This is basically daddy RDJ and Chris because I've never seen any so why not...especially since they're basically a couple 😉
dom!Robert/sub!Chris, blindfolding, edging, nipple play, cockring, oral (obviously male receiving), and of course we got the good old fashioned rimjob and the cherry on top...anal

Chris POV
Never in my life did I think I'd be in this position. You're probably wondering what position I'm talking about...we'll let me tell you. I've been submitted into darkness, blindfolded by a piece of silk, tied to the bed at my ankles and wrists, allowing me to feel the cool temperature of the room - my nipples are hardening as I feel a cool breeze blow by from Robert's mouth while he has me Tony Stark naked on his silk bedsheets (which I know will be ruined when we're done here), and a cockring on my hard dick refusing me need and want to cum later on.
All I can feel right now is Robert's naked lower-half subtly grinding on my painfully hard dick while he leans over to suck deep and dark hickeys into my neck. The sensation building to my need and desire to cum, although I know that that won't happen for at least another 6-10 hours...thank god it's our day off from filming because I know that I won't be able to walk tomorrow when we're done. He moves lower licking a line from my neck, that probably looks like I've been attacked by a wild animal, to my nipples making them even harder as he sucks so hard that he always tries to milk me.
I've noticed how much Robert loves my body so I try my best to work out as often as I can, just for him. He has obviously noticed the difference because after I've been blindfolded he makes it his mission to suck and kiss every single bulging muscle that I have...from my biceps to my thighs and calves to my neck muscles (which starts his journey on marking my entire body with hickeys). On times when I feel like being naughty, I decide to tease him by taking photos and videos of myself while I'm working out just so that he can enjoy them while we're away from each other, or her can use the photos/videos as encouragement to punish me (which I really love, but I'd never tell him that).
A moan erupts from my throat as I can feel my dick rub up against Robert's ass...oh my god it's making me feel really close to cumming, but unfortunately I know that I can't cum because of the obvious cockring which won't let me, and the fact that if I cum too early then I'll get punished more than what Robert would already have planned. Even with my sight blocked I can tell that he's smirking at my reaction because he then rubs his ass against my cock with more force and power while he also hums slightly at the pleasure that he is receiving.
Sliding down my body, Robert is now sat on my calves with his chest resting against my thighs and his mouth is mere inches above my twitching shaft. I can feel his breathe on my cock every time that he exhales. he isn't even touching me right now and all I want is to cum either in his mouth, on his face or on my body...sometimes I really hate being in this position.
Robert POV
As I slowly exhale over the tip of Chris' dick I was in wonder at his abs clenching and unclenching in pleasure of my proximity to his hard rod, and from the desperation that he has to cum so early. With my mouth so close to his dick I decide to be a tease and place a light chaste kiss to his tip and reach up his body and gently squeeze one of his nipples. he seams to really enjoy that based on the dirty moan that erupts from his throat.
What Chris doesn't know is that after I blindfolded him I secretly brought him back to set because I need to be back here early ish tomorrow. So while he is moaning like a common whore, all of the cast and crew that are still on site can hear him...and it makes me feel really good to know that I am the one that's making him feel this way. As he moans loudly I decide to up the pleasure that he feels by slowly and gently lowering my mouth over his whole length...it always amazes me how big he gets when I'm the one giving him the pleasure. Maybe it's because of the cockring or maybe it's because of how long it's been since he's last cum from my actions, but as I lower my mouth, his moans get longer and louder to the point where they're basically screams combining my name, daddy and oh god.
