DVRT-053 - My older sister, who has bullied me for a long time, became highly aroused after taking an erectile dysfunction drug! It was too erotic, so I involuntarily penetrated her, and she continued to moan with a vulgar expression, demanding more, making it impossible to stop the deep thrusting!! Tsubaki Rika

My older sister, who has bullied me for a long time, is a gal with large breasts and a bold attitude. Finally reaching my limit, I secretly gave my sister an erectile dysfunction drug. Her skin then flushed pink, her breathing became heavy, and she flinched at the slightest touch, entering a fully aroused state! Eventually, she started rolling her eyes, sticking out her tongue, and drooling, so I forgot my usual frustrations and penetrated her. Then, she moaned with a vulgar expression, saying "Agu igugu," making it impossible to stop the deep thrusting.
