tick together tightly, one by one,

Shrink and shrink, tighten and release,

A small blush appeared on the skin of the two,

involuntarily twisting,

Many tiny beads of sweat ooze out,

The limbs twitch and stiffen comfortably,

All the way to the numbness to the legs,

spread to the back,

The tingling, cramping feeling of an electric shock,

wave after wave like the tide,

swept the whole body along the filament blood vessels,

wave after wave,

At this time, the brain was dizzy to a state of ethereal trance,

Light and fluttering like clouds and fog in a fairyland,

The whole person was melted into cloud after cloud,

After 1 stick of incense,

The two of them trembled slightly,

The hands around the back are getting tighter and tighter,

The muscles under the lower abdomen contract and contract,

The whole body twists up and down involuntarily, left and right,

The ever-flowing water droplets,

From the depths of the valley and steppe,
