That was the start of fucking her 2 or 3 times a month, one night, she said to me, "I have sucked your cock many times, it is time that you ate my pussy." I wasn't sure what to do but, she told me what to lick and suck on and I guess she was pleased as she came quite a few times that night and that started me on really liking eating pussy. After that we would sixty-nine every time before we fucked and I learned a lot about how to eat a pussy, thanks to Gaye.
As I said before, stuff with my sister Sarah was pretty tame compared to fucking her best friend. We had graduated from watching each other get ourselves off to Sarah jerking my cock and me friggin her pussy and we would do that in the 69 position. She always did a great job jacking me and I was making her cum with my hand. My dream was to fuck her but, I really didn't want to ruin what we were doing by mentioning it to her. One night we were doing the playing with each other in the 69 position and my face was just inches away from her sweet pussy, so I took my tongue and ran it up and down her slit and that was the on switch for us. When I licked her slit she pushed her pussy against my mouth and it was game on. I know that I made her cum at least 3 times as I could taste that sweet cum. As i was eating her out, I felt her lips on my cock and then her mouth was wrapped around it and she was sucking my cock and i was in a heaven, my older sister is sucking my cock!! She could tell when i was ready to come and sucked harder and I shot my load down her throat.
After doing that to each other, we were just lying on her bed and we were talking about how good that felt. She told me that Gaye would go into details about what we did and at first she said it was revolting to her to hear Gaye telling her about fucking your little brother but, after a while it made her hot to hear about it. Gaye would say what a nice cock I had and how good I fucked her and Sarah wanted to say, I know all about his cock as I had jacked it and he fingered my pussy but, she said, "I bit my tongue but, I was hoping we could go further. I looked at her and said, 'how much further?" What I heard next totally shocked me as I had never heard Sarah talk that way.
She looked at me and said, "Tommy, fuck me, fuck me harder than you ever fucked Gaye, I want your cock so deep in my cunt that I can feel your balls rubbing my pussy lips." I rolled over on top of her and slid my cock deep inside of my sister's pussy and just went at it. She was so vocal that night I was totally surprised that mom didn't come flying into the room. We fucked all night and that was the start of the best sex I ever had.
The next 4 to 5 years until Sarah got married, I never lacked for pussy and for the most part she initiated it. She would leave her panties on my pillow as a sign to come and get it, we would be at the dinner table and she would lick her lips, just little hints she wanted to fuck.
If our mother suspected anything she never said anything. Our time together just about ended when she married, we did get together a few times later in life but, not like those years we were both living at home. I always came in her, never used condoms but, I found out later she never could have children but, she liked to fuck. I fucked Gaye off and on for a number of years until I moved away. I will always remember my introduction to hot sex by two of the hottest fucks a man could ever have.
