[Asunaro Neat. (ろんな)] 紅先生のお風呂屋教室 (Fate/Grand Order) [DL版]
#286777 - Sally throws off her shirt and undoes her bra, tossing it aside as well. And slowly licks down her tummy, til she reaches her belt buckle. Judy likes Sally's reactions so she goes deeper, sucks harder, and flicks her tongue faster and faster, she feels Sally's walls tightening on her tongue, so she sucks harder.
