OK I've been away for a while... but I'm back, and I've been looking around.

My idea of a perfect ass seems to vary widely from the consensus, or, to be less diplomatic,  I think most 'perfect ass' posts are  a waste of time.

So perfect ass = tight, firm, slim - no booty.

I like spanking with a white or red riding crop, so the crop should either lie across the small of the back in the cleft just above the buttocks, or nestle between the buttocks. There should be no need for clenching as, if the crop is between the buttocks the thighs are spread so I can kiss or caress the perineum or vulva, or stroke and finger the anus. Light stroking or application of a butt plug, ideally vibrating or heated, is popular.

The deal is 'no movement;' move and I spank, lightly. 'Tail in the air', with the pelvis resting on a bolster, rolled gym mat or something similar, works well. A nice enhancement is for the young lady to place her hands flat on the bed - any clenching of the fist and I press my erect penis against her anus -  no further - or part her lips with my cock so the glans is partly in.

Restraint is required by both of us. I aim to be hands free below her waist, apart from sparingly fingering her anus or vulva. Nose, lips, tongue, cock - fine - but no hands, no pushing the cock in... yet. 

I also spread my thighs as far apart as possible - less easy to just fuck her. When that time comes, and by then my cock and balls ache with desire and the glans is shiny with precum, then she often sets the pace.

Her position may change so she can tighten and release within, which drives me fucking wild. Then my hands have to be either on her rib cage or breasts or above or behind my head.

Its a good way to be edged.

Usually all this lasts for about 45 minutes; for a birthday I lasted 75 minutes and shot my load, unintentionally, into her ponytail. Bliss, though hard earned.

So my perfect asses are as follows:
