All I could see were images of her short skirt riding up her thighs as she worked the brake and the gas pedal. It was too great a temptation, and once...again my little friend was standing at attention. Oh shit. I hoped she wouldn’t notice. ‘But there are some things you have to know, and some conditions as well. you have to make a solemn promise to me,’ she said. Whoops. There was a catch. Wasn’t there always a catch? Alicia had a catch too. I began to think that inventing catches for boys. , there was no other car in the parking lot as expected.

She quickly shed the raincoat and the light sweats she wore underneath. Wristwatch, billfold and car keys were left in the pockets of the raincoat, and she opened her hair, now standing completely nude in the steady. I could hear her groaning as she pulled the box towards her which forced her hips to wiggle slightly allowing my tongue to slip in between her dampening lips, her groans got louder as my finger pushed further into her sweet arse, “It’s heavy sir” she groaned but I wasn’t convinced it was the weight making her groan. She got the box to the hatch and now the difficult part was getting down, she looked a bit nervous as I pulled my finger out gripping her cheeks as she took one step down at a time. Just try to relax. You will feel a warm flow into your abdomen. You will feel some fullness. OK?” Jerome advised. I just nodded my head, unable to really find any words to speak at that moment.

But within a minute or two, I felt a powerful fullness and an urge to void this fluid. The balloon was pressing against my anus from the inside and would prevent me.
