I’ve wanted to post here for a while, so my niece stays with us weekends and we always go out to the lake and have fun as a family and whenever me and her cross paths she’d always gives me elongated eye contact and I normally think nothing of it. This time when we get back to the house she sits on my lap, which she always does as we all wait to clean up and change in the bathroom and as we sit there she’s straddling me with her tank on (no bra) and tight pink shorts on and I can’t help but smell a whiff of her musk and I instantly get rock hard. I moved a bit so she doesn’t feel me poking her but she gets up soon after.
Once I head in the bathroom after her, I see her creamy soaked panties sitting under the sink. I go weak and immediately wrapped her panties around my face with the creamy, damp part pressed tightly on my nose and mouth. I start stoking fast, sniffing and licking her panties uncomfortably, I was so intoxicated by the smell of her juices I came hard in seconds it felt like. After I finished, I wiped some of cum up with her panties, I collected myself and as soon as I open the bathroom door, there she is! Shocked I grabbed her panties quickly and let her know you left these behind, and all she says is “I know” with her smirk and walks away with such a seductive look. I haven’t seen her since last week and I can’t stop thinking about her, what should do?
