if you're just sucking these guys off and fucking them with protection...no big deal. But if you're having unprotected sex, you are putting you AND her at risk so stop it now!
I'm always safe but I feel bad I'm fucking her dad and bother and she has no idea
Fuck them both at the same time. Get them to fuck around with each other
I agree with the #1 response. But do not with-hold your cock from her Dad and Brother. Give them all the cock they can handle - and together from time to time.
Last night I fucked them both at the same time and my girlfriends mom watched. Best sex ever
Keep up the good work! See if mom wants some cock too. My sister in law gives me blowjobs from time to time but only if I suck her husbands cock in front of her. I wish my wife was into it but since she's a prude, I'll just keep sucking him and having her blow my. She has let me eat her ass a few times!
