"Is this weird?" Jenna asked once she and Joey were settled together in the extra bed set up in their grandparents' attic.
The twenty year old brunette was lying beside her eighteen year old brother and the sides of their bodies were touching. Joey was wearing a T shirt and boxer briefs while his sister was wearing an oversized T shirt and panties. It was too warm for much more than that, and they were lying on top of the mattress with no sheets covering them.
"Yeah, I guess a little," Joey said. "But not in a bad way."
The thick, heavily curved girl took her little brother at his word. The two had shared a bed before, but not since Jenna became so thick and busty or since Joey had turned into a young hottie with a slim, solid body.
"Sorry if I take up so much room," the girl apologized. Their bare legs were touching all the way down as they lay there side by side. It might've been weird for most brothers and sisters, but neither one of them moved away to make any space between them.
"Jenna, you know how I feel about you saying things like that," the younger one said in a paternal tone beyond his age. As it was, Joey was the physical opposite of his sister. He was on the tall side for his age, and tightly built as any athlete. He also had a very prominent looking bulge in the crotch of his boxer briefs, something his sister had noticed plenty of other times in their own house.
"Like what?" Jenna pretended not to know what he meant. "I was just checking if you're comfortable."
Jenna was always vexed by her weight. It didn't matter that she had the most beautiful face in their school, with her chocolaty brown hair and ice blue eyes. She was considered fat by a lot of standards, even though there was a noticeable hourglass shape to her curvy figure. With DD tits that looked proportionate to her body, some people deeply appreciated her sensuous beauty and her younger brother happened to be one of them.
Jenna knew Joey hated it when she criticized herself. He'd asked her not to do it in front of him and insisted she was just as good looking as any girl in their school. He always made her feel better, even if she didn't always believe him.
"I'm perfectly comfortable," he retorted, sounding a little irritated.
"Okay, I just wanna make sure. I'm sorry you got stuck having to share a bed with me."
"I don't mind. Besides, it's not like the first time we had to."
"Yeah, but this one's pretty small."
They were at their grandparents' house because of a family wedding the next day. It was too far to drive back and forth on the same day for the ceremony and reception all together, so their mother planned for them to spend two nights at her parents. Joey and Jenny lived with their mother while their father had been absent from their lives the past ten years. Between their mother and grandparents, the siblings were given no choice but to share the bed their grandfather had set up for them in the attic. Neither said a word about sharing a bed until now. As far as their mother and grandparents were concerned, it was like they were still little kids.
Jenna sighed, her misgivings finally put to rest. At least for now.
It was mostly dark in the attic, except for the open dormers that were letting in some air and moonlight. It kept the attic from getting too stuffy, but it was still pretty warm for sleeping. Jenna wished she could've been sleeping naked, which she usually did at home. She knew Joey often did too since she'd seen him a few times in the morning with the sheets halfway off his body. And some of those times, Joey had a long, thick erection that made his sister gasp the first time she saw it. Her little brother's cock was impressive by any standards, and she couldn't help feeling like it was beautiful to look at. He looked so hard, with the slightest hint of an upward curve to his shaft and a deeply ridged dome that looked like a piece of sculpture.
Jenna wished her brother was sleeping naked now. In the semi-dark, she could see the bulging lump in the crotch of his briefs and it made her crave the sight of his actual flesh. She knew it probably made her a freak to have thoughts like that about her own brother, but she already felt like an outcast most of the time because of her body. Joey didn't have the same problem. He was so good looking that even girls her age and older treated him like a prince. He had his father's jet black hair and dark-eyed looks. Jenna had even overheard some of their mother's friends flirting with him when their mother wasn't nearby.
By now, the curvy girl's pussy was tingling with warmth. It was frustrating not to have the privacy to finger her smoothly waxed slit and make herself cum to her shameful thoughts of her brother. This was the only thing that made her wish she didn't have to share the bed with him. But having Joey right beside her made her feel good even if her pussy was begging for more attention than she could give it.
"You know what, Jen?" Joey said, startling his sister out of her reverie.
"Uhh, yeah?"
"I'm glad we get to share a bed while we're here. I wish we could sleep like this more often."
"Really?"
"Yeah."
"How come?"
"I dunno. It just feels nice. You're my best friend. I love you. I guess I just feel better with you here and knowing you're okay and not getting all worried about stuff."
"Aww, Joey, that's the nicest thing anybody ever said to me," Jenna said, turning onto her side to face him. She pressed the fleshy front of her body against his side. The push of her hefty tits against his arm gave her a sizzling feeling all over her skin. Overcome with love, she touched his face like she would a real boyfriend and smiled at him. "You always treated me the best," she added.
"I love you, dummy," he retorted.
Jenna chuckled quietly. "I love you too, dork."
After a minute of staring at each other, the brother and sister tentatively brought their lips together in a kiss. They were both unsure of what they were doing at first, just kissing lightly and exploring the taste and feel of each other's lips. But this went on for a couple of minutes until they started to grow bolder and more at ease with kissing in a way they were never meant to. It was their first time kissing in a sexual way, but neither of them seemed surprised. It felt perfectly natural, like the normal extension of their feelings for each other.
Jenna knew she should be shocked at kissing her brother, but she was dizzy from the searching touch of his lips. She was dying to slip her tongue into his mouth but she was afraid of breaking the spell. Then Joey's tongue started to probe at her lips and she parted them. She cooed dreamily as their tongues explored each other's mouth. Joey was not only a great kisser but also the best looking guy Jenna had ever kissed. It was also the first time she'd ever kissed anyone she in love with and that made it feel like a whole different thing. All the kissing she'd done before this was just for sport with guys who wanted to feel her outsized tits.
