He starts sucking
From Create Your Own Story
He kneels beside your bed and quickly removes the bed sheets to expose your average cock and large testes. You grin down at him as he hesitantly grabs your dick. He just turned 18 a few weeks ago and you should be a good big brother and introduce him to the world of sex before he gets pulled into an ally or something. He starts at your tip with a few tentative licks before sliding his tongue up the base of your cock to kiss your cock lips.
