DANDY-972 I fell for you, so… I guess I can be your girlfriend. I thought she was shy, so I let her hold me, but she turned out to be a surprising yandere girl!? When we happened to meet again the next day, she kept me going until I was completely drained

A man on his commute gives in to temptation and starts getting handsy with a quiet-looking woman in front of him. When she reacts timidly, he lets her touch him and ends up climaxing unexpectedly. The next day on the train, the woman spots him, gives a sly smile, and presses close to tease him with a suggestive display. As the confused man hesitates, she whispers, You have to take responsibility, and uses her hands and mouth to bring him to climax. Then she takes him to a private place and keeps him all to herself until she is satisfied.
