O no I fucked up again hahahahahhaah, shit.
NO ya dont need two pins, just one for the CONSTRICTED version I DO.
Simply get erect full, clamp of ---- ya know the rest etc etc .... slap ya cock onto the table/desk/flat surface LEVEL with ya hips so ya not at a funny angle...than get ya pin and press down, begin the session.
Do 30 minutes of hard/medium pressing rolls, mix and match also with how deep ya push and whatever comes to mind, like slidein ya cock from under pin while pressin dowmn on it......I am telling ya THIS SHIT WORKS GREAT, but it wont be for everyone, it can be painful at times [not much] as you keep pressin the penis with the pin ... but I can gurantee ya will feel it afterwards, like a good session at the gym.....also beware ya wont get erect proper for the WHOLE day/night than, the penis will shrink abit ... its normal, but the next day and day after that it will keep pumped up .... will get erections more often, harder also .... you will feel and notice the size change....I still am after nearly 7 days of one session.
Okay,
anyway .... thats how I do it, ya could try ATS version with two pins but I dunno how that will turn out, maybe try it and see?
goodluck
cya soon
