soulmates_93436I find that taking hits of 'poppers' definitely helps my sphincter to relax as I'm receiving a very large dick (8" plus) in my ass. I get the 'euphoric high' that allows me to push back to take more of his dick inside.
Or, when my wife and I are sucking (sharing) a nice big Black dick, she'll take over when the guy indicates that he's about to blow his wad in order to take a 'lung full of poppers', then "take over to receive his full hot load"...
Yummmm... :-P
