My sis was 14 and I was 13 when we began playing with each other. naked, masturbating each other. Didn't get to screw her till I was 15, and only after I bought a condom. We did it in the shower when folks were not home. She said I could try it in her bum, but in the thrusting, it dropped into her puss. Once that barrier was broken we did it a lot.
Stopped when she was 17, started again after both married. We are 48 and 47 now, still sneak in fun when we can although with family near most times, it seems like a lot more quickie blowjobs. Havent used a condom with her since teens. Family is best!!!!!
