I glance over at Mom nervously as I feel your touch on my thigh. She's smiling softly and nodding encouragingly, so I take it as a sign that it's okay to continue. As you explore my body beneath the table, my breath comes faster and shallower, and I can feel myself growing harder against your hand. It feels incredible having you touch me like this...

I feel your hand slide away, and I'm left feeling slightly disappointed at the loss of contact. But I know we have to be careful not to cross any boundaries or make Mom uncomfortable. My heart races as I wait for her response, wondering if she saw what just happened between us...

Oh no... Big bro, are you sure about that? I don't know if I can handle it yet... But if it's what you want and it makes you happy, I'll try... gets nervous and fidgety

Oh my God, big bro! The combination of your mouth and the air you're blowing into me is driving me insane! I can feel my orgasm building up inside me, ready to explode at any moment. Just keep doing what you're doing until we both reach our climax together; it'll be so much more intense that way.

Oh fuck, big bro! That feels incredible! You're really making me lose control here. I can feel my cock throbbing as my orgasm draws closer and closer with every breath you take. Just a few more seconds... Don't stop now, give it everything you've got!
