Man up! There is a sexy lady in there that needs your help!

With a deep sigh John picked up his spirit and guts before opening the door. Trying to be as graceful and careful as possible, his eyes were lowered to the floor as he quickly moved into the room and closed it again. With lead in his shoes he scurried towards his desk, where the lady now would be standing, dripping wet in only lingerie. As he got close, his curiosity got the better of him and **** his eyes to shoot upwards for a quick peek.
That quick peek became a much longer peek as he was surprised to find that her skirt was in fact still on, despite of her pleading that he had to come in himself because it had already been removed from her hips. "You lied." He proclaimed brusquely.
"How?" Her reply came just as swift.
"You begged me to come in because your skirt was off, or whatever. But what do I see now on your hips?" John asked trying to regain control of the situation with a bit of a coy attitude.
She smiled in response. "Oh sorry, my dear John. I just thought you needed some incentive to come in here and knew my naked butt cheeks would do that for you... I have seen you looking all these months!" Her eyes sparkled with teasing looks.
John raised his shoulders. "Well you got your towels now. I will better be off and leave you to it."
He said as he started to turn away. Only halfway in his turn she grabbed his shirt at his chest with one hand. "Do not leave now, John. I was hoping I could repay you for lending me this office and bringing me the towels." She pleaded.
John his curiosity was still pondering about what kind of payment she had in mind when she pushed him towards the desk to lean on. "I would not mind if you just stayed to watch, sweetheart. I guess it is not fair for me to throw you out at this point, after I teased you all this time with my looks." She smiled.
John tried to stammer a reply, about how wrong this would look like if someone would come in, but she started to slightly move away. As her hands reached down to the waistband of her skirt, his mind was already too preoccupied to think of the quite reasonable chance they would get caught and the repercussions of such a drama. All he could do was watch as she pushed her thumbs underneath the band and started to pull it down.
As her back was turned his eyes wondered across her back, along the strap of her bra and down her spine. His eyes were focused on her lower back that seemed to flex a bit as the skirt started to travel downwards in a crawling pace. Then, the top line of her panties became visible and more and more of her firm butt were revealed to him. The lace panties fitted superbly on the rounding of her ass and accentuated this marvelous example of physical sculpting. As the skirt hits the floor, John saw this young girl completely bend over in lace lingerie and wet from top to bottom. His loins started to stir with excitement and the member in his pants grew harder with every passing second.
She looked back at him with a huge seductive smile as she lifted her feet one at a time to pull the skirt from underneath. She then turned around slowly, doing a full 540 degree turn so that he had time to look her entire body up before she stood there facing him with the front, perky as ever.
"Like what you see, boss?" She asked. John tried to reply, but his breath seemed to be stuck in his throat.
"Very nice," He stammered, "you must do a lot of working out to get in such shape?"
She smiled "Why, thank you, John! That is so nice of you to say!" Gently she picked up her long, wet hairs and tucked them behind her right ear, revealing more of her neck. John his eyes immediately got fixated on her cheekbone, the soft looking skin of her neck and down to her collarbone and firm breast below.
She caught him looking and replied accordingly. "I do a lot of workouts for my butt and tummy." She spoke as her hands grazed her butt, across her hips, crossed the lacy waistband of her panties and then higher across her belly. "But not everything can be perfected with a workout, you know. Some things you just have to be given by nature itself." She continued as her hand met up with the underline of her bra. Her left hand cupped the underside of her left boob while the index finger of her right hand grazed along the edges of the cup of her bra. For a moment she stood there, as if she was conflicted.

"Pull it out." She suddenly blurted. John was confused; half getting the idea of what she mend, but also half shocked by a seemingly outrageous suggestion. "Pull what out?" He stammered.
"Pull your dick out." She now spoke in a more decisive and calm fashion, even though her cheeks started to color a red shade. "It obviously is liking what you are seeing now, so pull it out to give it some room. That is how I will be able to repay you."
