On a hot spring trip, I finally met my cousin's older sister and we bathed together! After taking off our clothes, her overly developed breasts were right in front of me, making my dick hard. The older sister was also excited to see the grown-up dick. After bathing with everyone, we had a chance to be alone! While covered in bubbles, washing each other turned into touching each other… The H mood reached its peak and I slipped it in, unable to stop thrusting.
