My part-time job's married coworker. A small opportunity led me to invite her to my regular private-room izakaya, where we started drinking. She drank at quite a fast pace and soon got drunk, leaning her body against me. Seizing the moment, I casually touched her chest, immediately realizing she had huge, explosive breasts. After further foreplay, I took her home and enjoyed bareback creampie sex. The whole thing unfolded naturally, and since she didn't seem upset at all, we just kept going and had a great time.
