I have been with my girlfriend for years but I still like to keep her on her toes. One day while visiting her parents I was downstairs checking the fridge out while she was watching the TV upstairs with her folks, I grabbed my drink but heard her coming and decided to hang back a bit and let her meet me downstairs. She mentioned she was feeling a bit bored and she seemed to be in a really good mood so I tried my luck and pulled her aside into the guest room for a quick makeout session.

Well I've never been good at controlling myself once I started so I began trying to take off her pants, she blocked me and in a worried tone said;

"Look, I'd love to but there's a pipe that goes from here to the room that my parents are watching TV in. They'd hear us for sure"

I shrugged and kept kissing her, running my hand back down to the zipper on her jeans.

"You're sweet to say that but I really think the TV will drown us out. Besides I've been thinking about you all day in that outfit you have on, I'm aching here babe" I half joked as I was denied access to her jeans again by a swat of her hand.

"You wouldn't want to have sex here anyway... I've been here before with...Umm... my ex in this bed" she trailed off, she seemed to know my weakness in that the mental image of her having sex with her sickly looking ex-boyfriend would often leave me softer than butter. However she underestimated me, I would not be deterred this time.

"You're playing dirty... but sadly I must tell you that you no longer have a choice now" I joked as I began to nibble on her earlobe. She laughed and squirmed slightly as I kept her pinned.

"What? why?" she asked.

"Well because now I know that there's a piece of furniture in the house that someone besides me has had sex with you on. I'm very territorial. If I can't be the only one then I have to be the last" I said as I finally unzipped her pants and pulled them off as I kissed her neck. She let out a moan and looked up at the pipe in the ceiling.

"Okay...but try to be quiet" she said.

In a flash I threw my shorts off and climbed onto her, forcing my cock into her as I gently kissed her lips. Once in I began to slowly increase the force of my thrusts, I kissed and sucked her chest as I began putting the full strength of my body behind each thrust. Impaling her repeatedly with my dick, she gripped onto me for dear life and bit my shoulder to keep quiet. At this point the whole bed was moving very slightly each time and she whispers to me.

"Oh my fucking god. I love how strong you are. You're like a jackhammer" I smiled and kissed her

"Yeah? well I think you're sexy" Looking back I sounded really dumb but at this point there was no blood in my brain so I'll give myself a pass.

As I began to cum I kissed her, exploring her mouth with my tongue as I filled up her puss. During cleanup we made sure to look proper, messy hair or untucked shirts had to be cleared up before going back upstairs to continue the visit with the parents. Before walking back up my girlfriend stopped me and asked

"So having sex on that bed was all just for the sake of being territorial?"

"Yeah. I'm similar to a wolf like that. I have to claim whats mine" I said and gave her a kiss and flashed her a grin.
