1-minute loop, 4 hours later: one of the hardest erections ever, total control, heightened sensitivity

I listened to a 1-minute loop at about 4pm and forgot about it — no sex drive, no sexual thoughts, nothing. At about 8pm, out of the blue she initiated, and I got what's probably one of the hardest, biggest erections ever — absolute and effortless control of my sexual energy too. My sensitivity was heightened, but not in the way that makes it hard to control ejaculation — in a way where I was able to feel in my penis every little detail as if it was a fingertip. She got as many orgasms as she wanted and I kept my energy within.
