Naruto offers Bee a safe haven in Konoha while Sasuke is off hunting the Otsutsuki. In order to make Bee not feel like not an outsider, Naurto allows him to mingle with the locals within the village's walls. One day while strolling on the village's streets he sees and immediately recognizes Sakura. The two caught up and Sakura invites him to her and Sasuke's household for dinner.
After a couple drinks together the pair started fooling around, and luckily for Sakura, Sarada was out completing a mission in another village. Sakura brings Bee to their bedroom and there they fucked for hours until she passed out due to exhaustion!
