I kept catching my Brother-In-Law in my bedroom and I wasn't sure what he was doing in there. He said he was just using our bathroom because everyone kept walking in on him in the main bathroom. Well, I walked in on him the other day and caught him with a pair of my panties in his hand. He ran in the bathroom real quick but I caught him red-handed. When he came out he didn't say a word to me but he was obviously embarrassed, and my panties were nowhere to be found. Finally, I called a girlfriend over during a little get together we were having one night and gave my brother-in-law the biggest surprise of his life. I had never even hinted to anything with him, but I had my hubby send him in to the bedroom where my girlfriend and I wear waiting. We had the panties on that we knew he liked and did a little show for him. We could tell he was super embarrassed, but we could also see the huge bulge in his pants. We both stripped him down and started rubbing our panties all over him until we couldn't take it anymore and started rubbing his huge cock. We both stroked his huge cock until I couldn't take the teasing anymore and jumped onto his huge cock (no condoms). His cock is way bigger then my hubby's ... so it definitely took some getting used to. But, as soon as I started getting used to it, my friend jumped on his huge cock too. She was taking every inch of his cock until he finally exploded a GIANT cumshot all over us. He said he hadn't cum in over a week and we could tell. I told him next time he wanted to use my panties, this was the way to use them. Part 1 of 3
