“Oh my god,”, my step sister exclaimed as she walked in on me jerking off with her bra clenched in my hand. “Not again! I thought mom and dad were paying for therapy for this kind of stuff!”
My step sister has always been hot to me, especially her large breasts. The size most porn stars have, except hers were completely natural. Natural yet firm, I’d been caught spying before as well as using some of her personal items for my own pleasure. It turns out that maybe my step sister wasn’t too pleased with that and told our parents and I’ve been in therapy for a while now dealing with the so called “issue”. In fact it was helping until today, when, I was feeling a particular kind of way.
“I’m telling mom!”
“No, wait please don’t!”, I begged.
“Well, what am I supposed to do? Your my little brother and your jerking off into my bra!”, she retorted.
“I can explain, see I wa-”
“I don’t think that’s necessary, I can see pretty clearly what’s happening! Mom!”
“No please, be quiet!”, I half whispered and half yelled.
