Her girlfriend's sister, always braless and unconsciously tempting with half‑exposed breasts, saw right through me saying “Your erection is obvious, you know?” — hiding from my girlfriend she made me come over and over with plank cowgirl and mewing fellatio. 宍戸里帆

About this work

My girlfriend's sister… is always braless. I know I shouldn't be looking, but she keeps ending up in my sight… and I end up getting secretly erect. One night… something happened at her house. After being with my girlfriend, I was resting in the living room when I ran into her sister. As always, I was mesmerized by her extremely careless braless big breasts. “Hey, where have you been looking since a while ago?” Oh no! I looked too much! I tried desperately to cover it up, but her sister saw right through me and said, “Your erection is totally obvious, you know?”… Completely defeated by her temptation, she grabbed a weakness I could never tell my girlfriend about. From that day on, my secret days of being made to come repeatedly by her sister—hidden from my girlfriend—began. Beside my sleeping girlfriend… in the bath… as if enjoying the thrill of discovery that would spell disaster if caught, I wanted to run away from her sister right then… but even though I wanted to escape… the mewing fellatio with tongues entwined froze my mind! The plank cowgirl with her beautiful butt bouncing destroyed my self‑control! And even an internal creampie that my girlfriend wouldn't allow… Damn it! Whatever happens—let it be—!!!
