Finally, I was able to have sex with my sister, but I decided on my own rule that "Even if you insert it up to 3 cm from the tip, it won't be sex." However, it is very pleasant to put Ji-Po in and out of Ma-ko even with just the tip, and my sister who gradually wants to insert it to the back is in estrus! After all, insert it all the way! ? On top of that, even a vaginal cum shot...!
