I can't believe this; 6 pages and not a single comment of how his semen went up her nose?!??! How much of a turn on is that?
Regarding the hands-free looking orgasm, I bet you dollars to donuts that buzzing sound in the background is a vibrator up the guy's ass. Never done it myself, but I've heard prostate massages will produce tons more semen.
On another discussion I just posted on, I could ejaculate similar to that by taking two tablespoons of lecithin granules daily. I had to stop because my wife thought it was simply too much to swallow and it had a tendency to get stuck in the back of her throat.
