This caused him to cling to her and unconsciously beg for her approval.

Summary
A woman awakens to someone in her room.
---
A little yelp left my lips as the man lifted me as if I weighed nothing, and I hurried to cling to his body with my hands.His sudden roughness was a welcome surprise, as it felt like years had passed since I woke up with him in my room. I felt like this was all a dream.
That I would wake up the next morning and go into work with my coworker, clueless about anything I claimed happened.
I wondered if that would be the better reality in the end. This all was some desperate fantasy I came up with on a lonely, restless night.
