Eira was left to experience a whole mess of sensations due to this lad's reactions to her own actions. She didn't disagree with any of them and in fact found herself panting as she tried to move forward having to catch her breath and deal with the ever so slight tingling sensation in her legs after she finally managed to clear Takumi's face. As she moved forward she inhaled more of this mist, and her thoughts began to deviate from her original intention. 'I wonder if I should stop again...' she thought but the darkness now came from both sides of them, and as she moved forward she'd been hoping to find another vent to push out, but at present there was no end in sight. 'This space is so small, he'd have to touch me if we needed to switch places...' she thought. Unbeknownst to her, every movement of her body forward came with a small moan or grunt she couldn't control and that she could barely feel. "Uh, I didn't expect it to be so long..." she mumbled about the vent. Her body felt hot and more than that she'd come to realize all of her thoughts were sexual. In doing this, there was something going on which she hadn't initially considered due to her own known immunity. 'Was I drugged? Is this what that feels like? It's pretty great~' she wondered as her breaths continued to be labored and her body began to burn. Her face was flush even as she aimed to keep pushing forward, there was only one way out and she intended to find it at the end of this tunnel.
