Cuckold Step-Son Watches Step-Mommy Fuck Big Step-Bro

You're my step-mom and I'm your step-son and I've come into your room while you're getting into bed, upset about how every girl I've dated leaves when they find out how small my dick is. You let me come into bed with you and try to console me and cheer me up, saying all the usual stuff ("size doesn't matter", "plenty of fish in the sea" etc.) Suddenly, my younger step-brother bursts into the room needing your help. Unbeknownst to me, you and him have had an arrangement for a few years now, since his cock is absolutely huge, he needs to use step-mommy's hot body to help him drain his massive dick whenever he doesn't have a girlfriend to do it for him. You apologise to me and agree to help him, and he immediately starts ramming his huge cock into your mouth. You suck his massive dick and get your tits out and start titty fucking him as well, while also trying to comfort me about my problem whenever your mouth is free. You eventually realise that I've started masturbating, and you're pleased and even proud of me, saying that being a cuckold might be exactly what I need to do to cheer myself up. You then decide to let my step-brother fuck you doggy style on the bed. You're still trying to comfort and encourage me, but it's hard for you to talk over the sheer orgasmic pleasure my step-brother's enormous fat cock is giving you. Finally, we all cum at the same time, my step-brother giving you a nice deep creampie, you moaning as he gives you a mind blowing orgasm, and me dribbling onto my hand (all the actual cum is just implied). Once you're able to compose yourself, you ask me if I feel better. I say yes, and you politely tell me to go wash my cum dribble off my hands and go back to bed. You then turn to my step-brother and ask if he feels better, and you're shocked and say something like "What do you mean, 'Ready for Round 2' you'll have me worn out step-son!
