Anal.

Quick as a flash your spin Penelope around,bend her over the desk,pull her panties to one side,wet your middle finger and insert it into her ass.
"AY AY AY!" she cries "You want to fuck my ass Papi?""
She puts a hand between her legs and starts to furiously rub her clit,panting heavy as you slide your finger in and out of her tight asshole.
"That's right Papai" she say's looking over her shoulder at you "I'm all ready for your hard cock".
You spit onto the palm of your free hand and lube up your cock.
"Come on baby" she smiles back at you "Fuck my ass"
You remove your finger and replace it with the tip of your cock,slowly you push your cock into her waiting and willing ass.
"Holy shit!" she say's "It feels so big"
To the hilt you find yourself in her hole before pulling back out and then thrusting in.
"FUCK"she cries"FUCK ME IN THE ASS!!"
Her hand rubs her cunt furiously as you start to pick up pace,your balls slapping against her pussy as you drive deep into her.
"SHIIIIIIIIIIT" she screams "FUCK ME HARDER!!!"
Pushing yourself as hard an fast as you can into Penelope's ass you can feel her squirm beneath you,frigging herself nearer and nearer to climax.
"FUUUUUUUUUCK!! FUCK ME!!! MAKE ME CUUUUUUUUUUUM!!"
You pound deeper and deeper into her gaping hole,feeling her ass start to twitch and spasm against your member.
"I'm CUUUUUUUUUUUUUUUUMMMMMMMMMMMMMMMMMMIIIIIIIIIIIIIINNNNNNNNG"
She screams as you feel yourself on the verge yourself.
