[Circle Eden (Diisuke)] Eirin ga Oppai o Ijiraremakutte P-Cup ni Naru made no Hanashi (Touhou Project)

Eirin Yagokoro, the unflappable doctor of Eientei, prescribes her nervous male patient an unconventional treatment—hands-on breast massage sessions she insists are 'just part of your treatment,' which soon escalate into full paizuri as he works up the resolve to ask for more. Even Reisen notices the change, teasing the doctor in the bath about how the sessions have made her 'a lot nicer as of late' and left her flustered when asked if she enjoys them. Clinical distance finally collapses on the examination table, where he pins her down, coaxes out a breathless confession of love, and earns a 'congratulations' for the first of many loads to come.
