Astarion Is Basically A Feral Cat - Tumblr Posts

Astarion discovering that affectionate touch can feel good like a feral kitten that still grows while you pet it before slowly succumbing to chin scritches. Like he'll jump or flinch when someone taps his arm or shoulder, but when he realises it's Tav he'll relax. Or he'll tense at first when they run their fingers through his hair before just melting and practically purring into it

Edit bonus: Astarion also not wanting to seem desperate about wanting affection but also not really knowing how to ask for it so he just... puts himself in your way like, puts his head on your lap and puts your hand in his hair and pout. No words but Tav gets it and complies. Or he'll just drop his forehead onto tav's shoulder when he wants to be squeezed.
