The more she tries to forget about it, the more Yumi ajumma thinks about Jaejun's cock, as though she wants more. Acting as if nothing happened, but Jaejun is not buying it, as if he can read her mind. Knowing her true intentions, he gropes her and gets her on the edge before ultimately stopping, letting her beg for it through her own volition.
After successfully seducing her, Jaejun gets to enjoy a steamy car sex with Yumi; both a battalion commander & a milf that had been friends with his mom for over 30 years. She had forgotten what she represents to him as she solely focused on bouncing on his dick too much for a woman who hasn't had her breasts sucked since her daughter stopped breastfeeding.
