Waking up with wood again.

The sound of a dog barking outside wakes you up with a start. As you do so you end up coughing and spluttering, as in your sleep you had been spooning Rachel from behind and got her hair in your mouth. Once you stop choking on her hair it becomes apparent that once again this morning you have awoken with a severe case of wood. This time it is not due to Rachel hotdogging you, rather your length is still buried in her incredible bubble butt. 

Her skin is warm and soft to your touch as you rub her arms gently, in response a soft sleepy moan escapes her lips. She looks so beautiful lying there on the bed that your member lurches in her tight tunnel and demands that you pound her ass like there is no tomorrow. However you prove to yourself that you're not entirely governed by your 'other head', and instead opt for wrapping your arms around her narrow waist and planting a kiss on her forehead.

You stay like this quite a while, entertaining yourself by watching the still sleeping Rachel's huge breasts rise and fall spectacularly in time with her breathing. Faint, happy little moans escape her lips and judging from the smile on them, and the way her nipples have visibly hardened considerably more than normal, you can only guess she's that having a rather nice dream right now.

"Are you thinking of us, honey?" You ask softly, not expecting an answer from the sleeping beautiful brunette, but she does murmur softly in her sleep.

A quick glance downwards reminds you that you went to sleep last night after Rachel had blasted your chest with her cum. Dried, crusty semen covers a large portion of your upper body, which you poke at with a grimace. Deciding that getting cleaned up is the first priority of the day you place both hands on Rachel's narrow waist, and with a groan you slowly extract your stiff member from her tight ass hole. Her dark tunnel is still hugging it in a tight, vise like grip, threatening to cause you to once again explode in her bowels. Gritting your teeth and trying to keep quiet to prevent your girlfriend from waking up, you finally manage to extract your entire shaft and your bulbous crown from Rachel's widened bung hole, caused by accommodating your member in her tight tunnel for the past few hours. 

Despite some faint moans and murmurings Rachel managed to stay asleep during your removal from her heavenly behind. With a quick kiss on her cheek you carefully get yourself out of your girlfriend's bed. Moving carefully and quietly around her room you locate your trousers dumped haphazardly in a pile with your other clothes. Retrieving your phone from the trousers' back pocket, and checking the screen you find out that the time has is 8:35 am.

With an amount of grace and stealth normally reserved for a ninja you make your way across the obstacle strewn floor to your overnight bag. Rummaging through the bag you pull out your towel, toiletries and a pair of underwear. Considering the bathroom is only a few feet down the hallway from Rachel's bedroom you consider it safe to make the short journey clad only in your underwear and with the towel draped over your shoulder.

Less than a minute later you are ready to move and with a last longing look at the sleeping brunette on the bed you turn the door handle and exit the bedroom. It quickly becomes apparent that you will be unable to reach the bathroom unnoticed. The person who you're run into is also the one you would have rather avoided considering the events of mere hours ago.

"Er, morning John". Amy says awkwardly from the top of the staircase. 

"Morning Amy. Did you enjoy your party? How's the head?" You ask her. Rachel's little sister is wearing a loose fitting jersey of the local sports team, and a matching pair of shorts. The sports top hides her curvaceous body, but the shorts show off her lovely long legs and once again you are reminded of just how similar looks to her stunning elder sister. 

"Er,yeah....it was great thanks". Her body language is one of discomfort, and she seems unable to look you in the eye. Her gaze roams over your exposed toned torso, and as you catch her checking you out her face turns a bright shade of crimson.  

"Mum is downstairs starting to knock up breakfast for everyone in a few minutes. She asked me to see if you and Rachel were up yet". Amy continues after a long and awkward silence, still looking anywhere but your face.

"Rachel is still sleeping, and I'm going to jump in the shower quickly. If you see your mum before I do thank her for me, please". You say, while thinking that her current demeanor reminds you a lot of Rachel when the pair of you had shared an awkward moment or threatened to get close before you found out her secret. 

"She's making some pancakes and sausage sandwiches so they shouldn't be too long". Amy states, looking like she would like nothing more than this conversation to end.

Luckily for her you decide to grant her request. "Thanks, I'll see you downstairs in a few minutes".

"Sure. I'll knock on Rachel's door in a sec". Amy says, before making her way across the hallway to her room.

Using a remarkable amount of restraint you avoid staring at your girlfriend's little sister's peachy behind as she walks away. Instead you make the short journey to the bathroom. After using the toilet and having a shave, you turn on the shower. When the water is warm enough you remove your underwear and jump in the shower. You spend quite a while washing, and enjoying the simple pleasure of the hot water pouring down onto you, soothing your aching muscles.

You detect a faint flicker of movement behind you, but before you can react a pair of arms wrap themselves around your waist and a very large pair of breasts press themselves up against your back.

"Room for one more?" Rachel purrs in your ear loud enough to be heard over the spray of water.
