Her butt pushs out to ...ouch mine and I push gently against the pressure. We surreptitiously lean against each other enjoying the warmth and silent sharing. I chuckle and turn to lean against the door frame. She is behind me and to my right. Still chatting but I can feel her full attention on me. We are close. My arm & hand is against the doorframe.
