The morning after the night before was a little strained,both myself and my sister were finding it difficult to make eye contact with each other,we said our good mornings and kept out of the way of each other,I kept thinking that we had both made a terrible mistake and now we were regretting it.
As the day wore on things seemed to lighten a little and we did manage to chat for a while, nothing about last night of course just idle chatter.
Mum wanted something from town and she asked Christine if she would go fetch it,she volunteered me to go with her.
The drive to town was almost completely in silence,but i knew someone had to say something about what happened so i broke the awkward silence.I didn't know how to start but somehow i did.
"Christine,about last night.''
She said nothing just glanced over at me.
''this is difficult,but we need to talk about last night,are we just gonna forget it ever happened?''
'' i suppose so Marty if that's what you think is best.''
This broke the ice and we began a gentle discussion about what we did,but more importantly we came to a decision about what if anything would happen next.
I explained i felt guilty about things and she said the same,but we both agreed that it was fun and we liked what we did and i very gently asked her if she would like to do it again. Christine looked embarrassed as she nodded and quietly said that she would. We didn't say much more until the return journey home,and this was when we decided that next Friday if we had the opportunity to,we would resume our late night fun.
The atmosphere seemed more relaxed and we chatted away like we always have done,Christine's tongue loosened and she began to talk a little about last night and how exciting it was,i said i thought so too and told her i didn't think i could wait a week.She giggled as she said,
''no,nor me.''
I told Christine she looked great today,she seemed a little embarrassed by my observation,and a cheeky little smile crossed her face. I have noticed how she really likes me telling her how good she looks,I wasn't just saying it to be in her good favour,what i said i really meant.
Her tight top was emphasizing her gorgeous breasts and the fact we were talking about last night and the possibility of a repeat performance was having an effect on me,and unknown to my lovely sister i had the beginnings of a erection,and in an attempt to lighten the moment Christine joked,
''Steady on Marty,you'll be getting randy again.''
''already am sis.''
And i pointed to my lap so she could see the lump forming,
''crickey.''she exclaimed,''you devil.''
I told her to keep her eyes on the road,and she asked if i,''sorted myself out.'' when i went to bed last night.
"what do you think?"
That lovely smile lit up her face once more,"well did you?"
''of course i did,and it was good too.''
''i bet it was.''
''what about you Chrissy?''
Smiling,and almost breaking into a little chuckle she said.
''yea! i did too.''
As we drove down the lane towards home, the journey had finished far too quickly,but before we reached the house Christine directed her eyes to my crotch and asked,
''Can i?''
I knew what she meant and almost as soon as i said yes her hand was on my swollen groin and she was squeezing it,i nearly cum in my pants.
''i cant wait Mart.''
The car pulled up and somehow i got out and managed to keep my erection hidden.
The week seemed to drag by,we made things worse i guess by every now and then talking to each other about Friday,and as the days wore on we even started to sneak the odd feel when in private. There was one moment in the garden shed when we had about three or four minutes alone and Christine was squeezing the lump in my jeans and i was doing likewise to her lovely tits,It wasn't a frenzied fumble or anything, just nice and calm and very exciting. We didn't expose any part of ourselves it was much too risky for that,but it didn't lessen the excitement one bit.
I had both of her tits in my hands squeezing them together and her attention to my groin was almost enough to make me cum,it was then at the height of our passionate fumble that i took things just a little further,maybe too far.
I wasn't sure if i had overstepped the mark.
I waited for a response from Christine as i put my hand between her legs and touched her crotch,It seemed a natural enough thing to do at the time,but In hindsight it was very daring to touch her there. She had jeans on but i could feel the heat through the material,and momentarily she stopped what she was doing to me and looked me in the eye,I thought i had blown it. Christine parted her legs slightly,i assumed she was giving me permission to continue touching this most intimate area of her body. Spreading her legs only strengthened my belief that she indeed wanted more. I was now able to put my fingers between her legs,i could only imagine what it would feel like if she had no jeans or knickers on.
I wasn't sure what was expected of me so i pressed my fingertips onto what must have been the right place because a little sound of approval came from her mouth,and once again she had her hand back on my now fully erect cock squeezing and rubbing it.
Things were really heating up now but not for long because we heard the backdoor of the house open and somehow we tore our hands away from each other and resumed a normal position,Christine looked flushed,but at least we didn't get caught.
All day long when ever we had the chance we would touch each other, nothing as heavy as our shed activity but none the less very exciting.
I awoke Friday morning and spent the day at work watching the clock slowly tick by. Clocking off time came and i raced home,Christine wasn't home yet but just as soon as she walked in the door our eyes met and i could see by her gorgeous smile that she had the same thing on her mind as i did.
Mum had cooked tea and afterwards Chrissy and me washed up,we were alone in the kitchen and i was desperate to touch her,we playfully bumped our bodies into each other,Christine used her ample bottom to shove me away from the sink and i pressed up against her in an attempt to regain my position by the sink.
We laughed and joked as we finished up,then Christine whispered to me,
"are we still alright for tonight?"
"yeah,definitely."
Another smile lit up her face and she bumped her arse into me playfully pushing me out of the way as she left the room. She looked over her shoulder at me and smiled,God! i couldn't wait for tonight to come.
The family were sat watching the television throughout the evening and i can recall mum commenting about the rubbish they show,she said "dont they ever put anything on worth watching?" I shrugged my shoulders in agreement but i still had images of the "Dracula" film that i watched last week fresh in my mind,not to mention similar images of my sister too.
The time was getting on,and one by one the family slowly drifted off to bed. Christine had bathed and returned downstairs in her dressing gown,she was wearing pyjama bottoms underneath,mum asked if i was staying up and i said i was,Christine added that she was going to have a cup of tea and may stay up for a bit. Mum bid us goodnight and reminded us to switch everything off when we come up,she closed the door behind her at the bottom of the stairs.
Soon the house was quiet and Christine found the film for tonight,unfortunately it wasn't a match for the one we watched last week but it wasn't going to matter anyway we only wanted each other.
It was strange at first,not knowing what we should do so we sat and watched the film for a while,then i stretched my arm across the settee and put my hand on hers,we sat like that for a while,almost like girl and boyfriend.
''come here Chrissy.''
''No you come here.''
She said it playfully and we repeated ourselves a few times until i gave in and moved right up next to her.Christine looked up at the ceiling and said,
