Dogs and cats, sleeping together
From Torg Adventure
"Let's do it doggy-style this time, Nancy." You look her body over. "I kind of want to be able to look down on your ass."
Nancy smiles at the implied compliment as she gets up and kneels on the bed. She turns slightly, so you can see her nice butt.
"So you like my bottom, Max?" She says, wiggling it slightly. "I knew guys liked to look at it, when they thought I wouldn't notice. Or even when I would. It always kind of made me feel sexy. But I'd always get tongue-tied if some boy ever complimented me on it." She looks a little embarrassed, apparently thinking back to one such episode, even though she doesn't seem ashamed at all by being completely naked in front of the cousin that had just popped her cherry earlier. Maybe it was the alcohol, or just the fact that Nancy had known you for most of her life, and thought of you as family first, and a man second. You suspect you were making her reconsider her ranking of you, though.
Nancy stops shaking her shapely ass at you, and proceeds to get down on all fours on her sister's bed. She's in virtually the same position as Gwen was when Nancy walked in on the two of you fucking earlier. Nancy is taller and more developed than her sister, although that wasn't necessarily saying much, given how petite Gwen and her proportions were. Nancy had a bigger chest than her cousin Sam, although not as tall, and a little more feminine in her lines than the sleeker Sam. Despite their differences, having seen all three of them naked, you could definitely tell they were related.
Nancy looks back at you and wiggles her ass at you again. "Come on Max, and doggy me in my kitty!" She giggles, sounding a little like Gwen when she does that.
You get behind her, wondering if 'kitty' is the term that your Aunt Karen raised your cousins with, as Gwen and Nancy both seemed to prefer it. You could ask either of your cousins that, you suppose, but it might be more fun to try to get the answer directly from their mother.
You grab onto Nancy's ass with both hands, squeezing each side with a hand, causing her to giggle again. You've wanted to do that for pretty much as long as your cousin actually had something big enough to grab on to. Her flesh is more yielding than Sam's, having less muscle mass, which wasn't to say that Nancy was fat, or Sam was over-muscled. They both had nice asses, but in different ways.
"You still have plenty of your sperm left, right?" Nancy asks with a little bit of concern as she sees you grab your cock with one hand, your other hand still kneading one of her ass cheeks. "It sounds like you've used a lot of it today. Do you need more time?"
Then, before you can say anything, she starts talking again. "But it we wait, then Gwen and Sam will be back, and they'll want you in them, and then there will be even less for me!" She wiggles her butt again, not to be sexy this time, but to draw attention to her bottom. She also arches her back a little, so that her pussy is presented to you better. "Put it in me and we'll see how much you have left.
What next?
