The first time i showed my cock and realised i was

Well i used to go to college on the train, quite often id sit with these two girls from my village. once on the way back i was sat with them, and they started talking about the biggest cocks theyd seen and how big their current bf's were. They were 16 yrs old i had just turned 18 and still a virgin. most of the guys whos cocks they were talking about were in my year at school. they both agreed that about 8,5" was the biggest theyd had and all the others were over 6". So they then turned their attention to me! "so tim how bigs urs?"(the nice girl) i blushed and said "thats a bit private!" "nah come on, tell us, we're not gunna tell anyone" (the nice girl) "yeh what hav u got to hide"(the bitchy girl, giggling) i went really red and stayed silent "well it must be atleast 6""(the nice girl) (up until then i thought 6" was as big as they got, NOT AVERAGE!) "hah, i bet its like 5""(the bitchy girl, holding out her thumb and finger) i said "i dnt know, i guess its about 5"" "hahaha"(the bitchy girl) they then proceeded to get out the 15cm rulers from their college bags and size up 5". this made them both very amused. they then proceeded to badger me into showing them. after much resistance i buckled like a wimp to their peer presure and unzipped my jeans. i pulled out my semi erect little dick, and they burst out laughing(its less than 2" soft!). i quickly got hard and they hastely measured me, declaring (very loudly for train carridge full of commuters) that i was 4.5"! It was around this point thats i noticed sitting in the chairs in front was a girl that i really fancied and often chatted too. from that day on wen eva i saw the two girls they would wiggle their little fingers at me. and other girls at the college and in my village wud grin and wissper to each other wen i walked past!