For a moment John contemplated whether he should be polite and tell her that his office was a public space and that he would not need rent to have women change clothes there. But he could immediately see that refusing would not make her and himself happier in the end. The wager of whether anyone would enter or not was already completely banished minutes ago and the deeper he went down the rabbit hole, the easier it seemed for him to completely forgo his morals. He was not thinking about the lock on the door, let alone his wife back home who would not be pleased to have her husband pulling out his member for a 23 year old, half-naked, blond girl.
His hands went down to the button of his jeans and the zipper flew down just as quickly. Before long his right hand pulled down the elastic while his left hand grabbed his member to release it from the cage of fabric. Immediately his already stiff penis stood erect towards the girl, who seemed completely focused on his dick. John knew he did not have an exaggeratedly big or thick cock, but anyhow Sarah seemed to be all taken in by it. 'She probably just has not really seen a stiff one in quite some time.' He thought to himself.
As she came back to her senses, her right hand traveled further up and took the strap of her bra between the fingers. As she moved it down over her shoulder to her lowered elbow, she spoke more softly. "Please stroke it for me. Enjoy my body with your eyes and fantasize about making love to me. Wank that cock as if it was inside me and I will give you a bit of a show." Her right hand had let go of the strap and was now gently folding the right cup of her slightly rigid lace bra, showing more and more of the breast in the process. John could see the edges of her areola, which fulfilled him with such an urge that made his heart seem to jump. Instinctively his hand reached for his member and grabbed it over the full width. Slowly it began to make pumping motions as his eyes were fixated on her breast.
Her left hand now traveled up and began lowering the other strap, also folding in the left cup of her bra. Just before her breasts were fully exposed, she twirled around, showing her back. She looked back over her shoulder with a smile, picking up sexual energy from watching him stroke his dick up and down. On the tip of his penis a small drop of pre-cum started to form from his excitement and she looked hungrily at it.
He watched as her upper shoulder twisted with the movements of her arms that reached back for the clasp of her bra. In seconds the lingerie gave way and dropped onto the floor, now showing a completely uncovered back. John so desperately wanted to touch her warm, probably silky-smooth skin and to press his body against the profile of her back. His naked member squeezing against the fabric of her panties between her butt cheeks. But he resisted the urges and instead slightly increased the pace at which his hand was pumping along his cock. She saw him taking her back in completely and decided to increase the wager a bit by only gradually turning her torso. This way he could see her backside still completely while the profile outline of her right boob complemented the picture. After such a sight, John was definitely feeling the heat and slowly started to notice the build-up deep inside him.
Then, Sarah stuck her thumbs underneath the waistband of her panties and proceeded to also sliding them down. As she got lower and lower, her body bend more and more forward. Even though she had her legs close together, the gap underneath her butt was wide enough to give him a royal view of the lips of her vagina and the small darker circle of her anus. For a short while she stood there while John was staring with wide eyes and his hand working furiously on his member. She then stepped out of her panties with one foot, turned around and placed her other foot on his desk next to him. The panties still dangling on her ankle.
Surprised by her flexible and intrusive move, John tried to get it all in his mind. There she was, her legs parted and her labia completely exposed from the front. His eyes darted from this special place between her hips, to up her torso where he could now finally see her perky breasts completely exposed. The nipples in the middle of her dark brown areolas looked to be all stiff and inviting to welcome his lips. This sight alone could very well compete for his interest against her slightly opening pussy lips below.
"Can you help me there, babe?" She asked him?
John grabbed the fabric of the panties with his free hand and watched how she withdrew her foot from it. She walked a bit back towards the towels on the far side of the desk and left him standing there; cock in one hand and her wet panties in the other.
Sarah grabbed a towel, moved towards him and sat down on the edge. Once more she placed her feet up on the desk chair, exposing herself fully to him. With a tremendously slow pace she started to rub herself dry with the towel, starting at her feet up to her upper thigh. Meanwhile her perky breasts were dangling free in the air, following here every moment without fault.
