You and Matt have been dating for 4 months, but you have never really cuddled or anything like that because you've had a very bad past with relationships. They were toxic or even abusive so you we're just terrified to give any affection at all. You pretty much gave up on love until you met Matt, he showed you that love was possible and he was very patient with you, he wasn't gonna force you to do anything with him until you were ready and you were so grateful for that.
You were over at his house. You were both in his room lying on bed next to each other watching a movie on his tv. It was already 10pm so you were a pretty tired, and halfway into the move you fell asleep, on Matt's shoulder... This was probably the most physical touch you two have had so far so Matt was pretty.. shocked, but he wasn't complaining
