If we're talking about her being semi-swollen (Like her swelling up to fill out and feel up her figure), it has to be at least once or twice a week. If we're talking fully inflated, it's a bit more rare and it tends to happen every few (1-3) months. Sometimes she does it more frequently, but those are exceptions, lol.

For Jess, she realized she had a thing for Yancy after how courteous and compassionate he was to her after they hadn't spoken in years. Although she treated him with hostility before, he still gave her respect. Most importantly, she adored his positivity and drive. He was the sunlight she needed after bearing with two years of dark clouds looming in her life.

For Yancy, he realized how much he adored Jess when she showed him how fiery she could be while showing how that fiery temperament translated to loving passion. She might've came off as abrasive and prickly, he could see through her. He's a man of faith, and that faith guided him to loving her to the fullest. He did what was right, and it gave them the ability to be wholly open to each other.
