G-spot orgasms are the bread and butter of female orgasms. This is where women are truly lucky to be women because they have that extra spot that allows them to have mind blowing orgasms.
The g-spot is located inside the vagina. If you take two fingers slip them slowly inside her and curl your two infers upwards deep inside her you will be able to feel a small spongy spot.
When she is aroused this increases in size and volume making it slightly easier to find.
