Author's Note: Bear with me because I change the ages of the people in my stories because I can. (To the people who hate.) And I have a fucked up timeline so live with it.

Tony's POV

After Steve and I had our 'fun', I started to worry. I had just remembered that we are both Catagory Q males and have a chance to get pregnant, but I quickly discarded that idea. I'm 36 years old, and Steve is over a hundred. My drinking problems would surely affect that, and Steve was told he was a Category Q male back when he was in the army. There was no way we could get pregnant.

"Boss, T'Challa has arrived and I informed him that you wanted to see him,"Friday said snapping me out of my thoughts. "Where did you tell him to meet me?" I asked."I told him to wait in your shared bedroom, because the last time you had sex in the laboratory you were extra sore for days."Friday replied. "Tell him I'll be there in a few minutes. I need to get this oil off of me." I said as I started to put my tools away."Yes Boss."I went to the guest floor of the tower and took a shower in one of the spare rooms. I didn't have any spare clothes so I walked back in only my towel.

No one's POV

When Tony opened the door, he saw T'Challa sitting on the edge of the bed. When he saw Tony he had a look of surprise on his face. "Friday said that you wanted to see me. I didn't think you would show up wearing nothing." T'Challa said with a smirk as he stood and walked over to him. Tony shut and locked the door then turned to face him. "Ran out of clean clothes, and you know I can't do laundry for shit." Tony said when T'Challa finally reached him. "Maybe I should start hiding your clothes so this can happen more often." He said, in a low and husky voice, as he put his hands over Tony's that were holding up his towel. That made Tony's dick twitch. "What do you say we we have ourselves some fun?" T'Challa said with his signature smirk. "How about it?" Tony replied lightly tugging at his shirt. T'Challa got the message and starts to take his clothes off.

T'Challa finally takes off his boxers to reveal his already hard member. "Will you drop the towel now? It is nothing I haven't seen already." T'Challa said pulling Tony close by his hips. Tony instantly complied, dropping the towel at his feet. T'Challa moved in and kissed Tony. The kiss was full of lust and passion. Tony kissed back, and it soon turned into a French kiss. This lasted for all of five minutes, but it felt like forever for the both of them. They broke apart for air and Tony hid his face in T'Challa's chest. They stood there for a while, trying to catch their breath.

When T'Challa finally caught his breath he said, "Will you be a good kitten for me?" He said, using his fingers to push Tony's head up to look at him. "Depends on what I get out of this." Tony said licking his lips. T'Challa didn't say anything but turned around and got in the bed. He used his fingers to make the 'come here' gesture. Tony went over to him and was instantly pulled down. Tony saw T'Challa's member leaking pre-cum and did the only thing he could think of at the moment. He put it in his mouth. "Mmmm," T'Challa moaned.

Tony bobbed his head up and down, earning various grunts and moans from the older man. He could feel that T'Challa was getting close. He could feel his member pulsing in his mouth. He let go and heard T'Challa whine at the loss of contact. He then repositioned himself so that he was ever-so slighty hovering over the tip of T'Challa's thick member. He then lowered himself on it, his ass taking its sweet time to take the cock in. Tony out a small grunt when he got to the base. Tony quickly adjusted to being stretched out. T'Challa put his hands on his hips and picked him up slightly. Then roughly brought him back down.

Tony loved the heat pooling in his stomach from T'Challa's member. They did this for another ten minutes or so, then T'Challa was bored of it. Tony let out a gasp as he was flipped over on to his stomach. "A heads-up would have been nice." Tony said, once he found his voice, trying to look back at him. "Well then you wouldn't have agreed to this." T'Challa said as he slowly pushed in. Tony was loving every minute of it. They kept this up for a while, Tony's grunts slowly turning into moans. T'Challa was getting exceptionally faster with every thrust.

Tony was soon a moaning mess, something that seemed to happen whenever he was a bottom. "I'm getting close kitten." T'Challa said panting. "Me too." T'Challa did a few more thrusts and then went deep and let out his seed. The force of it set Tony off and he came all over the sheets. "Well that is one way to say 'Welcome home'." T'Challa said pulling out. "Yeah, and now I'm happy that Bucky gets home last." Tony said. "Why are you happy about that?" He asked. "Because he likes it rough and I'm already slighty sore from you and Steve." Tony repiled going into the bathroom, T'Challa following behind him.

Tony then started to run some bath water and added some oils to it. "I am sorry kitten if I had known I wouldn't have had sex with you." T'Challa said with a look of guilt on his face. "Well who said that I regret it." Tony said getting into the water. "Okay, but next time tell me, I don't want to hurt you." T'Challa said getting in behind him.

When they were done with their bath, they got dressed then went to the living room to watch a movie.
