After the shagging in Like Mother Like Son (the 4th episode of Class the second series) the 11th Doctor dropped Amy and Rory off to what was present day to them.

One day Amy went out for a walk and stepped through a rift by accident and she ended up a few years ahead in an alleyway. After she left she saw 16 year old Artie Maitland who was smoking weed and he immediately recognised her.

"Wanna head back to mine and have sex?" He said

"Can't say no to a kid as well hung as you!" Amy responded.

"Ya know since that orgy I been getting laid loads, everybody wants a piece of the Artie" he boasted on the way back to his house.

They got up to Artie's room, stripped off and got to fucking. Artie couldn't get enough of Amy's tight wet cunt.

"Oooooooh Arrrrtiiiieeee yyyyyeeeeeeeesssss!"

"Didn't get full marks in my sex education exam for nothing uuuuuuhhhhhhhhhh!"

Artie came and orgasmed, lied on his bed to catch his breath then smoked a bong.

Afterwards Amy walked back through the rift then went home. At night she had a wet dream as she lied in bed next to Rory.

"Put the cock deep inside me" Amy orgasmed

"Glad your thinking of me" Rory said

"Yes Artie yes!" Amy screamed.

"Fuckin 'ell" Rory said, pissed off.

In the morning they woke up and Amy said "Oh how i want to be rammed by a large cock"

"I'm right here baby" Rory said, "Make my angel weep in your pandorica."

"I said large, Rory, like Artie's" Amy responded, "Even this is bigger than your cock!"

Amy took a Greggs sausage roll and rammed it up her fanny.

For the rest of the day Amy refused to have sex with Rory and taunted him with comments over his small cock and Artie's 'Prisoner Zero sized' cock.

Rory was so pissed of that he went to the local sugery on the next day.

He went to the receptionist and said "I'd like a penis enlargement".

The receptionist laughed and said "Mr Williams unable to please his mrs with his chipolata sized cock..."

"I'D LIKE A PENIS ENLARGEMENT!" Rory bellowed and he paid by card and waited until it was time to see the surgeon.

Hours later Rory was pleased with his surgery - he now had a Prisoner Zero sized cock, and he felt his sex life was going to be back on track.

At night Amy was in bed and Rory entered the room after he had a shower and said "I've been thinking, how'd you like to get freaky?"

He dropped the towell, revealing his now large cock.

"Wow Rory, how much did it cost you? Artie got his for free" Amy said.

"You know what? Go fuck yourself!" Rory responded, causing Amy to laugh.

"Cheer up Rory, yours is 0.5 centimetres bigger, fuck me as hard as you can daddy!"

Amy spread her legs and Rory jumped on the bed and climbed on top of Amy and he fucked her like there was no tomorrow.
