I licked and fucked my stepsis

I caught my stepsister masturbating in front of my room and she said she was fantasizing about getting her pussy licked cuz her never boyfriend never does it. Well, you know I can't say NO to a hot chick asking me to eat her out even if it's my stepsis, so I gave her long-awaited oral pleasure right there. Next time she returned the favor and loved sucking my huge cock so much she decided to go all the way. We've been fucking ever since.
