A day went by since the last challenge. The girls (Terra and Cindy) decided to combine their challenge, just as Marte and Ryan had done. Terra called Marte and alerted her that they were on their way up the mountain and would arrive in 20 minutes. Terra informed Marte of the situation and told her it would involve Marte and Ryan. Marte asked for details, but Terra declined, stating she would fill them in when they arrived.
Terra hung up the phone and let out a long laugh. "They thought they got the best of us yesterday, they are in for one hell of a day."
Cindy smiled, "We are ingenious. I cannot believe how well this worked out."
"About yesterday..." Terra spoke after a few minutes of silence. "It was great. I was shocked when you grabbed me by the head and kissed me. That is not like you."
Cindy looked over at Terra and winked. "You were breathing so heavy and turning me on so much. I couldn't help myself. Your hand was driving me crazy as it sat on my lap. I needed more of you. I needed to taste those sweet lips of yours."
"You and Marte are my best friends I could ever have. Thank you Cindy. To be honest, I needed that too. I am still so horny though. Today isn't going to help."
Cindy just laughed as she steered her SUV to the left and began driving down the stone drive way. She parked to the right side of the stone driveway and put the vehicle in park. They jumped out and headed up Marte's wooden steps. Terra opened the screen door, handing it to Cindy and turned the knob to the storm door. The girls entered the living room where Ryan and Marte were cuddled on the couch, watching television.
Terra and Cindy walked across the living room and stopped at the hallway entrance. Marte saw a wide grin on the girls' face and knew they had cooked up something good. She wrapped her arms around Ryan's waist and prepared for the news.
Terra cleared her throat and set the stage for the challenge. "This challenge involves the two of you. Cindy and I are going to give you two instructions. The challenge is for you two to have sex the way we instruct you to."
Marte felt her insides beginning to twist. Why did they always have to give her a challenge that pushed her to the limits. She had played in front of the two girls, had sex multiple times with Terra and done all sorts of playing with them, but she had never had sex with another person while they watched. Terra could see the look of shock on Marte and Ryan's face. She knew this would be one for the ages.
Cindy finished the rules of the challenge. "We will tell you which positions to be in and tell you what actions to do. Neither of you are allowed to have an orgasm until we say you can."
Marte spoke up. "I am not sure I am okay with this you two."
Terra retorted, "You do have the right to refuse. You will not be able to refuse the second challenge though. You know how are minds work. Are you sure you want to take that chance?"
Ryan turned to Marte and said, "Whatever you want to do hon. I will do it if you okay it."
Marte thought long and hard. She had visions of Terra demanding her to be whipped and tormented after the last challenge the two girls had endured in public. She thought of the alternative and knew the girls had devious minds. Not wanting to take the chance of something much worse, she reluctantly agree.
Terra instructed them to move to Marte's bedroom and strip. Marte and Ryan stood up and headed for the bedroom, Marte holding Ryan's hand. Ryan could feel Marte's hands shaking. He put his arm around her and tried to console her briefly. Terra and Cindy were just steps behind them.
After a few moments, Marte and Ryan were naked. Terra instructed Ryan to get on the bed and lie on his back. His penis was already semi-hard. Terra instructed Marte to climb on the bed and get in the 69 position. Marte glared at Terra and slowly climbed onto the bed. She turned towards Terra and Cindy and straddled Ryan's face. Marte could feel her pussy tingle with anticipation of the pleasure it was moments from receiving. Marte took a deep breath and leaned forward, placing her elbows on the bed on each side of Ryan's knees.
Terra instructed them to begin orally pleasuring each other. Marte slowly lowered her hips and gasp as her labia were touched by Ryan's wet, warm tongue. His tongue circled her outer lips, circling them twice before splitting her lips gently and sliding up her vagina. Marte grabbed the base of Ryan's penis and slowly wrapped her lips around the tip of his meat. She began bobbing her head a few inches, taking the first couple inches of his penis into her mouth. She could feel the heat radiating off his manhood. She felt Ryan moan against her pussy. She rolled her hips and slid her clit toward his tongue.
Marte found herself enjoying his tongue and occasionally forgetting to participate. She ran her tongue up and down the length of his penis before wrapping her lips around him again and sliding her mouth as far down his manhood as she could handle. She felt his hips raise and push his penis a bit further down her throat. She released a whimper as he slowly teased her clit with his tongue.
Terra and Cindy had taken a seat on the love seat in the corner of the room and were enjoying this live display. Terra sat with her right arm around Cindy's shoulder. She could not take her eyes off them. She loved seeing Ryan's penis glisten with saliva as Marte slid her mouth up him. She glanced down to see Marte's small breasts sway as she moved.
