To be honest though, concidering the fact that the average 15 year old girl is used to giving a blowjob to a boy if asked and the amount of underage sex and such, I dont really think there is anything wrong with a teen sex story. People can no longer act that a teenager will not have had sex, when free comdoms are given out to them to prevent teen pregnancies.

Go ahead and write a story, as the average teen could may have already done what you put in. Thats what I think at least...
