You heard him inhale and groan right outside your door and you damn near moaned out loud but managed to bite your bottom lip hard enough to almost draw blood as you heard him speak. "Oh shit, doll, I could smell your slick all the way upstairs!" He groaned and you could hear him dragging his nails down the wooden frame of the door as he kept talking.

"Open the door for me, darling and I'll make it all better, Alpha promises." He growled through the door and suddenly his scent was must stronger and you knew he was standing outside your door with his cock in his hand, I mean how else would his scent have gone from tolerable to overwhelming in a matter of moments? You whimpered and slid two fingers deep inside yourself and began to pump them slowly in and out as you tried not to slick all over again as you thought about what he could do to you with those hands, that mouth ... that cock.

"That delicious smell of yours is stronger now. You're about to slick without me in there, aren't you? Such a naughty Omega. I'll have to punish you for that." Steve groaned through the door and you could hear him beginning to pant and you knew that he was about to leave a mess outside your door that either he or you were going to have to explain and then clean up in the morning. "Steve!" You whimpered as you started to gush around your fingers the ecstasy of the orgasm only lasting a few moments before you were writhing in agony again and the heat flared hotter this time causing you to whimper as you crawled to the edge of the bed and stood up in order to get the soaking wet sheets off your bed.

"Sugar, let me in." Steve begged softly and it took everything in your power to ignore his scent that smelled like leather, rain, and musk. It took you a few minutes to stagger over to the dresser where you kept the clean linens and get a new set out and then stagger back over to your bed and pull the dirty, soaked ones off and put the new ones on. The entire time that you were changing your bed you could hear Steve still pleasuring himself right outside your door all the while begging and pleading for you to let him in. You'd finally gotten the top sheet on when you heard him gasp and you knew exactly what had just happened, not only because you heard him when he'd came but also because the amount of pheromones he'd released caused you to hit your knees moaning his name.

It was quiet for a few moments and then all of a sudden you heard a very odd sound, until you realized what he was doing and another hot gush of slick coated the insides of your thighs. The low scratching sound that was coming from your doorway was him dragging his nails down the wooden frame repeatedly until you heard him hiss in pain and speak again. "You and that heavenly smelling cunt of yours just made me make a mess, doll. But don't worry, I've left a mark to let all the other Alpha's in this building know that you...are mine. But just know, little one, there will come a time when I won't be able to stand out here and control myself as well as I've done tonight. There will come a time when I kick in this adorable piece of cardboard that Stark calls a door in and that's when I'll take you properly. Now finishing slicking for your Alpha." He growled darkly as you reached between your legs and teased your clit until you once again had slick gushing from between your legs. "Good girl, (Y/N)." He said quietly and you'd thought he'd left until you managed to climb back up onto the bed after throwing a towel over the mess you'd just made and you heard him speak one final time.

"Get some sleep, baby doll." You laughed softly to yourself as you heard him stalk away knowing full well that sleep wasn't something that you was going to get until you called Banner back down to administer another shot. "FRIDAY?" You panted as the heat returned in spades and you almost started crying. "Doctor Banner is already on his way, Miss (Y/L/N)." The AI said sympathetically. You felt bad for not being able to say thank you but about the time you'd opened your mouth one of the worst cramps you'd ever experienced had slowly worked it's way through your abdomen and you screamed about the time Bruce and Natasha came running through the door.

"Shhh, shhhh! It's ok, it's ok sweetheart." Natasha said as she jumped in bed with you and immediately pulled you into a hug as the tears started and Banner worked fast to get the syringe filled with the medicine. "This is a new type of medicine that I'd actually been working on for the last few months. It's the same time of medicine as before only this is the extra strength version so hopefully this will be able to last much longer than the regular stuff for you." He said as he walked over with an alcohol pad and the syringe already in hand.

You hugged Natasha tightly as you felt him swab your hip with the alcohol pad and flinched when he gave you the shot but then almost immediately began to relax as you felt yourself begin to cool off significantly. You'd just started to doze off when you heard Natasha say, "Before you get some well earned rest ....uhhh.... do you know who left their mark on your door outside?" Without even opening your eyes you smiled and softly said, "Steve." You could've sworn you heard them both say, "Oh shit," before you passed out but you were too tired to even care.
