Sitting down at the pool with you, my handsome and much older brother-in-law I started thinking taboo thoughts. Staring, drooling over your cock I couldn’t help but wonder how it would feel if you were deep inside my tight and very underage cunt. I was only 15 and you were my sister’s husband what was I thinking?!? What in the world was wrong with me? Well, it didn’t help matters at all when the lady came over and complimented us as a couple and told us how lovely our children were. I gasped…could she have read my thoughts or maybe my body language gave it away! How could she have possibly thought I was your wife? Well, I guess people do think I am older, I mean my body doesn’t exactly look 15. I have always been very mature for my age. I blushed so hard when you leaned over and brushed my hair from my shoulders to give me an Innocent kiss on the cheek. Nothing in my thoughts were anything close to innocent though and I could feel my bikini bottom becoming damp with desire.
We headed back home and while you tucked in the little ones for a much needed nap I decided I was going to seduce you. I brushed my long, brunette strands and put on some of my sister’s lip stick and perfume. Leaving only my bikini on I relaxed on the sofa and waited for you. When you walked in and saw me waiting for you I couldn’t help myself I pressed my body up against yours and then my tongue searched hungrily in your mouth. At first, you pulled away “This isn’t right Sadie we shouldn’t be doing this.” But, then lust won over reason and you kissed back your hands all over my taboo young body. I felt my bikini bottom drop to the floor and your strong fingers probing for my fresh honey. I felt your other hand take mine and place it on your swollen shaft. You started to guide me slowly rubbing my hand up and down your shaft. I felt hot, thick drops of your sex juice slide down your cock and on my fingers. I wanted it…all of it…suddenly I wanted to drain you. My tight, wet pussy started to ache I turned into a horny, slutty little sister craving to be pounded. “Just fuck me I won’t tell.” You pushed me down on the sofa and spread my legs wide up over your shoulders so you could take my tight,young,baby sex hole. At first, it hurt so bad I wanted to scream but then after the pain came intense pleasure and I knew I would never get enough of you. Never get enough of my brother-in-laws hard cock.
It’s okay big brother no one will ever find out that you are really in love with your wife’s younger sis.
Slutty Underage kisses,
Sadie
