The next morning, Dan awoke wondering if it was a dream he'd had when he heard the words. "I want to have your baby". He looked beside him to see Leanne sleeping peacefully. He moved closer to her and then he felt it. He had a raging hard-on already and nothing to arouse him. He laid beside her for a little while and he just decided to wake her and see if she'd like to help him out a little. "Leanne? Wake up. It's morning." Dan said. "Hmm?...Dan?" she replied. "What do you want?" "I've got a surprise for you, that is if you want to help me?" he said. "Mmm...help you? What's in it for me?" She asked turning over to face him. Dan pulled the covers back to show her his rock hard cock. She looked down, then back up at him and smiled. She didn't say a word. She moved down and took it into her mouth. She deep throated him a couple of times and then worked on the head of his cock. "Oh...Leanne." Dan moaned. "That feels so good." "Mmm..." Leanne murmured. She started to play with his balls for a few minutes. It sent sensations through Dan. Then, Leanne stopped everything. "Fuck me." she said. "What?" Dan asked. "I said, fuck me." She turned around and got on all fours and stuck her ass out in the air. It was too much for Dan. He jumped up and got behind her, pulled her closer to him and guided his member into her wanting pussy. He pushed in slowly and pulled out just to the tip and pushed in again. He worked up to a good pace. "Oh...Oh....Oh..." Leanne began to say. "Harder, Dan. Harder." He listened to her and began to go not only harder, but faster. He could hear his balls slapping against her. "Uh..uhh...oh...oh..mmm" she moaned. "Oh yeah...you like it, don't you?" Dan said."Oh yeah. I love it, Dan. I want more. So much more!" Dan pushed in and out a few more times and then pulled out. "Do you want to try something different?" "Like what?" "Anal?.." Leanne was quiet for a few minutes. "I don't know..." she said. "Come on baby. We've done everything else. I bet you'll like it." She thought for a few more minutes and finally answered. "Okay." Dan smiled. "Let me get some lube. It'll be a tight fit." He reached over to his nightstand and pulled out a bottle of lube and squirted some in his hand and lubed his cock and then put some on her tight asshole. It puckered up a little then relaxex. "I'm going to use my fingers at first so you can get used to the sensation." he said. "Okay." Leanne said. He began by putting one finger in and working it. It was a tight fit, but then he worked in another finger. He used two fingers for a while then he thought she might be ready. He pulled his fingers out and put his cock on the opening of her asshole. "Just relax. Don't think about the pain or the tightness. Relax now." he told her. Leanne took a few deep breaths and relaxed herself. She thought about different things. Dan began to push his cock into her. Then he heard a pop. The head of his cock was inside. It was already too much for him, but he made himself hold back. He pushed in further, then stopped. "Are you okay, Leanne?" "I'm...I'm okay. It's really tight." she said lightly. Dan continued to push in and the he pulled out and pushed in again. He picked up pace and held onto Leanne's hips. Leanne began to moan. "Ohh....Dan...Oh...ohh..ohhh." "uhhhh...ohhh...ohhhh...." he moaned with her. Leanne pushed back into Dan letting him go all the way into her ass. She then reached to her pussy and began to play with her clit and finger herself. "Oooohh..."she cooed. Dan decided to reach one hand under her and grab one of her breasts and play with it. He squeezed her nipple gently and rubbed it. "ohh....uhh..." Leanne moaned. "Leanne," Dan said, "I can't hold off any longer. I'm gonna blow." And he did. String after string of his hot cum shot into his sister's ass. "Uhhhh...." he moaned. After his orgasm subsided, he pulled and rolled over to lay down. Leanne laid down beside him, her ass dripping with his cum. "Dan, I love you so much. You make me so happy." Leanne said. "I love you too Leanne. You make me happy as well." He reached over and kissed her hard. He let his tongue slip into her mouth, massaging her tongue with his. She invited back by letting her tongue slip into his mouth enjoying the same sensations. They ended their make-out session with a nap in his bed. The next three weeks became a blur for the two. They fucked as much as they could before their parents came back home, but when the parents were home, both Leanne and Dan kept to themselves. It wasn't until Leanne noticed