I come home from partying with my co-workers.  I ate way too much food and I have bad gas.  Very bad gas.  I've been holding my farts in all night and I can’t wait to get home to sit on the couch and gulp my brains out.   I finally arrive home in my tight jeans, kick off my shoes and lay back to sit on the couch.  My step-son and his 3 friends (all of which think their step-moms have the most musical multitoned farts) are all laying in the living room in rest bags.  Its after midnight and they’re just about to go to rest.   I say hello to them and sit on the couch.  I start ripping out the farts, low, deep, and bubbly on the couch during conversation.   Getting interrupted midway through my sentences to fart, then finish my sentence.  After a few minutes they all start to rest, yet I just got started!  The farts get progressively longer, gulpier, and bubblier and I decide to give them all a show they’ll never forget.    I know they all have fart fetishes because my step-son has mentioned to me how they fancy their own step-moms farts yet I know there’s no competition given my capabilities.  What a great opportunity to prove my throne. As I continue to belt the farts into the seat cushion, I notice how each of their dicks start getting harder and harder.  Before I know it, they all start slowly jerking off under their rest bags.  The longer and bubblier the farts become, the harder they all start jerking.  I treat it as a game making each one to cum.  My goal is for each one to cum while using my abilities to produce the longest, gulpiest, bubbliest, most multi-toned obnoxiously complex and deep musically bubble farts.   The sounds are just too sexy for them to contain, and one by one, they all start busing nuts listening to me fart obnoxiously into the seat cushion.   I managed to get 3 out of 4 to cum within 15 minutes, yet the last one hasn’t cum yet.  I clearly see him jerking vigorously harder with each fart I rip.   The first 3 start jerking off again ready to cum a 2nd time, yet #4 still hasn’t cum yet!  This is when I really start ripping the most violently bubble farts as I am determined to make him cum.  I eventually let out some outrageously long, ultra musical and multitoned Gulpy farts and #4 finally busts his nut.   I made them all cum… This was a custom video and I sit on the phone for the whole video, so is black screen while you listen to my bubbly muffled farts.
