While your Sister-In-Law is over to visit, she manages to trap you in the guest bedroom while your wife is still inside the house. Using her naughty words and teasing body she convinces you to use her raw pussy quietly, as she's been craving your cock for days. She rides you, whispering naughty things and giving you a closeup view of her taboo pussy. She uses her words to convince you to cum inside her during her fertile cycle, knowing how much this turns you on and with the risk of impregnation high you fill her pussy with a massive load; and as you watch it drip out you realise you'll have to make an excuse as to why you both disappeared...and you wonder if your wife hear you.
