She's right you should be proud, act normal
From Create Your Own Story
"Thanks" you say while your try to compose yourself
"Obviously, you have to take care of that before you can study, what you watching?"
You show her your computer, "Just something hot and quick not to much foreplay"
"Well, she's clearly hot, kinda looks like your sister"
"I guess so, didn't realise" she was right, but it was unintentionally, although you have imagined your oldest sister naked, while jerking off, it was only during extremely 'deprived' family holidays, and when she accidentally flashed you.
"It makes sense, she's a good looking girl." You nod in response, "You know, you should rest your arm, so you can use it to study later"
"I agree," you say in a sarcastic tone, "I guess I'll just use my third arm to Finish."
"Very funny, here let me.." she confidently reaches over with arm and grabs the base of your cock, you gasp slightly and freeze as your mind comprehends what is happening.
"What....what are you..." you stutter as she begins to stroke
"Giving your arm a rest duh." she says while giggling and slowly rubbing the full length of your cock "Don't worry I won't tell anyone, and don't pretend that you weren't staring at my tits in the kitchen."
"No... I was just.."
"Oh calm down." she removes her hand from your cock, sits directly opposite you and removes her dress, allowing her massive breasts to just fall free, and hang, "I mean I can hardly blame you." she uses her hands to squeeze her tits together, as your cock begins to twitch with desperation, "So I might as well help you out, right?"
In that moment you regain your senses,
"I suppose if you give me and hand that would be ok."
"I'm not sure a handjob will be enough"
