OOhh I'm sooo going to come!!
It was late one night and at a train station where I change trains, there is a small waiting area that is quite secluded, not that there were many people around that late. Those that are at the station that late are usually half asleep. I was so horny waiting and I slipped a hand down my jeans, pulled aside my thong and started to jerk off my swollen and protruding clit. I kept looking around for movement but none was seen so I closed my eyes and spread my legs for one final attempt to 'jill off' to a leg trembling orgasm before my connecting train arrived.
I was too far out there in spasms of jilling ecstacy to stop when I looked up and noticed a guy in the doorway, pulling his wonderfully erect penis in front of me. He smiled and said I had so turned him on and would I mind if he sat in front to me so that he could finish properly.
I was tempted to pull up and fasten my jeans and bolt but he was smiling and turning me on so I lingered my hand in my slit. I just lazily continued to rub my clit while he jerked the full length of his cock and fondled his exposed balls. I could hear my train called so I sat beside him and grabbed his engorged tool to lend him the use of my warm and sticky hand while guiding his fingers into my labia lips and vagina. He started to go rigid and grunt and gasp and then jets of cum shot out of his cock. I could feel it jerk and shoot with each spurt of jism that shot out of it. As he did he frigged my clit and inserted his fingers and I madly fucked his hand with my hips, while I imagined his hard cock inside me, until I had another smashing orgasm.
