Unpleasant earnings

"john texted me saying he was just waking up and is coming soon... You know how stupid he is jane he can't even figure out how to set an alarm"

I can't hear abbie roll her eyes but I know she is. "Oh.... Oh ok well good... I'm so glad he came out.... Oh boy did kara fall asleep too??"

"Oh she is half in half out.... But seriously I don't know why you are so nice to him jane he is weird...... but to each there own I suppose" abbie actually sounds nicer than usual.

I keep trying to listen but I start gagging so hard it's all I can hear. Here dick is bulging my throat out for sure. Lucky for me the pool has music playing and other people around so I'm not heard. I hear a very low whisper "give me atleast 30 reps boy and Ill help you with jane myself"

30... Can I?... The constant gagging is starting to slowly subside as I calm myself... I put my elbows down and push upward... My throat feels like its being resized... Stretched past its limit... As I come down with snot coming out my nose.

"Not far enough... Still 30 to go" she says in a stern tone

Why... Just why.... I push again with all my strength... I feel her mushroom cap hit the deepest part of my body and bottom out... I am beyond gagging now and have a constant shutter that must make me feel like a vibrating fleshlight

"One" she says in a whisper

I start to hear abbie and jane faintly again... "Yes jane it is important... I want my sister to have the full college experience and you can't do that acting like a nun"... 2...

"I know abbie and I do get... Like... Horny but... It... I'm self conscious ok.. you wouldn't understand at all"... 3...

"I do jane I just think you need to step out of your comfort zone were on vacation for god sakes what happens here stays here"... I hope so...

"Like I know you are a virgin but what's one thing you've always wanted to try sexually?"... 4..5......6..

I hear an angry growl "half rep back to 5 no more warnings" kara says in a very angry whisper

I'm trying please.. I'm trying... I feel her flex her dick and a torrent of precum streams into me warming my stomach like a shot of whiskey.

"Well.... I've always wondered what it was like to.. like... Lick a boys... You know!" I hear her play slap abbie.. 7..8..9..10..

"Ohhh baby sis a blowjob?... that is easy".... I feel thick precum ooze from my nose oh so slowly.

"Look jane how about I get you a boy from my school to drive down and you can learn all you want"... I hear jane squeak

"That seems.. I don't know..."... 11.. 12..

I hear a whisper "ah damn you better keep going I'm gonna save your ass."

Kara clears her throat "Hey jane how about that John I keep hearing you talk about?"... I hear abbie scoff but jane speaks up

"he really is so nice and sweet... And Just between us I think I might have made him get a .... You know... Boner (she says in a whisper)... The other day in the camper"

"Ug what a nerd and a perv" abbie says with distain

.. 13.. 14.. 15... Kara speaks up again "Aw it sounds like he has a crush have a heart abbie"... 16.. 17.. 18...

"I could never ask him to help me practice something like that tho... it's so embarrassing I could die... Besides who would want me near their thing with all this metal in my mouth"

I cough really hard as kara's dark sack lays sweaty on my chin... 19... 20.. 21... Kara giggles a little "How about this sweetie I'll talk to him as your friend... Ahhh... Got a cramp... I'll talk to him and let him know you are interested and feel out his response ok?."

As she began that sentence I felt her balls leave my chin... They moved up on there own to begin something they haven't done in a month... The first jet of cum feels like a punch to my stomach.. jizz instantly snakes through my sinuses and out my nose in a flood... It's slightly yellow and so thick it's like chowder...it tastes so bitter I think of abbie in the shower briefly... 22..23...24... On each descent I get another torrent of cum..after rep 23 the streams become pearl white .. I haven't had a good breath since rep 19 and start feeling dizzy.

"Gah fine I'll help too jane but I'm telling you, you could do better" abbie relents.... Jane just giggles

"Really??...I can't believe.. ah I'm so nervous girls you'll have to give me advice if this is for real"

"I know a trick...ah.. or two jane don't you worry" kara says confidently with a slight quiver in her voice... 25.. it starts to slow and I feel so full... 26.. 27... I can barley lift my head but **** myself... No half reps.... 28.. 29... 30... My abs burn... My throat burns... The hot cum in my nose feels like magma... It's so hot under the chair I feel like all of the cum is cooking into my skin... Her dick throbs back and forth even after it stops cumming making me shutter as well.. the cum in my nose settles and blocks my air.

As her dick softens in my throat everything starts to go dark...
