OMG so horny! SEDUCED MY STEPBROTHER in a MICRO-BIKINI!

He couldn't resist when I suddenly stood in front of him in my new super tiny bikini! First I asked him quite innocently if he thought I could wear the bikini to my date at the lake tomorrow! Then my stepbrother wanted to take a closer look at the whole thing - but it didn't stop at looking! I noticed that his cock had gotten super hard from the sight and was even sticking out of his shorts! That was just what I needed, because I was already tsuper horny and it was also the perfect opportunity to test the bikini for its fuckability before my date! It definitely passed the test, but unfortunately it got a few cum stains in the end because my stepbrother carelessly shot his load into me! I hope my date won't notice the stains tomorrow and add more!
