Mess Of A Situation

I walked in on my little brother’s nerdy girlfriend Amy railed by his friend Tyler on my dad’s couch during a sleepover. I awoke looking for Amy, when I heard whimpering coming from my dads basement. I froze immediately when I could make out the details… “ Ty, oh fuck, your cock… Is so good… don’t stop”. I was wet, but my pussy flooded when I saw Ty naked with his huge cock, spreading Amy into a split. They couldn’t see me, I don’t think they would have noticed. Ty was devouring her, squeezing her huge tits. I stood there and fingered myself. I was so turned on, my head was clouded from listening to Amy’s drenched pussy. Amy started complaining about her insides being sensitive, but he was thrusting so fast it made her shut up. He was yanking her down until she submitted. He came in her pussy, they both collapsed, I had my orgasm. I went back to my room pretended to be asleep. Amy came back a few minutes, I could hear her whispering outside my door. “Ty please, he’s taking me to school early … why are you still hard… just the tip”. She was blowing him outside my door! I think he came down her throat. We both fell asleep right after. I don’t know if I should tell my brother. I don’t want to be the one to break the news.
