For very info filtered context my(18m) cousin(f20somethin) is gonna be staying at our house along with some other family members for an upcoming event.

Problem: Ive always had a little bit of the hots for her ever since we were young (early/late teens) and im not sure how to go about socializing with her escpecially with all the old people who are gonna be around,

she's plump, pretty, has nice hair, even a pretty nice pair of boobs (even though i dont have a preference for them)

I think it started a few years ago, we were swimming and decided to chicken fight and i (being the absolute unit i was) volunteered to carry her on my shoulders, she sat on the pool deck as i was telling her how to get on my shoulders and as i scooched in to get ready to deploy, I'd found that my head was between her legs, and my face was half a foot away from her pussy which was thinly veiled behind her swimsuit. not wanting to look like a pervert, i looked up at her eyes for the rest of the sentence before going under the water for her to hop on my shoulders.

The first attempt to mount was a failure, so we tried again and succeeded. I remember how she felt against my neck and the sides of my face, the softness of her thighs and the way her ass squished onto my back, but that wasn't what cought my attention. it was the spot on the back of my neck that was warmer than anywhere else on her body, and i could feel it getting warmer as we moved around and fought the others. her crotch accidentally rubbing against my neck as we struggled for victory, of course i didnt let it phase me to focus on the objective. However anytime we'd lost balance she squeezed my head with her thighs which drove me crazy.

But afterwards, the way i look at her has never been the same, i want to feel that warm spot again but on my face and my hips, i wanna know what that warmth tasted like. and i want to make her squirm and twitch while holding her moans in. I even have a few sex toys that I'd much like to use on her.

But alas, one can only dream.
