Inc advice from a straight guy who has no idea what he’s talking about. *ahem* Using the vid above as a guide, have subject lay back, possibly in a recliner, or where they can completely relax and spread thighs nice and wide. Place both hands on tops of spread thighs as they aren’t needed at all. Proceed to kiss all around cock and balls without touching, getting to know it’s throbbing warmth against your cheeks. After a few minutes, start by worshipping said balls, with lots of kisses exclusively on the underside of the shaft in a fluid bottom to top motion. Lots and lots of deep pressing frenchkisses. Gently administer a full, sloppy as possible teabagging, treating said balls as if they’re the divine orbs of the universe. Clean and love every inch of them. Time for the tongue. Lift balls with nose and give a thorough, rough, wet perineum gland licking (at which point subject may start to grind. Completely allow this.) Get tongue as wet as possible and again, focus primarily on keeping pressured licking to the sensitive underside, from the base of the balls all the way up to the urethra, but gradually work saliva around to the sides as well. After a while, place middle and index fingers in mouth and get them wet til they’re practically dripping with saliva, then, using just the fingertips, begin rhythmically prodding the anus in circular fashion, not at all pushing in, but massaging, relaxing muscles. Once more begin kissing allll over said cock, including balls. After some minutes, take free hand and place it on target’s stomach, then start verrrry slowly pressing fingertips up the rectum. With enough massaging and saliva, there should be next to no friction, but proceed slowly enough to that target accepts entry completely at their own pace. Keep gently sliding in fingers til down to the knuckles, letting target clench and squeeze as much as they want before achieving maximum depth and stopping. Gently begin directly massaging, keeping focused pressure on the prostate. Open mouth. Begin gradually sucking downwards. Don’t be greedy. With each progressive suck, go lower and lower, until you can hopefully hilt target. During this, secrete as much saliva as possible (saliva is the absolute key) Begin sucking, variating between suction and lots and lots of licking veins and so forth. Begin putting significantly increased pressure of fingertips on prostate, rubbing round and round. Sporatically deepthroat and hold, letting subject thrust as firmly down your throat as they like. Keep this up until you feel subject begin to throb and pulsate. Preferences vary, but I would say give one final deepthroat and hold in place til they release fully, finish ejaculating. Bring lips to about the midpoint of the shaft (assuming no condom) and gently suck to extract out what’s ever left in the urethra. Remove lips and give a very tender loving kissing all over the cock as appreciation. And walla.
