more mer sex

"Nice scales Bro." Stacy comments after you catch your breath "And good job with your tongue, almost as good as the girls." she adds.

"Girls?" you state in disbelief.

"As I said before, merfolk and half-mers have a higher sex drive than humans. All this time in lockdown I have been without a boyfriend and in an all-girls dorm. I had to make do with what I had." She explained.

"So your Bi." You concluded. You took your first good look at your sister in her mer form. Now that you got a good look at her tail, you saw that it was longer than yours or mums and she seemed to have more control over it. He breasts were D cups, you had checked her bras once. They bobbed nicely in the water with large areola with hard nipples sticking out showing her arousal. Her face was very similar to your mothers.

"Not quite, I was never attracted to my friends nor they attracted to me, except Jessy but I let her down easy. We just all need some release and wanted to experiment. I am glad you are still hard, as I said I need cock." Stacy rebutted and she wrapped her tail around your cock to rub it back to full mast. "Ah, that's better, good as new." She remarked at the state of your bulging erection.

She glided forward in the bathwater, her body slipping over your tail sending shivers down your spine. Her breasts pressed against your chest as you felt her stiff nipples rub against yours and she came in for a kiss.

She broke it quickly just as it was getting good. "Ok, that was weird. Guess you still kiss like my brother."

"That is because I am your brother, and it was just getting good." You reply, slightly offended.

"Look, you may be ok having an incestuous baby with your own mother. And I did slip into your bath, let you see me naked and sucked your cock. And Ok you did eat me out better than any other man. But, I am still not used to this whole **** thing. I am really just here because I need this cock." Your sisted declared as she reached down and gave your cock a squeeze. "So cut me some slack and fuck me hard." She demanded.

You didn't need to be told twice. You shifted form sitting in the bath to laying in it, pulling your sister over you. You felt her hand move your cock into position and you thrust as she moved her hand out of the way. "Oh, your pussy is way tighter than mum's" You let her know as the walls of her vagina squeezed your cock so hard you could feel her pulse.

"I said don't make it weird." She protested but shortly her protests were drowned in a symphony of moans as the two of you felt pleasure in unison.

"Mmmm ah yes!" You moaned as you began thrusting.

"Oh oh oh." She squealed as she matched your thusts.

"Yes yes Yes" You scramed underwater to avoid others hearing it.

"mmmmmmuuuuuuuumm, ah oh" she moaned in response wrapping her tail around yours forming a double helix.

"Oh Oh Oh Mmmmmm Mmmmm yes" You moaned pressing your head between her breasts then latching onto her left nipple

"Oh yes, oh yes oh yes" she screamed as you thrust into her fast and hard while she played with her right nipple. She felt her orgasm building and you could feel it too.

"Stace, I'm goina goina" You moaned on the brink of orgasm, your tails still intertwined your hands replacing your mouth on her breast. Your right-hand intertwining with her right had on her right breast

"Oh yes Yes me tooo, thrust deep oh yes deeper. I need your cock deeper inside me" she begged

You thrust in one last time and felt her vaginal muscles hold you deep inside her as you shot your cum onto her cervix.

"OH YES CUM INSIDE ME, BROTHER, FILL ME UP!" Stacy screamed at the top of her lungs. There was no way the others in the house and maybe the neighbours next door didn't hear that.
