My Sisters BF

It was this past Summer that my older sister invited her College Boyfriend to join us for our 2 week vacation down in LBI, NJ. My sister (Jen) is a Junior at WVU and started dating this guy (Derek) about 2-3 months ago. The family has never met him, because he lives in Maryland and they met after Christmas break. I’m Jen’s younger sister and I’m 19 and going into my sophomore year of college. I’ve dated a bunch of guys but nothing serious. I like to remain single on Summer Break, to weigh my options and play the field. I love meeting new guys especially when it comes to sex. I’m always excited to see what the guy is sporting in his pants. I love the surprise of seeing new dicks.
Dereck arrived 2 days after my family did and I was at the beach with my younger brother and his friend. Jen arrived to the beach with Dereck and he looked just like he did in his photos, just taller and more muscular. He was very cute and seemed a bit shy. My sister had bought him a new bathing suit while we were at Ron Jon Surf Shop and he was wearing it. They were like board shorts that sufferers wear. My sister and “D” aka Dereck head into the ocean for a swim and I’m laying down on my blanket tanning my back. When they return both Jen and D sit in the chairs in front of my blanket. My sister is telling D how much she has missed him since May and can’t wait to be with him later that night. I’m trying not to listen but it’s almost impossible not to. D tells my sister that he to can’t wait to be alone as well. As I begin to roll over onto my back, I get a direct view of this enormous dick almost poking out D’s bathing suit. I could not help but stare at the size of this thing. I deliberately changed my mind and decided to remain on my stomach and act like I was now reading a magazine I had. I just continued to admire the size of his cock the entire time they we’re making small talk. The more they talked about hooking up that night, the larger D’s cock got. At one point he tried to adjust himself and I’m pretty sure he saw me glaring at his fat cock. He made no attempt to pull his shorts down, if anything, he sort of adjusted himself so I could see more of his junk! As they continued to talk about sex and stuff, D started to leak precum and I could see a nice long stream of it just dripping into his suit. At that point I needed to cool off so I went for a swim. My bikini is cream colored. Unlike my sister, I inherited my moms large chest. When my bikini gets wet, it’s easy to see the outline of my nipples as well as the mound of my pussy and my thick pussy lips. When I return to my blanket, I see my sister and D had taken it over so I just cop a squat on one of the chairs. I wanted to see if D was true to my sister or just another Fing Scumbag. I purposely sit with my legs slightly open so if D wanted to he could checkout my entire snatch. I made sure my crotch was directly in front of him. When I saw him looking, I quickly pulled the bikini away from my pussy as to readjust and deliberately pulled to to the side so there was a full view of my naked lady parts. I knew it! D locked on and did not turn away like a gentleman should have. I played with my bathing suit both top and bottoms for a few minutes and D had laser focus on everything I was doing. I told them I was going back to the house to rinse off and to get some lunch. Jen said she was going for a run first and would meet us back at the house. My brother and his friend went to the amusement park. When D and I got home there was note from my parents that they we’re meeting friends for lunch and would be home for dinner. I head to the outdoor shower to rinse off and to get out of my wet bikini. While showering, I continue to notice that the sunlight that peeks through the smaller gaps between the wood slats continually go light to dark. I immediately figure out that D is outside trying to get a look at me naked. I finish my shower and wrap a towel around me and head into the house. D is in the kitchen having a beer and asked if I’d like one. I said sure. I hopped up onto the kitchen Island in just my towel because I did not want to get the wicker barstools wet. The island is made out of granite. As I’m sitting there D hands me a beer and said, I saw you staring at my cock at the beach and you got me really hot and super hard. I was at a loss of words that he would be so direct and forward to someone he had just met. I turned the conversation around and said, I noticed you looking at my big tits and I also saw you checking out my pussy when I adjusted my bottoms. D replied that he thought I did that to repay the favor. I just sat there and stared at him and before you knew it we both bust out laughing. D told me he has not been laid for about 7 months now and that him and Jen only fool around a bit because she is a proper girl. I sort of knew that about my sister, but I did not know that would continue for over 3 months.
We are now on beer #2 and my towel has become slightly undone. D mentioned that one of my breasts was popping out and I thought that was very polite of him to tell me. I asked D if he was outside the shower before when I was showering? He said yes. I asked him why? He said he took it as a possible invitation but when the door was locked he realized he was wrong. I asked him do you think you Jen will last? He said honestly he did not because he is very sexual and she is not.
I asked what sexual act he likes to do on women? D said he loves to eat pussy! I got off the island and said follow me. We went into my brothers bedroom and I lied down spread eagle on the bed. I said to D; let’s see what you got. D ate my pussy like a fucking porn star. I was so Fing wet and approaching my 2nd orgasam. I could not take it anymore. I told D to fuck me with that huge dick of his. D drops his suit and there is 8-9 inches of rock had cock about to stretch my pussy out. D pins my legs behind me and enters me in 1 shot. It felt like burning coals. He must have known I like it rough and like to be dominated. He fucked me silly. He got me on all 4’s and fucked me balls deep, His balls were so big and heavy that he gave me another orgasam with his balls hitting my clit. I’m soaking wet now and D pulls out and puts his enormous cock in my ass. I’m like WTF! He eases it in until the entire shaft in completely in my bottom. He bangs my ass until I have an anal orgasam and D drops a Monster Load in my bum. I literally could feel my ass tank being filled to capacity. When D pulled out I just collapsed in my brothers bed. D immediately went to shower and I went to my room to change. My sister returned about 30 minutes later and wanted to know if we wanted to go out for drinks? Later that evening my sister thanked me for keeping D company on her run. I told her it was my pleasure. Meanwhile the entire time out I had to change my panty liner at least 3 times because of D’s enormous load. I never told my sister and her and D did not last much longer. I don’t see him either, it’s a sister thing.
