The protagonist is a virgin living alone in an apartment complex. Awww... poor guy. Or not? Lucky for him there's a hot lady living nearby, and when he encounters her, booyah! Gotta take a gawk at her booty! Those soft swaying titties too. It's like candy for the eyes.
Sure, she may be married, but damn she looks good in jeans... and that delicious fragrance coming from her is enough to drive a man wild.
Now, the hero must ask himself...
"Hey you... you now know there's a super hot lady nearby...! And y'know, you're now finally living alone at your own place, right...? So, like... you're juust hoping to encounter her? To get the chance to pass by and gawk...? Are you sure that's all you want!? REALLY?? Nothing more?... Yeah, thought so."
Young man! Set forth and conquer. Muster up the courage to make her yours!!
