You're the step-sister of the bride. She just married me and while your husband is down at the reception hanging at the bar you corner me, your new brother-in-law in the bridal suite while I'm getting things ready for tonight. You start out with innocent enough conversation, talking about how boring married life can get, occasionally slagging off your husband and complimenting your new brother-in-law for being such a gent up here prepping everything for the big celebrations later. You are being quite flirtly with some subtle teasing to accentuate your legs and breasts (crossing/uncrossing your legs, letting me see up your dress) but you get more and more bold as time goes on. A slow burn build up with some sweet talk saying how stressful weddings can be and that you need to relax after all that pressure in order to get closer to me and seduce your Brother-In-Law with leads to you getting his cock between your tits, sucking his dick and fucking in various positions (POV virtual sex missionary, riding) and really going hard at it. The fact that we're cheating on our spouses making it all the hotter. During mid-ride you tell your brother-in-law that normally you'd let him finish on your pretty face but given we have to go back out there in front of everyone we can't have you messing up my makeup instead she continues to grind you to make sure she takes all of your cum inside her with none left for her sweet step-sis. At the end we have to get back down to the reception so our partners don't come looking for us but we'll have to find a way to do it again soon.
