What do you think he's gonna say?

Sam sighed and Shrugged, "Fine.... but nobody can know!" Sam said removing his shirt, Hannah almost instantly went red at his tall and lean form, "Oh my god..." she mumbled, "What?" she assumed her normal prickliness "Never mind just get on with it!" Sam unbuckled his belt and pulled down his jeans. standing in his Calvin Kleins.

Sam Sighed as the awkwardness began to swelter, Hannah simply stared at him in a dreamy haze "Hey!" he said clicking his fingers at her "Your turn...." Hannah's nerves seemed to get to her as she stammered out her words "T-That wasn't, M...Mentioned I shouldn't' have to...." Sam crossed his arms, silently watching and waiting for her to hear what she was saying, "I am sorry.... this isn't gonna work if I don't strip so...." Sam rubbed his eyes "It doesn't have to work at all, I told you that this does not have to happen Hannah"
"...And I said that I wanted you to do it, so shut the fuck up and let me get undressed!" Sam watched as Hannah began to unbutton her pyjama top, she was clearly very shy but tried to make as much Eye contact as possible "This is really weird....." he thought to himself, as she took off the top and threw it on the bed, no matter how shy she seemed Hannah took off the Pyjama bottoms more slowly and more sensually than he had ever seen any woman take off their lower clothing.

Sam found himself stunned by his Foster sisters form, her slim and flat stomach, the natural shine of her skin was dazzling, her small black bra indicated that a Pair of Perky B cup breasts hid under them, her hips where much wider than the rest of her body, in fact her ass was quite impressive and her long mousy brown hair reached down to her upper back which crowned her cute Face.

Sam was shaken out of his haze by Hannah "Hey, whose staring now asshole.... can we just, you know, get on?" Sam nodded walking over to the bed, Sam heard Hannah gasp as he faced away from her, Sam turned "What?" Hannah's tone changed a little, she seemed concerned "What, what is it?" Hannah approached circling around him and looking at his back.

"Sam what the fuck happened to you?" Sam felt her hand touch his lower shoulder blade and as she did, that unbearable pain shot right through him, the memory of that day.... that day that he lost a part of himself.... "Don't!" Sam said pulling away quickly, "Sam, why do you have all of those scars on your back?" Sam tried to hide the fear from his face but it had clearly showed, as Hannah gave him a concerned look "Sam what did they do to you?" Sam pushed his fear away, managing to regain his self control "Hey... lets just continue, huh?" Hannah was very worried, she kept trying to get another look but he evaded her attempts "Sam, What the hell, it looks like somebody ripped half the skin off of your back off, please tell me what happened!" Sam shook his head "Maybe.... but not here, not now..." Hannah sighed "Well, if you tell me we don't have to do... this" Sam shook his head "I would rather carry on if you don't mind" She seemed worried still but nodded in understanding, "Okay, come on then...."

Hannah took Sam's hand and led him to her large bed, her hand was soft and so was the linen on her bed, "Hannah what if somebody catches us?" She got on her stomach, taking one of her pillows and placing it beneath her "I had the room sound proofed for my seventeenth, and the door has a lock on it..." Sam looked down at Hannah's form, her ass faced him and her black Panties almost mockingly showed just enough to tease an idea of what was underneath.

Sam hesitated "Sam please, the longer you take the longer this will be drawn out" Sam sighed getting behind his sister "You promise that this will be the only time this happens?" Hannah paused "S-sure just start when your ready" she quickly mumbled.

Sam pulled down his Underwear, unleashing his semi-hard cock, Sam then reached for Hannah's waistband, he was so conflicted, he didn't know how to feel... Hannah was beautiful and he trusted nobody more, but it all felt wrong especially after what he had done this morning.

Sam pulled down Hannah's Panties slowly, revealing her perfectly round ass and her now glistening shaved slit. Hannah's breathing began to become heavy, "Don't stare just put it in..." Sam took his now fully erect dick in hand and directed it at Hannah's pussy, knowing that her wetness would allow for easy entry.

Sam pressed his head against Hannah's entrance, she gasped and he exhaled as he slowly began to enter her "Oh it's so fucking big!" she said to herself as Sam slowly slid in further and further, Sam felt just how tight she was and had to stop, Hannah moaned and stirred "That's all of it right?" Sam shook his head, "No Its just.... really tight!" She tried to hold back her arousal "This is way more than earlier..." Sam felt her Walls begin to quiver and spam as he began to slide in more and more "Oh Jesus Christ!" she practically cried out as orgasm came over her, one that was very clearly her first, Sam's Shaft finally hilted fully in Hannah's cunt.

Sam paused as she recovered from her orgasm, "Are you okay?" She hushed him as she tried to get used to the sensation "it's so filling...." Sam didn't move a muscle as was the plan. After some time Hannah seemed to regain some composure, Sam was finding t difficult to remain still, especially after her walls constricted around his cock, "Hannah I'm gonna pull out" she cried out "No, don't!" Sam couldn't just stay still, he wither wanted to fuck or just pull out, "Hannah I'm gonna cum if I don't move or pull out, and the deal was to just penetrate..." Hannah sighed and quietened "Well... why do't you just move, a little" Sam wanted to say no but was too aroused to care "O-Okay..."

Sam began to slowly pull out and them slowly push back in. Hannah moaned deeply, she mumbled obscenities to herself as Sam tried to keep control over himself, "Faster" she said quietly "what, but you-" Hannah sighed with annoyance, "I'll do it myself!" Hannah began to move her large ass backwards and forwards, her hips gyrated faster and faster, "Hannah we need to stop, or I'm gonna come" Hannah didn't listen speeding up even more, She moaned louder and louder until she was practically screaming "Oh, fuck me you cunt, fuck this Virgin pussy!" she Orgasmed a couple times as she took his member, Sam felt his Instinct begin to kick in, he took hold of Hannah's hips and began to slam his dick into her pussy "Fine!" Sam began to rigorously pump into Hannah as she bit down into her pillow, Sam's Shaft began to spasm, he knew that he had to pull out else she would get pregnant, and finding out that his Foster sister was pregnant with the Third seed of evil was not on his agenda.... at least not yet (;

Sam quickly pulled out shooting his Load all over Hannah's back, Sam groaned as his last rope of cum spurted on Hannah's back, "W-what the fuck!" shouted Hannah, remaining still to stop the cum from getting on her bed, "Why did you Cum on my back for!?" Sam caught his breath "Well, I have to come somewhere, would you rather I cum inside you!?" Hannah didn't answer but made a strange face.

"Go and get me a Towel from my bathroom please, I don't want to get it on my bed, the mid will tell Mom when she washes the sheets" Sam got up putting his underwear back on, he fetched a towel from Hannah's bathroom, Which for some reason she never used, Sam walked in to see Hannah sucking some cum off of her finger "What are you doing?" Hannah jumped turning as she did, "Oh for fuck sake!" she exclaimed gesturing for the towel, Sam laughed as she frantically tried to clean the cum off of herself and now her sheets.

Sam yawned as he looked at Hannah's clock, "Forty past Ten, I should go to bed!" He said as Hannah continued to try and clean up the cum, Sam knew where she kept the blow up bed, and in moment he had it ready, "Are just going to go to sleep, why don't you try and help!?" Sam yawn stretching "Naw, Its your own fault, you do it" Sam walked over to her bottom draw taking one of her covers and slumped down on the pillow "Your such a dick!" Sam almost immediately fell asleep.

Hannah sighed, looking over to check if he was still asleep she dabbed her finger on the cover and tasted some more of her Foster brother's Cum.
