Steve's Release of Pressure

Another Session

Steve was getting mentally prepared for his third session of milking per the stupid medical staff's recommendation with Tony and Bruce and so far they have been successful but have remained at the recommended four hour time mark and Steve still refuses to let Jarvis record anything to Bruce and Tony's disappointment. Steve has found himself so much more relaxed and almost playful with his boys and all three of them have noticed a difference in the bedroom as well as out in the field, of course the Team would never mention anything to Steve directly, but they all know something has changed with him for the better so they just kind of roll with it.

Bruce and Tony had informed Steve that they have something different for him for this session and hoping he would want to try and go for five hours today instead of the recommended four so they have been withholding sex from him for the last two weeks and not allowing him to pleasure himself at all while having to endure watching Bruce and Tony fucking and kissing each other. To say Steve has been very tightly strung, ready to take anyone's head off if they breathe to loud and walking around with a perpetual hard on is an understatement. Steve could not get down to the room and naked fast enough even with his hesitations that have been looming in the back of him mind.

Once Steve arrived in the room he began to strip down till he was bare and grabbed the towel that was laid out for him and wraps it around his waist while watching Tony and Bruce doing some last minute checks on the equipment. Bruce had mentioned to Steve awhile back that when Tony was not working on the equipment for Iron Man or the Team and the SI business was handled for a time he would go down to the room and fiddle with the equipment for him, always checking to make sure it was safe and secure and how to make it better and more pleasurable. Steve turned a lovely shade of pink knowing Tony was thinking about him and his comfort and safety to the point that when Steve saw Tony next time, which happened to be in the entrance to the kitchen full of their team mates, he wrapped Tony in his arms, backed him into the corner of the room, hiked him up till Tony wrapped his legs around his waist and took his time to kiss him thoroughly till they were both panting. Without a backwards glance from Steve, he proceeded to walk them into their bedroom and fuck Tony stupid; it was a very enjoyable afternoon for both men.

Bruce looks up and notices Steve standing in his towel and smiles brightly over at him, "Hey, you ready?"

Steve looks at the new set up, if Steve heard Tony correctly it is called a bondage bench, were this time he will be laying on his stomach ass up and exposed, legs bent at the knee with is calves strapped down and cock hanging down between his thighs in the vacuum sleeve and his arms will be strapped down as well, there is a U shaped head piece to lay his forehead on with an opening for his nose and mouth as well. Steve noticed it was wide enough to support his broad chest and shoulders and it looked like Bruce and Tony added extra padding to the bench since they want to try and go for five hours this time.

Steve just shrugs his shoulders at Bruce in response. Bruce walks over and places his hand on Steve's chest feeling his rapidly beating heart.

"You'll be fine. You know what to expect now and Tony and I will be here the whole time."

"I know." Steve says with a sigh.

Tony was listening with one ear to Bruce and Steve's conversation and turns his full attention to them and really notices Steve's hesitation now as well and walks over to join his boys, equipment forgotten for the moment.

"What's up Cap?" Tony asks.

"I don't know, it just feels so clinical and cold I guess" Steve says looking down at the floor.

"Well we are changing things up a bit today, but if you really don't feel like you want to do this we can forget it and head back to our rooms and do it the old fashion way." Tony replies easily.

Steve doesn't reply still looking down, even after having a few sessions Steve is still embarrassed he has to do this at all. Why him, it's bad enough he can't get drunk and barely ages but this to…really.

Bruce watches Steve very closely as he slowly sunk further inside his head having a pity party and decides to take control. Bruce reaches up to the back of Steve's head and pulls him down for a kiss, soft and sweet. His tongue rubbing back and forth on Steve's lips asking for entrance. Steve gasps feeling Tony placing open mouth kisses across his back and spine. Bruce takes advantage and sinks his tongue into his mouth, twisting and thrusting, teeth clashing together. Tony takes his mouth lower and lower till he was at the top of the towel, then works his way back up to Steve's shoulders and neck, his hands massaging Steve's muscles and all his soft beautiful skin.

