“Yeah,” was all she said, smiling back.
I decided to take the plunge. “Maybe we could audition for the parts, to relieve each other’s frustrations when needed. I certainly enjoyed feeling your tits the other day.”
“Yeah, I noticed. So did I.”
So she had felt my cock twitch against her ass and enjoyed me groping her. I got up from my chair and sat sideways next to her on the sofa, facing towards her. We both smiled nervously. I reached out and felt one tit, then the other. She didn’t react. I did it again, taking my time this time, gently squeezing them, uncertain whether I felt her nipples beginning to stiffen through her bra and blouse. My cock definitely stiffened a little. After a couple of minutes, I asked if I could undo the buttons on her blouse, and she nodded.
I slipped my hand inside her bra. Her nipple was quite big, and already hard as stone. I heard her breathing change. My cock was getting stiffer in my jeans. She reached out and touched it. She rubbed it gently and it grew even more.
I began to take her blouse off and she leaned forward to let me, then reached behind her to unfasten her bra. I got up and straddled her thighs, facing her.
Her tits were big and heavy, with large dark areolae, the skin already puckered in arousal. Her nipples were large and stiff.
“Wow!” I breathed. She looked up at me and smiled.
I cupped her tits with both hands, squeezing them firmly and pinching her nipples between my fingers and thumbs. She closed her eyes and moaned softly.
“Play with me,” I told her.
She unzipped and unfastened my jeans, and reached into my briefs to release my semi-erect cock. Gripping it firmly, she stroked up and down slowly. It was my turn to groan, as she soon got me fully hard. She sped up, jacking me faster as I continued to squeeze her tits, pinching and tugging her nipples hard enough to make her moan in painful pleasure.
I could barely believe this was happening. I was massaging my own sister’s tits while she was jacking me off, and the whole experience was amazing. I knew we shouldn’t be doing it, but I didn’t want it to stop.
I felt my orgasm approaching far too quickly and slid onto the floor between her feet, so that she had to let go of me. She raised herself up off the sofa so I could push her skirt up around her waist, then she relaxed again, spreading her knees wider. I could see her pants were damp at the crotch. I let my fingers trace a line up her inner thigh, coming to rest against the damp patch. As I rubbed gently, she sighed. I reach up to remove her pants and again she raised herself up to help me.
I was now looking at my sister’s naked, clean-shaven pussy. The lips were moistened and slightly parted. I let two of my fingers gently explore between the folds, and she moaned softly as they probed and then penetrated her. She was already wet inside. Crooking my fingertips to apply a little pressure to her G-spot, I began sliding my fingers in and out of her, slowly at first, but gradually gathering pace. With the fingertips of my other hand I began rubbing her clit in gentle circles, timing the circling motion with the rhythm of my penetrations. All the time I was watching her expression. Her eyes were closed, and she was moaning softly, her hands resting limply beside her.
As I increased my pace, my sister’s breathing became more ragged. She began squeezing her tits and tugging on her nipples with both hands, watching me now as she moaned and writhed with pleasure. I increased the pace of my finger-thrusts and caresses again, and her moans grew louder before turning into cries of ecstasy as her hips twitched and rolled and she came on my fingers. I felt her pussy muscles pulsing and spasming against my fingers, trying to pull them deeper inside her, coating them with her juices as she came and came, until she begged me to stop.
I withdrew my fingers and licked them, as my sister smiled down at me. I liked the taste of her.
“Thank you,” she whispered.
“Now it’s my turn,” I said, feeling a little breathless. She nodded and smiled again.
Getting up off the floor, I removed my jeans and briefs, and straddled her again. My cock was still semi-hard. It twitched as soon as she touched it. A few strokes later it was so hard it was almost painful.
“Your cock’s bigger than Tom’s. Thicker, too.”
She sped up again, watching herself jacking me off. I watched her too, admiring her tits as they jiggled in front of me. I revelled in the sight and sensations of her hand working my cock into a frenzy. A few minutes later the tell-tale throbbing began.
“I’m going to cum sis,” I warned her, and she went even faster, her hand almost a blur. God, it felt amazing. Seconds later I felt my orgasm erupting inside me. Then it exploded up through my cock.
