"If you don't wear rubber..." it will be rejected. But I'll try the rough insert anyway. "Aren't you wearing a condom?" I thought it was a dangerous feeling, but I didn't feel like I was rejecting that much, so I slowly pushed her forward and kissed her while suppressing her resistance and inserted it! It's the best time ever! If you insert it, you can touch your waist without worrying about getting sticky and inside!
