All Names Changed.
I'll call myself Jack now 30 and my sister Jill also 30, years ago we were like chalk and cheese. I studied and she partied, that was until our father cracked down on her. Her school grades were very bad and I was doing great, he told her her grades improve or you stay home. She wasn't happy at being kept home and as was usual for her she wanted an easy fix. Kept home by father's instructions wasn't something she wanted, but she had a bit of luck. My parents went out Saturday afternoons like clockwork. Jill bored at being home came to my room and caught me masturbating myself. She thought she had won the jackpot, but I'm smart and pointed out to her she could tell everybody and I would be teased for a time. But she would still be kept at home, but I added maybe we can come to an agreement. Like what was her response, I'll help you with your grades you help masturbate I said. How was her shocked response, you can masturbate me and show me your breasts and I'll give you the answers to the tests. But we can't have you getting A's straight away as the teacher and and father would suspect something pretty quickly. I looked at her and she said I'm listening, I will teach you a signal system and that will give you the answers to the questions in the test, so there will no talking. At first I will give you enough answers to pass and then you'll get better and better as not to raise their suspicion I said. She agreed pretty quickly and for the rest of that weekend I taught her the finger code. It was simple most test except mathematics were multiple choice, as she sat on my left the fingers or thumb would be left straight with the hand flat on the desktop. First finger equaled A to thumb E. If there were more choices the right hand would have a straighten finger. But most questions had 4 and sometimes 5 choices, for mathematics well I would show the number answer by showing say 4 fingers than closing my hand and than showing say 2 finger till I had shown the full answer. We didn't have wait long as there was a mathematics test two weeks later and my code systems worked fairly well, she got a C+. Better her previous D- and over the following years she improved, not just by my help but also by her actually learning something as well. She kept her promise, she would take her top and bra off and pull me off and we also started showering together. Nothing more then she stroking my cock, our parents were mature parents. Having us when our mother was 39 and father 46, mother died of a stroke at 62 and father passed away in his sleep at 70, he had bad lungs from smoking too much when younger. We both got into university and Jill had it by herself, we also done the same courses and both graduated together. On our graduating night we went further than we had before. We fucked for the first time, I was shocked to find Jill the party king of her younger days was also a virgin. She hadn't said and I hadn't asked before, I thought she must have tried it before, but she hadn't. Anyway once the taboo was broken we couldn't stop. We loved being together, got jobs at the same company and acted like we were married and Jill wore mother's rings. We've 2 children both healthy and Jill is pregnant again with twins 3 months to go, both healthy.
