Absolutely fantastic work! I'd give this a 5/5 but for two small critiques:
1. We see Tara swallow Scarlet's load and her stomach inflate, but then her stomach is normal at the end when they're both laying on their back.
2. The transition between page 58 and 59 was a bit hard to follow. It would have been nice to see Scarlet's penis from underneath, rising up into her mouth so that page 59 made a little more sense.

Base +6
