My brother always told me he would grow up to have BBW sex but I never thought he meant with me. I’m the older sister and my little brother is so much younger than me. When he started telling me about how he was going to grow up to be with a BBW like Mom I could never have guessed who he meant. I’ve been away from home for a while and when Mom called me and told me my little bro was budding out I couldn’t believe it and I just had to come see it myself. Sure enough he had a growth spurt in more ways than one.
His chest was so broad and sturdy, and his legs where so long and thick. A sister shouldn’t think things such as this about her brother but there we were. Late at night, everyone was asleep and he was downstair. I could hear his strokes and felt the faux pounding in my head against my cunt walls. I couldn’t help the reaction to what my body was doing. In a trance I undressed and began to fondle my cunt. I could feel his cock gaining strength and a thought came into my head. What if I never look into his eyes? What if I just back my ass up onto his cock? No one would ever say anything.
