For Susan, the night before this new session was a long and hard one, she was in a constant state of arousal, and her pussy was soaked as she thought constantly about Dr. Wood's words, "The ideal gangbang should last at least four to five hours!"
Eventually, the time had come for Paul and Susan to go to sport's clinic. They arrived exactly at 2 p.m. Susan wore her short red mini-skirt with a white top, the top was so deliberately tight and difficult to put on so she had to remove her bra to get it on, The fabric was so sheer and thin you could see her big areole and big large hard nipples, even their color, quite clearly, Her huge breasts swayed back and forwards through the clingy material with every motion she made, It was an incredibly sexy top. To complete the look, she wore a pair of four-inch red heels.
"Wow! Susan! You look amazing!" Dr. Clark praised her. He couldn't believe how hot Paul's wife looked.
"Yes, Mrs. Fisher is the naughty girl," Dr. Wood nodded her sneaky smile and asked, "Are you ready, hottie?"
"Yes, I am ready, I have not stopped thinking about their... cocks all night, and all morning," Susan answered shyly.
"Great! Now, we get to meet our guys," Dr. Wood said with satisfaction.
At that very moment, Erik and Greg entered the room. Susan felt disappointed, the meeting wasn't panning out the way she expected,
"But... you promised... and I was expecting four or five men," Susan said sadly, "I missed my morning session and I really need... you know..."
"Don't worry hottie, I know very well what you need, your other participants are waiting, in the next room. They are all handsome well endowed young men, who enjoy sex, they all have incredible sexual power, impressive erections, and I am sure, they will satisfy you beyond your wildest dreams. However, the truth is I need your help Susan, here we have seven studs and I don't want to choose for you... I want you to do that, and next to Greg and Erik you choose an additional two or three lovers you would like for yourself from the remaining men!" Dr. Wood said.
The smile returned to Susan's face, "Can I see them?" she asked innocently.
"Of course," Dr. Clark said as he went to the curtain mounted along the wall.
As Susan waited, she saw Dr. Clark slide the curtain open a little. There was a full glass behind, giving Susan a partial view inside the adjoining room, obviously used for special cases. It was a small but lavish room, complete with a king-size bed. Dr. Clark opened the curtains fully and Susan could see seven naked young men in their twenties who were standing next to each other adjacent to the bed.
"Ooh my!" Susan took a few seconds to react and pull herself away from the erotic sight.
"Don't worry Susan, this is a one-way mirror, they can't see us," Dr. Clark continued after a short pause to allow Susan to take in the sight and comprehended what she was seeing.
Susan was thrilled! The young studs were all handsome and extremely well endowed. Among them, she recognized her earlier lovers, Tom and Pol. But, for the first time, among the young studs were and three black men.
"All of our studs are tested for STD's and all the studs are hung 9 to 12 inches," Dr. Clark announced proudly.
Then Dr. Wood gave a description of each of the studs stating their number, age, erect cock size, its length and girth. After all the introductions were made, Dr. Wood said, "Let's go Susan, tell us who you have chosen."
After a few minutes of looking them over Susan knew it was going to be difficult to choose between them. She realized Dr. Wood had made it incredibly difficult, making her choose!
"I don't know... It is so difficult for me... All of them are so handsome with nice big cocks,! I need your help Dr. Wood," Susan said obviously overwhelmed.
"Do not worry hottie. I'm here to help you," Dr. Wood smiled and gave her support immediately in the form of a supportive squeeze of her hand. Then she continued, "First, take it easy. Second, tell me which one of these handsome men would you like and why?"
"So... Maybe number 3, Tom ... I know him," Susan said shyly.
"Yes, that is a good reason, You have already enjoyed sex with him. Who is next?" Dr. Wood said as she praised her.
"Number 1, Pol... for the same reason," Susan answered.
"Ok, that's great. Who is the next lover?" Dr. Wood encouraged her.
"Err... number 7, he is so handsome, muscular and... immense," Susan said. She could see what a giant he was, his arms were ripped, his chest was wide and thick. "And he is... he is black!" Susan added shyly.
"Have you ever had sex with a black man Susan?" Dr. Wood asked.
"No. I have fantasized about it but I never have," Susan answered blushing.
"It's okay Susan, there is no need to be ashamed. Now you can fulfill that fantasy. Look, no less important, is his cock, how dark, black, thick, long and uncircumcised it is. That's the right choice for you, Susan," Dr. Wood said.
"Also, your hubby will like the contrast of your bodies next to each other," Dr. Clark added.
"Yes, the contrast of her smooth white skin against his black skin will amazing to her hubby. Who is the next lover, Susan?" Dr. Wood asked.
"Number 2. He is handsome, as well... and he has such fat cock," Susan explained feeling confused.
"Yes, number 2 has the thicker cock even thicker than Greg's. I know you love a fat cock most of all, so we sought all of these for you to enjoy," Dr. Wood said looking very pleased.
"But, he is incredibly fat..." Paul said worriedly.
"Do not worry, hubby. Your wife has proven she has the ability to handle great girth as well as length! This is exactly what she need's, big fat cock that can stretch her hungry pussy," Dr. Clark answered.
"Next Susan?" Dr. Wood asked.
"Number 5. The black guy, I like his black skin and... his beautiful huge black cock," Susan said.
"I agree with you, Susan. You should definitely be having more intercourse with black men," Dr. Wood confirmed.
Susan continued, "Number 4, he has huge testicles! His balls were as large as..."
"As billiard balls," Dr. Wood finished the sentence instead of Susan. "You could see the fleshy sac holding his oversized testicles swaying loosely behind his large manhood. That's great for you, you need a lot of sperm and I am sure his huge testicles will produce a large amount of sperm. If you take him I promise you will be become absolutely fascinated by his ejaculations. You will see how much and how far he can squirt." Dr. Wood explained.
"One alone! Number 6. He is a black also with a really long cock. It seems longer than other!" Dr. Clark tried to help.
"Yes," Susan immediately agreed and looked at Dr. Wood.
"Well, what's your choice," Dr. Wood asked.
Susan pondered the question. Obviously, this was a difficult choice, Erik moved behind her and rested his hands on her hips, pressing his big erect cock against her.
"You're all hot, Mrs. Fisher!" Erik whispered into her ear as his hands caressed her hips. He slowly slid his hands up her body until he cupped her heavy breasts, causing her to take a deep sharp breath and pant.
"Um... uh..." Susan couldn't think or talk, because now she felt Erik teasing her neck by kissing it and breathing on it.
"Do you want all these men?" he asked her as he slid his right hand down over her abdomen until it rested right over her skirt-covered crotch. He then traced his hand down her leg, under her mini-skirt, and slowly ran it back up her naked thigh until he touched her soaked panties, full of her swollen sticky pussy!
"Um... uh...I don't know, it is so difficult to choose," Susan answered breathlessly.
"I'm sure you want, you need and crave what these men can give you to win," Erik continued to persuade her.
"I don't know, it is so difficult," Susan repeated.
"A choice has to be made, Susan," Dr. Wood noticed as she smiled.
"Well, it seems like Susan can't make up her own mind. We'll have to do it for her. We'll pick all the guys!" Dr. Clark decided.
"What do you think, hottie?" Dr. Wood asked Susan, while looking at her lust filled face.
Erik continued to tease and caress Susan, she was out of her mind. "Um... uh... if you say so... yes," she answered as Erik felt her move her hips slightly in rhythm with his fingers.
