[Low] Tonari no Senpai (Hatsu Iku! KeLolism ~Himitsu no Nakami wa mou Otona♪~) [MrBubbles]

Track-and-field girl Mana figures a scraped knee and a friendly cup of coffee are all her neighbor has to offer—until the doting senpai next door coaxes her out of her clothes while warning her to be careful of kind words, with her boyfriend none the wiser. Breathless and sweating, she learns to take him deep in her mouth before he spreads her bare thighs, and despite the condom waiting on the shelf he buries himself bare in her most precious place, promising to make her forget everything else. By the time he's finishing inside her and snapping commemorative photos of her first time, Mana belongs to him completely—and his busty twintailed companion is already posing at his side to welcome her into the fold.
