My disgustingly cute little sister won't leave me alone, following me into the bath, toilet, and even bed, clinging to me tightly! So even though it's my sister, I can't help but get an erection, which is troublesome. To drive her away, I jokingly pretended to attack her and grabbed her breasts... then she looked at me with wet eyes and said, 'It's okay if it's you, big brother.' She said, 'Do whatever you want,' so I couldn't hold back and came inside her multiple times, covering both her body and pussy with cum, making her drenched in it inside and out!
