"Look, it's not that I don't want to, but..."
I was sat on my bed, a towel round my waist, having just gotten out of the shower.
My girlfriend Jen was standing in front of me. Her dark, wet, long hair draped over her right shoulder, her naked body was still glistening from the shower too. She had joined me mid way through washing. The first I was aware she was in there with me was when ax soapy hand reached round my waist and started cleaning my cock with long, wet strokes. Another hand had quickly joined, massaged my balls, to 'make sure the job was done right' in her words.
"Please babe," she pouted, as I snapped back to the bedroom. Her hands were on her hips, giving me full view of her small, perky tits. God she looked good. Her slim figure made them stand out, her nipples staring straight at me.
Now that I thought about it, the shower was probably a build up to her asking this favour.
"It'll just be half an hour. 60 minutes, tops,"
"Isn't it a bit weird though?" I asked. "For you?"
"Why would it be?" Her hands absentmindedly started gliding over her stomach and up to her tits. She knew how to get my attention. The stirring under my towel agreed.
"Your sister. Touching me. While I'm naked!"
She laughed. "You make it sound so seedy. It's a massage. Jess has given me loads. They feel really good. And anyway, you'll have a towel on to hide your modesty." She eyed up the tent that was slowly rising under my current towel "Or at least, I hope," she said with a wink.
I rearranged myself and crossed my legs.
"She just needs to do a few more massages to meet her course requirements. She's almost fully qualified now but is struggling to do these last few bits."
She walked over to me and straddled my lap. Although her tits were on the smaller side, her ass more than made for it. Curves in all the right places, as the cliche would put it. My hands instinctively roamed down there. She rubbed her pussy on the head of cock in response as she sat down.
"I thought you said it was just one massage," I struggled to say, my cock straining to get out from under the towel.
"Well, maybe one or two sessions," she said, as she ground her hips against me. "Definitely no more than three."
She looked into my eyes before kissing me. Her tits pushing against me and her pussy grinding a little harder. I grabbed her ass, pulling her cheeks apart ever so slightly. Even though I couldn't see, I sensed her asshole wink, which made me all the more harder.
"Please," she whispered as she broke off her kiss.
"Ok," I whispered back, squeezing her ass. She moaned in response, eyes closed, smiling to herself. I went in for a kiss but just as our lips touched, she slowly pulled back. Then smiled and got off my lap
"Thanks baby," she said, and walked towards our wardrobe to get dressed. "I'll text her this morning."
A little light headed, I just looked at her opened mouthed. My cock was rock hard, and now leaked pre cum into a spot on my towel. I needed release, especially after the shower tease - she'd stopped playing with my cock after a few minutes and started to wash her hair. My attempts of playing with he soapy tits and ass were meet with a playful smack each time.
"Erm, are we not going to...?" I started, nodding to my crotch.
She looked over her shoulder with a mischievous grin. This time, she smacked her ass to let it jiggle, just the way she knew I liked. Then turned round, before kneeling down in front of me. Again, looking into my eyes, she placed a palm on the towel, feeling my cock underneath.
Without breaking eye contact, she pulled the towel down and gasped as my cock sprung up, almost hitting her in the face. She giggled. And then wrapped her fingers around my engorged member.
Slowly, she started to stroke my shaft. Running her thumb over the head with my pre cum. I leaned back, to let out a moan. Then, before I knew, I felt the warm wetness of her mouth envelop me. I let out a second, louder moan in response. She swirled her tongue around the head of my cock, while she slowly ran her fingernails up and down my cock.
The teasing had done its job and I was already getting ready to burst. I wanted it to last longer, to enjoy Jen's lips and tongue around me. Maybe fuck her on our bed, bent over with her ass in the air. But then she ran her free hand over my balls and gently squeezed and I knew it was too late. As she gently scratched the underside place between my balls and ass, and darted her tongue around my cock head, I was almost there. I was about to cum...
Then she stopped.
"Shit, I've got to get ready for work," she said, looking at the clock. "I'm going to be late." She jumped up and walked to the wardrobe and started pulling out clothes.
I whimpered. My balls ached and my cock was covered in so much pre cum and spit, I was in agony.
"Babe...?" I started, my wet, hard cock pulsing and bobbing up and down.
"I'm so sorry," she said, pulling her bra and panties on (which weren't exactly helping the situation!) "Can you finish yourself off? I can't be late for work. My boss is just itching to fire me."
I sighed. I guess I could have another shower. I nodded.
"Thanks babe. Now get ready, Jess will be over in a bit to start."