Bruce left Steve's mouth, both men panting and begins dropping kisses on Steve's smooth pecks and runs his tongue around one of Steve's nipples before sucking it hard into his mouth. Steve gasps, after not having any kind of attention for the last two weeks his towel is quickly rising from his over flow of lust and passion from his boys.

"God Bruce…..Tony…so good" Steve moans out.

"How you feeling now Cap, still want to go back to our rooms?" Tony asked while nibbling on his ear.

"Mmmmm…..want…..god Bruce…" Bruce had moved to his other nipple while fingering the first one.

"Stay" Steve pants out.

Tony whispers to Steve, "Good boy, we are going to take real good care of you baby like we always do."

"Ha…ha…ha….I…I know…..god" Steve is getting overwhelmed and beginning to leak onto the towel.

"Tony I think we need to get our boy moving." Bruce says eyeing the towel wrapped around Steve.

Tony reaches around Steve from the back to release the towel, delivering even more kisses to his spine and shoulder blades till Steve is standing bare, his cock standing at attention and leaking at its tip. Bruce and Tony walk Steve over to the bench and help him climb on, maneuvering his arms, legs and head into place and quickly strapping him in leaving Steve's perfect ass in the air to be fucked. Bruce grabs the lube and slowly starts working the tip of his finger into Steve's opening, causing him to moan.

Tony begins working Steve's cock, pulling and rubbing the head making sure he was nice and hard. Tony grabs the lube from Bruce and generously coats Steve's cock and then the upgraded vacuum sleeve, this one is longer in order to hold more of Steve's release and if his cock grows in width and length then it's a bonus for Bruce and Tony when Steve fucks then unconscious which Steve loves to do. Tony thinks its pay back for the sessions, not that him or Bruce are complaining one bit, god bless America, Captain America that is.

Bruce now has worked all four of his fingers and thumb up to the knuckles into Steve, who is moaning and panting.

"Please…." Steve cries out, but doesn't receive a response, but Bruce pulls out his fingers leaving Steve open and empty and cock leaking. Tony quickly places the vacuum sleeve around Steve's cock and pushes it all the way to the root turning it on at the slowest speed to start the suction.

"Aaaaa…mmmmm…god" Steve moans out at the pull on his cock as it lengthens and swells in the sleeve. Tony makes his way up to Steve's head that is face down and begins to massage his neck and shoulders.

"Alright baby, Bruce is going to fill you up and then we'll get started, just relax….hm" Tony says calmly while still rubbing as much of Steve's skin as he could reach.

Bruce pulls over the machine with the attachment, something different was added this time. It is still ten inches and about three fingers wide with a nice mushroom head, but what Bruce added was a cock sleeve onto the attachment covered in thick knots and nubs that will rub on Steve's walls and push on his prostate with every thrust. At one point Bruce knew Tony was looking into how to make it vibrate but thought that maybe too much for Steve, but maybe in the future. Bruce applied a liberal amount of lube and began to slide it into Steve till it was about half way, the knots catching on Steve's rim and making him cry out.

Tony is till massaging Steve's back as Bruce walks over to the controls and turns on the machine and watches it sink into Steve to the hilt and then pauses it, causing Steve to moan and flex around the attachment.

"Bruce….full…." Steve whines.

Bruce massages Steve's cheeks giving them each a little love taps.

"I know you are baby, this little beauty is going to rub on your inner walls and push on your prostate for the next five hours. Now you just relax and let your body do what it needs to do, how's that sound … hm?"

Steve groans.

Tony leans down to Steve's ear and gives it a nibble and whispers, "We'll be back to check on you in a bit but we still have a few surprises for you, raise your head a bit babe." Tony places a breathable gag into Steve's mouth and tightens it behind his head gently laying his forehead back on the cushion and gave Steve a kiss on the top of his head. Tony walks away to the control panel for the sleeve, slowly speeding it up watching Steve's cock push and pull, Bruce also turns up the attachment to a steadier thrusting.

Steve moans deep.

