Cuddle sessions with Astarion would be ELITE.
He would savour every moment of non sexual intimacy like it was his last. You could place your head on his chest and listen to the low rumbles of his voice while he speaks to you. He would probably stroke your hair or cheek absent-mindedly while recalling the days events. He would trace the curves of your body lightly with his fingertips. Enjoying how nice it feels to touch someone without having to perform.
It would be such a lovely moment that you would definately fall asleep in his arms. Since he doesn't need sleep, he would just sit there enjoying the feeling of each breath you take, every heartbeat, the warmth of your skin on his. It's almost enough to make him feel alive again.
How about you doodle/draw Astarion on a clothes shopping spree, impossibly happy or teary or however you like, since he's had nothing of his own in 200 years
How about you doodle/draw Astarion just... Hugged. Loved. Cared for. Having his head patted. His ears caressed. Ticklish Astarion, maybe. JUST HIM. HAPPY.
How about you doodle/draw Astarion braiding beloved's hair (anyone, your Tav, Gale, Wyll, Halsin, a random Tav, Shadowheart even (I personally think they'd be besties and talking shit about everyone in camp in Elvish while they do each other's hair and nails))
How about you doodle/draw Astarion just sewing. Anywhere, any act, before or after the game. Just anytime.
How about- (I'm so sorry)
I loved the sewing idea and a little comic was born
