Hell Yeah!

"Hell yeah!" you say enthusiastically

Lexi just smiles and walks up to you at the door , she arcs her back spreads her ass for you and winks , You feel like your dick could cut diamonds after seeing that.

You begin to press your dick to her asshole , still moist from fucking her a couple minutes ago. It's much tighter than he pussy and you need to really push to get it in but when you do it is sooo much tighter than her pussy , and it feels amazing already.

You hear Lexi let out a gasp as you push your entire cock into her tight ass and start to slowly pump away.

After a minute you begin to pick up the pace and really start pumping your sisters ass with your hard cock. The feeling can't even compare to any of the other holes of hers that you've used today , it is so much tighter and it send jolts of pleasure through your body with every small movement.

The room fills with the moans of both of you and you are going at full speed just as the door opens and Lexi's face is visible to your friend Steve on the other side of the door.

Her ass is too good and you can't stop fucking it even if you might get discovered so you keep going while Lexi talks to Steve.

"Hey umm Lexi uhh have you like seen Liam anywhere" Steve stutters the words out as he has a huge crush on Lexi

Lexi moans in his face and heavily breathes out " no , I uhh" She moans loudly again "haven't seen him" She breaths out.

"Uuuhhhh OK , what's on your face?" Steve asks , gesturing to your cum.

"Face cream" Lexi moans out.

"OK Lexi , uhh bye I guess" Steve stutters as he walks away.

"Come back in a few minutes Steve" Lexi calls out to him , You are unsure why.

The door closes and Lexi smiles at how naughty she felt , talking to someone with a dick in her ass

"Liam , that was the hottest thing ever" She breathes out as you are still pumping away.

The pleasure keeps building and you know you won't last much longer , your sister's ass is just too good on your cock , it's even better than you dreamed of it being.

Pleasure shoots through your cock , your body and straight through your soul as you cum deep inside your sister ass , in the most powerful orgasm you have ever felt , Lexi writhes on your cock as she orgasms at the exact same time and your moans of pleasure release at the same time.

"Lexi I'm in love with your body" You breathe out , still coming down from the life changing orgasm.

"I fucking love your cock and I'm still really horny" Lexi responds

"Ill be back in a couple minutes , I need a quick break" You say as you walk out the door.
