This one time I was going to work out with a friend, and he’s always likes to try to brag about how big of a dick he has obnoxiously and stuff so I wanted to knock him down a bit so I enhanced my bulge a bit to get him to shut-up as I knew we’d both be changing in the locker room, heh.
I used used ace bandage wrap I use for multiple PE uses, I pulled my flaccid out and wrapped from the glands to the base basically keeping it fully elongated and went around some more to create some girth. Then I had some silicone anti-fluid cones from a vachanger so I topped my head off with that to keep my glands from sucking inside the wrap and it produced a realistic looking mushroom tip under the briefs. Overall it produces a really realistic big cock under your briefs, as you have the correct shape, tip and movement. You just have to make sure the wrap doesn’t produce any weird seams through your briefs too.
You could probably come up with something similar for the tip, I think the big trick that makes this look so good is that you get the glands bump which makes the bulge look realistic, not a shapeless sock or whatever. Plus, It allows your dick a bit of realistic swing as it’s still based on your real cock. I’ve used this before as a makeshift anti-turtle ADS and it actually provides a nice bit of elongation if you wrap it right.
