When I was 17, I caught my dad and older brother fucking my younger sister. Dad was fucking her hard from behind while my brother was fucking her throat. She was moaning as hard as they were using her. Without thinking, I cracked open the door and started rubbing my pussy. I must’ve moaned too loud cuz dad came to me quickly, grabbed me by the hair and ripped off my shirt and immediately started eating me out. My brother moved between my sister’s legs and started to aggressively fuck her while making out with me. I couldn’t believe what was happening. They pulled out and pushed me on top of my sister. Dad put his big cock in my tight pussy and started to fuck me. Naturally, I started licking my sister’s pussy and she and I 69’d while our dad and brother continued to fuck us. After a few minutes, they pulled out again and my brother started fucking me. At this point I lost track of all my orgasms. After they came inside us, my brother went “Lucy! Clean up!” Our family lab Lucy hurried in and started licking my brother’s cock, my pussy which ended up making me cum hard again, then my sisters pussy and she and I made out during until she came again, then my dad and my brother started sucking his cock too with Lucy. And yep. That was crazy day.
