Celebrating my 18th birthday with my stepdad

My greatest desire has always been to have a night of pleasure on the bed with my stepfather, and now that I really have the conditions to be able to do that without him saying no, I seduced him in the most daring way possible, getting on all fours for him on the bed, in a way that he couldn't even resist and quickly ended up on the bed with me, eating me full of desire and completely, punching my and my too.
