[100Proof]

As a lucky asshole whose had a girl for more than 5 years who is not only interested in BE but a willing test subject, the only advice I can give any guy with the same dumb luck is to a) be careful and b) be persistent.

The first piece of advice is more important than you might think. A lot of the herbal supplements and cremes are loaded with different forms of estrogen and estrogen derivatives. While they very well may give your girl a temporary boost in the bust department (for the same reasons that birth control does in some women), taken in excess for long periods of time can significantly increase cancer risk particularly in women predisposed to breast cancer. They are also known to eff with your metabolism and cause ladies to put on weight faster and more easily than they normally would. Do the research, don't take more than the recommended dosage and go in cycles.

As for persistence, I can only give you my anecdotal evidence. My girl has gone from a DD when I met her to an H after years of experimenting with herbal supplements, inducing lactation and different forms of birth control. No pregnancy involved. She did gain a significant amount of weight at one point (30-40 lbs), but a lot of that had to do with one particular nasty birth control pill that did not agree with her. She has since lost most of that and kept her prized treasures.

Obviously a lot of this has to do with genetics and if your girl is flat as a board, she's likely not pre-disposed to see any significant results from tinkering with her body chemistry. That said, you can still have a lot of fun experimenting and there's a lot of different things to try:

- Inducing lactation using a breast pump and domperidone (anti-nausea drug with amusing, milky side effects). Most effective method I've found. It takes a couple of weeks before you start seeing results, but nothing is quite as effective as booting up the dairy factory. Granted, you have to be pretty religious about pumping and taking the drugs, but as long as you're not averse to the side effects (soreness, milkiness), it's the most natural method and a great indicator of a woman's "potential".

- Using the aforementioned fenugreek combined with other herbal remedies... these cocktails don't generally show any significant long-term results, but if your girl is one of the lucky ones whose body reacts to the hormones found in these herbs, you may be able to see some results.

- Experimenting with various birth control pills. While the majority of BC these days is pretty low on the types of hormones that provide the results you're looking for, if you experiment with enough of them, you're likely to find one your girl's body reacts to.

- For a slightly kinkier (read: much more painful) method, you can inject saline directly in to the breast. It will dissolve in to the blood stream after a few hours, but it's tough to beat for immediate results. Please keep in mind this is very dangerous if you don't know what you're doing and inadvisable unless your girl likes/doesn't mind pain and you're not afraid to make an awkward call to the emergency room if you screw it up.

- Obviously there's your fantasy-related stuff... push-ups, water bras, home-made BE contraptions. No actual results, but if your girl is down for a little roleplay/fantasy dirty talk, it's all of the great sex with none of the potential downsides.

The important part is to do your research, be safe and HAVE FUN.
