"Well... Sunny... we're alone for sometime and I've- I've always wanted to know what it's like to get knocked up." She blushed brightly. You laughed. "Really, cousin, already? I haven't even seen you naked yet!" She looked up with a cheeky grin. "Behave yourself and maybe you will." You grinned and unbuttoned her trousers, before pulling them down. You pushed her panties to the side and looked at her clean pussy. You licked your lips and fingered her slightly, but she gasped and yelped. "Put your thing in there first, before I come to my senses!" You stood up and realized how taller you were than her, and decided to intimidate her. Just a little. "Samantha, you really are an amateur, aren't you? I just came, and I need a few minutes to recharge..." Samantha nodded slightly, as if it were obvious. "But, you can speed up the process by "putting on a show...". You smiled as she was taken aback. Her expression turned mischievous as she muttered "Sure..." and began unbuttoning her top. She cast it aside and motioned for you to sit on the couch. She took off her shirt and threw it at you, exposing a bra covering her small tits. You caught the shirt and she jumped on you as you cast it aside, unbuttoning your top. Samantha pulled off her panties and threw them into your hand, before taking a breath and undoing her bra. She pulled it off to become fully nude and froze for a moment, to let you gaze at her, before you clapped a few times. She then awkwardly began to dance and you could feel your member grow. To get the most out of it, as she closed her eyes, you placed her undies over your dick to hide it. She mainly waved her arms and body, and span around slowly, so the whole thing reeked of amateurism, but you loved her and loved everything she did. As she ran out of things to do, you beckoned her over. She got ready to sit on your cock, but you placed a hand on her rear and whispered "Not yet, baby... let me play with you a little..." You caressed the slight curve of her breasts while your other hand massaged her rump. Your first hand came down and toyed with her pussy as she moaned. She had a lot of mental strength, clearly, as she quickly looked at you crossly. You chuckled and threw her panties (and bra) off your boner and let her see it in all its glory, before helping her onto it. She slowly slid down until she hit your base and looked at you. "I go horse-riding a lot, so we won't have any... problems."
"Horse-riding?"
"You're gross!"
"You're just making me horny, you sexy beast." You helped her ride you a few times before you both decided it was too much trouble. Wordlessly, you turned her over, so she was standing on the ground and had her hands on the couch to support her as you fucked her doggy style. As you pumped, you voiced your concerns: "Samantha, what really, really sucks is that I can't see your lovely chest. Not that I'm saying anything about this pretty thing here though." And you slapped her ass, which you had been caressing as you pounded her. She giggled midst moans and asked if you could just put her on the floor, as neither of you would be calm enough to wait until you had a bed to fornicate on.
"Sam, it'll be pretty rough; poor quality wood and all that."
"I know, just do it!"
You withdrew from her tight tight pussy and laid her down. Then, you clambered over her and gazed at her cute body before you took your member and slowly fed it into her small hole. Even now, you couldn't wait to cum into her as you felt your rod enveloped by her flesh. The cavity was narrow, but it felt right. She too, quivered, just like the first time and you resumed fucking her. Her legs came up around your back and she pulled you in. You fucked her harder and pushed down on her tits to support yourself. Near the end, you managed to kneel down for a kiss and it wasn't long before you fired inside of her, not caring if she got pregnant. You fired again and you pulled out and lay beside her. The two of you remained, still except for your deep breaths. Then you laughed and kissed. You helped her up and slapped her rump and said "Perfect. That was perfect! You were lying weren't you? You HAVE done this before!" You grasped her buttock and squeezed hard. Her eyes widened as she laughed. "That tickles! What do you want to do next? It's your turn, after all."
"Maybe we should move Samantha. I think I saw a pervert looking in a few minutes ago." Predictably, she jumped and you laughed before you pulled her back "Kidding! Do you wanna go outside, or stay indoors?"
"What?!"
"You survived this floor: Come on, our garden is awesome; your flowers have bloomed really nicely, or we could go out front: I love you enough that I'd be content seeing you having the best sex of your life without me being a part of it." You faked a sigh of sadness and she looked at you with a raised eyebrow. "Anyway, Sam, promise you'll leave the clothes here. What's life without some risk?"
