#dirty speculation

Bucky is so sensitive to touch that anywhere and everywhere is good for him.   Neck and collarbone is a favorite.  As is along his hips and the line of his adonis belt.  Down his chest.  He’ll even take being kissed along his scarring if it’s done tenderly and briefly.  When he’s ready for that kind of intimacy it’s all his favorite.

As I said in the post about sex between them, With Thor and Bucky, you’ll have two very strong large guys who have the same view of sex being fun and enjoyable but who need to come at it at two completely different times and speeds.

You would start having sex with Thor much quicker than with Bucky.  There’s a chance sex with Thor was happening before the three of you even were in an official relationship.  Bringing Bucky into that would go slow, but Thor is kind and patient.  He’d never push the other man to do things he wasn’t ready for, and he’d make sure anyone else that was with them was equally patient.

Once the three of you hit your stride things would be very spontaneous and tactile.  You’d always be touching each other, whether it be sexual or not.  There would be a lot of starting up everywhere other than the bedroom.  They’d both worry about hurting you if they used their full strength, so while they’d like showing off a little, but lifting you up an fucking you against the wall, it would tend to lean on the more gentle side.  There would be things they did with you that neither would do with the other.  Thor, for example, would love to do electrostimulation but he’d never try that with Bucky.

Their favorite things would include:

Oral Sex:  Thor in particular is a huge fan on going down on people, and why would either of you stop him.  They would very much like Daisy Chains too.

Train:  The closeness and each of you being spooned by another while you were all connected.  Bucky would adore being in the middle of a train though it would be the way to make him come the fastest.

Public Teasing:  Not always, it needs to be the right time and place.  But at a stuffy event that isn’t important, they are both going to be into a good distraction.

Double Penetration:  However you want to take them both they’ll happily oblige.  They love how they can feel each other while inside of you.

Well, he canonically heals quickly due to a fast metabolism that makes his cells regenerate faster.  Plus, he has superhuman stamina.  So not only could he go round after round after round, those rounds could go for hours.  So if you were into fucking until they literally passed out from exhaustion and were unable to walk the next day then he’s your guy.

Steve would definitely be quiet initially.  You’d get soft moans and grunts as he tried to hold himself back.  He’s quite reserved when expressing how he’s feeling and he doesn’t like looking stupid.  It would also take a lot for him to get to the level of physical exertion he requires to be panting.  You’d have to have superhuman stamina or speed just to get to the point where he’d need to be panting.

But Steve’s biggest thing is knowing his partner is enjoying themselves.  If he can hear them it’s a turn on, so it’s likely that that will feedback into a realization that his partner might want to hear him too, and those moans will get louder, he would start talking a little more, ‘oh god’, ‘like that’, ‘that’s it’.  He might give dirty talk a go (though it’s really never going to be what he’s good at).   The more his partner showed they liked his sounds the more he’d relax and let himself make them.  He won’t ever be a screamer, but with the right partner, he could get to be quite vocal.

As I’ve said so many times, Steve isn’t sex motivated, so he’s not going to push for something like that.  Nor is it ever going to be his favorite way to wake up.  I mean, just for starters, to be awake before him at all you’d be waking before dawn.  But if you did really feel the need to get him up before the sun he’d rather cuddles and soft kisses than sex, because he’s far more romantic than sexual.

But if you asked first, and said you wanted to try it.  He’d agree.  He’d wake pretty quickly as he sleeps lightly, he probably wouldn’t even be fully hard yet.  When he was fully aware of what was happening he’d submit to you completely, letting you take control while he was still in his sleepy state to do with him as you wished.

This is hard to answer fully due to the fact that we don’t actually know the severity of Rhodey’s paralyzation.  We know he can’t move below his waist without the artificial legs Tony created but not how it affects his sexual function, and that’s both important, and not something I like to just make assumptions about.

Prior to the accident, they’d be mostly about the silly stuff.  Tony is definitely the more submissive of the two and while things would definitely get intense between the two of them, with Rhodey acting as the dominant, as well as just loving sex in the bedroom, mostly it would be about Tony just seeing how far he could go teasing Rhodey before Rhodey shoved him into a janitors closet or the nearest bathroom to teach him a lesson.

There would still be a lot of that, but mechanically it would likely be different.  There would be more toys and devices involved now and anything spontaneous might just involve being fingered or jerked off roughly.  Maybe not though.  Like I said it really depends.

Tony is still the more submissive.  Not always obviously.  Tony likes to switch it up and always has.  But mostly he falls submissive and Rhodey mostly falls dominant.  They both are mostly about having fun with each other.  Tony is still all about teasing Rhodey until he gets a reaction.  Even if that reaction is ‘you’re in for it later’. 

Their favorite things to do would include:

Powerplay - Tony does not like to give his submission easily and Rhodey loves earning it.

Public teasing - Rhodey pretends he doesn’t like Tony being the little shit he is, but he really loves it

Semi-public sex - as much as they can get away with or do given both of their restrictions

Frottage - they can get very tactile during sex

Bondage - Even if it’s just Tony’s hands pinned behind his back, Rhodey does like to make sure Tony knows who’s in charge.

Bucky is both sexual and likes fun and spontaneity with his sex life once he is comfortable with his partner.  Car sex falls right in the middle of what he likes best.  Obviously, he’s a big guy and car sex is awkward and uncomfortable even for slight people, but that giving into desire right in the moment, regardless of the consequences would be a huge turn-on for him.  To have the person he is with just need him right then and there and for him to have not only that brief window of time but that level of comfort with a person that he can do something that’s a little bit dangerous just because the two of them can’t keep their hands off each other, would be something he loved.

You know with Tony he’s got one of those giant shower stalls that could probably fit a whole legion of people into them.  So space is never going to be an issue.  While he might go into the shower with someone else just because he’s in a rush and there’s already someone in there, but going off his reaction when Pepper suggested they take a shower together in Iron Man 3, it means sex.

There is a thing Tony does too when he’s initiating sex where he’ll make two very obvious lead-in moves and then stops and lets the person he’s with take over.  He likes people who are sexually aggressive.  So for him, he’d start kissing you.  He’d grind up against you and kiss your throat and then he’d let you take over.  Sucking his cock under the showerhead.  Or getting him to sit back under the water as you ride him and he drinks the water directly from your skin.
