I remember the first time I discovered the pleasure of spanking my pussy while masturbating. I was laying back on my bed, naked, legs spread wide, my nipples and pussy worked up and swollen.
I had one hand spreading my pussy lips wide apart, while the other vigorously rubbed my clit until I got to the edge of cumming. Then I'd stop, let go of my spread lips, and slid my fingers down to gently rub the outside and inner edges of my vagina, making bigger and bigger circles to end up rubbing my lips and inner thighs.
I arched my back, grinding my anus into the bedsheets, rubbing, rubbing, rubbing my pussy. I reached back down with my other hand and spread my lips open wide again. When I got to the point of orgasm, I stopped rubbing, and smacked my spread wide open clit and vagina hard, then lightly rubbed away the tingle. Back to the edge, rubbing all the slimy wet around, then hitting it even harder.
I had to wait to touch my vagina again for a few seconds after that one to avoid coming, clenching my cunt muscles and feeling the tingles. Light caressing again, backing off, caressing, and then smack, then resting, then slapping it, hard, over and over, bringing my pussy to orgasm, feeling the surges and contractions of the muscles, the tingling all the way up my clit shaft. I rubbed away the remaining desire and went to clean up.
