[GDHH-159] On the night before her wedding, I ejaculated a lot into the throat of my beloved sister! The sister I loved so much is getting married tomorrow!! The last night with my sister who will become someone else's wife, I confessed my feelings to her, and although she refused, she hugged me gently. But that wasn't enough for me, so she said, 'I'll do it with my mouth, so bear with it...' and gave me a throat orgasm...
