"Breathe baby!" Tony pet Steve's face as he grunted, desperate to move. "Hey baby, it's okay. You need to relax. Take a deep breath." Tony took a deep breath to mimic what Steve should do.
Instead, Steve closed his eyes, trying to relax.
"Hey Stevie, open up!" Tony playfully slapped Steve's cheek twice. "Come'on Cap! Open your pretty blue eyes!"
Steve just started breathing faster and shut his eyes as tight as he could.
"Open." Tony repeated, less playful. "Steven. Open." Steve didn't.
Steve made a loud noise- a mix between a choke and a grunt. A bright red mark was plastered on the side of his face, it was the reason he had made that pained noise. Tony had slapped him harder than ever before, which also slapped his neck to the side.
"T-T-" Steve tried to force Tony's name out. Instead, he was met with another painful slap. "T-"
"Stop trying Steve." Tony got off the bed and turned toward the door. "You ruined the mood. We were having a good time and you ruined it. So typical of you." Tony then circled back to the bed and sat down, facing away from Steve.
"Sometimes I wonder why we are still together. Whenever we spend time together we fight, then you make me mad, so I hit you, and usally you shut up. But sometimes you don't and then you make me hate you. How can I love and hate you? And I still don't want you to ever leave." Tony laid back and snuggled up to Steve. "Ya know I drink because of you. It's your fault. All I want to do is have fun with you, but you always get mad at me. But then I give you those black and purple bruises, and I feel better." Tony ran a finger over Steve's cheekbone. "You look so hot with those bruises. When I look at them I feel like I own you. I pretty much do. I'm never letting you go. And you'd be dumb to try. You're too weak for that." Tony sat up on the bed and scooted to the edge. "It's just you and me, Steve. Because we love each other."
And then Tony left.
Steve grunted. He could now move his fingers slightly. He kept wiggling them until he got tired. Then after a brief moment of resting, he started wiggling his fingers again. Then his toes.
After a few minutes, he could finally move freely, but he was still tied in the bonds from Tony. He could easily break them, but he didn't want to upset Tony. All Steve wanted was to make Tony happy but, somehow, he was the reason for all of his misery.
Steve loves Tony and he had to be better. He has to.
