His straight brother didn't want to, but he still fucked him

After a small discussion between siblings, things got out of hand for the older of the two boys. the thing began with a struggle and soon i was undressing him. everything might seem normal if it weren't for the fact that his little brother was totally straight, but he wasn't. he knew perfectly well that he wanted to fuck him and he resisted as much as he could, but when he felt the tail of his brother entering his anus what he felt he could not explain in any way, it was just when he let himself be carried away.this was his first gay experience and his brother did it to let off steam, but what he managed to do was to actually discover that he also liked cocks.
