We Still Laugh About It...

When I was 14 my older sister was cool. When the parents were away she would let me bring my boyfriend over for sex. We had one specific sex act we did often. My boyfriend had a really big dick and I learned to deepthroat. He loved it! I would lay on my back and hang my head over the side of the bed. He would pin my arms down and fuck my throat. One time he got carried away and held it in my throat too long. I couldn't breath. I blacked out and went limp. He freaked out, ran out in the hallway buck naked and yelled for my sister. She ran in as I was coming around. I was laying there , face covered in slobber, boyfriend standing there with an 8 inch boner and my sister trying to figure out what happened. Its or private joke and we still laugh about it.
