叔母が限定スイーツを買ってくれるというので一緒に電車で移動。予想外に混み始める電車は、なぜかこの日は女性ばかり！慣れない女性のいい匂いと密着する体に密かに興奮し勃起してしまうボク。こんな所で勃起がバレたら痴●扱いだ…とにかくなんとかしなきゃ！と焦るボク。そんなボクの異変の気づいた叔母はそっとボクの股間に手を伸ばし「叔母さんがなんとかしてあげる」とロングスカートをそっと捲り上げ挿入へ誘導！えっ！ここで？戸惑うボクを押し切りこっそり電車内セックス！おかげで勃起は収まったけど…。中出ししちゃったし…。複雑な気持ちで電車に揺られるボク。するとさっきの挿入で今度は叔母の方が本格的に発情してしまいトイレに移動してまさかの追加ファックに発展！こんなにドキドキしで興奮した1日は初めてです。

My aunt offered to buy me some limited-edition sweets, so we took the train together. The train unexpectedly became crowded, and for some reason, it was full of women that day! I was secretly excited by the unfamiliar scent of women and the close contact of their bodies, and I got an erection. If my erection is discovered here, I'll be treated like a pervert… I have to do something! I panicked. My aunt noticed my distress and quietly reached for my crotch, saying, "Auntie will take care of it," and gently lifted her long skirt, guiding me towards insertion! What?! Here? I was confused, but she pushed me aside and we secretly had sex on the train! Thanks to her, my erection subsided, but… I had ejaculated inside her… I was feeling conflicted as the train swayed. Then, after the insertion earlier, my aunt became seriously aroused, and we moved to the toilet for an unexpected additional fuck! It was the first time I had ever had such a thrilling and exciting day.
