My sister is very cute, neat, super shy, and my type! She is so defenseless and unguarded that I can see her cleavage, nipples, and panties as much as I want, and it makes me agonize every day, but when I see her sleeping defenselessly, I can't stand it anymore! I put aphrodisiac on my erect penis and thrust it into my sister's pussy as hard as I can, and of course she noticed! But the aphrodisiac worked so well that she arched her back and came again and again! "It feels so good~" she said, drooling, with a vulgar look on her face as she went crazy, and asked me to cum inside her again and again!
