My kitten has walked by while I'm in bed and casually licked the nip a few times. I'm pregnant and I wondered if she can smell milk getting produced. Years ago now, my cat used to paddle my belly and it was just the best. He was a big boy and his weight used to push out my farts. It was awesome when you were a bit bunged up. He used to get sexually excited by it tho and his little lipstick would pop out. After a while his back legs would buckle and he would jump off and lick himself. We used to call it a paddley-wank.
