by TrevallyJack on Mar 9, 2020
Interracial Love

He perked up and leaned back on a desk. His now rock-hard cock pointing straight at me. Did it get even bigger? I gulped. "Jesus that's big," I blurted out. I was standing but the head of the cock was already square between my breasts. "Come on Ms. Siu," Tim moaned in mock agony. "It hurts, it hurts!" Well, no turning back now. Two days earlier Eli...

BDSM

My wife is very kinky; I'll say that right now. She likes dominating me and teasing my body until I scream for release. She says it's for research... her own. Since she calls it research she institutes 'controls', basically the controls are me tied up so I can't touch her or myself. She made me set up a table in the basement with padded straps for my wrists...

by Ashesh9 on Sep 17, 2017
BDSM

My wife of 15 years, mother of my two kids, came up to me and abruptly, violently and unexpectedly, kneed me in my groin, adroitly smashing my testicles, like an experienced street walker who handles drunkard johns every night.

My Aggressively Horny Buttocks!

by Ashesh9 on Sep 14, 2017
How To

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 horn...
