The day i got an accidental blow job

Today i was on the bus back from work, when i was sat next to a young blonde girl(later on i find out her name is holly) while on the bus i was browsing through my iphone and came across pictures of my dick, so instantly i try to hide them, but this girl had seen, i then feel her hand touch my le,g and she whispered "You're a big boy aren't you" and in my shock i replied "Yeah i suppose i am" her hand then slowly rose up my leg, all the way to my crotch and she whispered "we're getting off at the next stop" i nodded, i couldn't believe my luck! We got off the bus and she had the nicest bum i've ever seen, it swayed as she got off the bus, i was in shock still, we then found a quiet path way where she rubbed my already hard cock and unzipped my trousers, then she got to her knees and started sucking, the best bit was yet to come, she when slipped her pants off and rubbed her self i was in shock, i'd gone from a quiet journey home to the best day ever.
I now have her phone number and she is coming round tonight, wish me luck ;)
She is 18, i am 19
