Her Throat Again!

You can't hold back anymore and thrust hard and fast into Rachel's tight throat.

"FUCK, FUCK, FUCK, FUCK!"
Lodged deep in her throat, you start firing off shot after shot of your hot cum. Her throat muscles squeeze your dick again and again, trying to swallow your load and allow her to breathe again. Finally spent, you pull back out of your sister's mouth as she coughs, chokes and wretches.

"You've got the best throat, sis. Seriously, THE BEST."
You help her up into a sitting position while she's still spitting and sputtering after your relentless throat ****. You untie her hands and she takes the t-shirt from you then uses it to wipe all the spit and cum out of her eyes and off her nose and chin.
"Uh, thanks? I just wish you weren't so rough."
You pat her on the head and smile.
"But that's what makes it so much fun!"
She scowls back at you and lays back on her bed. You can tell she's had enough after two rough throat-fuckings and you probably have as well, for now.

"Well, I'm beat, sis. See you later."
You get up and make your way out of her room.
"Uh, sure, whatever."

You head back the kitchen and grab a snack and a drink. You stumble a bit, realizing just how tired you really are.
"Guess I better lay down too. Throat-fucking bitches takes a lot of you."
You laugh to yourself and head to the loft over the garage. You fall down on your old bed and slowly drift asleep, dreaming of future plans for new adventures.
