My Sister, Our Secret: Chapter 1 - Truth Or Dare

It was a very slow burn over years with my sister. Yes, you read that right... my sister. It wasn't at all like a porn movie where she walked in on me jerking off and gasped at my cock, and then... We had a very normal upbringing and the usual sibling fights and frictions.But when we were both going to university, and still living at home (we're two years apart), things started to change. We started to actually talk and hang out downstairs watching TV after our parents had gone to bed. I started to drive her places, to pick her up from her classes. We would grab lunch together. We still had our frictions, but it started to feel like we had a real friendship and closeness that we never actually spoke about. We both had separate groups of friends and dated within separate groups of people.I don't know how it happened exactly, but one night when we were downstairs and our parents were in bed, we started Truth or Dare. It started innocently enough, lots of eye-rolling and giggling. Neither of us was picking Dare, only Truth. Innocent questions...until she asked (voice suddenly very low and quiet) "Ok...do you masturbate?" I was surprised that she would be bold and ask that, but I said of course I did, and that she should try it too (smiling, joking). To this, she reacted with "Noooo! I don't do that!" But she couldn't hide her smile.Then she asked, "Is that why you take so long sometimes in the bathroom or in your room?" Very perceptive, she was. I said yes and that sometimes I ...

... need to get it out of the way to get on with my day. She said that's going to make things hard when I go away for work for the summer (I had a summer job that took me away from June until the end of August each year).I said that yep, it would be. But a man's gotta do what a man's gotta do. Then I decided to be the one to be bold, and I said, "Well, maybe you should send me some pictures to help me with that." I said it sarcastically, to have some plausible deniability, to make it sound like a joke.And of course, she recoiled in indignance but STILL had a smile. "I'm your SISTER! Why would you want that?? I'm your SISTER!" Still acting indignant but involuntary smile..."Well, you're a girl. You still have all the right parts. You have that skirt and swimsuit and all that. Be creative and help a guy out." Still, sarcasm and joking tone, smiling. Not being serious. Plausible deniability."Gross!! You're going to have a really hard time then!" And still, indignant and joking but the smile couldn't be hidden.We went back to talking about other things, Truth or Dare dropped. I didn't think that much more about it other than it was an interesting little exchange, especially that she had asked me if I masturbated. But I figured that was that.So away I went for the summer job. This was back in the 90s, before the days of text and selfies. For people under forty, this means that you actually had to write letters to people and send photographs. If you wanted to call home, you had to go to ...
