For a year or two I've been thinking I might be bisexual or gay. Guys don't turn me on as such, but I get an erection looking at gay porn, and once me and a male friend made out in the showers after PE when no one else was around.
My 19-year-old brother has seen that I have some gay pictures on the computer, and one evening not very long ago he came into my room and caught me masturbating. He told me he found it hot and had an erection, and I told him not to be worried as I obviously did too.
I wasn't really up to speed with the whole 'wanking' thing, and I told him. he told me to strip nude, and did the same. He got me lying on my back, and straddled my belly. He held his hard erection and masturbated, eventually cumming all over my belly and chest. He told me to swap positions and try it; I'd cum before, but not like this time! One release hit his chin!
We laughed and had a joint bath, where we took turns masturbating each other.
No one else knows, but it's made my sex life! Hehe. Thanks!
