Nat and Bruce

Nat had a large gash on the back of her leg making it hard to walk. Steve and Sam propped her up between them and helped her to the medical lab. Bruce was standing next to one of the beds waiting for them.

Bruce smiled at them as they walked in. "Hey Guys. Right over here." He points to the bed. "I'll get you patched up.

Nat gives him a small smile and jumps up onto the bed with Steve's help. Steve and Sam both say goodbye and make a quick retreat.

Bruce walks over to her slowly. "Lay back, I need to get your pants off, so I can stitch up your leg."

Nat gives him a coy smile. "Oh, yes doctor." She lays back and slowly unbuttons her pants without breaking eye contact.

Bruce swallows and looks off to the side. "Nat, I...I really want that but first, I need to take care of your leg." He leans down and takes off both her boots and then helps her remove her pants. "Lay down on your stomach. It'll let me have the best access to your leg."

Nat looks over her shoulder at him as she rolls over, making sure that her ass sticks up a little bit before she lays completely down. "Is this how you want me?"

Bruce just quietly stares at her for a second, and then shakes himself. "Um... yea. It's a pretty big gash. I'm going to give you a Novocain shot before I start."

Bruce prepares the shot and turns back to her. "You'll feel a small pinch." When he was done, he sat on the stool next to her preparing the sutures and disinfectant supplies. "Once you're numb, I'll start. It's pretty deep."

Nat looks at him. Even though her leg hurts like a bitch, Nat can't help but think that he's so sexy when he's in serious doctor mode. "Did you give me enough to last for a while?"

Bruce looks over at her, "I gave you enough that you shouldn't feel anything until tomorrow morning."

Nat smiles and patiently waits while he patches her up. He puts the supplies on the tray when he's done. He gets up and walks behind Nat, like he's inspecting his work. In reality, he's staring at her perfect ass. He can't help himself and he grabs her ass roughly with both hands giving both cheeks a hard squeeze.

Nat gasps at the sudden, rough contact. She looks over her shoulder and smiles as she pushes her ass backward into his hands. He gives another hard squeeze and then leans into her, licking her center through her underwear.

Nat moans and pushes back into Bruce. He gives her ass a slap causing her to gasp. "Roll over."

Nat does what he asks. He slowly and carefully removes her panties before burying his head in between her legs. He uses his mouth and fingers to bring her to the edge of her high. He lifts his head and looks up at her writhing on the bed. He slowly climbs over her and presses a kiss to her lips and then kisses down her neck as her hands scratch his back. "Nat, are you sure you're up for this? I know that I started...I..."

Nat pulls him back down to her and reaches between their bodies grasping him through his pants. "Bruce, I want this, I need to feel after today." Their lips crash together and Bruce quickly sheds his pants.

He stops suddenly and pulls back. "Wait, we-"

Nat whimpers, "Bruce, please."

He chuckles slightly, "Don't worry, I'm not stopping but we can't do it like this because of your leg." He nips her ear. "You can be on top or you can get on your hands and knees. I don't want your stitches getting pulled."

She smiles suggestively at him as she rolls over onto her hands and knees while wiggling her ass at him. He smiles at her. He kisses her lower back and then slowly pushes himself into her tight heat.

She moans and pushes back against him, trying to take him faster. When he's fully sheathed he reaches around and starts to rub her clit. Nat gives a high pitched moan at his ministrations and bucks her hips. Nat meets Bruce's thrusts, moaning as he pushes her closer to the edge again. She could tell he was close, his thrusts were becoming erratic. He leaned down, his front to her back and changed the angle of his thrust, hitting her in just the right spot. She cried out as she felt her body tighten and convulse around him, just before he moaned out his release and grabbed her hips tight and holding her in place as he reaches his climax.

He kissed the back of her neck as he pulled out and helped her lay down. He held her for a few minutes, the two of them breathing quietly.

Nat sighs, "We should get dressed before anyone comes in."

Bruce chuckles, "I doubt anyone will but you're right."

They get up and get dressed, Bruce asking questions about the mission and Nat giving him answers. They head off toward their rooms, Bruce looks at Nat, before he can speak Nat quietly says, "After today, I think I just need some quiet time. This mission was rough."

Bruce smiles and gives her a hug and a kiss on the cheek. He knows and understands that while they seek physical comfort and can usually talk about anything, sometimes she just needs some space. He watches her walk away before turning into his room.
