Maria watches as Basara has a threesome with Mio and Yuki while they “wash” each other in the bath.
The scene starts with Mio and Yuki showing off their breasts to Basara and pouring shower gel on their breasts. Then, instead of immediately going to him, they begin rubbing their bodies against each other as entertainment for him.
While they’re rubbing against each other, they get very turned on by the situation, so they start getting more intense while also wrapping their legs around one another.
After they finish, Basara becomes involved for the rest of the scene.
Eventually Mio passes out in-between parts, but when she wakes back up, she finds Yuki sucking on her breast, with the scene continuing after Basara joins back in.
