I have had some interesting experiences that aren't the normal meth or mdma together like you described, but I'd like to see if anyone is familiar with this. There is a really talented underground chemist in my home town of Orlando, Fl. who has mastered a substance everyone who tries agrees is best described as a super euphoric meth high, one that will literally blow you up & make you roll very similar to mdma but it isn't nearly as disorienting or intoxicating as mdma, you feel the super sensual & sexual euphoria, while maintaining more of your faculties & having a more realistic state of mind, at least as realistic as really potent, clean meth allows you to have if your an experienced meth user anyway. The sex is so incredible it's ridiculous. The drug can be taken pretty much anyway you can imagine, this chemist first suggested since he knew my history & what I like (oh GOD, did he Fuckin know what I like & nail it for me every time he tried so well I'm squirming in my seat right now as I imagine his ability to administer pleasure to parts of my body I never knew possible) So since he was familiar with how I like to get high & what really pops my tart if you will, he suggested I try it for the first time iv, & let him make my shot. Let me tell you quickly, I know quite a few people who pay him nicely just to make their shots, the man has a gift for knowing the perfect dosage of any substance for anyone after a few questions & a little history, especially for females. This is because he has a little girlfriend (actually I think their broken up now, I've waited years for this! Lol) who he tweaked various substances for almost exclusively day after day over years with the sole goal of bringing her tasty little body (she's a bad little bitch & I'm not usually attracted to my own gender) the most intense pleasure possible with a multitude of different drugs. So when he suggested he make my shot of his special "sex meth" as his little Princess called it, I immediately agreed & told him to hurry before she found out & put a stop to it since I knew it was a whole exclusive sexual high freak-nasty session they kept for themselves & I was quite certain shed consider this cheating & this girl was super obsessed with her man or "Daddy" as she called him & I soon learned why. About 5 seconds after I relaxed & leaned back after he gave me my shot, I felt a warm wave of euphoria washing over me, beginning at my shoulders, becoming hotter & rushing over me as it hit my titties, making my nipples hard enough to cut glass & causing me to unknowingly reach up & grab 2 handfuls of heaving, hot as hell breasts, instinctively pinching & twisting my nipples with a hard gasp, my breath totally taken away from me just like I was warned. I looked into his eyes as he smiled, then says all low & sexy "ok baby, now here comes the best part, do your best to relax completely, just keep looking in my eyes & don't fight what's coming, concentrate on how good you feel & I'm just gonna hold your hand & gently run my hand across your skin as that hot wave of pleasure moves on down your body." Then his smile gets even more mischievous than it was, I start to say "what is it?" but he puts his finger to my mouth & says "shhh. don't talk", just about the time I felt that intense wave of pleasure now pass my belly button, his hand moving with the wave across my skin, it slides down past the top of my panties, I realize I'm not breathing & my mouth is hanging wide open because the pins & needles sensation along with a surge of heat & wetness fill my pussy making me feel for a split second just like I'm about to per my pants, then realize as I'm still looking in his eyes as his expression becomes urgent & serious as he slowly & knowingly nods his head to confirm what was happening & that yes, he intended to not only soak my panties because now I realize they're soaked through, since I've now shoved a hand without any thought, just a reflex, right on top of my pussy & I'm squeezing her as she starts to contract, "oh my GOD, I'm CUMMING!" I blurt out as my eyes water & I'm now looking into my chemical lovers eyes completely starstruck & overwhelmed with the realization that this man made a substance so fucking sexy when he dosed me just right I was having a full-blown, full body orgasm within seconds after he slid it in my bloodstream, all while he led me to it & is riding it out with me in his eyes, I can see he's getting his own pleasure out of my climax, he knows he's the one who made it happen & was able to light up my body without taking any clothes off & only gently stroking my skin while holding my hand which I've nearly crushed as big as it is. I gasp again as the last major contraction rocks my entire body, then hear myself whimper out loud unintentionally, causing a smile of deep satisfaction to come across my future husband's face. After about 15 minutes of intense waves of hot pleasure washed over & over me, I got up & went in the living room where I laid on the couch & proceded to roll for the next few hours, variations in intensity & euphoria that succeeded in blowing me up very similar to some really strong e pills I had a few years back, but this lasted far longer & when it began easing up I went into a super happy, silly & loving state of mind that carried me through about a 11-12hr total high from start to finish. Now every time I think of that experience, my mind goes to the man who's talent made it happen & my panties honestly get damp while I wonder what all he can do in that lab of his. I'm going to see if he needs a new test subject since I heard little miss Princess got fired...
