"Maybe Sister is masturbating?" I thought my sister was on all fours and masturbating with her pen between her crotch and when I heard that she was training her lower body.

When I got home, my sister was wearing a great outfit and putting a pen in her pussy? I was surprised to learn that my sister is a training that has the effect of toning the lower body, but she is just lewd! I couldn't hold it in and inserted it raw! The training effect makes your vagina tight and ejaculate in no time! My sister seemed to be excited, and instead of getting angry, I inserted myself in a reverse cowgirl position! I cum inside her so much that she overflowed from the pussy as she continued creampies without pulling out!
