[Boukoku Daitouryou] Atarashiku Santayaku ni Natta Sensei to Kodomotachi [CulturedCommissions]

A busty teacher bursts into her classroom dressed as a very skimpy Santa, announcing she has presents for her young students—but the curious girls are far more interested in the generous cleavage spilling out of her outfit. What starts as innocent groping and nipple-play quickly escalates into a full toy-filled takeover, with the kindergarteners binding their flustered sensei and taking turns grinding, buzzing, and teasing her until she's a drooling mess. Turns out the real Christmas gift was the teacher being thoroughly dominated along the way.
