[Senaka] Nii-chan no Kanojo [ADTL]

A young boy's quiet afternoon turns dangerous when his older brother's girlfriend corners him alone, teasing the flustered little thing about his cute face before leaning in to ask whether he wants to do it. She's all heavy breasts and soft curves, a beauty mark beneath her eye, and she offers him something no one else can — his very first time with a woman, even if that woman belongs to his brother. What starts as playful torment melts into a sweat-soaked, breathless cowgirl ride where she coaxes him through every overwhelming sensation, whispering that it's fine to let go and cum lots.
