Mine is meth and oxycontin, and even better if I'd been up for a day. I went through a phase where they were so good and intense and Long. They were so long, I decided to record myself so I could find out how long they lasted. And they were so intense that I gave my husband specific instructions NOT to stop until I said to, even if he thought I was done, or I'd kill him lol. Once it was so intense, after screaming and cussing and moaning, all I could do was die laughing. The realist, deepest laugh ever. And most of those times, i literally thought i was gonna black out before it was all over with. Good stuff!
