I'm going to have to remember that trick.
Well, I'm also going to have to get a fridge/freezer for my room: I don't know how my rather prudish roomie would feel about trays of cum in the freezer.
When I have had three or four loads in me, I like to save them for the devil's dick. I used a liquor glass and popsicle stick and keep them in the freezer. If I'm going to a gangbang, I insert one and let it melt so it becomes a great lube. Nothing like enjoying a load more than once.
I guess the size of the prescription bottle depends on the gap of your hole? I mean I know some guys who could probably have mason jars of sperm frozen, and still take them. lol