-2 hours later-

Steve has been steadily fucked for two hours and has orgasmed multiple times slowly filling up the sleeve that is pumping his cock. His cries and moans are constant and Steve is covered with a layer of sweat. Tony slows the attachment down a bit to a nice easy thrust and walks over to Steve's head.

"Hey babe, you're doing so well." Tony runs his hand through Steve's sweaty hair. Steve looks up at Tony his eyes glazed over with lust.

"How's the cock feel? Our Bruce added something special to it for you babe, you feel them don't you? Every time you tighten around the cock as you cum they rub you even more don't they. "

Steve moans; he feels another release coming on as the sleeve is pulling on him hard.

"You're getting ready to cum right now aren't you babe?" Tony starts massaging Steve's back and spine. "God your muscles are so tight Cap, you've done such a good job today, two hours in and already the sleeve is slowly filling with all your creamy goodness." Steve is getting tenser, he's so close.

"Just let go babe" And Steve does as his body locks up, arching his back as much as the restraints allow and screams from behind his gag. Bruce watches as the attachment continues to fuck Steve through it and slows the sleeve down a bit. And so it goes on.

-Another 2 hours-

Steve has hit the four hour mark and it was Bruce's turn to check on him. Tony had the attachment currently working Steve at a feverous pace so Bruce set the sleeve at one as well. As Bruce passed Steve's hips he was amazed again how much of Steve's release they had collected and was currently jumping and sloshing around in the sleeve saturating the head of his cock keeping it slick. Bruce reached out to gently pet Steve's head and slightly pulled it up so Bruce could see him. He has sweat running down his forehead and temples along with tear tracks on his cheeks.

"Aaawww baby, you're working so hard. We're so proud of you, you've made it to hour four and as a reward Tony got some special oil that I'm going to massage you with, okay" Steve just moans.

Bruce pulls the bottle over and pours a generous amount into his hands and begins to work it into Steve's back, shoulders, arms and working his way down to his hips and even to Steve's ass cheeks and thighs. As Bruce works the oil in Steve notices that his skin is getting warm and tingly, and releases another deep groan. When Bruce is finished he comes back up to Steve's head noticing that Steve was squirming and flexing his muscles.

"Do you like it? This oil is special, it warms when contacted with air, feels real good doesn't it." Bruce smirks down at Steve.

"We want you to cum as many times as you can in the next hour baby so hold on okay" Bruce places a quick kiss on Steve's heated shoulder and walks back over to the controls for the sleeve.

By the end of hour five, Steve was crying and sobbing from the bombardment of sensations, he was at his limit. His release of creamy cum filled the sleeve up to almost over flowing barely leaving any room for his cock, every new ounce that was shot out was now back flowing around Steve and trying to leak out at the base and drip over his now empty sack.

Tony slowed the attachment down and pulled it out of Steve's wrecked hole. Bruce pushed the sleeve up to its highest speed and then walked over in between Steve's thighs, dropping his pants and shorts pushed in to the root and once again ever so slowly started to turn green and began to fuck into Steve, causing him to arch his back and scream. Tony comes over to Steve's head and unhooked the gag and kissed Steve roughly on the mouth.

Steve pulled away to pant and moan. "Fuck….fuck…oh god."

Tony pets Steve's face and tells him to cum again.

"Come on Stevie you need to cum a little more or Hulk will just keep going." Tony soothes Steve.

"Tony…." Steve pants. "I know baby, I know….I'm just going to reach down and release the head rest and I'll help distract you till he's done, hmm"

Tony opens his pants and drops them and his shorts to the floor giving his leaking cock a few strokes, then presses the release button and catches Steve head gently and begins to rub his cock across his lips till Steve opens and takes him down till Tony is balls deep and begins to thrust into Steve's wet and sloppy mouth.

"God baby your mouth feels so good." Tony begins to speed up.

Bruce has turned a nice shade of green and is thrusting into Steve with abandonment.

"Me like, tight, feel good, more." Bruce lets the hulk go completely and grows to his full size his cock pushing against Steve's walls painfully and causing his hips to widen. Steve pulls off of Tony's cock to scream and begins to spasm, his cock spurting out copious amounts of cum that now is escaping the still pumping sleeve and dripping onto the floor.

