[Hamasei (Tetsukui)] DeliHeal-jou wa Otsubone-sama [korafu]

Aki-chan books a delivery health session and gets the surprise of his life when the woman who shows up is none other than the strict veteran office lady from his own workplace, all mature curves and professional poise as she straddles him and works him stiff with expert hands. Even mid-service she can't switch off senpai mode, cooing at how cute it is watching him try his best before immediately pivoting to scold him for blowing money on daily visits and refusing to let him request her by name. But the power dynamic flips hard when he pins her down and buries his tongue somewhere she never expected, sending the composed office elder howling into a climax she swears she can't hold back.
