Growing up Me and My Sister have always been close and we didn’t have alot of Money so My two older Brothers shared a bedroom and so I had to share a bedroom with My Sister who is the oldest. When we moved and got a bigger house we didn’t have to share a room anymore and sharing a room with My Sister I felt safe and then when I got My own room I felt lonely but didn’t tell anyone. As we got older and she was in High School she became more ” attractive ” and I got a thought about her one day and I was like ” NO, That’s a Bad and Gross ” Thought! I was thinking one day when I was a Freshmen in High School about a incident when I was younger and I was sleeping on the floor next to My sister’s bed and she was bent over in just a long t-shirt and I looked up and saw her panties and No Bra and I remember I couldn’t help myself but to look so I shook My head and I was like ” Why am I thinking about that now?! ” After All these years and what triggered it was I walked by her room and the door was half open and she feel asleep in just her bathing suit and I just stood there and looked for minute and felt myself being turned on! I really thought something was wrong with me! I started having fantasies and dreams about it afterwards and I would just ” masturbate ” to get those thoughts and feelings out of me! This went on for awhile until one day we were the only two home and she asked if I would give her a ” massage ” and so I was like ” OK ” she is My sister and it’s just a massage not a big deal! I started massaging her and when I got massaging her neck and shoulder area she started making a ” moaning ” sound and so I kept going and I felt myself getting hard and so I worked my hands lower and started massaging around her breasts and then worked into feeling and rubbing them she just sat letting me does this and I stopped and I was like ” NO, we can’t do this! ” Your My sister! She grabbed My hands had me do it again and then took her shirt and bra off and I continued. She noticed My dick hard thru My shorts and started rubbing on it and I’m standing there in ” shock and disbelief ” this is even happening! She then pulled my shorts and underwear down and started ” jerking me off and sucking on it ” After this went on for a bit she took me to her bedroom and stripped off and asked me to ” Take Her ” and so I did and after we were done, we laid there in silent and I got up and dressed and went to my room. A little while later she came in said ” We can never do this again and never talk about it ” This lasted for a a couple weeks and one night was sleeping and she came into my room and asked to sleep in my bed with me and I was like ” OK ” and I feel back asleep and awhile later I felt her with her hands down my shorts jerking my cock and I laid there trying to act like I was sleep but when she pulled shorts off and started sucking me I couldn’t act asleep any longer and I asked her ” I thought we were never to do this again?! ” She replied ” I couldn’t help thinking about it and wanted to try it again! ” Even when My Sister had Boyfriends she would still sneak into My room or vice versa and we would have sex! This All ended when she moved out and we never spoke of this again but we are still close.
