New Craving

so recently i've had this thing for my best bro's wife. it started with her kissing me & her showing me her panties by moving her shorts to the side ... all this from her side. so when it went further was with us being very drunk, both our spouses passed out ... i asked her what undies she had on & she showed me this emerald green with black polka dot matching set by opening her blouse slightly & unzipping her jeans . freak loved the tent i was sporting. anyway next time she wears a tight dress with the skimpiest panties which she just had to show me. so it kinda became a thing ... so the time after that we were mega drunk ... again spouses passed out & decided fuck this teasing i wanna see some pussy ... so i pulled her legs apart while we talk. she is very drunk by now ... doesn't resist me taking out her tit ... the i pull her grey panties to the side ... urgh ... shaven ... i tease her clit slightly & suck on her exposed tit. why am i giving in to this chick tho? & why am i craving sticking my dick up to her baby oven & filling her with the biggest & thickest load i can muster???
