“Oh my…” I stammered, and Toni smiled. She walked over to us and knelt down next to Julie.
“Run your thumb gently up the bottom of his cock,” she suggested, and Julie did.
“No,” Toni said quietly, “more like this.” She wrapped her hand around my cock at the base and pushed her thumb gently into the vein before rolling both thumb and fingers up the full length of my cock. So much for not being involved I thought, but of course I didn’t protest.
“Do you mind me showing her?” Toni asked grinning, but I just moaned. We all knew the answer to that question. Then Julie copied Toni’s move.
“Like this?” she asked.
“Yes,” Toni said, “but change the speed and the pressure on each stroke.”
“Uh huh,” Julie grunted, concentrating on the hand job in hand.
“Not too firm,” Toni advised, “we don’t want him to finish too quickly.”
Needless to say I was in heaven. Toni turned out to be a very ‘hands on’ and extremely knowledgeable teacher, and Julie was a very eager student who learned fast. After a minute or two of hand stimulation Toni finally moved it to the next stage.
“Lick it first,” she suggested, “like an ice cream.” And Julie did. Not too long later a bead of pre cum appeared at the end of my cock and Julie looked questioningly at Toni.
“What do I do with that?” she asked, and Toni quickly leant in and licked it off.
“You’ll have to be quick to beat me to it,” she replied, “he tastes great.”
From there it was almost a game for them. Julie did most of the work under Toni’s instructions, licking, nibbling and sucking my cock gently. Toni would join in now and then, usually to show Julie some trick or technique, but sometimes it seemed that she just wanted to have a turn. I swear she was enjoying the situation immensely. When my pre cum appeared it was a competition to see who would lick it off first. This was sibling competitiveness taken to a whole new level. For the first couple of times Julie seemed a bit unsure of the taste, but then she got right into it.
I was moaning constantly in pleasure as the scantily clad sisters bantered happily while the lesson progressed. They eventually started sucking my cock and Julie managed to take about four inches into her mouth before coughing and spluttering, and after a few attempts she looked at Toni.
“Just go with that for the moment,” Toni advised, “deep throat is a whole new lesson.”
“Any time,” I groaned, and the girls giggled appreciatively as they exchanged a look I didn’t quite understand.
“How much of it can you take?” Julie asked.
Toni was accomplished at deep throat, and Julie and I both watched in amazement as her lips met my pubic hair.
“It’s not really all that important,” Toni explained as Julie sucked my cock once more. “The most sensitive bit is the end, so that’s where you really need to be working anyway.”
“Really?” Julie asked.
“Really,” I confirmed, grinning widely. “But look out because I’m not going to last much longer.”
“Now,” Toni said, “we get serious about milking this great big cock.”
Julie’s lips were stretched wide around my cock as she pumped her head up and down rapidly. On Toni’s urging she was sucking hard as well, occasionally slurping noisily as she pulled back too far and the seal was broken.
“That’s it Julie,” Toni cried loudly, ‘fuck him with your face, fuck him hard.” Then Toni reached across and grabbed one of my balls in each of her hands, and then she squeezed them firmly.
I cried in pleasure as the cum boiled up out my balls, and I shot a huge spurt straight into Julie’s mouth. She spluttered and coughed as another squirt, just as strong as the first one, followed. Julie was trying to pull her head away but her sister had quickly released one of my balls and had her hand at the back of Julie’s head, forcing her down. I must have sprayed into that soft warm mouth at least ten times before the pressure even started to reduce and Julie was spluttering and coughing, her tears flowing freely, as my cum flowed out of her mouth and back down the shaft of my cock. I waited for Toni to let her recover, but she kept up the pressure on Julie’s head.
“Lick it up,” Toni demanded after Julie finally settled down.
“It’s salty,” Julie said, warily eyeing the pools of cum on my body.
“I know, isn’t it great?” Toni asked. Then she leant forward and licked up a big glob.
“Mmmmmm,” she moaned with appreciation. I watched Julie closely as she steeled herself and then she too had a lick.
It was sort of like two cats cleaning themselves and each other, but somehow my cock was in the middle. I had just experienced the most powerful orgasm of my life and I was incredibly exhausted, but there was no way my eyes were going to close when the view of the two gorgeous semi-naked sisters licking me clean was right there in front of me. I groaned again in ecstasy.
“Which wall will you do?” Julie asked me about ten minutes later.
“Huh?” I was confused.
“You can’t be completely satisfied because I didn’t swallow it all, so you choose.”
“I am satisfied,” I replied, and I certainly was.
“I didn’t keep the bargain properly,” she insisted, “you have to choose.”
Rather than argue I just pointed at the second wall that faced the street and a grin split her face.
“Thank you Darren,” she said happily, and she kissed me deeply. I wasn’t sure if I should be happy with the unexpected kiss or unhappy because I was pretty sure that the peculiar taste in her mouth was my own semen. I eventually settled for happy and I hugged her to me as the kiss stretched on and on until Toni cleared her throat beside us.
“Can I have a turn?” she asked, and I wondered just how happy one man could possibly be.
PART FOUR
I would swear it took two days for the smile to fade off my face. I heard the phrase ‘You look happy’ so many times in that period that I wondered if it was a permanent change. Once again I changed the screens the next morning and once again they didn’t seem to be quite so bad. It is hard to hate a football team totally when it’s two most attractive poster girls have sucked your dick so well that it damn near turned you inside out.
My mind was turning over the bet again, and I finally decided to give Julie some sympathy, and some credit for a job very well done, when it came to the anal sex. I couldn’t turn down the opportunity to fuck her, and that was something that I was now anticipating so much that it was the source of every erotic dream that I was having. I just couldn’t wait.
“Darren?” Julie said when she got home from work.
“Yes?”
“How do I know you don’t have any… uh…” she stopped short of saying it.
“Diseases? Sexually transmitted ones?” I filled in for her, and she smiled gratefully.
“Yes.”
“I haven’t had unprotected sex since the last time I slept with my wife” I said, and Julie suddenly looked shocked. “Then I got checked after the marriage broke up just in case she had got something and passed it on to me. She hadn’t.” Julie looked a bit happier.