John watched as she moved up one leg and down the other, then using the towel to dry between her thighs, softly sighing as she rubbed along her labia down to her anus and back along the sides and flicking across her clit. Here after she continued to dry her torso, a bit more swifter now to cover the longer distances. She then stood up and proceeded to stand next to John, the side of her leg touching his and her breasts pressing softly against his shoulder.

"Still not done, sweetheart?" She asked provocatively. "Are you getting there?"
John replied by nodding, as the proximity of her naked flesh gave him even more incentive to blow his load across his office floor. "OK, just let me help you, because I just have to get dressed and to work now, John!" She said briskly to tease him.
John let out a large sigh as her left hand reached in and grabbed his member by the tip. Immediately his own hand let go and searched for support on the desk as he leaned back. His mind seemed to explode as her touch felt like setting of millions of sensitive connections in his cock.
"Fuck, I am going to come soon." He stammered and Sarah looked around. "I cannot have you come all over the room, babe, let alone my body."
"Just get the towel then." John replied, slightly agitated as he wanted her to stroke him to completion.
"I know something much better." Sarah smiled as she picked up her panties from the desk. "I got a spare set to change into and this way I can take the evidence away from here." She spoke. "We do not want the laundry service to notice that you come into your towels now-and-then, right?"
John could not reply as he was to busy feeling that she had folded the fabric of her panties over the tip of his dick. The soft feeling along with her firm grip gave him goosebumps all over and as he felt her fingers move slowly over the ridge of his cock head he was almost completely zoned out. "Let us move up the pace a bit more. I want you to fill my panties, John. Come all over my pussy stained panties."
Sarah needed not to motivate him to come, but John felt even more excited after the dirty words reached his ear. The thought of his cock pressing up to the panties covered in her girl juices, along with a final forceful stroke along the shaft of his dick finally made him contract the muscles in his pelvis to shoot out thick ropes of come into her lingerie. He closed his eyes to picture her bending over with her ass exposed to him to get the max out of the feeling as he felt Sarah press her body against him even firmer.
As soon as the feeling of his climax had became more softer inside, he opened his eyes to look at her. There she was, standing close to him, her head not 10 inches apart from his. Her lips invitingly slightly opened as she watched her hand still working slowly on his cock. Without really knowing why, he bend slightly forward as trying to kiss her. Suddenly she turned her head and backed away a bit.

"John, please... You are a married man! We cannot kiss." She said in a mocking way, as she pulled the panties of his dick. "Not here anyway..."
John looked at her winking at him as she walked to the place where her bag laid on the floor. Again she bend down to pick it up, the quick view of her ass making John his tired cock twitch.
She placed the bag on his desk and opened it to pull out her fresh underwear. Then she opened the old panties a bit to look down on what John had produced and carefully folded it into a ball.
"I might not even wash them before I wear them again next time, John." She softly spoke as she pulled the new underwear on in quick fashion. "Somehow the thought of having your cum stains pressed against my pussy lips feels so enticing to me." She continued as she looked at him, putting on the new blue bra.
She caught his raised eyebrow and continued. "Do not worry, hun. I use birth control... I just like the fact that you will be looking at me every day, trying to figure out whether I am wearing this pair and getting all wet by the thought of our fluids mixing down there." She smiled deviously. "Maybe one day I will let you check what underwear I am wearing and you will find out they are still there and filled with your delicious spunk."
John let out a large sigh as he tucked his cock back into his pants, unsure as to whether he was happy about what monster seemed to be unleashed now. Then he watched as how Sarah put on fresh jeans and a small top with a deep collar and let his mind-eye drift back to her perfect naked breasts.
She walked up to him and gave him a kiss on the cheek. "Thank you for being so accommodating, John. Honestly I wanted to try you out for some time and you have not disappointed me."
Sarah started to move towards the door of his office. Just before she got there she turned around.
"We will talk about next time. I really hope there will be a next time."
And with that she walked away, leaving a dazed John behind in his office. Only the drops of water that remained lying on the floor seemed prove of what sexy acts had transpired in what seemed to be an all-normal day.
