I woke up again, after fucking my sister for the second time. I looked at the clock, and this time it read 11:37 a.m. I was still in their bed between Becky and Tammy. My sister Becky was nestled under my left arm, her head resting on my chest. Tammy had rolled off a little to my right, her back turned to me. She was curled up with her knees high up, almost in a fetal position. Despite the more obvious heat and brightening sunlight, she looked cold. Seems like women always get cold when they sleep. I glanced over her skinny body. I could see her bony back bones poking out of her skin. She was more athletic than Becky. Glancing down I could see her square hips and butt crack. There was something boyish about her figure like that which I found alluring, and the way she looked vulnerable too. Gently, I reached out and pushed my arm under her hip and pulled her closer.
She woke up immediately. She began began to stretch and moan a little, turned to look at me. "Cold?" I asked softly. She nodded and moaned out a little, "Mmhmm," in a cute way while she rubbed her eyes. Beck stirred on the other side, but didn't wake up. She rolled away onto her other left side, freeing up my left arm. Taking this opportunity, I used my left arm to envelop Tammy. I was still half-asleep, but I wanted to admire Tammy. After last night and earlier in the morning, I really did feel close to her. And she looked beautiful in the morning light. She accepted my embrace but at first didn't respond much. I hugged her close, almost squeezing her, then pulled back to kiss her shoulders. Again, she was very different from Becky's soft roundness. Tammy was more angular, her skin paler. I kissed and kissed, moving from her neck to her shoulder and back.
My dick was still flaccid, but as she stirred and began to writhe her butt crack touched my cock and it began to quickly wake up. Soon I had a full erection, bumping up against her butthole and pussy. I became more and more bold, kissing her back down along her bony spine. I could tell she was fully awake now as she stretched again, cat-like, and looked back at me smiling.
"Warm me up, little brother," she whispered. I loved that she instinctively adopted the moniker Becky used with me. She rolled onto her belly, momentarily pushing her butt out seductively. I knew what she wanted. As she got comfortable I climbed on top of her. I kissed her neck and shoulders again, softly. I would tease her, making my way down her back slightly, only to suddenly pop back up to her neck, then make my way down a little lower. She responded deliciously, moaning as I made my way down and giggling when I popped back up to tease her. The entire time my hard cock was nestled firmly in her butt crack, tickling her butthole. As my mouth made its way down her back, I slid off her slightly and let my hard on glide back and forth over her asshole. Now as I curled my body to kiss her lower back, the tip distinctively found her pussy. I could tell by the wetness. I let my cock tease her cunny a little while I kissed her back more intensely, and she spread her legs slightly to give me access.
But I wanted to do something else. I ignored my anxious morning wood and slid further down, kissing her lower back and now her hips while massaging her butt cheeks. She seemed to really enjoy this, moaning while I grabbed and rubbed her butt. Tammy was one of those girls that is skinny but still undeniably feminine, with small but curvy breasts. Likewise, her ass was small but had a cute little curve just under the butt cheeks that gave her an unmistakable femininity. So I admired her body as I rubbed and squeezed, and she began to moan more and more. I didn't want to tease her too much, though, and I moved on to her pleasure.
I kissed each butt cheek again, then gave each a soft bite. I opened my mouth wide and used my teeth to grab a big chunk of flesh, but instead of biting down I let it gradually fall out of my mouth, ending in a little nibble at the end. This made her giggle and she looked back at me. I thought she looked a little surprised, but she didn't say anything. I did it again and she closed her eyes and turned to face forward again. She reached out and grabbed a pillow, pulling it under her face and neck and burying her face into it. I nibbled her butt cheeks a few more times, moving down and down, toward her upper thighs as well. Now she was really loving it, moaning and writhing around. I had a full view of her asshole and pussy. She had a pretty brown butthole which contrasted with her pale skin, covered in her dark hair. Her pussy was also different from Becky's. Becky had a girlish pussy, puffy and soft. Tammy's pussy was bigger. Longer and wider, with more pronounced labia. Her clit was more pronounced. As I lingered admiring it, she raised her butt again invitingly. I didn't want to keep her waiting, but I wanted her to get comfortable for what was coming. I took the pillow from under her face and moved it down under her hips, leaving her raised up for me to work. As I did this she gave a little giggle and Becky woke up.
Becky had been lying on her side with her back to us, and now she turned in a languid stretch onto her back. Rubbing her eyes, she sleepily looked at us. As she took in the view, she smiled and said, "Good morning."
"Good morning, sis," I said, and bent down to Tammy's butt. I kissed each cute pale butt cheek again, then put my face squarely in the middle of her butt crack and kissed her asshole gently. Tammy gasped in surprise. I know she wanted this, but maybe she didn't think I'd go for it.
"Good morning, babe," she said as I kissed and began to lick her butthole. She raised up onto her elbows, and I could see she was excited. As I continued she moaned more and more. Her mouth hanged open in pleasure. She opened her eyes and looked at Becky. "Your little brother is licking my ass, babe," she said breathlessly.
"Hmm, I can see that," said Becky. She moved closer to Tammy and caressed her back, admiring her and looking back at me. Her hand moved up to Tammy's head and she pulled her in for a kiss. "How's he doing?"
Tammy didn't answer, instead moaning and panting with her mouth open and tongue hanging out, her eyes closed. Becky kissed her again and then raised up on all fours, moving closer to me.
"You're a good boy, Samuel. Tammy loves having her ass rimmed." She took her hand and caressed my head gently, then pushed me firmly into Tammy's ass.
I was encouraged by this. I wasn't sure before starting if this was something Tammy even liked, but now I knew that not only did she like it but that she and my sister did this together. Licked each other's assholes. This made me more excited and I began to push my tongue inside Tammy's asshole. The pungent aroma of her anus was intoxicating. The bristly hair around it was filled with it too, and as I licked around outside I played with it on my tongue. Until now both my hands had been on her butt cheeks, squeezing and massaging. Now I took my right hand and moved it under her, Making a thumbs-up, I put my fist under her mound and let my thumb rub her engorged clit. This had an immediate reaction; Tammy grunted hard. I could feel her wetness, and I let my thumb play in and out of her pussy, always returning to her button. By now Tammy was raising up and pushing against my mouth, almost coming up on all fours.
"Yeah. Yeah. Tongue my ass. That's it. Fuck my ass with your tongue," she kept repeating this like an incantation. I was surprised that she was so vocal. In all the time I had been listening in to her and Becky have sex, I had only ever heard Becky's moans and squeals. I was very turned on that I was giving my new sister so much pleasure. I could feel my cock, which had turned semi flaccid as I focused on Tammy, get hard again. I began to hump the bed with my erection, using the motion to push my tongue into Tammy's asshole.
Becky remained on the sidelines. After pushing my face into Tammy a few times, she had returned to her lover's body. She kissed her back and caressed her. She moved up to Tammy's face and kissed her a little, sucking her tongue and then thrusting her own out to play with Tammy's. Then moved back down to kiss her shoulders. All the while she looked at me. She smiled when I looked up at her, then she moved down to caress me. She kissed Tammy's butt on the way down, then moved behind me and rubbed my back and kissed it.
"Good boy, Samuel! That's just how she likes it." I felt her hand reach under my chin and she pulled my face away from Tammy's pulsing ass. She pulled me in for a deep tongue kiss, tasting Tammy's ass juices on my mouth. But she didn't interrupt us for long. Giving me a smile and glancing at what I was doing with my hand on Tammy's pussy, she leaned in and gave Tammy's asshole a little peck. Then she pushed my head back in.
