The older sister at the book cafe, who greeted me with her usual gentle smile, showered me with the line, "Fill me up with your baby juice." As always, she calmly brewed coffee, creating such a comfortable atmosphere that I naturally became a regular. One day, entering the cafe, I found her sleeping on the sofa. Careful not to wake her, I quietly took the book she was clutching. Then, with the words, "Let's get all wet and mix together," things took a wild turn. What started as a casual chat with the drowsy older sister gradually shifted in tone, pulling me deeper into her spell. Acting completely unlike her usual service demeanor, she aggressively closed in on me, climbing on top. She took my cock into her mouth, licking and sucking it repeatedly without hesitation, relentlessly stimulating me. Lewd sounds of 'slurping' and 'slapping' echoed through the shop, intensifying my embarrassment. Yet, she remained unchanged, crazily begging, "Give me your baby juice," demanding my cum. Ignoring my hesitation, she impaled her own pussy onto my cock, driving us into hot, hardcore passionate sex.
