During a two-week summer vacation with no parents around, cousin Nanami Matsumoto stays behind with me. Her seductive, wet, see-through outfit sends me into uncontrollable excitement. Her liberated J-cup breasts, free of underwear, radiate an almost fetish-like allure. The sheer fabric, fleeting glimpses of her cleavage, and the view of her crotch deliver stimulation far beyond imagination. Naturally, I get aroused and erect just looking at her. And to top it all off, this relative of mine actually lets me creampie her—surprise after surprise.
