Clint sees everything, no matter the situation, no matter how many naked bodies there may be to distract him.

Alright, look, confession - Tony has been masturbating to Captain America since he was thirteen.

For an LJ avengerkink prompt: Steve is very confused/weirded out by the distinct lack of pubic hair on modern women (or at least the women Tony has forcibly exposed him to). Sure he's a virgin, but he's seen naughty pictures/European burlesque shows. Therefore he's more than a little apprehensive when Natasha finally gets her panties off. Luckily she's a firm believer in giving her partners something to hold on to. Steve goes wild. +1 - it happens during group sexytimes and all the others stop what they're doing to watch Steve eat her out

Tony isn't so much introducing Steve to twenty-first century sex as enabling him. Steve already knows what he wants.

From the Avengers Kink Meme: http://avengerkink.livejournal.com/11065.html?thread=24876857#t24876857 "So Clint is Phil's sub. And he's stubborn and insolent and gets in trouble fairly often. He's always implying that he and Phil are really hardcore, and after a rough patch where he gets punished a lot, his friends start to worry for his safety. In fact, Clint is the gooiest, subbiest sub that ever subbed with Phil, who is incredibly gentle with him and heavy on the pampering and praise. Clint basically lives to be petted and told what a good boy he is, and his punishments are things like timeouts and very light spankings with Phil calmly telling him how disappointed he is in him, which is enough to bring Clint to sobbing contrition. So I guess there's some voyeurism or something, I just want this dynamic and the world at large seeing a radically different one. All the bonus points for some compare/contrast with Pepper and Natasha who are outwardly nearly vanilla when in fact they do crazy edgeplay and heavy pain and just don't tell anyone about it."

Sex gas, Latveria, and a SHIELD orgy.

Tony Stark is all about the advancement of science, but...he probably should have clued Steve in a little sooner. Steve just thinks it's a bad idea to volunteer for anything that involves Reed Richards.

Tony’s almost at the door of his lab when he hears it. It’s low, throaty; just a split second of a thing. But it’s undoubtedly the sound of Barnes moaning.
