My girlfriend doesn't want to have sex with me, so I was feeling blue today. To cheer myself up, I decided to hang out with my step sister. She was in her room reading a book but I didn't care. I lied down on her bed and moped until she finally turned around and gave me attention. She came closer, sat on the foot of the bed, and started rubbing my cock. She pulled my pants down and took my cock out to stroke it. She then took off her shirt and began sucking my dick. That really cheered me up, I have to say. She even gave me an amazing footjob from different angles. I really enjoyed staring at her big ass as she pleasured my penis. She removed her underwear and glasses, then invited me to go inside of her. I stepped up and buried my dick in her warm, shaved pussy. I felt a little weird, though, because she is my step sister... but it felt real good at the same time. Oh, I'm so conflicted. Fuck it. YOLO! That's my philosophy now. If my girlfriend doesn't want to fuck me but my sister will, then I'm cool with that. My sister looks better, too. She is thick and curvy in all of the right places. As a chubby chaser who's obsessed with BBW porn, you better believe I'm counting my blessings! So all of a sudden I'm no longer bummed out. Instead, I'm thrusting my large penis into my sibling's box in her bedroom. Life is funny that way, right? And I'm having such a good time. I lay her on her back and smash away. In the back of my mind, I'm thinking about how my girlfriend is missing out on this good dick. Oh, well. All of a sudden, I get really close to cumming and sis gets on her knees to finish me off. Have you ever seen those "When you nut but she keep sucking" memes? That was me just now. And she even looked me in the eyes and said, "I love you." Are you fucking kidding me? I don't know how I didn't just bust another nut right then and there. I responded with, "I love you, too, sis," and I really meant it. If our parents get divorced, I am definitely staying in touch with her.
