My Bro Blow

My sister married a really hot man. I have stayed at their place on summers and he has treated me wonderfully as had my sister. On one occasion when I was 17 he fell asleep in the recliner wearing sweatpants and as her slept he got a hard on. Very large. I just imagined what it looked like and then was on a quest to find out. I would try walking into his bedroom without knocking and such but with no luck. At 18 while at their place, I donned a string bikini and was sunbathing in front of him in their backyard. I like my sister, have an excellent body, at 5’5” and 125 pounds with a healthy C cup I have no want for eyes on me, they always are. I’m a cocktease and moved provocatively while adjusting the towel and saw that he was indeed aroused. I was so bold as to have him apply tan lotion on my back and then commented on his bulge. He said little but he wasn’t trying to hide it either. I went further asking as to his erections size. He said its big enough to please most. He stood up and I turned around on my knees in front of him and groping his groin I untied his shorts pulling them down to his knees. It was beautiful thick, about 7’ inches long but again it was really thick. My hand started working it and he knowing my sister wasn’t around kicked off his shorts placed his hand to the back of my head and pulled my open mouth onto him. My jaw could barely fit around his mass but it did. He face fucked me, tears running down my cheeks, gasping for air, he really treated me rough. I tried at one point to pull away but no, he wouldn’t have it until I forcefully pushed away with all my might. He pulled my tits out of my top as he beat his meat. I thought he was just going to cum on my tits but then he told me to get on all fours. I did! He simply moved my bottoms aside and entered me. God it felt sooo good. His dominance turned me on as he fucked me hard. He put me down on my back ripping my bottoms off and entered me again ramming my c**t until he and I came hard. He laid on top of me and in me for 5 minutes or so. Pulling out he said my sister best not hear about this. I assured him she would not. He has fucked me now two or three dozen times over several summers. Each better than the time before. His dominance is addictive. I should stop but I can’t. I wait all year long in anticipation of going there again.
