Summer smiled, "Because you need to get used to blowing guys honey. It's not enough you can swallow a banana whole. You need to get used to the tasking so when you do get a guy he'll love not only you but what you can do. So back you go."
Kel lightly rubbed her jaw but she went back to work by opening her mouth and swallowing my dick whole.
My eyes fluttered as I felt my dick go back into Kel's warm wet mouth.
I felt her wrap her lips and strengthen as her lips became a vacuum seal on my dick. Then her head started bobbing traveling up and down my shaft again.
Summer started to coach Kel, "If her jaw starts to hurt just simply switch from using your mouth entirely to your hand jerking him off while your mouth stays on his dick. You can also mix the two movements if that helps too."
Kel took that information and started using her hand working the bottom half of my dick massaging the shaft while her mouth and tongue worked the upper half.
She would stop and kiss the head and sides of my dick while using her hand to fully massage my shaft never touching the tip.
Then she'd go back to working the full length with mouth.
All the switching was just bringing me closer and closer to firing.
Normally when a girl gives me a beege I like to think during that time that I have a fair bit of stamina. I'm not a two pump chump.
On average most of the girl's that have given me a blowjob most haven't been able to fully take me Thanks in partly to my fascination with small girls. And for the most those that can't take me fully I've been able to last what feels like forever until I'm actually fucking them. Then I'm your average joe lasting 'x' amount of time.
Then the few girls like Jessica, Summer and now Kelly who can actually fully take me I feel like the dynamic has changed and my stamina drastically declines.
Especially when Summer took my nuts in her mouth my stamina just plummeted.
Now with Kelly's current technique my stamina was just taken away piece by piece as she introduced a new technique or in the combined many techniques into one.
When Kelly added massaging my balls while her other hand was massaging my bottom shaft and her mouth was bobbing the upper. I was ready to fire.
My back arched, I started grunting, my eyes rolled again into the back of my head. My toes curled. My balls felt like they were bouncing in Kelly's hand as they unloaded rope after rope.
Kel's hand disappeared as she simultaneously deep throated me letting my dick pump my load down her throat.
Kelly opened her mouth while still letting her lips wrap firmly would my base letting my dick bounce and twitch as each release of cum passed through my dick went down her throat without touching her mouth.
Each pass made me grunt louder and louder until my voice felt completely horse.
Finally the last remnants of my orgasm passed and my load firing became less and less until it was gone.
Kel felt the last of it. Still keeping her lips wrapped would my dick she used her lip muscles to suction and lifted her head causing me to twitch now that my dick was completely sensitive.
Once her lips freed enough of my dick she wrapped her hand and pressed her thumb against the bottom side of my shaft and continued to milk my dick as her head lifted.
When her lips hit my tip she kept her head in place and used her hand to continue milking my dick releasing the last remnants of my seed out and onto her tongue.
This caused me to twitch and groan while trying to get away from the new cum vacuum otherwise known as Kelly.
Once she was satisfied that she had gotten everything out of my dick did she release my precious sensitive appendage to the world letting my boy lightly slap down against my stomach as he began his shrinking process.
I looked up at Kelly as she showed me the last remnants of my protein rich spunk laying on her tongue. Once she knew I was looking at her she closed her mouth made a show of swallowing and opening her mouth that she has performed a magic trick special only for me.
Then she smiled and looked up at Summer.
Summer lightly clapped, "Bravo! How was it?"
Kel smiled lightly blushing and said, "Exhilarating."
I laid my head back panting as the girl's talked.
My sister had just completed Summer's lesson on blowjob and now had been converted into a specialized protein swallower.
Now with that lesson completed. I wondered what Summer's next lesson planned for Kelly was and if she will pass that as well.
My only question is....will I survive these two?
