Marion was still sore in the anal region and was bent over the edge of her bed wondering how soon the rest period would come to an end. She thought with a wry smile that it might well come to her end , again. She had been fucked, fisted and flogged in the past few days and she was uncertain if she could take much more of this behavior without more sexual pleasure and less outright pain. " Marion , we are going to let you get off the bed and walk around or go to the toilet if you need to." Don advised her. She got up and entered her bathroom and sat on the commode for a moment, the feeling had been that she needed to empty her bladder and perhaps her bowel. She soon found that the latter was just the result of having the entire hand up her backside and not actually because of the need to evacuate her bowel. She stood and went to the sink and washed her hands and returned to the bedroom where Lyle and Don awaited her. "We are going to fuck you at the same time. Lyle likes to assfuck and I'll go into your pussy. I'll get on the bed and you can get on top of me and lower yourself onto my cock. After you have me up your pussy Lyle will get on the bed and he'll get up your ass." Don mapped out the next events for her. Marion was about to tell the two men to pack it up and get the hell out of her apartment when she realized that the instructions were in keeping with what she had agreed to as serving as slave to the men that Don introduced her to. She didn't want to give up entirely the contact with the men and felt obliged to go along with the dual fucking as planned. She was sure that if her ass was not too sore that it might even be somewhat pleasurable as she had not been taken in both lower openings at the same time as far as she was aware. She had taken two men orally and vaginally at the same time but never one in the cunt and another in the ass. Don got onto the bed after taking off all of his clothes and stretched out on his back. His penis began to erect as he looked at Marion standing beside the bed, her naked vulva giving her the look of an untouched girl. She climbed up on the bed and straddled Don as he lay on the bed his erection now full. She pulled the lips of her vulva apart as she slowly lowered herself to the glans of Don's shaft. The smooth acorn shaped tip of his penis felt very inviting as she sank a little onto the organ. She lifted herself and lowered slowly until she began to lubricate enough to allow the entire penis to enter her. She leaned forward, her breasts touching Don's chest as she let the weight of her torso fall on him. The position, her chest on his and her legs spread to each side of his hips left the cheeks of the buttocks gaping and the anus exposed to the air and to the gaze of Lyle. Lyle looked at the coupled pair and as he took off his clothes he too became fully erect. He mounted the bed and took up his place behind Marion. He noted that as she raised and lowered herself, that Don's cock was moist and glistening. He put his hand to Marion's vagina and wet his exploring fingers and then spread the moisture onto the glans of his penis and to the brown ring of Marion's exposed anus. He continued to spread moisture over the inviting dimpled circle and then inserted the tip of his index finger to assure that the anal canal was going to allow him entry without too much difficulty. Marion was pumping at a furious rate, breathing rapidly and in a shallow manner, well on the way to orgasm. She sucked in a very deep breath as she felt Lyle's hardness in her bottom. She was sure that the two men could feel the presence of each other through the thin wall of tissue separating the two cocks. She felt a level of arousal that had not been her experience in the past, and she was moaning in pleasure at a decibel level that would have rivaled a rock group. Don and Lyle were making their own contributions to the noise level with various groans, appeals to various dieties and to their mothers. The writhing threesome carried on the dual intercourse for several minutes until there was no holding back nature. With strong contractions of the various muscles and glands Don came inside the warm wetness of Marion's vagina. Seconds later a similar response filled her rectum with the warm outpouring of Lyle. The two men stayed inside until the limpness of their pricks would no longer allow retention in the cavity that had so recently given such friction to the thrusting organ. As Lyle came out of the anal opening, Marion was free to move from her position athwart Don. The men told Marion to rest if she wished while they took showers to cleanse the sweat of the exercise from their bodies. Marion asked to be allowed to shower before either of the men and was quite surprised to get an affirmative answer. She was only a short time in the warm shower, rinsing some of the remnants of the recent action from herself. She stepped out of the shower to find Don and Lyle standing at the bathroom door, their cocks hanging down in the limp posture of post intercourse. "While Lyle has his shower, I'll have some things for you to do Marion." Don said in a soft voice. " Let's go back to the bed and have you on your back for starters." he added. Marion was unsure what was to happen next as she stretched out at full length on her back. " Pull your legs up to your chest and grab your ankles. I'm going to put a bar between your knees to keep them as far apart as possible." Don said as he left the room for a moment. He returned with a broom from the kitchen and placed the handle between Marion's legs. He then took some of her panty hose from the drawer of her dresser and used them as rope to tie her ankles and wrists together and to anchor the broom handle to her knees. The finished job had Marion trussed in an extremely revealing position. With the broom handle keeping her legs apart and the knees flexed to her abdomen, her vagina was open to the inspection of both Lyle and Don and below the shaven pussy was the still partially opened anus. Both aperatures were moist from the semen still oozing from them and glistened in the light from the ceiling fixture. " Here is something to keep you from feeling empty Marion," said Don as he placed a very large dildo in her vagina, " and Lyle has something to occupy his favorite hole as well." Marion was certain that another dildo was going to be inserted into her anus and she tensed in expectation, and was suddenly sore as the hard plastic thrust through the tightly shut ring into her rectum. She was once again filled in both lower openings and she was more than a little embarrassed to be so widely open and exposed to the stares of the men who now stood at the sides of the bed and admired the bound and plugged young woman. " The picture needs something to complete it ." mused Don as he looked at the scene. " I know, it needs something on the tits even though they are nearly out of the picture because of the bent knees and the arms at the side of the chest." he added and he left the room to return with a pair of nipple clamps in his hands. " These should do the trick Lyle, I will just stick them on her and she'll be done as well as can be." Don predicted as he fastened the clamps to each of her nipples. Marion let out a soft cry at the touch of the first clamp to her right breast and a louder cry as the stiff spring of the clamp contracted on her left. Lyle looked at the results and thought that there was still some room for improvement in the tableau. He too went out of the room and came back with a black rubber ball gag, which he deftly pressed into Marion's mouth and fastened the strap behind her head to hold the ball tightly between her lips. Both men pushed on the dildos and then pulled them almost out, repeating the movements several times with each. Marion was moaning, and seemed to be some attempt to say something, but was totally unable with the ball in her mouth. Don and Lyle found the increased moaning and the accompanying shaking of the head as she tried to speak, quite amusing and kept the dildos moving to keep things going for several minutes. They decided that the time to end the scene was near and they removed the dildos at the same time and before Marion was able to show any reaction they took out the gag. " That was very cruel, to excite me with the two dildos and to keep me from saying anything with that awful gag." Marion said with some considerable feeling. " It was meant to be cruel Marion, that was the purpose of us coming to your apartment. We were not aiming to please you but rather to please us, and it pleased us to do those things." Don told her as he and Lyle moved to the door and readied themselves to depart. Dbiang
