i come home from college to surprise my new family... my mom remarried so i have a new step brother/father. once i get home i realize only my step brother is home so i take this time to get to know him.. i realize he is in my old room so i tell him a dirty story about what i did with a guy on his new bed... i then decide to share some photos with him from college.. but when i reach down to grab my bag i forget that im not wearing panties!! my new step bro sees everything but he also gets a boner.. so i decide to help him out. i pull out my tits and start rubbing his boner, i convince him to let me give him a blow job to help him go down before our parents get home... i blow him and finger my pussy before begging him to fuck me! he finally gives in and lets me ride him in different positions before he gets on top and fucks me missionary until he cums all over me!! hehe welcome home step bro!
