gang bang on the back seat of a bus

i sat on the bus after a hard days work..my short skirt just covering my pussy,as i looked up at the last 2 passengers i noticed they were both hunky looking guys who i would let right into my pussy,i noticed the elderly bus driver watching me in the vision mirror i smiled and slowly opened my legs a little and pulled my panties across,he smiled so i moved up closer to him and wispered we should have some fun with these guys and they could all fuck me.The bus driver turned onto a dirt road and the other guys asked what was happening ,i stood up and let my nickers drop to the floor and slowly walked to the back of the bus and spread myself across the back seat and gave them clear veiw of me finger fucking my juicy wet pussy,the old bus driver stopped the bus and walked right up to me put my legs up over the back of the seat and got down on his knees and licked my clit,the other 2 soon came to the party as i sucked them off one by one as they made me come over and over with there lips,i then bent over the seat and asked the old guy to fuck my ass as the others fuck my pussy from behind,the all joined me in cumming again and again......we soon got the bus back on route and travelled the rest of the way in silence.I always travel by bus only hoping it happens again.
