Carmen and her husband stood in the doorway naked, temporarily forgetting their condition.
"Did you just fuck?" asked Carmen disbelievingly.
"You fucked your sister?" bill said, a smirk on his face a growing hard on between his legs.
It was difficult to answer them being in the position we were in and seeing them in the condition they were. Carmen stood their, her huge 36DD tits heaving, her erect nipples and silver dollar sized aureoles for us to stare at. The small strip of black pubic hair outlined her still wet pussy, cum dripping out of it from the good fucking I was sure bill had given her.
"We were drunk and horny listening to you two, that we couldn't help it" said T from below me.
I was still cock deep into T's pussy and hadn't tried to disengage or cover up our nakedness just as Carmen and bill had done nothing to hide their. I could feel my cock start to come alive inside of T as she lay there, all four of us staring at each other. The thought of being busted and naked in front of Carmen was beginning to arouse me.
Theresa moved below me and I figured she was trying to get me off of her so I pulled out and allowed her to sit up.
Carmen and Bill were still dumbfounded and by the looks of things actually starting to get a little excited by what they were hearing and seeing. Neither of them moved from their positions by the door and neither tried to hide their nakedness.
"Well if anyone wants to know, Johnny fucked me good," said Theresa trying to lighten the moment, "he is an excellent lover, and I love him with all my heart, so if it's not alright with you, it is with us," she said smugly.
"Carmen, Bill look we're all adults right."
"We heard you two in your room, we got horny we did what we needed to take care of ourselves."
"Yes T" Carmen said but that doesn't make it right screwing your brother."
"Well neither does letting him get hard seeing you naked, but you haven't covered up yet, and look what your doing to him," she said as she grasped my now inflated cock in hand..
"Look" she said "you can let him fuck you like you've wanted to since we were kids, but never did, and say it was the alcohol in the morning, and that will be the end of it, you never have to do it again."
Carmen looked shocked at what Teresa suggested whether real or feigned, she looked to bill.
With a smile on his face he said "Go ahead honey you told me the same thing when we first met that you used to dream about fucking your brother but never did, well now's your chance, go ahead."
"That would be ok with you bill" Carmen asked incredulously, "but that's perverted, it's incest."
Bill said "it wouldn't be like you fucked a stranger, he's family I know you love him, so it's alright, it's actually kind of a turn on" he said looking down toward his now rapidly growing member.
