The first time Roy kissed Riza she punched him on the face, surprised at his action. They were teenagers and living together on her father's house for over a year, while he learned about flame alchemy. She had a quiet and gentle personality, contrasting with Berthhold difficult and rispid up-bringing. After noticing how hurt the dark eyes were over her, Riza gently touched his bruised cheek, before kissing him back.

As her clothes were discarded on his bedroom's floor, Mustang touched the beautiful tattoo on her back and kissed her skin like something sacred. Her father had died and it was a long and painful day. He was going to leave again on the next morning and he wanted to engrave her taste on his mind.
#3
When they were finally alone and all the other soldiers on camp went to sleep, Roy hugged Riza tight. "I missed you", he said against her neck, before kissing her deeply. Although it pained him she had become a soldier, his heart was content on seeing her again. If that horrible war could bring any goods, was the chance of being together one more time.

Riza watched Roy crying in silence for all those people he killed on the Ishval Civil War. His body was trembling sitting on his bed and his hands were over his eyes. She kneeled before him and kissed him gently, before hugging his body and silently comforting him during those dark hours.
#5
Riza's hands wondered on his dark hair as she kissed him while making love in a small hotel on the outskirts of Amestris. The war had ended and they were clear to go home. Since Hawkeye didn't have any place to go, they enjoyed each other's company, trying to soothe the desperation of such horrible days with their bodies.
That was the place he burned her back. And he kissed her thousand times, silently asking for forgiveness. Although being the strongest woman he had ever met, he was not able to do it completely. He stayed by her side and took care of her wounds for many days.
Mustang kissed her goodbye before leaving her one more time, his heart torn in two.
#6
After Hawkeye agreed to follow him even to hell, Roy ran to her and kissed her hard. "We are never going to be apart again." he said, holding her face with both hands. She just smiled and whispered "Yes" quietly, before kissing him again.
#7
Roy kissed her hard as soon as they returned from Maes' funeral. He looked at her seriously. "Dont you ever die on me. It's an order." She touched his face slowly with her fingertips, before nodding silently, her lips over his as he held her tight almost to the point of breaking.
#8
The first and only time Roy said "I love you" it was on the hospital room after the wound on her neck was taken care of. Riza saw the fear of losing her on his dark eyes and said "I'm sorry", before kissing him lightly.
#9
The first thing Roy did as the moving for the Armstrong's mansion was finally complete was kissing Riza hard after the doors of their newest home were closed behind them, on complete privacy.
#10
When Hayate died at the age of 15, Roy got depressed for a long time. On Christmas's, when he finally returned home after spending the day at his office, two puppies welcomed him, jumping on his feet and kissing his face as he sat down. Riza smiled at them as seeing him so happy. They were Hayate's descendants from the Army's kennel and were freed from duty for being "too goofy".

On Mustang's 40th birthday, Riza woke him up with a kiss, before bringing him a special breakfast. He couldn't eat his French toasts as Heckler and Koch were able to steal them from his plate. Roy just laughed at the dogs and Riza scolded them, telling him he was too soft.
*Heckler and Koch are German snipers rifles' names.
