[Mozukubotan (kuromusi)] Gyakuyuu Senki (Senki Zesshou Symphogear) [desudesu]

Kirika and Shirabe, the inseparable duo, let a man into their private world and discover that watching your best friend get fingered first is its own kind of torture. What begins with nervous glances and a breathless 'this guy... he's good!' spirals into a sweaty threesome where each girl takes her turn spreading her legs while the other watches, moaning through every deep thrust until 'I'm taking it in' becomes a shared surrender. By the final page both are gasping and clinging to each other through the overwhelming pace, their bond tested in the most intimate way possible.
