DBDR-002: Ayaka Muto hupenyeza inn ya moto ya chemchemi ambapo wafanyikazi wa uhandisi wa kiraia wanakaa kwa muda mrefu katika milima ya Mkoa wa Yamanashi! Je, ni nzuri kukidhi wafanyakazi wa uhandisi wa kiraia ambao wana nguvu sana kwamba ujenzi wao haupungui kwa kuwatupa na mbinu zao za kiburi?

Ayaka Muto infiltrates a hot spring inn where civil engineering workers are staying for a long time in the mountains of Yamanashi Prefecture! Is it great to satisfy civil engineering workers who are so energetic that their erections do not subside by tossing them with their proud techniques?
