I am looking for a Yaoi. It's about two brothers and the one day the older brother take a friend to home (seme). The yonger brother (uke) doesn't like him because he thinks that him is interested in his brother (he thinks that his older brother is someone perfect). The seme tell the uke that he isn't going to attack his brother if he lett him have him. The uke starts falling for seme but then he finds out that the seme is going out and doing it with him because of a bet. There is other story about his older brother (seme) that have a brother complex so he acts like he is perfect around his brother but he actiolly is not like his brother thinks. He have a lot of sex-friends. One of the sex-friends (uke) falls for him so tell him that he wouldn't do it with him again if he didn't broke with all the others sex-friends. The seme does what the uke asked.
Sorry for the bad english
