Isabella and I were on a bus and the thing was completely full, taking us from our hotel to some big fountain she wanted to see on our little vacation from home. There was standing room only, but we got on first so, I got a seat and eventually, to make better room, Isabella sat on my lap. I was getting kind of horny, so my hand started drawing circles on her outer thigh. I could feel her stiffen beneath my touch and I could feel her ass muscles contracting against my legs. I was way too horny to stop there, but the bus was packed. She leaned back and whispered that she was horny. I immediately was turned on by her admission and began kissing her neck, slowly and as discreet as I could.
Meanwhile, Isabella's hand reached back into my lap, gently stroking my painfully hard cock through my jeans. I had to stop from whimpering and my searching fingers on her bare leg become bolder, working their way up, bit by bit, under her short skirt, but only under the edge.
She turned to me, whispering, "I'm only wearing a thong." My heart skipped a beat. Then she whispered again "And I want to fuck you in front of all these people."
Her fingers started to play with my zipper as I could feel my cock getting even harder, the anticipation and fear of getting caught killing me. I looked around and couldn't see anyone watching, so I slowly eased my fingers along the inside of her thigh, where I could feel the damp warmth coming from between her legs. I pulled the thin strap of the thong to the side and started to tease her swollen pussy, gently parting them and stroking them.
I dipped my finger past her outer lips and gather some of her wetness, being careful to keep my finger wet as I slowly withdrew and brought my finger to my mouth to taste her in the middle of the crowded bus. As I brought my finger to my mouth, I noticed just how wet it was, her beautiful viscous fluid covering my finger. I tasted her. My mouth watered, as I savored in her wonderful flavor. It immediately brought a small moan forward from my throat. I looked around. Nervous. No one seemed to notice though.
