Well, certainly the quickest way to have a reliable income. The safest one is probably the cafe, when you can work as a chef and make "creambuns". Not certain if this is possible as a male character but as a female with normal "milk producing capabilities" you can make 350+£ per shift without raising suspicion once the cafe has reached its "final form"
Problem just is, it takes quite some time to develope the cafe to this point.
I guess you are in for a surprise here. Males are much better in the cafe. Futas even more so. (Ordinary males can also give milk!)
You've gathered 917.2 mL of semen, 62.9 mL of vaginal fluid, and 266.4 mL of milk.
42 buns for £1k9. Depending on fullness and arousal I make 35…55 buns per session.
If "orgasm addict" still has an effect on goo production, this will soon be even more.
Yeah, I know that looks pretty imba. You can drain your balls in a couple of session and make >£9k from semen alone. But you can never drain you boobies.
The cafe is by far the best cash cow so far (pun intended^^), but you are right, it takes an awful amount of time to get there.
