Is There Anything As Exciting As Those First Few Times?

I remember being so excited I was shaking some as my fingers first traced around my sister breasts and nipples, the first touch of hers around my cock made me just about ejaculate seconds later. My first taste of her pussy and never wanting to stop licking it, taking her underwear and smelling it at night while I jacked off, the memories of it all are just amazing to me. One of our cousins and her were really close and one afternoon when she was over at our house my sister came to my room and said Hey, guess what?! Lisa wants to join in with us and play around, my brain about blew out of my head because she had really large breasts compared to my sisters at the time and we were all about the same age.
Lisa came into my room like five minutes later and my sister said she would just let us have some fun first then come back and like twenty minutes later she reached under me and began playing with my cock as I laid there licking Lisa's pussy, my God those were some incredible days I would give anything to go back to again. They would both lay on the bed naked and just let me run my fingers all over them, they would get on top of one another kissing and playing around with each other while I touched them where ever I could, both sucked my cock together several times and would run their tongues together. I hope those memories never leave my mind for sure.
The time both of them got in doggy positions on her bed, wanted me to go back and forth fucking them then ended up in a sixty nine with me going back and forth getting sucked on and fucking them, seemed like my cock never go soft until we were done. I have never repeated a threesome since those two in my teens, brought it up with my wife a few times and she just laughed telling me no way.
