Yurika and Hikari are on their first hot spring trip together. They are best friends and lovers. They kiss each other without anyone to disturb them. Their tongues entwine erotically and they exchange saliva. They lovingly lick each other's fingertips, armpits, breasts, clitoris, vagina, and toes. They want to feel themselves as one, so they moan and feel each other with a double-headed dildo.
