"Hey Dad, what time did Aunt Sue say she'd be here?" Aaron yelled from the top of the stairs. He was fresh from his shower, his hair still wet, a towel wrapped around his middle. His upper torso was well muscled, especially for an 18 year old who was not really into sports or body building. The towel tented in front, pushed out by his still erect penis. While showering he had been thinking of his visit a few weeks ago with Aunt Sue, his Father's sister. He had called her in desperation when his car had broken down and he had need a place to stay until it could be fixed the next day. He had ended up staying a couple of extra days, enjoying the well proportioned charms of his Father's older sister, discovering the myriad of sexual pleasures to be found with a mature, Big Beautiful Woman. Yes, he was looking forward to his Aunt Sue's visit and already planning on ways to get them naked and romping together as often as possible during her visit.
"She should be here within the next half hour, if she can manage to get that overweight body of hers any where on time." Aaron's father's voice indicated his disgust at his older sister's weight. An argument several years before and precipitated the breach in their relationship, and Aunt Sue hadn't visited since then. However, after she and Aaron began their incestuous relationship, she decided a visit was in order. Both Aaron and Aunt Sue were determined to continue their sexual relationship whenever and where ever possible .Aaron got hot and excited just thinking about burying himself in his Father's sister while under his Father's roof. His Mother and sister were going to be gone for a few more days, visiting his Mother's sister in Reno. Aaron planned on skipping a class or two while his Father was at work so he and Aunt Sue could continue screwing each other's brains out.
Aaron quickly dressed then hurried down the stairs as he heard a car door slam in the driveway. The doorbell rang before he was all the way down, and his Father answered the door himself. There she was, lush curves showed off in a bulky knit sweater of light gray, capping a flared skit of a darker gray, her full legs shown to advantage in off-black stockings, which Aaron knew would be held up by a sexy garter belt. If Aunt Sue had bothered to wear panties, he knew they would be lacy and sexy as hell, but also knowing Aunt Sue, there was a good chance she was not wearing any panties, leaving her hairy labia exposed if any one should have the opportunity to check. Aaron knew he'd be checking just as soon as possible.
Aunt Sue enveloped her brother in a big hug, pulling him close, pressing the shorter man's face into her ample bosom. Over the top of his head she spied Aaron and gave him a wink, pressing his father's face even tighter to her, squeezing him once more in her fierce hug before releasing him.
"Aaron!" she exclaimed, as if just seeing him. "Come give your Auntie Sue a big hug." She opened her arms wide and welcomed him into her embrace, recognizing his delight in seeing her as he pressed his erection into her as they hugged. Using his body to partially block his Father's view, Aaron pressed his fingers into his Aunt's buttocks, enjoying the feeling of the fleshy mound in his hand. His Father had picked up the suitcase she had set down earlier upon entering and was already beginning to carry it towards the stairway. Aaron used that moment to reach under his Aunt Sue's sweater to pinch a full nipple between his thumb and forefinger, twisting it, enjoying the look of pleasure on her face, her quick inhale of breath as he rocked his erection into her once again before releasing her and turning to pick up her other case, both of them following his Father up the stairs. Aaron made sure to put her in the middle so he could watch her full ass, and thick legs as she climbed the stairs. Watching the twin moons, he thought about pushing his penis between those cheeks and burying his long, thick cock in her tight ass. A small groan of anticipation escaped him and Aunt Sue glanced behind at him, checked that her brother was still ahead and not paying any attention to what was going on behind him, and reached behind and pulled her skirt up in the back, briefly treating his hungry eyes to a view of her gorgeous big ass, exposed because the only thing she was wearing under her skirt were her stockings and garter belt, just as he had hoped. She winked once more, before lowering her skirt and reaching the top of the stairs.
Aaron's Father opened the door to the bedroom at the far end of the hallway, right next to Aaron's room. The room directly across from the guest room belonged to his sister, the other room, next to hers was his parent's room. There was a bathroom connecting Aaron's room and the guest room, one that opened into the hallway, as well as having connecting doors in each of the bedrooms. Aaron smiled as he thought of them using the bathroom as their passageway to pleasure every night.
