My sister-in-law follows me while her cuckold husband is away

My brother-in-law is a pervert. I came from a trip to visit my boyfriend who lives in the same house as my brother-in-law, but he wasn't there. My brother-in-law was alone, so I went by and my brother-in-law started seducing me until he convinced me to eat his big cock and let him fill my tight pussy with cum.
