I repeatedly warned him, “if you keep vigorously probing my backside with your tongue, you’re bound to strike oil.” True to form, after I had ground my pussy and ass into his face for a solid half hour, his persistent tongue-thrusting finally paid off. Sure enough, I captured the exact moment my excrement emerged from my anus, landing squarely on his tongue. My challenge to you is to resist your orgasm until that precise instant. Good luck.
