Steve and Nat were very excited about the engagement. Even if they hadn't really shown it in front of the others. They were happy, after all these years they were finally getting married. Steve had wanted to ask her in marriage for a while but they needed some important people to be there for their marriage and their relationship had remained a secret so they couldn't.
They walked down the hallway, holding hands, intertwining fingers, smiling. As they approached their room, they could feel some tension building between them. They looked into each other's eyes, feeling their heartbeat race higher. Before they got to the door, they were already kissing. Through all of those years, their love and passion for each other had only grown.
Steve pushed Nat against the door. They kept kissing while Nat tried to open the door. As she couldn't get it, Steve grabbed her by the waist with one arm, pulling her closer to him, so there was a free spot to reach the door handle with his other hand. They slowly walked into the bedroom, closed the door and started undressing each other.
Steve turned Nat, he slowly unzipped her dress, and kissed her neck. He pulled away from the kiss very slowly. She could feel his warm breath against her skin. She turned around, facing him and helped him out of his tie, jacket and shirt. For a few seconds she admired his muscular body. They looked into each other's eyes, for a little, they lightly smiled and kissed each other passionately.
Nat's dress finally fell to the ground, Steve picked her up and sat her down on their bed. He knelt down and started kissing her leg, up to her thigh and made his way slowly up with every kiss. Nat breathed heavier, Steve kept going, until she left out a soft moan. Steve stopped. He smiled and kissed her again, this time he went up from her belly to her neck. Nat ran her fingers through his hair, they were both breathing heavier. She kissed him, then turned him over, she was laying on top of him. She took the kissing slowly down from his chest to his abs and even lower everytime. He groaned in a very deep voice. Nat kept going for a bit, until he brought her back up and rolled on top of her. They laughed a little before getting back to business. They kissed passionately, letting their bodies express their joy, releasing their tension. Steve broke up the kiss only to kiss her shoulder, her collarbone and her neck. Nat moaned softly in his ear, as he went in deeper.
He kept going for a while. Their breathing synchronized. Their bodies became one, or at least that's how they felt it. Their heartbeat accelerated. They were both louder and louder as the time passed. They kept their private party going for a few hours and finally fell asleep cuddling.
