It was the two in the morning. At this time, everyone in the neighborhood would usually be sleeping... but not Alyssa. She was much too excited. Tonight was the night. Tonight was the night that she was finally going to do it. As she got up from her bed, she heard the snores of Cindy, her roommate, from across the room.

"Finally, my sweet... finally, the day has come. I'm so excited," Alyssa whispered to herself, careful not to wake Cindy up. She turned on the lights, but Cindy was a heavy sleeper, and the lights flickering on overhead did little to disturb her sleep. Neither did the soft handcuffs that Alyssa placed over her wrists, binding them to the posts on the corner of her bed. She was sleeping face-up, with her back on the bed; perfect for what was about to happen.

"Time to wake up," Alyssa whispered, sitting on Cindy's chest. She put her hand on Cindy's chin, shaking her as her eyes slowly rolled open.
"Huh... what? Alyssa? What time is it?" Cindy muttered, still half-asleep. She attempted to move her arms, only to realize that they were cuffed to the bedposts. "What is this? Alyssa, what are you doing?"

"What I've wanted to do ever since you moved in," Alyssa said with a smile on her face as she stripped off her pants and underwear, leaving herself completely bottomless. "Ever since I saw your face, I've wanted to ride it, to smother you with my rear, to put you to sleep with my ass... for good."
"What do you mean? Alyssa, you're scaring me!" Cindy said as she began to squirm. "Get - get off me!"
"I'll only get off you once you're nice and cold," Alyssa said, scooting up towards Cindy's head. Soon, her ass and pussy were hovering over Cindy's face. "Take a deep breath..."
"Stop, please - mmph!" Cindy tried to say before Alyssa's ass engulfed her face. Alyssa reached down, grabbing the back of her head and pulling her face up so that her nose dug into her pussy and her mouth pressed up against her ass. She adjusted, making sure that Cindy's airways were fully sealed as she began to grind against her face, using her nose to pleasure herself.
"Oh, Cindy, you feel so good... I want you to make me cum before you die," Alyssa said, grinding harder against Cindy's face. Cindy's squirming had grown into all-out thrashing and struggling, her arms pulling hard against the cuffs as her legs and hips kicked and thrashed about. However, Alyssa's ass remained firmly against Cindy's face, locking it in place despite all of her struggles. Shouts for help became muffled vibrations that only stimulated Alyssa further.

"Yes, that's it... struggle harder... you're just making me more horny," Alyssa continued, moaning as Cindy's thrashing became weaker, her pulling against her cuffs less frequent as her kicks lessened in power. In response, Alyssa grinded harder against Cindy's face, trying to push herself to her climax before Cindy expired beneath her. She was getting closer and closer, but could tell that it wouldn’t be long before Cindy would suffocate. “Come on, almost there… oh!”
Finally, after a little more grinding and pushing Cindy’s nose against her clit, Alyssa climaxed, cumming all over Cindy’s face. Her fluids spilled out and over onto the bed, staining it, but Alyssa didn’t care. Cindy went still beneath Alyssa’s ass, but she didn’t care about that either, sitting in bliss as waves of pleasure radiated up from her genitals to her brain. Finally, once she came down from her high, she looked down and noticed that Cindy’s body had gone limp and was beginning to cool down. She stood up, checking Cindy’s pulse to make sure that she had passed away.

“So long, Cindy… consider this your eviction notice,” Alyssa said, giggling to herself as she thought about finding a new roommate. One she would eventually do the exact same thing to...
