Watching my 18 y.o. stepsister all naked in bed have fun with her perfect youthful pussy was a pounding blast, but when she asked me to fuck her and finish her off I almost panicked. She is my pounding stepsister, you know, but that extraordinaire tight fuckhole with a lil red bush above it was just too tempting and gave me too big of a hardon to ignore it. You bet I fucked her good and she made me spunk in her mouth like I was her boyfriend or something, what da heck!
