I would like to be on Vegtham's side.

I think Wesker can arrange that: it only takes a couple of actions. Vegtham breaks free, runs around, meets Vervolka, and raises him as a decaying zombie. Voila.

In everyday life, do you drink tea using telepathy without touching the cup with your lips?

No. If you read it carefully, it looks interesting:

lowering his lips into the cup

as if the werewolf puts the cup on the table - his face is parallel to it, his lips are pursed, and he sucks the liquid. The whole problem is in the word: lowering.
