Hands
Hotch realized that he was spending more and more time watching Reid's hands. Reid did most of his talking with his hands. Interestingly enough the rest of his talking was done with his eyes. Sure worlds came out of his mouth but if you had any hope of understanding it one only needed to watch his hands or stare into his eyes. And Hotch was positive that if he stared into Reid's soft brown eyes he feet would move of their own volition to stand in front of Reid. Then Hotch knew that his hands would move to Reid's face to hold it still long enough for their lips to connect. This was the only thing that caused Reid's hands to still and his eyes to close. This was why Hotch never looked directly into Reid's eyes when they were on the job but opted instead to watch his hands.
This changed, though, once they reached their home. It would change as soon as they reached their car, but Hotch had discovered that attempting to make out while driving was detrimental to their health and not nearly worth the risk. So Hotch had to wait until the front door was closed before he could finally claim his lover's lips.
At home, Aaron watched Spencer's hands for a completely different reason. Those hands which were so expressive when rattling off facts were that still at home. They were quiet when Spencer had conversations at a normal speed with Aaron. They were peaceful when Spencer slowly worked his way through a book (yes, Spencer could read less than 20,000 words a minute).
They were only moving for three reasons and Aaron loved all three equally. The first was when Spencer cooked. Spencer was an amazing cook; he claimed that it was all just a matter of science and understanding how the ingredients and flavors mixed. Aaron secretly believed that it was simply because Spencer enjoyed the art of cooking. Which was fine with Aaron because not only did he regularly get to eat a home-cooked meal but he also loved sitting with a glass of wine and watch Spencer's hand deftly wash, cut, and stir the dishes around him.
The second was when Spencer had any interaction with their son. A year after Haley's death Jack officially became the legal son of Aaron Hotchner and Spencer Reid. At first Aaron knew that the excessive use of his hands was out of nerves, almost like Spencer's shield that he would hide behind. Now, though, Spencer's hands moved out of excitement and joy for whatever the two were doing.
The last was actually the first Aaron ever got to see at home. When in the throes of love making, Spencer's hands were at their most expressive. This was when Aaron fell in love with Spencer's hands all over again.
If people like, I am thinking about writing a chapter for each of the three times. One for the first time Spencer cooks, talks with Jack (that one might be two) and for making love. Please review and let me know what you think.
