Amazing Blow Job, And Maybe.

Out with my girlfriend recently, we both had a bit too much to drink. Later on feeling horny, I tried to get her to give me a blow job at her house.
Her brother who's gay was in, but I was so turned on I still wanted oral sex.
Laughing, she asked me to wear a scarf she'd been wearing as a wrap, across my eyes. Telling me she needed a pee after only a minute of her sucking my cock in their kitchen, she left me. But then returned quicker than I expected.
Talk about an amazing blow job. Her mouth worked my cock like never before and in a first, she deep throated me.
Using her hands, she pushed my backside up so I was fucking her mouth, and continued to have me thrust into her wonderful face.
Not able to hold off, my cock unloaded and I spurted my cum down her throat. She gulped it down, then made me wait holding the scarf to my eyes.
I waited a minute then took the scarf away, just in time to see my girlfriend walk back into the kitchen.
She said "You're not horny anymore, I guess. Sorry I've just began my monthly".
She'd been in the bathroom the whole time.
Getting myself together, we walked into the lounge to see her brother Alex, smiling like a Cheshire cat.
He said hello, and wiped his lips after doing a prolonged lick of them.
Before I left, already figuring out it was Alex who'd sucked me off, he told me my cock was gorgeous and my cum extra tasty.
It was said quietly and I obviously didn't tell my girlfriend before I left.
I'm still not sure how Alex got my number, but he text me the following day, asking me if I wanted a repeat performance.
We met at a place he knew and for half an hour in my car, my girlfriends younger brother gave me the most intense and amazing blow job. It was even better than the day before and I watched him the whole time.
When he drained my balls, I swear his cock sucking was like a vacuum. Every single drop slid down his throat and I could tell he enjoyed every second of giving me oral pleasure.
We've met up several times since, and each time just seems to get more and more wonderful.
Alex, only a couple of days ago whilst licking my balls prior to sucking me off again, asked me if I'd fuck him. I didn't then, but I can't tell you just how tempted I was and are. But I'm not sure if I'm ready to cross the line. But then, I guess I probably already have.