that she was late for her period, did she ask Dan to her room to talk after their parents had left for a party. "Dan...I've got something to tell you. It's serious." she said. "What?" he asked. "Well...I'm late." she said. "Late? Late for what?" he asked. She gave him a serious look and it hit him. "Are you kidding me? You're...you're...." he began stuttering. "Yeah...I think I'm pregnant. I wanted to have a baby, but not this soon." she said. "Oh, Leanne..I love you. But how can we break this to Mom and Dad? We can't lie to them." "Oh, shit! I forgot about that. We are going to be in such deep shit if they find out, Dan. I...I...I can lie to them! I can tell them I was with this guy at school. A one night stand....that we did use protection, but the condom broke. I'm sure they'll buy it." she said. She began crying. "Leanne, baby. Don't cry. It'll all be okay. I promise. I'll take care of you. I'll take care of the baby." he told her. "B-b-but how?" she asked him. Dan thought for a minute and he decided to ask her. He dropped to one knee and took her hand and asked, "Leanne, will you marry me?" Leanne became quiet. Tears still running down her cheeks, all she could do was nod her head yes. She smiled and kissed him. She pulled him onto her bed and pulled her top off revealing no bra, just her bare breasts. Dan pulled one to his mouth and kissed it. He then kissed her other breast. He then began kissing down her body until he reached her pants. He undid them and pulled them off along with her panties. He could already smell the sweet aroma from her pussy. He wanted to fuck her right there. But he held back. He stood up for a few minutes and undressed. He got back onto the bed and asked Leanne to spread her legs. She did so without objection. Dan situated his-self between her legs and put the head of his cock to her pussy. He pushed in slowly and felt the head of his cock slide in without objection. He felt her hands slide along his back, down to his ass and grip tightly, and loosen. Leanne then moved her hands back up slowly. He leaned in to kiss her, and then sucked one of her lips into his mouth and gently nibbled on it. Dan pulled away for a moment and looked down at this beautiful creature he had known for nearly his whole life that he was now making love to. The beautiful creature that was going to have his baby. His thoughts brought him back to what he was doing. He looked at Leanne again. She was smiling at him. "What were you thinking of, Dan?" she asked. "Just you and the baby. Our baby." "That sounds perfect. Our baby." All the while, Dan was still pumping into his sister's hot pussy. She started moaning his name. He new she was going to hit an orgasm sometime soon. "Oh Dan....Dan....Ohh....harder..harder...Dan..." He did so. He began to pump harder. He could hear his balls slap against her. Leanne then wrapped her legs around him and pulled him closer to her so he could go further into her. "Oh yes...oh..oh..uhhmm.. " Leanne moaned. "Ughh...ohh...oh yeah..." Dan moaned aloud. "Oh Dan....I love you, Dan. Uhh..oh.." Then Leanne got the urge to be on top. She told Dan to get off and lay down. When he did, she straddled him and lowered herself down onto his hot throbbing cock. "Mmm...." she mewed. She began to grind her hips into his groin, making sure every inch was in her. She started to bounce up and down on his cock enjoying every minute of it. She tilted her head back with her eyes closed. "Ohh....mmm...uhhh....." "Oh..god...Leanne..that feels so good." Leanne smiled. She bent down to kiss Dan, but instead, teased him with kisses around his neck. She sucked on a place for a little while and left him a 'love bite' just for show. Leanne kept up riding his cock until she felt her pussy begin to quiver and tighten around his throbbing member, "Dan...I'm going to cum" she said. She kept riding hard until she knew it was the precise moment and thrust her self down and let go. Spasms went through her body like it was her first orgasm. Dan was just on the urge to cum. He grabbed her hips and held her down, even though she was done. He pushed up into her and let string after gooey string of his hot cum shoot into her wanting pussy. He didn't let her up until his every last drop was spent. He finally let her get off of him and she laid next to him with her head on his shoulder. "That was the best yet. You were amazing, Leanne." Dan whispered before falling asleep. Leanne was already asleep before he said it.. But she knew how he felt, because she felt the same.
