I gasped again as a finger deftly felt my anus and he teased the entrance by brushing the hole.At this point I was with my back to him, his own cock p...king me in the back. I reached an arm round behind him and brushed his lips with mine. I shifted my body, yearning for him to pleasure me some more. He moved his head back and spread my arse cheeks apart. The water combined with the shower gel allowed him easy access as his penis slid into me. He was gentle, pushing a little bit at a time. Flush…swoosh. Our thighs were hitting and giving a sound.Then on one backstroke I pulled back completely out of contact. Mom kept her ass lifted up, waiting for me to slide my cock back along her pussy. Instead, I grasped my cock in my hand, pressed its head part way into her slit, and slid it along her length and back, slowly, three or four times. “Ohhhuuhhhahhhhh,” she repeated each time.I paused, ecstatic at her wanton sound, knowing she was lost in the feel of my cock on her pussy. It was. Her bottom presented perfectly, protruding beyond my right thigh, the tights leaving little to the imagination as they drew even tighter as she bent, displaying a full bottom which I could only describe as magnificent. Lucy was naturally quite shy so I wanted to engage her “What’s about to happen to you Lucy, I want to be sure you fully understand?” Lucy turned her head as far as it would go towards me “You’re going to spank my bottom over my tights Sir until you can see it glow red through. Her hips thrust against the bottle as she moaned loudly that she was coming. Both hands were on the bottle, pushing it in and pulling it out like an artificial cock, driving her to a very audible orgasm. She was up on her toes with her legs splayed wide apart as she lay back as far as she could on the chair. The makeshift dildo pushed hard into her sopping wet pussy, her hips thrust upwards in ecstasy as she reached what looked like an earth shattering climax.She wasn't finished showing off.
