A week later, Heather found herself bored with studying and being horny from playing with her nipples, she took out an extremely large rubber dildo and began to rub it over her breasts and twat through her underwear. She got hotter immediately and locked the door. She turned out the lights and peeled off the rest of her clothes and got a large bottle of oil from the dresser and rubbed her tender, bouncing tits and heavily lubricated the dong. It was one of those things that she had discovered in a sleazy store in a back alley taking a short cut one day. A porn shop, but what a great collection of stuff. Her nipples were already standing up and tingling and jiggling as she pulled an overstuffed chair over near the window and looked out over the campus. One hand was stroking and pulling one nipple out to its maximum length, tingles going down between her legs as she felt her belly tightening from the lust building in her twat. It was time to give herself a good fuck. The dong was a monster, a bulbous, ribbed head and thick shaft over fourteen inches long. It was a special dark rubber that felt and flexed very much like a real cock, and included a tank of oil that could be heated and shot into her pussy as she came. Sitting back with her legs spread wide over the arms of the chair, she began rubbing it up and down her slit, the oil mixed with the cum pouring from her. Her legs twitching from the excitement, the top of the head finally lodged slightly in the entrance. She began pushing in increasing strength and more of the head pushed her open, but it was too big to go in. Her passion was rising from the thrusting and she pushed harder and harder, beginning to roll the long shaft in circles. Little by little, her breathing now becoming more a pant, her need steadily expanding, the head penetrated rib-by-rib and then, popped inside with a loud pop. "Oh!" It was more a grunt. "Give it to me! Give it to me you big fat sucker. Fuck mamma like she needs it so bad tonight. Ahhhhh. Goooooodd", she whispered breathlessly. In seconds, she would come. Her hand pumped it deeper into her, now six inches. She felt her belly tighten and release was near. Her head arched back as her body went into reflex action. A shudder went down her arching spine. As her hand stroked the obscene thickness of the shaft, it was working itself inside, inch-by-inch, up into her pussy, now stretched to what seemed like the breaking point. The stretched skin at the base of her clit were causing explosions of heat hich were passing out through her nerves and setting her mind on fire with passion. Legs over the wings of the chair, now almost straight, twat stuffed full beyond belief, she humped against the thrusts inside. Her hips were twitching and thrusting more and more on their own as she began to go over the edge. A rhythm established itself. Her head rolled back against the chair and she gave herself totally to it. "Ohhhhhhh. Unnnnnn. Ummmm... mmmm... mmmmm Nmmmm..MMMMMMM... MMMMMMM!" Over eight inches were inside and she felt full beyond belief but wanted to take it all. Her hand was working with increasing speed as the shaft slid up and down her hole, her extended clit rubbing over the ribbed shaft. In seconds, she would come for the first time. She always climaxed multiple times, but her need for release from this first one was so great as it rushed toward her. A sudden soft knock on the door broke through and intruded on her passion. Summing all her willpower, she stopped the thrusting, the shaft still buried as deep inside as she could take it. She was completely breathless, tits swollen from her passion, nipples extended, hands shaking, sweat on her forehead. She was hanging on the very verge of a massive orgasm and the slightest twitch would set her off. The dong was twitching like a real cock from the pulses in her twat, sticking obscenely into the air, the tip jerking in spasms. The knock repeated a little louder. "Yes, who is it?" It took her a moment to make her voice sound even. Even then, it was thick with lust. "It's Traci, your art teacher. Have you got a minute?" Please go away, I need to come, she thought. Shit. "Yes, ah, just a minute. I was just changing." Her nerves still on fire with the need to come, she eased the fat dildo out and quickly covered it with the corner of the blanket on her bed. Her insides complained and she ached to mount the monster again, but, she tossed her underwear in a drawer and pulled on her T-shirt and jeans. Still breathing hard and face flushed, she flicked on the lights and opened the door. "Hi, can I come in? I'm not coming at a bad time, am I?" "No. No. Please come in. Excuse the mess." Traci closed the door behind her. "We need to talk, Heather." Heather waited. Traci was staring at her still rigid nipples. Her pussy was still on fire. Traci was getting hot just looking at this beautiful set of obviously erotic tits, unfettered by any bra. "Um, about what's been happening. I've never, I mean, I don't.." She was losing her train of thought. She walked over and sat on Heather's bed, her knees weak. Heather realized she was only inches away from the fat dong under the covers. Traci tried again. "I know you and I have had some, well, unique very personal experiences but I want you to know that I really do respect you and hope you do me and that.." Her hand had moved the cover and the head of the dildo was exposed. Surprised to feel the hard, wet object under her hand, she looked down. Heather was blushing slightly when she looked up. So she was getting herself off when she knocked on the door. That explained the nipples and red face, Traci thought. Traci pulled the shaft from under the cover and was amazed at the size of it, easily twice anything she had ever seen, much less used. "My God. It's huge!" Her voice was an astonished whisper. "Do you, I mean, you are so slight.." Her fingers traced the ribs on the head and upper shaft, designed to pull on the flesh and add to the sensations of a deep fuck. A deep fuck. Her mind drifted to thoughts of... "Yes, I use it, sometimes when I'm really horny. I was using it when you knocked." Heather was staring boldly at her. Traci knew in a moment she was telling the truth. It was still warm and slick with cum and oil in places. "Aren't you afraid it will hurt you?" She was holding it up, surprised at the girth and feel. So much like a real cock, but so very much larger. "If you're careful to start it slowly, then you eventually stretch out and from then on it's great. Really great. It really fills you up. At first, I used to come before I could get it in, it took so long, but now I get eager and pop it right in." It was quiet for a few moments and Traci continued to run her fingers over the ribbed head as her thoughts continued to think about getting fucked with this