Busted in stepsister panties and got asked about then this happens

have sexual thoughts about my stepsister and busted on her panties I have been attracted to my stepsister sister for sum time she slim thick short lightskin and one time her panties we’re mixed with laundry that instantly got me hard so i got them and jerked with it and left giant cum Stain. So the next day she went in my room and asked I know how the cum stain got into her panties “I said I’m not sure but I saw them in the dirty laundry “ she said “ well somebody busted on my panties and there only two guys here.” I said well who do u think did it” she said well u have been looking me up and down and looking at my ass so i know ur attracted in some way i said.” Yea you have a nice ass shape but that doesn’t mean I did it. She said .” Well it’s obviously I get u hard and u look at me so I think it’s u . I finally admit and said . “ yep u caught me but you can tell the parents because I didn’t touch u physically . She said it’s ok and told me that if we go into my room and “solve the problem “ then I won’t have to bust her panties anymore I said fine. So went in my room she pulled her pants down then said get closer then then I pulled my dick out then she started to jerkin me off from behind her and put my tip on her soft ass I was so close to nutting till she turned around and put my dick on her pussy and start rubbing it on the outside while we’re standing up and I was at my climax so I busted on her pussy then turned her around and rubbed it on her ass then she said it this what u wanted to feel I said basically but I didnt think I would actually get chance to do anything with u she said well don’t nut in my panties anymore this is your last experience and said ok so after we cleaned up while she walking out she gripped my still hard dick and said next time want to fuck then she went back her room till step parents came home😹
