bigger than Jada Fire's. The erstwhile Squirtwoman teams up with the always-game Christian XXX, and she erupts like Old Faithful … but with greater frequency. “I do have a favorite position—it’s reverse cow—because then I can get it all out,” Fire explains. And get it out she does. It’ll leave those women with tight PC muscles feeling quite envious.