I eyed her suspiciously. "You already told her she could do it, didn't you?" I asked.
She just smiled as she pulled on her trousers. I'd been played. But goddam it, I loved the way her ass looked in those trousers. So I couldn't stay too mad.

Later that afternoon, I answered the door to Jess on my doorstep. She had a bag draped over her shoulder, and massage table folded up next to her.
"Thanks so much for helping me out, Dan" she smiled, readjusting her bag. It looked heavy. God knows what was in there. How many bottles of oil and towels did she have?
"No problem, Jess. Happy to help out." I responded. It was a lie and we both knew it. But neither of us acknowledged it. We were both getting something out of it.
Jen had hinted at finishing off what she started tonight, before heading out the door to work for the day. She worked late on a Saturday, so more than likely I'd not see her until when I would be in bed. I said I wouldn't object to being woken up with a blowjob, just to plant the seed of an idea of how she could repay me. I decided not to jerk off after that. The wait would make it all worthwhile. It meant, however, my cock was twitching at the slightest of things since she left.
"Could you give me a hand with the table?" asked Jess, as she squeezed past me. She turned and her ass (in tight yoga pants) brushed against my crotch. Sending a jolt of electricity down through my cock. I shook my head to gather my thoughts.
"Sure" I said, as I picked it up and brought it inside. "Where do you want to do it?"
Jess blushed. "Why that's a little forward. This isn't that type of massage."
It was my turn to blush. Jess had the habit of making me flustered in her presence. Even though they were close sisters, Jess and Jen couldn't have looked more different. While Jen was shorter than me, slim build with small tits and dark hair, Jess was taller than I was, curvier than Jen and had big tits and blonde hair. And while Jen's body was tatto-free, Jess had a sleeve, a pretty cool throat design and a few more dotted all over her. Jen had told me one night after a few drinks that Jess's tattoos also ran down her side, under her tits and onto her ass. Apparently seeing her naked was a sight to see.
Speaking of which, the only similarity between them was they both had nice big asses. Not that I spent that long looking at Jess's. But after having an up close experience of it just now, it seemed like a family trait.
"I'm kidding, Dan. God you're so easy to wind up" laughed Jess. "Would you be comfortable doing it in your bedroom?"
Her choice of words didn't do much to help the blushing, but I nodded. I guess if I was just going to be just wearing a towel, the bedroom was the most relaxing place to be. I wasn't in the habit of walking around the house naked.
"That sounds like a good idea. Do you want me to do anything in particular?"
"Nope. Just get undressed and lie on your front. With a towel, obviously. I'll do the rest."
She put her bag down in front of me and bent over to rummage through it. Her ass was sticking out and staring right at me. Wow. If it was possible, it was better than Jen's. Who knew you could improve on perfection? As Jess continued to go through her bag, she hummed and swayed side to side. Her ass taunted me. I was hypnotised.
Then, she slowly squatted to look more closely in her bag. I couldn't move. I tried to walk away but my eyes were glued to the shapely softness in front of me. And my cock had noticed too. It started to shift in my pants, as if seeking out Jess's ass. Both her ass cheeks were sculpted in her pants, showing off her curves. If this had been Jen, my hands would have already been wondering all over her ass. Squeezing, spanking, stroking...
After a few more seconds, I snapped out of it and made my excuses to go the bedroom.
"Don't forget the table, silly," called Jess, still looking in her bag, ass out for me to see.
I came back, quickly grabbed the massage table and headed to my room. After setting it up and getting undressed, I hesitated taking my boxer shorts off. I was semi hard. And I worried how Jess would react if she saw me in this state. I desperately tried thinking unsexy thoughts. But my mind kept coming back to Jess's ass, poured into her yoga pants and showing off all her curvy glory.
Suddenly there was a knock at the door.
"Are you decent?" she asked through the door.
I looked down. My semi was now full on hard. Fuck.
"Erm, are you sure I need all my clothes off? Can I keep my underwear on?" I shouted back.
"Well, it's up to you. It's fine but I might get oil all over them. I'm still a little clumsy when it comes to how much I use!"
Fuck.
"Ok, just give me a minute then."
I took off my boxers and my cock sprung free. To my embarrassment, a little bit of pre cum flung onto the table. I quickly got my towel and laid down on my front on the table, tucking my cock towards my stomach. The door opened before I had the chance to finish putting my towel over me.
"Oops, sorry," said Jess, walking in the room. She came up to the side and put her bag down. "Don't worry, I didn't see much."