“Oh fuck, Deborah! I’m cumming!” I grunted loudly, as the first powerful spurt hit her full in the face. Her head jerked back in shock, and the second spurt caught her in her open mouth, and down her chin and throat. Several more thick ropey spurts sprayed across her chest and tits, dripping off her nipples in sticky strings. When I was done, she squeezed the base of my shaft and drew her thumb up the full length of the underside, pushing out the last few drops of my cum. She caught the cum on her thumb and popped it straight in her mouth, sucking it clean. I sat and watched her as she cleaned herself as best she could with her fingers, licking them clean and swallowing each load.
“Do you always make this much cum, or is it just ‘cos you got jacked off by your sister?”
“Oh, it’s definitely you jacking me off that made me cum this much,” I said, laughing. “That was awesome. You easily passed your audition sis, the job’s yours!”
“So did, you, bro! So did you.”
“Do you think you might need your frustrations relieving again sometime soon?” I asked her.
“Definitely!”
“Is tomorrow soon enough?”
She laughed. “Hell, yes! I don’t want to wait any longer than that.”
Chapter Two
The following day, as I made my way round to Dee’s, my head was in a whirl again. What happened yesterday was incredible, and I was looking forward to taking things further today, but how would she be feeling? Would she be feeling guilty now, and regretting what we’d done? After all, she had just cheated on her boyfriend with her brother. Okay we hadn’t had sex, but we had gotten each other off. I had fingered her until she came, and she had jacked me off until I came all over her. I don’t know if that technically counted as incest, but it was still wrong, and yet it didn’t feel wrong when it was happening.
But the first thing on the agenda was coaching her through her work-out, which we could do anyway unless she couldn’t bare to look at me today. After that, we would just have to see what happened.
I knocked on the door and when she opened it she was already in her training kit, including the sports bra she wore to try to maintain at least some control over her chest as she jumped around. She said ‘Hi’ breezily, with a smile on her face but turned away immediately, towards the garage, where she works out.
I wasn’t sure what to make of that. Was she just focused on making sure she got her workout done first, or had she decided that anything more was a bad idea. I couldn’t read her.
We got straight into her routine and I worked her hard, so she was soon panting and sweating. It was fun watching her tits bouncing around, as always, but it was tinged with uncertainty this time. I decided I had to test the water.
She was doing push-ups, with her knees on the floor, and I was knelt in front of her, counting reps and encouraging her.
“You know, if you were working out with a low-cut top on, watching you do those push-ups would make me cum in my pants,” I said nervously.
She stopped and sniggered. “If I worked out in a low-cut top, these babies would knock me out cold. Now shut up and let me concentrate,” she said with a grin on her face. “And don’t even think about cumming in your pants. You need to save that up for later!”
Phew! What a relief! We finished off her routine with some slow jumping jacks to cool down, which got my cock pretty worked up as I enjoyed watching her tits bouncing up and down. She watched me watching them, and when we were done she said “I’m going for a shower. Want to join me?”
“What do you think,” I replied, already stripping off my shirt.
In the bathroom, I was naked first, but sat on the edge of the bathtub watching her undress. My cock grew stiffer by the second and was pointing skyward by the time she was also naked. She stepped into the shower but left the door open as she turned on the water. I watched as she let the water cascade over her body, admiring her curves as she ran her fingers through her wet hair.
“Don’t be tugging on that too hard just yet,” she said looking at my erect cock. I hadn’t realised, but I was gently stroking myself as I watched her.
I stepped into the shower behind her and she turned to face me. We hadn’t even kissed properly yet. As she stepped forward my cock poked her in the stomach. She laughed and pressed her body against mine, wrapping her arms around my neck, pulling me down to her. Our lips met, and we kissed long and deep. Our tongues explored each other’s mouths as my hands roamed across her back and then down to her ass, squeezing her cheeks and pulling her into me. M cock twitched against her stomach and she pulled away, giggling.
“He’s keen.”
“Can you blame him?”
I reached for the soap, lathered my hands and began washing her body, taking my time to explore every inch of her for the first time. She held my cock, stroking it back and forth gently, as I soaped up and massaged her tits. Her nipples grew into hard pebbles under my palms and I leaned down to suck first one and then the other.
I spent the next several minutes sucking and tugging on her nipples as she ran her fingers through my hair, cooing and moaning softly. Then I let one hand travel down her stomach and between her thighs. One finger slid easily into her. She was already very wet. I massaged her G-spot with my fingertip while the heel of my thumb rubbed rhythmically against her clit as I continued to suck on one of her nipples. When she began breathing harder and moaning louder I knew she was getting close. I dropped to my knees and ran my tongue over her clit and between her lips, feeling her body shudder in delight at my touch.
