Just before midnight, Kathy asks again what the cost is for a blowjob. At this point, I'm tired of hearing it and just want the joke to end. I respond...this time, "Oh, how about $50 bucks?" Tom grins, and says loudly, "Deal!". Kathy pulls (2) $20s and a $10 dollar bill out and slips it into my bra. My wife then giggles and says – "That's sounds like prostitution to me. You're going downtown, missy!" Then she handcuffs my hands behind my back again. We then go outside to the limo. Once inside,. I glanced around, tweaked my nipples, smiled, “You never get tired of these, do you?”He smiled back, pointed to his own tee - ‘My Sister is Hot.’He’s been doing that lately, going through a brother / sister phase when we’re out and about. I need to speak to him one of these days, straighten him out. Maybe when I can no longer pass.I ordered fish tacos and we had a rare, leisurely, weekday lunch. Both of us feeling like we were getting away with something. No booze, just a teasing, goofy. My dick still inside her mouth, she swung her big naked body between my legs as I spread them wide apart to accommodate her. She moved her mouth up and down my cock, making slurping noise as I held her head. Then at length, she took it out and started kissing my scrotum and the area below it. I could hold myself no longer and I spurted out a jet of semen; it fell on her lovely face. She immediately held my dick and took it back inside her mouth and I again spurted, this time inside her mouth. It's positive reinforcement. Calling me Daddy makes me feel strong and dominant. It all helps my mental outlook before the race. Don't worry I wouldn't ask you to do such a thing.' Coach said."'Oh I understand. It makes sense.' I said, 'After all, Daddy's such a big strong man.'"'That's a good boy, keep stroking Daddy's big cock baby.'" I have to admit that I did feel a little uncomfortable, but Coach knew best, didn't he Father?" 'Yes, I will keep stroking Daddy. I will keep stroking until you.
