Astarion probably isn’t used to aftercare with all his trauma regarding sex / intimacy.
So imagine after the first time with you, almost immediately after you both finish, he gets up to re-dress. He expects you to do the same and leave, just like everyone has before you. But instead, you tug him back down into your warm embrace. He’s frozen, unsure what you’re doing but he likes the way you play with his hair. It slows down his erratic post coital heart, as his head relocates to your chest. Astarion comes to the realisation that he’s never actually taken a moment after sex to calm his body down before. It’s nice. You stay like this together for a while, relaxing after all the physical movement from earlier.
‘You okay?’ You mumble to him in a tired haze, ‘Did it feel good? You want some water?’ You begin to sit up, disrupting his position on your chest. For once he doesn’t reply, no flirty quips ready on his tongue. Astarion finds himself half shocked, half in awe that you care how he feels and what he felt like during the act. No one’s ever asked him that before.
You leave the bed briefly to the bathroom and return with a washcloth. You wipe yourself off then gesture towards Astarion, ‘Is it okay for me to clean you?’ You say softly, asking his consent.
He coughs, clearing his throat, ‘Of course,darling,’ he says, clearly covering up his confusion and rising nerves. ‘Are you okay?’ You ask again, repeating the question from earlier.
‘Yes, my love, I’m fine... it’s just no one’s ever done this to me before,’ he states gesturing down to where you carefully wipe his inner thighs. ‘Oh!’ You stutter ‘I can stop if your not comfortable with it—’. ‘I love it.’ he states, cutting you off. Eyes staring warmly into your own.
After this scenario happens I feel like Astarion will make the extra effort to learn proper aftercare for you, he begins to realise how important it is to check in after sex, he never wants you to feel used like he did in the past.
