Risky Text to Sister Turns into Taboo Sex

I knew it was wrong, but I couldn't help myself. One risky text to my sister was all it took to set our forbidden desires in motion. I confessed how long I'd wanted her, and to my surprise, she replied with a heat emoji and said she was on her way over. The tension was already thick when she walked through my door, and we both knew exactly where this was headed. She didn't waste any time. As soon as the door closed, she dropped to her knees and pulled my cock out, taking me deep in her throat until I was rock hard. Then I pushed her onto the bed, spread her legs, and buried my face in her pussy before sliding inside her. We fucked like animals, her moans getting louder as I pounded her wet cunt. I couldn't hold back and pulled out, spraying my cum all over her tits and stomach. She looked up at me with a smile, and I knew this wouldn't be the last time we'd take that risk.
