[Hyenadog]

Hitsugi's contractions were long with only a few moments of rest between them. This was because the egg would begin to slide back in between pushes, and as it began to crown, it became even harder to make any progress. Hitsugi's opening was tight because it had never been used. His arousal from earlier had relaxed the muscles, but they tensed up with the pain.

"F-fuck..." he panted as he came out of another contraction, one hand slipping between his legs to feel what was coming out. "Oh, god...it....it's huge...." he gasped before he was seized by another contraction.
