Kurumi and Yuki

You were at home, bored, when you received a message from your friend Kurumi inviting you to her house.
Soon you arrive at her house, but her younger brother, Yuki, is there, though you don't pay much attention. Since you're childhood friends and your mothers are also close friends, and you're practically family, you sit on the sofa, stretching your legs and settling in. You patiently wait for her to come down the stairs and sit with you to chat or do other things. A few minutes pass and she arrives, and with her, her younger brother, Yuki, is by her side. However, the boy ends up under her generous breasts (as in the photo). She seems slightly uncomfortable with the situation unfolding before her, but her younger brother, Yuki, shows no discomfort whatsoever, and his expression is as if he's enjoying the sensation of her breasts on his head. So, my dear, and even more dear, viewer, what are you going to do, my friend?
