Apologies! Thought I had queued this up 馃ゲ
Touch repulsed/touch starved vs only person you actually want to touch you. Portia probably sus鈥檇 it out a long time ago and respects it, so combination of being asked for permission + she knows just the right way to do it (aka TIGHT squeeze) plus smells good and is comfortable. Thrill of making ur crush happy. Again, Edwin鈥檚 an act of service girlie, he doesn鈥檛 need the praise and works in the shadows because it鈥檚 overwhelming otherwise, gets a lot of pleasure from making Portia happy. Obvi her gratitude/love is also welcome 馃槀 plus she鈥檚 a words of affirmation type (which he seeks out) so being complimented etc feels GOOD BRO
