This is an esoteric yogic technique: centuries old.
*
I jackknife my ass into my sub's vagina and thrust into her yoni/pussy repeatedly as the two-petalled Mooladhara chakra or male prostate gland blossoms at the impact of my horny buttocks into willing feminine warmth, vulnerability and submissiveness.
I get the same excitement in this action that a horny submissive male gets by being ass-fucked by a strap on-wearing Mistress but in this case my buttocks and prostate get the full treatment without a humiliating enema, spanking or sodomizing dominatrix being on Top & the male being Bottom!
On the contrary, I am Master, she is sub!!
As I continue thrusting my arse into my slave girl, inevitably I end up getting an erection & I rapidly shift position.
I signal her to turn around, hold onto bed, chair, table or other furniture bend over and present her nether cheeks to my Lingam/phallus!
My penile tip just makes contact with her moist vaginal lip! I inhale a deep breath and squeeze the Svadisthana chakra[ the muscle which controls,cuts off or allows the flow of urine is the Svadisthana chakra] and feel indefinitely delayed orgasmic-bliss. I do not ejaculate but copious quantities of clear, viscous fluid/pre-cum leaks out continuously while Kundalini Shakti [ which is the Semen transformed/metamorphed shoots up my spinal cord thru' the super-sensuous shushumna nadi/channel to the center of my head where the thousand-petalled Sahasrara chakra blooms/blossoms, flooding me with emotional/yogic/mental/aesthetic bliss!!
I spank my slave-girl's buttocks in joy/exhilaration not viciously but enough to smart/tingle/stimulate and silently chant' Jai Sri Lingam!'[ or Victory Lord Phallus!].
