Needy Omega
It's mid-morning and Steve is already tired, well he is 5 months pregnant. His baby bump is starting to show but not quite enough to get in the way of most of his normal activities, but god is he tired and horny as hell. Once Steve got pregnant his heats stopped as they were no longer needed and once he got through the first trimester of not wanting his Alpha to even look at him to say nothing about touching him which left his poor Alpha with a serious case of blue balls did he finally settle and they have been enjoying some seriously fun times in the bedroom among other places in the suite apartment of the Stark Tower.
Steve was propped up on the couch with his aching feet raised on the couch pillows reading another baby book waiting for his Alpha to finish in the lab and head back home. While one hand holds the book open for him to read he reaches down with his other hand and begins rubbing his rounded stomach enjoying this quite time with just him and their pup.
"You going to be a good pup for your Papa and Daddy aren't you?" Steve says down towards his belly and gasps when he feels a slight fluttering in his stomach and can't help but smile.
Steve is also noticing in the last few weeks that his pecks are becoming fuller and thicker while his nipples have started to become overly sensitive much to his Alpha's delight as he loves to play with Steve's nipples and has recently been even more attentive to his buds. Just thinking about his Alpha's mouth and tongue on his chest causes Steve to let out a deep moan, putting his book down and unbutton his shirt just enough that his hand can fit in to finger one of his nipples. Pleasure shoots through Steve's blood, down to this cock causing it to stir and his hole to become slick hoping his Alpha would hurry, Steve let's out another moan.
Steve continues to massage his pecks and nipples, eyes closed while his hand continues rubbing across his baby pump and completely unaware that Tony his Alpha had entered their suite. Tony could smell his excited and aroused Omega's scent as soon as he stepped through the door and decided to just stand and watch for a moment as Steve continues to touch himself letting out little sighs and moans of pleasure, his scent continuing to get stronger as his lust and need for his Alpha grows.
Tony can no longer wait and makes his way into the living room and kneels next to the couch so his hands can join Steve's on his bump, startling Steve causing his eyes to pop open with a gasp.
"Alpha" Steve moans.
"Right here love and how has our pup been today" Tony asks.
"Mmmm" Steve moans out, still playing with is nipple now hard and pronounced, "Good, felt a little flutter earlier" Steve let's Tony know as he lets out another moan, his slick now leaking through his pants.
"Alpha" Steve wines.
"My omega is so needy" Tony coos as he leans up to kiss Steve on the lips gently before pulling his hand away from his chest causing Steve to whine.
"Tony please, I ache"
"Where love" Tony asks as he begins kissing down Steve's neck to his bond mark on his neck and begins sucking and licking at it, Steve gasps in pleasure their scents now mingling.
"Everywhere" Steve groans out making Tony chuckle, "Of course my love"
Tony reaches up and begins to unbutton the rest of Steve's shirt till he is able to pull it open revealing his full chest, pert nipples and rounded stomach pushing up against his abs. Tony drops a kiss onto the mound saying 'hello' to their pup, Steve smiles and runs his hands through Tony's dark hair. Next Tony moves to Steve's sweat pants and pats Steve's hip once to lift up so he can pull them and his shorts down over his hips and down his legs his scent and slick pours out of him causing Tony to growl.
Tony reaches for a pillow from the couch placing it on the floor, "on your knees Omega" Tony orders.
Tony helps Steve move off the couch and onto the pillow not wanting him to lose his balance and fall before removing his jeans and shorts and sitting himself on the couch legs spread.
"Come here love, your Alpha has something for you" Tony coos down to Steve as he strokes his hard shaft. Steve moves to sit in between Tony's legs; resting his head on Ton's inner thigh before opening his mouth and sinking down on Tony's cock till his nose is buried in his soft curls around the base.
"That's right baby, take all of your Alpha inside you" Tony moans as Steve begins sucking and licking all around Tony's engorged shaft before starting an easy up and down rhythm making Tony hiss in pleasure.
"Oh god Steve" Tony moans as he gently runs his hands through Steve's soft blonde hair that has grown out a bit long but Tony loves it.
Steve pulls off Tony's cock and looks up at him with pleading eyes "Alpha"
Tony sits up so he can lean down and kisses Steve's pouty lips, "alright love back on the couch, on your back love so I can play with your little nubs"
Steve lets out a sigh of relief, he loves giving oral to Tony but being on his knees even with the pillow is becoming uncomfortable the further along he gets.
"Thank you Alpha" Steve remembers to say as Tony again helps Steve up off the floor and lays him back onto the couch, his head propped up with a pillow as Tony crawls in between Steve's slick covered thighs. Tony leans forward keeping his weight off of Steve's stomach and wraps his lips around one of Steve's nipples pulling it deep into his mouth causing Steve to arch is back and moan while Tony's other hand flicks and pulls on the other.
"Oh god Tony….Alpha so good" Steve whimpers as his hands reach behind his head fisting the pillow.
Tony moves over and attaches himself to the other one slowly going back and forth pulling moans and hisses from his Omega. Tony pulls back and kisses Steve forcefully on the lips, with tongues twisting around each other and teeth nipping before pulling away to kiss his way down Steve's chest and bump before sitting up once more looking at his Omega.
"God love, you look so good with your dark nipples hard and straining, lips kiss swollen, our precious pup protected inside of your belly, this beautiful cock hard and leaking and your slicked up hole just waiting for me, for your Alpha to fill you up" Tony coos to Steve as he runs his hands gently over his lover making Steve's body arch and writhe begging for his Alpha.
"Alpha please, please need you" Steve cries arching his hips towards Tony.
Tony slowly begins to work 2 fingers into Steve's wet and sloppy hole, spreading them to help stretch Steve causing him to let out a deep moan as his hands return to his nipples, rotating and plucking at them. Then Tony adds a third finger and begins thrusting them in and out as he searches for his lovers prostate and watches his Omega moan and arch his back in pleasure.
