Lexi's pussy

You stand up and rub your cock happily. You eye your step-sister's pussy as it appears to be 'winking' at you. It wants you to give it some company.

"You'd feel disappointed if I didn't give you first dibs, Sis. Are you ready for me?"

"I've been ready for months," she replies, "Now fuck me."

You smirk wide and bring your cock to her pussy. You guide it in, feeling little resistance at first. As you get halfway in, you feel some tightness.

"He's a big one," Melanie says, "Take him in your cunt like you took him down your throat. Just relax and let him in."

"I'll try," Lexi says, grunting a bit.

You keep pushing, finding your entry getting easier. Lexi's grunts have turned into light moans, accentuated by Melanie kissing her all over her neck.

"Damn- you fill me up, bro!"

"You're nice and tight, sis," you reply, smacking her ass sardonically.

"Ooh, kinky," Melanie says, "Do it again."

"If you insist..."

You reach down a bit further and smack Melanie on the right cheek. She flinches.

"Not me," she replies with a laugh, "Her. Dirty boy."

"Tomato tomato. Now let me concentrate on fucking my sister."

Lexi and Melanie begin to start kissing again, while you finish your entry. You grab Lexi's hips and pull your cock part of the way out. You quickly drive it back into her.

You keep this up for several minutes, feeling no resistance. Cute moans and sighs escape from your sister's lips, so she seems to like it.

"Shit- I'm going to cum," Lexi says, "Make me cum with your big cock!"

You pound her hard and fast, driving that orgasm out of her body. Melanie grabs her by the shoulders and kisses her, keeping her loud exclamation of joy muted.

"Fuck," Lexi says, "That was great. You have to have a turn."

"I intend to. I may even try something special, if he earns it," Melanie says.
