I saw my stepsister giving my husband a blowjob

I let my half-sister spend time at home precisely because she divorced her husband and didn't have a place to live and today, when I got home early from work I ended up catching her in the act, kneeling on the floor already all naked falling with her mouth on my husband's cock giving a blowjob so well done, that ended up making me jealous... Because I saw my man's face of satisfaction being sucked by my half-sister.
