5. The Challenge
Kelly knew she was being watched when she pulled into work. She retrieved her purse, her lunch, and her water bottle from the Explorer, closed the door, and started down the sidewalk to the front door of the building. She was half way to the building when the lights on a Honda Accord flashed when she stepped in front of it. She stopped, turned, and looked at the building. She heard someone knocking on glass and watched her reflection shake in the fifth window on the ground floor. 'So that's where he sits.' She turned and continued into the building.
Bob knew from the smirk Kelly had flashed at his office that she was in the mood to play. He completed his morning routine and headed for the john. Kelly was standing in the lobby of the building talking with a male coworker.
"What are you looking at, you big geek?" Her smile indicated that this was her idea of 'playful banter'.
"You know," Bob said as he smiled and walked around her into the restroom, "you keep parking your broom in the handicapped spot, you're going to get a ticket."
Kelly's jaw dropped in mock surprise. The smile in her eyes assured Bob that he had not pushed her too far.
Kelly pushed the door open and walked out into the sweltering heat of the day. She looked up and saw Bob sitting on the hood of his Honda. "Can I carry your books, little girl?"
Kelly stopped in front of him. "What makes you think I want you to?"
Bob stood up and held out his hand. "Because you didn't say 'no' immediately."
Kelly handed him her lunch bag and started looking for her keys as she headed for her car. "You're pretty confident. You better be sure your ass can cash the checks your mouth is writing."
Bob fell into step right beside Kelly. "Oh, I got all kind o' skills that you ain't seen yet."
Kelly unlocked her door and got in. "Oh fuck you."
"Your place is closest." Kelly turned and saw the challenge in Bob's eyes. He handed the lunch bag to her through the open door.
"Prove it." Bob sprinted to his car as Kelly barked her tires leaving the parking lot. Ten minutes later, he was sprinting up the walkway to her apartment. The door had been left open. He walked in and slammed the door behind him. Kelly was again standing in the middle of her living room. "Let's see what you got, looser!"
"Take your clothes off." He grabbed his button-down oxford at the center of his chest and, with one yank, sent buttons flying all over Kelly's apartment. "NOW!"
Kelly started removing her clothes quickly. "Oh. The big, strong man is gonna rip my clothes off." They were both naked quickly. Bob advanced on Kelly like he was hunting her. She backed against the wall, but the challenge on her face never wavered. "You gonna give me your best shot?"
Bob reached down and grabbed her left leg at the knee and picked her leg up. Kelly gave a little yelp as she reflexively reached out to his shoulders for balance. "Are you excited?" Bob's left hand went straight to her sex. "Let's see if you're ready. Oh, you're nice and wet, aren't you."
Kelly snaked a hand down and grabbed Bob's cock. "Is that all you got for me?" She stroked it softly. "You better bring your 'A' game today, buddy."
Bob slipped Kelly's knee up to his elbow and reached down to get her other leg. He hoisted her up off the floor and slid her down on his cock. With three strokes, he was completely buried inside her. Bob pinned her to the wall and began to pound her with all his might. Kelly started back with the verbal abuse through clenched teeth. "Give it to me! Give me that cock! You got nothin'!" Bob thrust into her relentlessly. He was able to stave off his impending orgasm by trying to knock her pictures off the wall. Bob fell into a rhythm as their bodies slammed together. "Is that all you got? Is that all you gah...ahh...AHH...AHH!" Kelly's nails sought blood as they dug into Bob's back. The added stimulation sent him over the edge as well. Bob grunted repeatedly as he filled her with his cum.
Bob released Kelly's right leg. His legs were shaking as he disengaged from her. He eased down on the floor, gulping air. Kelly sank to the floor and nuzzled Bob's neck. Bob finally managed, "How's...that?"
"Damn."
"Thank you. You're...amazing." They sat on the floor naked, trying to get their breathing back to normal. The silence was comfortable, not needing to be broken. Bob only spoke when the afterglow faded away. "I'd like to upgrade our relationship...if that's ok."
Kelly pulled back and looked at Bob's face. "What do you want to upgrade to?"
"Friends...with benefits...if that's ok?"
"You mean 'fuck-buddies'?" Bob was surprised at Kelly's frank language and the smile that crossed her face.
"I wouldn't have put it quite that way, but yes...essentially." Bob's face reddened.
"You're determined to take this slowly, aren't you?"
Bob rested his forehead against hers. "Yes, I am. I don't want to rush into anything, and I don't think you do either."
Kelly sighed, "You're right. You're right."
Bob stroked her cheek with the back of his hand. "If you want to change our relationship to something else, or leave it the way it is, just tell me, and I'll consider it."
Kelly shook her head and pulled back to look at him. Damn, why does he have to do that so well? "No. You're right. I just...I just feel like such a slut! I can't seem to keep my fucking hands off you!"
Bob smiled. "You're not a slut. You're just a kid with a new toy. Come on. It's 6:00. Let's go find something to eat."
They rose up off the floor and began searching for their clothes. Kelly did a quick mental check of what she had in the kitchen, and came up with a few things for one person, but nothing for two. "Uh, do you want to go out?"