"Tony….Alpha inside please please" Steve begs giving his nipple a twist.
Tony removes his fingers giving his stiff cock a quick stoke before spreading Steve's legs just a bit more so he can fit as close to him as possible. Tony takes his cock in hand already noticing his knot is present at his base and begins to slowly push into Steve's slick opening till he has bottomed out and feels another gush of slick being released, his Omega's body doing everything it can to ease his entry making sure both are pleasured.
"Oh god ALPHA…..so full" Steve sobs as he feels Tony bottom out and his inner walls suck him deeply inside.
Tony reaches down and rubs their baby bump before reaching for both of Steve's hands with his own giving them a tight squeeze, "Easy love, just breathe"
Tony pulls his hips back leaving Steve practically empty, making him whine before Tony thrusts forward as deep as he could, Steve gasps as his eyes roll back. Tony loves watching Steve's reactions during their love making; he's so open and unguarded but only for his Alpha.
Tony has worked himself into a firm but deep rhythm, leaving Steve gasping his hands fisting the couch cushions below him as Tony continues to rock into him. Both men now covered in a film of sweat as the sounds of vigorous fucking echoes around the room.
Tony pushes Steve's legs up a to his chest leaving his weeping cock and baby bump beautifully framed between his legs for Tony to admire while he watches Steve's sloppy hole continue to take his cock, his knot is so close to popping.
"Your Alpha is going to fill you up babe, going to knot you solid, you ready for that my Omega, you want your Alpha's knot?" Tony purrs down to Steve who is writhing begging for the knot as Tony had found his prostate and has been constantly hammering into it.
"Yes….Alpha…knot me….ah ah fill me up….please please" Steve begs as he releases a sob feeling the knot trying to push past his rim with every forceful thrust of Tony's hips.
"Almost love….you can take it I know you can….gonna fill you so full" Tony pants giving one last thrust till his knot sinks in tightly.
Steve cries out, "ALPHA!" as he explodes onto his round belly, his eyes roll back and the sound of the couch cushion ripping from Steve's grip. Tony's release pulses deep inside of Steve's flexing walls as they will now be connected to each other for close to an hour before his knot will release them.
"Oh god Tony, so full" Steve moans as he feels another gush released from Tony.
"Mmmm" Tony groans out as Steve flexes his inner walls around Tony again as he releases another spurt of come.
Tony carefully tries to maneuver himself so he's not placing all his weight on Steve's belly but can still have access to Steve's nipples to play with while they wait out his knot. Once that is figured out with some awkward moving of limbs, huffs and chuckles, Tony latches onto one of Steve's nipples and begins to suckle while playing with the other causing Steve to moan and flex down on Tony's cock again making release another load, Steve is beyond full.
"Alpha, feels so good" Steve moans as Tony suckles deeply at his breast hoping to help stimulate Steve's lactation ducts, something Steve has been reading about in the baby books. Tony moves to the other nipple and continues on much to Steve's enjoyment.
"Alpha takes such good came of his Omega" Steve mummers running his fingers through Tony's hair feeling so relaxed at the moment filled with his Alpha's cock and knot that is still occasionally releasing spurts inside of him. His pup is safe and content and his nipples are receiving extra attention, god he could stay like this for hours.
Eventually Tony's knot did deflate enough that he was able to gently pull out of Steve with only a slight hiss of discomfort that quickly turned into a gasp as Tony slid a large 8 inch beaded plug into Steve's still gaping hole to keep all of his Alpha's seed inside.
"Alpha" Steve whined but his body remained submissive and his eyes closed until he feels clamps being clipped to his tender and throbbing nipples.
"Oh god….Tony….what" Steve's eyes fly open and looks down at his chest as he lets out a pained whine.
"You are going to be my good Omega aren't you love and where your Alpha's toys" Tony cooed at Steve as he rubs the pad of his finger across one of Steve's now clamped nipple.
"Ah ah ah ah ah….Alpha…..yes Alpha...oh god...thank you Alpha, thank you" Steve sobs out tilting his head to show his bonding mark to his Alpha.
"Good boy….such a good Omega….I'm so proud of you" Tony tells Steve causing him to preen and arch his back showing off his chest to Tony making him chuckle as he leans down to kiss Steve's pouty lips and then move over to lick and nip at their bond mark, mixing their scents.
Tony convinced Steve to take a warm bath with him so Tony could wash him down and then ordered him to remain naked for the rest of the night which consisted of ordering pizza and watching movies with Steve and Tony cuddled up on the couch with a blanket, every so often Tony would reach down and work over one of Steve's nipples, as he lets out a deep moan and clenches down on the length of beads.
By bed time, Steve was begging for his Alpha's cock again but before Tony gave in he placed a cock ring around Steve's leaking shaft and left the clamps on for the remainder of the night making Steve sleep with them on.
Tony filled Steve up again with is cock and knot then plugged him up for the night. Tony woke several times that evening to a moaning and writhing Omega but offered only his Alpha cock to nurse on till morning when Tony removed the clamps, cock ring and beads and knotted Steve again much to Steve's relief after begging his Alpha for it.
Steve was so sensitive and overwhelmed he cried and sobbed in pleasure till he was settled on his Alpha's knot once more, letting out a deep sigh much to Tony's amusement and pleasure.
As the months past and Steve's belly grew the love making had to become more inventive much to Tony's and Steve's delight. Steve was now producing milk in his last month which Tony nursed from with great excitement. In the last month it became much more difficult to maneuver Steve's now bulging belly around, so Tony kept Steve constantly filled with toys of some kind. Steve told him being full helps keep him calm and he can still fuck him with the toy while he sucks on his cock.
