Theres the finger way, that someone pointed out before, the using your cock way, extreamly hard to do correctly, or the using a dildo way, which gets my girl squirtin in less then 30 seconds, every 30 seconds.
Simply lube up dildo, insert when she is laying on her back, pillow behind head.simply angle the tip of the dildo into the roof of her vag(tword her belly) and fuck her hard. itll slam her gspot every thrust. when she gets so tight it feels like you cant keep screwingher with it cause shes pushing out so hard pull out the dildo. shell squirt everywhere. Dont wait too long before using the dildo again though, like two seconds at max, you wanna keep fucking her while shes squirting, its just a real big turnon to see her squirt fifteen feet at her climax. Oh also, i forgot, get a bullet and play with her clit with it at the same time you fuck her, and talk dirty. The look on her face. When I see that look, I just want to take a picture, its so cute and sexy and makes me feel like a sex deity all at the same time.
Venus, you gotta hit your gspot with relative force to build up enough liquade inside to squirt it out. and you cant miss a beat. miss one thrust, and its back to step one.
