Slutty SIL

SIL becomes my slut after her hubby cant satisfy

my SIL is a slutty little vixen. she got married 2 yrs back but has become bored with her hubby.i think she is jealous of my wife for being with me. my sex life with wife is vanilla but good.I am not bored with her but thoughts of using another women constantly comes to my mind.
for past 1 year, my SIL has been eyeing me. 4 months back,once when we were alone, she came onto me n we ended up kissing.we immediately stopped but the incident left a mark on my mind. since then i have noticed her touching me gently in passing whenever she could.
a month back,she n her hubby had come over for drinks n stay. 2 hrs drinking later,her hubby n my wife were sleepy.they decided to go to sleep while we talked.she was sitting next to me looking at me with horniness. i wanted to do something but ws worried. she then did something crazy. winked at me n went n locked both bedroom doors from outside. i was so shocked but turned on also.
we started making out n i was getting hornier.i knew the slut was desperate. so picked her up n took her to the kitchen. made her kneeel down there n dropped my shorts. she was so shocked when she saw my thick cock.she was slowly sucking on the head when i grabbed her by the hair n said,'open ur mouth wider slut'.she obediently did it n i started fcking her mouth roughly. i dont think she had deeepthroated before so she kept gagging n choking but refused to stop.
after roughing her mouth for 10 minutes,i was close to cumming. i held her close n shot my load in her mouth. she choked a bit,tears running down her face but swallowed it all. n to top it all up,she thanked me for my cum.
even after cumming i was very horny. i took her to the sofa n made her get me hard again with her mouth. we couldnt talk much or mmake noise,which made evrything even hotter.i pulled dwn her pantied n her cunt was soaking wet. shoved panties in her mouth,bent over the sofa .she wasnt used to big cocks so took sometime to get her used to it.then just started ramming her cunt hard.the slut came twice in 15 minutes n i was close to cumming as well. i pulled out of her,pushed her to knees n came in her mouth again.
she got up,unlocked their doors,cleaned up n sat down with me again. we decided to do this again soon n i cant wait for it
