Ship construction is a delicate business! Sometimes a fully-build ship needs to be adjusted to compensate for new combat roles.
In order to improve Ushio’s balance, she receives a special masturbation training from the tender Nagato and strict Akitsu Maru. After all, an erection lowers a ship girl’s center of gravity.
Enjoy the sight of Ushio receiving her training from the two experienced futanari ship girls, with lots of stroking, rubbing and kissing!
