MIDA-774 My mother-in-law's J-cup areolas were so pathetically sensitive that I invited my senior over; we spent the night sucking on them and "training" her nipples to the max. Ren Gojo

I discovered that my father's new wife—a young woman with huge breasts—had nipples that were incredibly sensitive erogenous zones! So, I invited a senior friend over for a sleepover dedicated to "training" the nipples of this young new mom. She was a beautiful woman with massive breasts. Since we aren't blood-related, there was no guilt involved—plus, having a young woman in the house whose nipples made her cum instantly was too good to pass up—so I had a blast making those huge J-cup boobs climax over and over again!
