Solana was very tight—not because she had a narrow cave but because she knew how to tighten it. Coupled with Vaan's big dragon, it felt even tighter.
Although Solana's mind went blank from the pleasure, she gradually regained her reason. Soon, she wrestled with Vaan for dominance. She attempted to disrupt his rhythm by shaking her hips and contracting her cave.
Vaan felt like a snake coiled around his big dragon, strangling it to squeeze out all its juice; it felt incredibly amazing and sensational.
Like lying on a grassy field under the warm sun, it was peaceful and serene, soothing and relaxing; it made him want to like climax right away.
However, Vaan was no amateur; he had great self-control. Thus, he was able to refrain from climaxing early.
As a master in the field, he wouldn't allow himself to climax before his partner did.
More importantly, premature ejaculation would greatly diminish the sense of satisfaction from climaxing.
