I surprise my sister-in-law in the bathroom with a lace panty and fuck her on all fours

While my sister-in-law is changing in the bathroom, I take the opportunity to spy through the keyhole and see that she is wearing a sexy lace thong. I can’t resist the temptation and I sneak in, surprising her. She tries to cover herself, but I abruptly turn her around and put her on all fours. Without warning, I pull down her panties and slam my hard cock into her wet pussy. She moans with surprise and pleasure as I fuck her hard from behind, enjoying her perky ass.