wondrous tool. Heather said, "Would you like to try it?" The little talk she wanted to have was quickly being forgotten. All her thoughts were on how this monster might feel inside her. She almost groaned out loud. Startled by the bold suggestion, she said, "I'd never get that inside me. I'm too small." She was running her fingers wonderingly up and down the shaft and over the huge head. Her pussy was already wet just thinking about the head, pushing in on her and spreading... "I'll help you if you like. It just takes patience and a lot of oil." "We really can't. I came tonight... I mean, what if someone were to..." "Look, I know we get each other hot. Let's face it, we really get off on each other. I don't know if that's good or bad. I enjoy sex and I take it you do as well. So let's enjoy and not sweat the small stuff. I'll stop being such a bitch in class. I hope I didn't get you in trouble." They looked at each other and Heather came over and took the long shaft from her. She locked the door again and killed the lights. Traci sat for a moment, but Heather came over and reached down and unsnapped her jeans. Traci pulled them down and shed her underwear. Heather directed her to lay down and put two pillows under her ass. Pouring oil all over her pussy, she began gently rubbing it into the folds and between the lips. Traci gave a gently groan and trembled as the big-chested coed ran her fingers into her and out. She was hot instantly to fuck. Her pussy blossomed like a flower as the passion built. Finally, soaking the shaft with oil, she placed the head in Traci's opening and began to rotate it and push gently. "Don't hurt me. Ohhh... It's so big. I can feel myself stretching out. That feels so good." Heather was stroking her clit to keep her relaxed and opened up. The pressure was increased and she rolled it back and forth. Only the top third was going in. The stroking increased and Traci's hips were lifting slightly as her rigid clit responded to the constant stimulus of the stretching skin. "I don't think it's going to work. Gooooood. Ohhhh. Mmmmmmm. Harder. Push a little harder." The head was now half in and Heather pushed and stoked. Traci was almost ready to come from all the stimulation. Her pussy was stretched further than anything she could imagine before tonight. Gripping the edge of the bed, her head was tossing back and forth as she started to loss more and control. It was beginning to hurt a little, but the pleasure was intense. "Ohhhh... Fuck, me. Heather fuck me with it. I need it sooooo bad. Fuck. Yes. Yes. YES!!!" She was shouting now. Heather reached over and stuffed her underpants into her mouth as she continued to groan and shout. The head was almost in and she leaned on the end with her hand and it popped inside her how stretched inner lips. Traci lurched and spasmed below the waist. She was stretched beyond the breaking point, but suddenly felt no pain. This great mother of a cock was driving her crazy, her insides invaded like nothing she had ever imagined. Heather poured more oil down the shaft and pumped it into Traci, a half inch at a time, slowly moving the bulbous head up inside her, six inches, now seven. The ribs pulled and pushed the taught wall of the vagina, every nerve reacting, giving her sensations she couldn't even figure out. "Oh. I'm going to come. I'm coming. coming... argggghhhhhhHHHH" She screamed into the panties. Out of control, she was groaning as the passion started to drive her up toward orgasm. The orgasm she felt piling up just kept building, not releasing. Eight inches. Heather's arm twisted the shaft and pumped it smoothly in and out, in and out. Her own pussy twitched and throbbed with need to be fucked again with this great tool. "OhhhhhHHHHHh. MMMMMmmmnnnNNNNNNn." Nine inches. In, out. In, out. Each time, a little deeper. Traci now felt as though her pussy would explode from the pressure and stretching. The nerves deep in her body were sending shock waves to her brain. Out of control, lust took her and her nerves rolled her over the top. Her breathing stopped and she shook as stars exploded in her brain. Ten inches. In and out. Waves of passion rippling up her belly, in seconds, she came again, a wave of white heat exploding in her brain. Eleven inches. The head pressed into the top of her cervix and could go no further without true damage. It wiggled and moved in and out. Heather was amazed at how much Traci could take. Another explosive orgasm. Only the now wet underwear in her mouth was holding back the shouts and groans. The smell of hot, randy pussy filled the room like the hot musk of a heavy, sweet perfume. The pace of the pumping increased and, her handing gripping Heather's arm in a tight grip, she grunted and came one last time, back bent and tail now completely off the bed. Heather seized the opportunity and slid a long oil slick finger smoothly into her asshole, rolling it up until it was rubbing the thick dong through the tissue. It increased her pleasure and she shook and trembled and blacked out. When she came to moments later, Heather started slowly backing the dong out until the head was at the entrance, pulling on the lips, trying to break free but trapped at the entrance, then back up inside. Traci had never felt so full. In moments, the heat began to build again in her pussy and ass as Heather's finger rolled around and around. In less than five minutes, whimpering and crying out, she groaned wildly and came again, bucking against the hard rubber. No cock had ever done this for her. It had her in it's grip and she gave herself completely to it's assault on her cunt. She finally settled down and Heather helped her clean up and loaned her some underwear, which was pulled very tight across her wider hips. She left, still dazed from her experience, her pussy was tingling and stretched, a memory of a great cock still impressed on the walls of her pussy. She paused in the doorway, her face thick with lust. Heather said, "I'm glad we had this little, ah, talk. Come again sometime!" They both smiled. Heather locked the door, peeled her clothes and sank the dong, still soaked with Traci's come, deep into her pussy. As she watched Traci walk back toward her class building, her delayed orgasm was building. She rocked in the chair and began to groan and whimper, cunt pouring cum around the thick shaft. Traci, looked back over her shoulder and could see the girl in the window, rocking deep in the shadow of the window in the chair, unnoticeable to anyone not looking directly at her. Her own pussy tingled at the thought of that long fat dong now up Heather's twat. As she stared, Heather appeared to come, her head jerking from side to side, then back, mouth open. In spite of just having many multiple orgasms herself, as she walked up the hill, she was hot again.
