So, I'm trying to expand my collection of hentai films with examples of large insertion or inflation (preferably cum inflation). So far I have:

Taimainin Asagi (large penetration, bit of inflation)
G-Spot Express (inflation, enema scene)
Prince Catue ( cum Inflation, large penetration)
Bible Black (enema inflation)
Wild Cat vs Gorilla man (3d animation, ends with an inflation scene)
Wriggle (large penetration and cum inflation
Shion (inflation)

Anyone care to recommend anymore with cum inflation or visible distensions due to enormous penetration? Monster pregnancy/birth is ok in my book too.

I'll dump some stuff in the mean time.
