We 69’ed each other and her pussy became dripping wet.I inserted my forefinger inside her vagina and vibrated her walls erratically. My sister was d...ipping water out of her vagina. I sucked her clitoris and it tasted like salted meat. I fingered her and she sucked me back.After a few minutes, I was about to cum. So, I stopped my sister from sucking more and I started fucking her in her ass in doggy style. I fucked her till I came inside my sister’s ass.As I was getting flaccid, she sucked it.

I heated the oil mildly and started applying all over starting from legs, moving to thighs, inner thighs. I could now see that some part of her panty near her vagina was shinning a bit due to getting wet. She was wet already now. I applied oil on her back but her bra straps were disturbing. I tried putting my hands beneath then but it was tight and getting difficult. Without even asking for,.
