SF Girls ~Assigned as Commander to a Mecha Girl Unit, I'm Drained by Power Sex with the Tight-Suit Onee-chan and High-Leg Girl~

The new commander of the 108th unit has his ejaculations managed through morning sex with his secretary SF girl Shiroe. Swordmaster Kurona defeats enemies on the battlefield, masturbates afterward, then returns and embraces Shiroe while greeting the commander as her new subordinate. Claiming energy shortage, Kurona demands the commander's semen, barges into his cramped bathroom without showering, and fingers and fucks him in power sex until she squirts, then takes him to bed for armored paizuri and power riding that milks multiple loads as energy. White high-leg gunmaster Shiroe interrupts, scolds Kurona for roughness, force-feeds a nutrient tonic that restores his erection, and the three perform double breastjobs followed by successive vaginal penetration and creampies. After hours the commander collapses with headache, nausea and nosebleed while Tama, who sold the tonic, monologues about its severe side effects and addictive nature.
