* * * * *
Sunday morning came, as all Sunday mornings must. I woke up with Susan in my arms, her head lying on my shoulder. I turned to look at the clock, and it was nearly noon. Boy, the alcohol and sex sure had wiped us out. I felt pretty good though. Not hunger over – much.
We didn't know what time mom and dad would be back from the shore house. It was only an hour drive, but when they returned often depended on whether dad had any briefs to prepare for work the next day. In any case, we couldn't roam around the house naked or anything.
I got up to use the bathroom and upon returning, just had to admire Susan's body in my bed. Sister or no, she was quite the picture. She was on her side, her face hidden from my view and facing the other way. Her body twisted in a way that her ass was facing me, but I could still see her stomach and most of her breasts. Sis was wearing a short T-shirt and thin, white cotton briefs. The shirt just covered her mouth watering tits, and her nipples appeared to be a little stiff, sticking out noticeably through the fabric. Her uncovered stomach was not just flat, but defined in the way she was turned, with tight muscles – the result of sports and exercise. It was gorgeous.
My sister's legs were long and feminine, though again in an athletic way. They looked both powerful and incredibly sexy. The back of her shapely calves was marvelous. Her ass was round and firm, a perfect bubble butt.
FLASHBACK My cock fully penetrating Susan's gorgeous ass. My little sister sucking my fingers – in intense heat – impossibly horny. Begging me to fuck her harder, to fuck her ass. Her eyes opening wide and closing tightly as she reached new peaks of ecstasy.
Watching her on her side, cuddled up in my bed like a big child, I began to feel some pangs of regret, of guilt. No matter that the sex had been incredible and that Susan had begged me for it. She was still my little sister, and I didn't want to take advantage of her.
But when she rolled over, all those thoughts disappeared. Now facing me with her eyes closed, one graceful breast peeked out of her top. It was tan around the rounded bottom, yet lighter where her bikini line made its erotic design. This made her nipple seem all the more brown and prominent.
She unconsciously had a finger in her mouth, sucking it lightly. As I approached the bed, her sultry blue eyes opened lazily, and a smile began to make its way across her mouth up when she realized where she way and with whom.
"Adam," she whispered. "Come and sit next to me."
I walked over to the bed sort of sideways, embarrassed by my hard-on and doing my best to conceal it. I sat down with my back to her legs, my hands in my lap to cover up. I turned my head to speak to her.
"Morning baby, " I said warmly, playfully. "Sleep well?"
"Mmmm, yes," she said, stretching out like a cat. Her entire torso exposed, and the T-shirt losing its connection and rising up to exposes her glorious breasts. Oh my aching cock. "It was a fantastic night, wasn't it?"
"Fantastic," I echoed.
Susan rose up on one elbow and looked me in the eyes, beginning to wake more. She smiled at me in a way that I can only describe as loving and cute at the same time. A wide, exaggerated smile that made crinkles around her eyes. As if to say, "Aren't I cute?" Indeed she was.
She reached over and rubbed down my back, then rose up a little more to encircle my waist and rub my stomach. She rubbed up and down my stomach and chest this way, which was making me crazy. I pulled my arms from my lap and leaned back on my hands, my eyes closed. Then Susan must have seen my erection.
"Mmmm," she purred. "My friend is back."
She reached down and rubbed my cock over my underpants, starting at the head and down the shaft. When she got to my balls, she caressed them gently. I could hear from her breathing that my baby sister was starting to get hot again.
"Sue," I protested mildly, "it's after noon, and we don't know when their coming home."
"No, we don't do we?" she answered rhetorically, putting her hand inside the waistband of my boxer briefs and rubbing my already swollen cock head with her thumb and index finger. "Isn't that part of the fun?"
It was difficult to argue, with her hand rubbing down my shaft and cupping my balls. I reached over and gently held the bottom of her left breast. I extended my thumb up and ran it over her nipples, which responded immediately by stiffening and elongating. Sue moaned.
Susan was sitting up, and I swung my body around to face her. My legs were spread over her warm lap. I took both her breasts in my hands and caressed them, playing with the nipples. I quickly wet my fingers in my mouth, then squeezed and circled her nipples.
Then - and this was hot - Sue just looked in my eyes, never taking them off of me, while she rubbed my cock and I rubbed her tits. We must have stayed that way for several minutes, I can't tell. It felt too good. Susan began to sense the stirrings of orgasm from the nipple-vagina connection, because her voice was shaking a little as she opened her mouth to speak.
"Adam," she breathed softly, "this feel so good. You're gonna . . . gonna make me cum just from this . . ."
The hell I was. I moved my body back a little, exposing Sue's crotch. Moving her panties aside with my four fingers, a quickly massaged her clit with my thumb. This broke the dam, and the floodwaters of my sister's orgasm began to pour through.
Susan's eyes opened as wide as saucers. She looked at me in disbelief, that I could make her cum so suddenly, so intensely, so easily.
I squeezed the nipple of her right breast firmly, while my left thumb encircled her engorged clit.
"Oh my God, Adam," she roared. "Oh God in heaven . . . I'm cumming . . ." I thought that she would close her eyes and drop her head, but she didn't. She just kept looking me in the eye as her body shook in climax.
"Look at me, big brother . . . . Look at me while I cum . . . while you make me cum . . ."
Her breathing was erratic and coming in rushes and the orgasm overtook her, but she kept looking into my eyes, which was so incredibly hot.
"I'm cumming now . . . cumming," she continued, her hips bucking up and down on the bed. "I'm so . . . . I can't . . . . I love you so much."
She finally arched her back one last time and settled down. I removed my hands from her body and got off the bed.
"We don't know when they'll be home," I said, "we'd better get ready."
"Wait," Sue said, her voice a low moan. She rolled over on her elbows on my bed, her head by the edge. "Come here, Adam."
