Wow. What a wonderful, different story. I loved the tenderness, calm and lack of hatred in it.
Your Harry was quite unusual, and very appealing. I think I was as mesmerized as Severus by his gentle and understanding words and by his soothing strokes. Potter's hand was stroking him like one gentles a nervous horse was an accurate description. I like the idea that Severus noticed that.
The snogging and the lovemaking were incredibly sensual, and Severus’ reactions to them believable. I loved to see him become more active and yet remain so very insecure.
