ex g[F] sister, real [FM]

My girlfriends(19) elder half sister is a bombshell of a milf at 28 to two, kind of a pinup look- white, thick, tatted, attitude and ass always-always out. I stayed with them two hours from home for two months of training at a state capital.

Her and her man, 41 drank often and she made insane meals while I was there, made sure to help clean after and supply rent groceries to pull weight. One night he was in garage smoking after our drinks and bbq dinner, kids off to tv in bed.

I began to clean and rinse dishes when she came in her pink low cut top and nice c-cups pressing together when she bent down unloading dishes from the dishwasher.
since dinner and everyone parting from kitchen, she went from tight jeans on her 5’9 thick white frame to really short yet loose booty shorts and same top.
My conversation wavered lol but I kept talking about school or my gf or how good the food was even though Id really felt the ciders they had just introduced to me at that point, as I was still drinking this Friday night to play some videogames after and spin off to sleep.

I began to help her unload, so I could load the dishwasher as I was ready, I went to put some pots down low and she gestured them to her and she bent down at the waist right in front of me in a tight kitchen and slowly put them in still casually chatting me up, her ass was up in the same corner of the kitchen for another minute while she hand swept up dirt in the corner and she lightly complained about how messy it always was. My attention tunnel visioned, her loose grey sweat shorts slid to the side enough and her pussy and asshole partly returned my glance. I was actually lost in her holes and trying to maintain convo, halted task and tracks- when I drunkenly realized I was sporting a huge boner in my shorts, like I could see precum and the shape of the head at a glance down, I quickly tucked upward it in and said I had to use the washroom upstairs where I rubbed a bit but tried to calm down the boner, she maintained eye contact but I think she had to of noticed because I was pretty buzzed and slow at that moment thinking with my dick.
About to leave the bathroom, i looked out the small backyard facing window to see her in the garage on a couch where we smoke with her legs above her head getting pounded vigorously by her black bf of a few months, I watched and regrettably stopped in fear of getting caught cause she easily could see into the window I was in in the position she was fucked in lol.
I wrapped up dishes horny as fuck knowing they were just thru the backdoor and garage door fucking, they didn’t even close the doors. That night grabbing late night snack when lights were out, their door was open barely and I hear sloppy head and his groans and the tv barely going, I bust clean up and pass out.
Doing laundry anytime after an that next day, i began to find that she’d ditch her dirty panties and thongs all over the ground in the laundry room where only her and I entered as her man didn’t do that type of stuff. Once or twice id slowly stroke to her scent, I shouldve kept a pair, I hope she smelt my cock on them. I never made a move when everyday id come from tech school to find her in those shorts napping on the couch.

I found atleast a half dozen sexy thongs in my laundry always on the dry cycle, innocent probably but part of me hopes she wanted her scent on me or because I got her wet she felt i had to dry them.

After some tame normal DMs, she has agreed to rent to me again this fall even though her sis and I split, I hope she gets shared with me if shes still with him.