"OH GOD…. AAAAAA…FUCK…FUCK…." Steve is wrecked. Tony leans down to Steve's face and whispers in his ear "Good boy" and slides his cock back into his mouth and begins face fucking him.

Tony and Hulk were close and Steve was just hanging on having no control over his body anymore.

"I'm close baby you ready to swallow me down; here it comes….AAAAAA…..FUCK!" Tony shoots his load down Steve's throat as he tries to swallow it all down. When Tony is done he pulls out and grabs the head rest and brings it back up for Steve to place is head on while he quickly grabs his pants and pulls them back on. Steve is left panting from Tony's release and still being hammered by Hulk.

"Please…..please…." Steve cries.

Hulk is close, his thrusts start to become hard and erratic, he give one, two , three more hard thrusts and he lets out a roar and cums, spilling deep into Steve expanding his belly under his six pack abs.

"AAAAAAAA…fuck….full….to full…..oh god….please….please….fuck please" Steve is sobs.

When Bruce begins to shrink down to his beautiful pink skin and pulls out of Steve there is a rush of cum pouring out after him. Steve is crying from the sensation and relief from the pressure on his innards and inner walls from the Hulk.

Bruce grabs his pants, pulls them up quickly and walks over to the controls of the sleeve and begins to slow it down to a stop. Tony begins to unstrap Steve's arms and Bruce his calves, both men massaging his muscles as Steve still continues to whimper and cry from the pounding the Hulk gave him.

"Shhh baby, you're almost done we just need to release the sleeve, hang on love hang on for me, we got'cha." Tony cooed to Steve.

"Bruce he's fading fast, we need to get him to the bed." Tony told Bruce with urgency.

Tony continued to coo to Steve as Bruce worked to release the valve on the sleeve, once Bruce came to the final twist he called up to Tony, "Brace him Tony." Tony wraps his arms around Steve's shoulders to hold him whispering in his ear how he's a good boy and he did so well, then Bruce made the final twist and the sleeve released for Bruce and he began pull it down and off Steve's saturated cock. Steve cries out in Tony's arms, his body twitching and his eyes rolling in his head before going limp in Tony's arms.

"Damn Bruce"

Bruce stands up holding the sleeve to show Tony a very good possibility that they collected close to a quart this time. Bruce puts a cork in in the top and lays it down on the side table while grabbing a cloth for him and Tony to quickly clean Steve up and check for any damage that may need their attention.

"Damn he's wrecked" Tony comments.

"Yeah, it will take him a bit to heal up so we will probably want to put him on light duty for a few days." Bruce replies.

"Good idea, we can pamper him for a bit to make up for the two weeks of going without. Did you see him about takeoff Clint's head the other day for chewing to loud, I didn't know if I was supposed to laugh or be very afraid." Tony chuckles.

"Oh yeah be afraid, he went several rounds with several punching bags in the gym that you may need to replace by the way Tony."

Tony smiles down at Steve, "I'll take care of it later."

Steve starts to come around as Bruce and Tony finish cleaning him up and get ready to move him to the makeshift bed they have in the room.

Steve moans.

"T-tonyyy…..Br-ruccce" Steve's words sound slurred.

Bruce comes up on one side of the table and Tony the other to help lift Steve up with his arms around their shoulders, then shoot his legs back till his feet touch the floor when his legs promptly give out on him and the boys have to support his weight.

"Hey baby, you did so good today." Bruce coos "Let's get you over to the bed, hmm"

"M'kay….Hi Tony" Steve looks at Tony with a loop grin on his face.

"Hey Cap, feeling pretty good huh?" Tony asks. Steve giggles, he actually giggles.

Bruce looks at Tony over Steve's head raising an eye brow at him and Tony raises one right back. They make it to the bed and lay Steve down on the bed, strip down and join him all cuddled up and tangled up, Bruce pulls a light sheet over them and all three drift off into a peaceful and sated sleep.
