So I come home from work after I was sexting her sister the night before. I could've fucked her sister once before but I panicked. Anyway I got home from work to my gf and my sister talking about our wedding drinking wine. They went for a run prior so they're both in tight spandex and tank tops. My gf has d cup great Rita but my sister only has b cups but big nipples. I know this from HS when I use to take really longggg showers and she would come in and say hurry. Lol. So they were all good and I took a shower when I went upstairs in a towel I heard my sister say I was looking skinny. My gf than said there's no way he is because I'm feeding him well. Proves the wine was working when my bf brought my sister up and said seeee look hun show your sister your v. Not going to lie I had no come back when my sister said yeah show me. I did and she came and put her hand on my stomach. My gf then said btw he's been asking me for a threesome and I had to hear it from my friend first. Talk about awkward. My little sister said well I'll kiss you if you dont mind???! To my gf. At that time my gf sister can in with her dog and blatantly walked up and was like derrrr... my gf , my little sister were on the bed kissing and mad obvious so her sister was like wtf. I said at that time"well if we're gonna do this can we put the dog away?" Them two were making out while her sister went and came back w/o the dog. I fucked my sisters brains out first while my gf was watching then her sister then my gf last. Days later I got shit because I had sex with two other girls before her...smh I'm still paying for that night
