Turkey and all the trimming; a marvelous day with sister and all her family; visions of the perfect holiday that danced in my head. My sister, Emma and I had always been close so why should it be any different now. I loved my sister and her daughters. To me that was as it should be.
When we were young my pa was on the road a lot and I was left as the boss at home. There was just ma, Emma and me so while ma was busy looking after the place my sister and I hung out together.
We used to play a game like I was pa and she was ma or doctor and patient. When we became teenagers it was innocent enough but by our later teens it was an established habit. About this time we were developing a sexual appetite and didn't understand it. Other schoolmates frightened us but we were very comfortable together so I think it was natural we should experiment among ourselves.
I remember when Emma turned eighteen we planned to consummate our relationship by finally having sex. We knew by then it was a taboo relationship so we had to be secret about it. We met in a tree house my pa had built us years ago.
Emma was pretty mature by then with wondrous perfectly round breasts and a kinky fuzz of hair around her cunt. We were about the same height like twins except we were a year apart. She had come to me for advise on dating so we were quite intimate with each other.
We had talked for over a year about maybe having sex so she felt she was ready and she preferred me to do it since I was reliable and ready. We had watched each other masturbate and even helped each other prior to this so it was a natural progression. The only hang up we had was secrecy. We were both afraid someone might find out about us and I think that was what held us up so long before trying it.
I woke with the usual woody and rushed to the bathroom. Emma slipped in behind me. She whispered, "Has father gone?"
"I just woke up. I don't know. Have you heard anyone moving around yet? Is mom making breakfast?" I added, "Happy birthday, Em."
She smiled a secret evil smile my way, "I think it will be." She shivered. "I better go and see who is about." She slipped away as I showered and got around for the day.
"Are you going to be much longer?" It was dad's sister, Aunt Fern calling. She was visiting with her son, Garvey. He was a chubby preteen and a pain in the ass. He was always wining about something and his mother was always screaming at him to quiet down (or shut up). They were sleeping in the guest room but had to use our bathroom.
"Be right out, auntie. Has dad gone in to work yet?"
"I don't know. I suppose he has since it's so late."
I left the bathroom in my robe and she quickly went inside. I slipped on pants and slippers with a T shirt then ran downstairs. I saw Emma speaking with mom in the kitchen so I ducked on into the breakfast nook. I put my gift with the others on the side counter.
"Did you get me anything?" It was Garvey. I looked a glare at him and shook my head.
He started to whine, "How come? Why didn't you get me anything? He didn't get me anything." he squealed to his mother as she came into the room.
"Shut up! Be quiet now." she shushed him.
"But he didn't get me anything." he whined. His mother glared at him and raised her hand. He said no more but ducked away.
Mom came in with coffee for aunt Fern and Emma was with her. Auntie called out, "Happy Birthday, Emma. Now you're a adult woman. What do you think about that?"
Emma just shrugged her shoulders and smiled at them. Our aunt went on, "Do you have a boy friend yet, young lady? You beware those sneaky dogs that will try to take advantage of you." Emma just shook her head continuing to smile. I grinned as she noticed me.
"Happy Birthday, sis." I said for effect since no one knew we had spoken earlier. I nodded at the gifts, "Looks like you didn't get a car." We laughed together. "If you got a guy he's an awfully small one." We joined hands and laughed at the joke while the adults looked on and Garvey tried to make sense of it all.
"You didn't get anything for me." he whined rather quietly.
After breakfast Aunt Fern and her prodigy went to do some shopping so Emma helped mom with the dishes then sought me out. She whispered to me nervously, "Do you want to go to my bedroom or yours?"
I felt myself getting hard already as I whispered back. "Em, are you sure about this? It must be hard for you since they say it's painful for a girl the first time."
"You heard Auntie Fern. I'm an adult woman now so I can decide and I choose you. I know you will be careful and not hurt me any more than you can help. I trust you, Chuck, and I want you to be the one."
"Have you got any rags to clean up with in your room?"
She thinks for a moment, "Old panties or if I wash them an old towel or two. What do you think?"
"I think it's better than anything I might have. Your room it is then. Let's go." Now he's excited.
"What if mom comes upstairs?"
"She doesn't usually. You're just nervous."
She grins, "Of course I am. What do you think? I don't do this every day, you know."
"But we will." Charlie is emphatic. "It's just the two of us now. It has to be for a while. I'm sure we'll find partners one day but for now it's just us. Right?"
"I don't want anyone else. Just you." She turns away, "My room then." She leaves and I watch her move. Her hips swivel as she advances a foot then swivels back as the other foot moves. In my mind I can see the flexing of her vagina and her vaginal lips as her weight shifts. So many times we have helped each other masturbate and I never tire of the movements of her body and the smell of her.
I check that mom is busy putting together dinner then drift towards the stairs to follow her. In my mind I am not as decided as I let on to her. If we do it we can't undo it and I'm not sure I can pull out of her fast enough. What if we have a baby? She will never trust me again and it's a real risk. It's scary when you come right down to it. Then everyone would know and we'd be cursed... perhaps even by our parents.
I headed up the stairs preoccupied by my thoughts but high and hard on hormones. I muttered under my breath, "Just treat this like we are going to masturbate each other. We've done that and it worked out terrific. This will too and I know how to make her cum over and over so she will like it, I'm sure." and "I just have to remember to pull out as soon as I feel that tickle in my nuts. I must do that."
At her door I hesitate. I rap lightly with my fingers. "Are you ready?" My cock is pushing my pants straight out in front of me. "I sure am!"
She opens the door with a big grin looking down at me, "You sure are! Come in here!" She pulls me in. "Remember to go easy. It's so big it will take time to get it in. Oh Chuck, we are going to do it, aren't we?"
I hold her in my arms and grind my cock into her stomach through our clothes, "I promise to take it easy, sis. If you say to stop I will right away, too. Don't you worry, Em." We drift still holding each other towards the bed. "Do you have an old towel to put under us?"
"By the bed there. I'll spread it under us. Where do you want me to lay?" She is nervously biting her lip. She turns away and picks up the old towel. As she's spreading it on the bed the door flies open.
"What are you guys doing up here?" comes the whine.
I spun on the little pervert and said, "If I was you I wouldn't snoop in other people's rooms because they just might break your arm off and beat you with it." I stamped a foot on the floor towards him and he disappeared. I said to Emma, "Looks like they are home. I guess we better not do anything now. Maybe tonight, sis."
She looked disappointed, "Okay, I think you're right." She placed a hand on my boner, "Be patient, big fellow." She turned away and put the towel in a basket.
We had a light lunch then ma asked us if we wanted to go visit in town with them. It was friends of Aunt Fern they were visiting so we said not today. We would work on homework for school or just watch TV. Since they planned to celebrate Emma's turning of age tonight when dad was home to join us that gave us the afternoon to while away. We saw new possibilities.
When they left I said, "Shall we retire to yon bedroom, my dear?"
"Dost thou have a modest yardarm for me, kind sir?"
"It's growing as I speak." I laughed as it poked out in front of me.
"Oh, I shalt swoon full away." she passed her hand in front of her forehead and made like she was passing out.
"Now as long as someone else doesn't come by to wish you birthday greetings or they don't come home unexpectedly we should be able to have some fun."
"We'll just hide in the bedroom and not answer the door or the phone."