"Thank you Charlie" Aunt Sue said as her brother placed the suitcase he was carrying on the king sized bed that occupied the middle of the large guest room. She knew he hated being called "Charlie," much preferring the more formal "Charles." Charles grunted his acknowledgment and told her that they had reservations for dinner in a couple of hours, and he would be in his study going over some paperwork until then, assuring her that Aaron would be happy to help her unpack and find anything else she might need. He walked out of the room, considerately closing the door behind him.
Aaron and Aunt Sue listed until they could hear his heavy tread going down the stairs. Aaron was the first to speak. "Any thing I can help you with Auntie? Any thing you need?"
Aunt Sue walked over to the edge of the bed and bent over, laying the upper half of her torso on the bed, pulling her skirt up and over her ass as she spread her legs wide. "Yes, Aaron, your old Auntie has this terrible need to have her little nephew's cock pushed all the way up inside her." Aaron was already unzipping his fly and quickly pulled his penis free as he walked up to her body and positioned himself behind her. He aimed his fully erect penis at her exposed labia and pressed between the twin lips, once again overwhelmed by the wetness of her, the feel of his cock as it slowly buried itself in her, resting once he was all the way in; taking deep breaths to calm his excited body down before he shot prematurely into her. Once he felt himself to be under control he began slow, deliberate strokes, pulling all but the very tip of his penis out of her quivering vagina, before he would begin his slow, torturous decent back into her. Sue moaned in pleasure, rocking her body in harmony with his strokes, her body responding to the teasing.
Aaron stated moving quicker and quicker, thrusting harder and harder into her as he felt her body respond. He started whispering to her as he continued stroking in and out, telling her that this was just an appetizer to what he had for her, telling her how he was going to use her body for his sexual pleasures during her visit. He described how he was going to titty fuck her again, shooting his cum all over her face, how he was going to go down on her, licking and sucking her pussy and clit until she ejaculated all over him. As he told her what was in store for them, he felt her body shivering, responding to the fire building in her and knew her climax was close. He quickened his strokes, feeling his own orgasm building. The sudden tightening of her vagina around his penis as she climaxed sent him over the edge and he gave a muffled moan as he shot into her. She continued rocking, squeezing two more bursts of cum from him before he collapsed across her bent over body, hugging her, allowing his penis to shrink back to its normal, unaroused state before he pulled out, giving her wide ass a quick, hard slap as he backed away from her.
Aunt Sue stayed bent over, her legs still spread as she basked in the lingering pleasure of her orgasm. Aaron quickly sat down behind her, spread her legs a little more, used his fingers to part her labia and began flicking his tongue over her clitoris, then licking her dripping pussy, tasting his own cum on his tongue. Sue moaned her encouragement as he sucked her unsheathed clit. Aaron knew another orgasm was not far away. He licked her faster, deeper, harder until she once again came apart in ecstasy.
Satisfied that he had made her feel "welcome" Aaron stood, readjusted himself back into his jeans, gave her ass a quick kiss and another hard slap, then told her she needed to get unpacked. "It wouldn't do for Dad to wonder what we've been doing if he comes in and sees you haven't unpacked yet."
Sue stood up, pulled her skirt down over her ample thighs, and turned to the cases sitting on the other side of the bed. She quickly had her neatly stacked lingerie in the dresser drawers, adding her favorite sachets to the drawers. Her dresses had been packed on hangers and it took only a minute to hang them all up neatly in the closet. Aaron watched her set out her her shampoos, body lotions, and the few cosmetics she used. "There, Sweetie. Now how about helping your Auntie with one more thing before we go down and disturb your father." Laughing, she pulled up her sweater and unhooked the front closure of her bra. Her huge, pendulous breasts sagged but the nipples, huge and rosy, were the stuff of his fantasies.
Aaron buried his face in her breasts' fullness, inhaling the musky, slightly sweaty sent of her body. He knew what she wanted. He remembered how he had discovered she liked having him play roughly with her breasts, sucking them hard, biting the nipples hard between his teeth, pulling and pinching them as he twisted the nipples. At first he had been reluctant to hurt her like that, but once he realized that she got off on it, craved it almost as much as she craved having him inside her, he too enjoyed using her breast that way. She especially loved it when he used them roughly as she was reaching her orgasm, pinching or biting as hard as he could when she reached the pinnacle of her climax, sending her over the edge in a frenzy of passion and pleasure, heightened by the pain.
