She wants to know if she's a good fuck.

Brittney keeps talking, "I hope that's true. I really want to please him. I also wonder?"

"What do you wonder?" You ask her.

"Well I wonder if I would be good in bed, you know be good if we go all the way."

You can feel your hard cock twitching as your sister gives you the opening to fuck her. You have thought about fucking her forever. The chance to do it is more than you can believe. You decide to go for it. You point at your hard cock and say, "Well there is only one way to find out sis."

She smiles and grips your hard boner with her hand. She runs the fat head through her fist a couple of times. You moan in pleasure. She then lies back on your bed and says, "Fuck me bro."

You move between her legs and let her rub your cock up and down her wet, swollen labia. Your sister's cunt is soaking wet. She moans as she rubs your stiff cock over the nub of her clit. You push your hips forward and she gets the idea. She moves your cock down to her slick fuck hole. You insert the fat head of your penis into her very tight opening, she gasps. You slide your hard cock into her lubricated tunnel until you feel resistance. You didn't expect her to be a virgin after what she told you earlier.

You thrust into her, burying your prick deep inside her, and popping her cherry. Your sister gasps as her body stiffens. Once she gets used to the fit, she arches her back, and humps her hips back to meet your thrusts. She moans in pleasure as you fuck her. Her hands go to her stiff nipples. She pulls and twists them as you slam your cock into her.

You put her legs up and over your shoulders, so your cock can penetrate her even deeper. Brittney moans in ecstasy, "Yeah, that's it. Fill my cunt up with your cock. Fuck me hard with your big cock. Make me cum with your cock."

You pound into her for a while longer. You then tell her to roll over on her stomach so you can fuck her from behind. Brittney is more than happy to oblige, as she lays flat on the bed with a pillow under her hips so you can mount her. You thrust into her from behind, your pelvis slapping her firm ass. Your hands roam forward to feel her small firm tits. You rub her hard nipples with your palms as you fuck her hard.

Brittney is writhing in pleasure after a few minutes of your hard fucking. You are glad that she blew you or you would have popped your load into your sister's tight cunt by now. You pull your cock out of her tight hole and lay on your back. You tell her, ?Get on top of me and ride my cock until you cum Brittney, I think you will like it.?

Brittney needs no more urging as she positions her hot cunt over your cock. She takes it to the hilt. She bounces herself up and down on your hard member. You make sure you hit her just right to bring her to a powerful orgasm. She yells loudly, humping your cock even faster as she climaxes. You feel her already wet snatch flood your tool with more cunt juice. Your balls are soaked with her copious lubrication. You resume thrusting into her until her orgasm finishes. Not more than a minute later, you thrust deeply into her, ejaculating a huge load of cum in your sister's tight pussy.

"Brittney, you are definitely a good fuck," you say as you roll her off you and onto the bed.
