Part 2

She bit her lower lip and tried to fight back the pain. Tears leaked from the corners of her eyes. She hoped Jason didn't see them. If he did he might stop and she wanted to take this thing through to the end, no matter how much it hurt. She could feel every one of the twelve inches of his cock sliding into her. She hoped he didn't try to shove all of it in; she didn't know if her cunt was that deep.

She felt Jason's breath on her shoulder. He kissed the side of her neck.

"Does it hurt, Aunt Shannon?" he said. She sniffled and nodded. "Do you want me to stop?"

"No," she said quickly. "No. Don't take it out." He raised his head above hers and stared down into her eyes. God, how she wished he was just some other guy and she was ten years younger. She would marry him in this bed right now. "Fuck me, Jason. For God's sake, fuck me."

"Yes, Aunt Shannon," he said with a smirk. He drew his hips back and thrust them into her.

"Oh my God," Shannon cried. She put her arms around his neck and held on for a long, deep fucking.

There was nothing like being fucked by a man who had already spent himself, especially on another woman, even if it was the night before. He wouldn't be so anxious to get his own rocks off. She blushed with shame when she realized the other woman was her own niece. She never thought about sharing her secrets about fucking with her niece, since she had no idea she was already sexually active. However, if she was doing it with this stud three or four times a day, Katie probably knew a few things about fucking Shannon had not yet learned herself.

Then Shannon noticed most of the pain was gone, and she felt the incredible sensation of his thick cock sliding in and out of her wet hole. He was kissing her with tender touches of his lips on her neck and face and he was moving his hips up and down with a gentle but firm thrust.

Shannon wrapped her arms and legs around him and pulled him down tight. All of that huge cock was inside her. She'd fucked men more than twice Jason's age, men who were supposed to be experienced at fucking, who knew how to treat a woman to make up for their lack of size. Jason was not like them. He was better. He had the incredible size they would never have, and he had the tenderness they could only pretend to have. Here was her dream man, laying between her legs, fucking her the way she always wished she could be fucked, and he was her nephew. Tears rolled out of her eyes again as she held his head down to her shoulder, but this time they were from sadness.

She lost track of how long he was fucking her. It seemed like forever. She had an orgasm, thrashing madly beneath his strong body, digging her nails and her teeth into his shoulders and screaming at the tops of her lungs, then a second before she got what she wanted. His warm cum gushed into her and she cried, "Oh yes!" when she felt it. He grunted and his body spasmed and she squeezed him hard, milking his cock with her cunt for all the cum he had to give.

When he finished and the muscles of his body released their tension, he collapsed on top of her, churning his hips slowly back and forth. She held him tight and kissed his neck and shoulders. She could feel his cum squishing inside her and leaking out of her hole, running down to her asshole. That was where she wanted him next.

But did he have enough to keep going, or had he spent it all? He still felt hard inside her. But then, considering how much he stretched her cunt to get it in and how much it hurt, did she really want to go through that again in her asshole? Yes, she decided. That was what she wanted him to do to her the first time she saw his thing, and that was what she wanted him to do to her now.

She lifted his head and held it in both hands. "Do you and your sister fuck like this all the time?"

Jason blushed. "Not all the time. She has other guys she likes to fuck and I have girls I like to fuck, too."

"How did you turn my sweet little niece into a loving machine?"

Jason shrugged. "It just sort of happened."

They were quiet for a long time. She rubbed his back, enjoying the comfort of his warm, hard body on top of hers and his thick, hard cock sliding inside her like some alien creature.

"Do you still want to fuck my tail?" she said after a while.

Jason lifted his head. "Oh yeah. I forgot about that."

Shannon laughed. Jason lifted himself from between her legs.

"Roll over," he said, squeezing her ass.

Shannon rolled over on her hands and knees, lowered her head to the mattress and stuck her ass high in the air in his direction. Jason got off the bed and picked up Katie's overnight bag. Shannon looked back at him over her shoulder. He opened it and took out that blue tube of grease.

"Does Katie take that with her everywhere she goes?"

Jason shrugged. "She never knows when she might want it in the ass."

Shannon shook her head. "You kids today."

Jason's fingers touched her with the cold grease and she gasped. He smeared it over her asshole, poking his fingers in. She wiggled her ass and moaned. His fingers alone felt good. She tried not to think of how much his cock was going to hurt.

She thought back to the first time she took one in the tail. She was a freshman at college and met a guy at the football game. He took her to a party after the game and got her drunk and she didn't even notice when he got her naked in some bed. When he shoved his cock up her ass, she screamed in pain. He didn't stop, and fucked her until he came inside her. She was mad at him for days afterward, but when the pain went away, she realized how much she enjoyed it. From then on, she looked for guys who would give it to her in the tail. Most guys, she was surprised to learn, were not thrilled with the idea. Jason, however, seemed to be an expert.

The anticipation was killing her. She wanted him to just sink it in her and get off so it would be over. At the same time, she wanted him to go slow so she could savor every inch of that cock as it split her open. She wanted to enjoy the feeling of it wedged inside her tight hole, sliding in and out.

The bed shifted as he knelt behind her. She squeezed her eyes shut and tried not to whimper. She didn't want him to hear how scared she was.

Jason's hand touched her ass and she flinched. She was trembling. He probably knew how scared she was now. Would he stop? She thought not. He was probably used to girls being scared when he came near them with that thing. Did he ever fuck a girl when she said no? She couldn't imagine her nephew raping a girl.

"Spread your ass apart," Jason said. His voice was soft, just above a whisper.

Shannon reached back with both hands. Her heart was pounding and her breath was warm on the pillow. She couldn't believe she was actually going to do this with her nephew. Nothing was more intimate than being fucked in the ass. She found it created a kind of bond between her and the man who did it to her, and their relationship from that point could no longer be just casual. Now she would share that bond forever with her nephew. The thought made her feel warm and fuzzy inside.

She pulled her ass cheeks apart, trying to stretch her hole open as wide as she could. She was trembling all over. The cold head of Jason's cock touched her tender asshole. Shannon moaned. So far it felt good. Jason pressed it in and she resisted the urge to force it back out.

He pressed harder. She squirmed, biting her lip to keep from screaming in pain. He pressed more. A groan came from deep in her throat. It felt like he was trying to shove a tree into her ass. She remembered she was the one who asked for this. She began to regret it. The pain was intense.

Jason pushed for a few seconds, then eased off. The pain subsided. She was panting.

"Is it in?" she asked. Her voice trembled.

"Almost," he said. "You're still too tight."

She whimpered. It wasn't even in yet. She didn't know if she could take this. She must have been crazy to think she could take a cock that size in her tiny asshole. The pain to get just the tip in was too much for her already.

Jason started pushing again. Shannon groaned, her teeth clenched together. She could feel herself stretching to accept him. Jason's hands squeezed her hips and he forced himself in with a quick jerk. Shannon cried out, blinded by a jolt of pain. For a moment, she felt nothing but a sharp stinging, then the pain began to fade and she felt something else. Jason's cock was moving in and out, pushing a little deeper each time. Her insides were forced aside to accept his cock.
