One Night With My Neighbor  - Romance novels & stories
Somzzy Obiwulu
Every series has different characters, different situations, and a different story, but the attraction between the characters is always strong. This book is a collection of many hot and steamy romance series. Expect crushes that turn into heated moments, one-night encounters that lead to more, private games that become intimate, fake dates that become real, forbidden attraction, and people who simply cannot keep their hands off each other. Chris moved behind me. He bent me forward a little more. I felt the head of his cock rub against my wet pussy and he pushed in slow. I was tight but ready. He filled me and started thrusting. Each push made me moan around Tyler’s cock. “Yes…harder”, I whimpered. Marcus took over on my boobs, holding them from below and squeezing while Chris fucked me. “More”, I said. My voice was loud. “Please, more.” “You're a slut, aren't you?”, Chris said. If you are 18+ and love steamy romance, irresistible attraction, and stories where one moment can lead to another, then come enjoy the ride. Please read with caution.
