When Naoki visits his mother's sister's house, he is flustered by the cleavage of his aunt Kaede... Kaede's mature charm and cleavage make Naoki's crotch erect, and as their eyes meet, Kaede's lips stick to Naoki's like magnets... The two are overcome by an irresistible urge and end up just joining their bodies... It was probably a nice farewell gift from Aunt Kaede to Naoki, who can't return to Japan for a while.
