If you wish to keep the original lipstick, you best keep your dick out of her mouth. Otherwise, it will be damaged after one blowjob, and completely gone after 5 or 6. Ditto for acrylic water-based paint, usually gone in one blowjob. However, if you are like me and don't give a shit, she is just going to have to suck cock.
Plenty of lube, and she does a fair job without the damage normally associated with silicone dolls. However, makeup is a casualty. The good news is, it is easily replaced. Even without using the head for oral, TPE makeup usually needs a redo after about the 6 month mark.
This is just a sad reality of TPE dolls. The makeup lasts a hell of a lot longer on most silicone dolls, which are sealed in. TPE makeup is not. So whether you use the doll for oral or not, it is a matter of time before the makeup needs to be replaced.
Once the doll has been used for oral, it is imperative you clean the head properly. Otherwise, mold can set in. I remove the head, and wash it under a sink, taking care not to wet the threads or eye area. The threads can rust, and the eyebrows and eye makeup will fade and possibly wipe off, speeding the time you will need to replace it. Run your fingers in her mouth with water until the lube feels gone. Put a short tube (1/2" to 1" diameter) in her mouth (to keep it open) and lay her face down on a microfiber rag for about an hour, then turn her face towards a fan until dry, usually several hours. Remove the tube and she is ready to go again.
Lip gloss is much easier to apply than lipstick. It will also transfer to your sheets or clothing, and it may not ever wash out. It comes right off the doll though, and won't even last one blowjob. Powdered makeup works well, but also has a life span, and, it can smear. Eyebrow pencil works well for eyebrows and is damn hard to remove. Hope this helps.
