"my step daughter's boobs were so fucking big so early it drove my cock crazy. She was only fuckteen years old when I met her, I had her accompany her mommy when I was just dating her. Mom had not updated her bikinis to reflect the massive growth of her stunning knockers. Therefore when she put them on, her areolas pressed up and out the top if the little slender slut so much as breathed. Her tits were riveting, her mommy would whisper to her to let her know that he nipples were showing. After the third time, the little cock tease said outload in front of both of us, "Its your fault my boobs are showing, you never let my buy a new bikini. He's seen tits before, what the big deal? Every night in that condo I would fuck her mommy so hard thinking about those incredible boobs, areolas and nipples that I now knew that she knew that I was looking at them. Her bedroom shared the wall with ours in this rental condo. The walls were thin and she could easily her the grunts and gasps of my animal fucking of her mommy. One night after fucking her mom and firing off a huge load of cum, her mom went to dump the spunk into the toilet and I had to use the other bathroom. I was startled when I opened the door to find the stepdaughter directly outside the door. She clearly had been masturbating herself outside the bedroom door listening to us fucking. I had caught her with her panties down to her knees wearing just a halter top with one boob hanging out. I looked at her in a menacing way. She quickly put her finger to her mouth, sheesh, oh god, please don't tell my mom she begged. I said " tell the truth, were you listening to us and masturbating your pussy? yes. I said I won't tell you mom, but there will be consequences for my silence. There were, non her mom needed to know about. Horny little slut"
