Tama Handling

>How do I Tama a Tama?

Well, you stroke its belly first to pacify it. Then, when it's calm, and rolls over, you start making these low toneless throaty purr-like noises to it. This should get its attention and make it start curling down to sniff at you. At this point it'll be wondering why you don't look like a Tama. Just stay calm and keep petting its belly. Eventually, it should lay back down again and relax. This is where you can do a strange little trick.
Give it a strong rub down the midline split of its ventral lower abdominal scutes, towards the slit. It will immediately start squirming in confusion, but here's what you have to do: Immediately after you give it the ventral infraabdominal rub, lay down on top of its belly, hugging as much as your body to its underside as you can. (This will make it reflexively calm down so as not to hurt you, since it now sees you as either another Tama friend, or a Tama youngling.)
Keep on hugging its underside close as you rub right above its slit. After a few seconds, it should evert its member. Don't touch it at this point, you'll just unnerve it: keep rubbing right above its slit instead. It will get more and more erect, and eventually start squirming slightly.
Keep on cooing to it, hugging it closely and rubbing the erogenous zone. The longer you go, the surer you'll be he's begun to think of you as something sexual.
He'll drip a lot (a LOT if you keep on doing it for a long time) and probably get a bit frisky and raunchy after a while (the abdominal clutch reflex should keep him from bucking and squirming too much, though).
He'll remember you for quite a while after this, especially if you get him off (which you should).

Also keep in mind: that slight citrus smell can be a bitch to get out of clothes, pleasant as it is. (Experienced handlers will immedietaly know it's the"lewd-Tama-smell" so take care.)
A solution of water, a drop of detergent, some baking soda and hydrogen peroxide should take care of it.

>And what if it's female and has breasts?

Oh, in that case, you need to start a bit different, depending on whether she's in season or not.
If she's in season, and already accustomed to you and letting you close, I suppose there's not much to it. Just be careful not to hurt her, and remember the rule about estrous misutzune: letting her nibble and lick is fine, but push her snout away or she'll start nibbling harder and harder. Repeat as necessary. (Too bad we humans don't have scales, huh? Heh)
If she's in season and not familiar/safe with you, you can do the following: Wait until she's eating or sleeping, then move up behind her. Quickly and assertively (wear protective gear, just in case--they can be feisty) get in next to the base of her tail, then do the "breeder's grip"; grab with the area from your index finger tip to your thumbtip, firmly, around the base of her tail. It's important you apply a firm constant pressure here.
She'll probably roar and hiss, trying to reach back andsnap at you, as well as stomp/reposition her legs awkwardly and confusedly (wear protective boots, or be careful).
Just stay there for a little while (it might be hard since their tails are pretty muscular and our finger muscles aint) and she should start moving slower (though still hissing and holding her jaws parted). She should be doing this slow waving motions with her head while hissing. When she does, you can start hissing back (some say you could "rake" sort of at the ground at this point too, but I don't think it does anything). Just be loud and ..I dunno, bossy or assertive I guess.
You can let up of her tailbase at this point and see if she stays calm. If she starts up thrashing, just squeeze down again and rub a little.
Eventually she'll start tossing her neck and making weird crooning or rumbling noises.
When she does, just push into her backside and she should lower her front and raise her tail.

Breasts? Tamas are oviparous, anon, just like your trips.
