A lewd yet gentle stepsister who trains others to kiss! HUNTB-743

I was practicing kissing a pillow when my stepsister caught me! I quickly explained, and she seemed sympathetic, saying, "Shall I practice?" So I carefully kissed her lips, feeling their softness and comfort, and immediately got an erection! I seized the opportunity, kissing not only her lips, but also her ears and neck, even her nipples! At this moment, she let out a sigh, her body reacting strongly! Then, I continued kissing her body, licking her with my tongue, and she let out a series of screams! Finally, I ejaculated!
