Sam "helps" you shower

"That was hot" I said

"Uuh, I'm glad you enjoyed yourself" lucy said quietly. Sam just lay on top of her with his dick still buried inside her.

"Well it's been fun but I'd better go take a shower" I said "I could do with some company though"

"Wha…huh" Sam mumbled as I grabbed his hand. He was still in a daze as I pulled him off the bed and out of my little sister. I heard her gasp as he popped out of her.

I led Sam out of lucy's room and towards the bathroom. This would be a bad time to get caught I thought. I imagined what would happen if my parents caught me and a boy runnning naked through the house and then finding my sister curled up on her bed with cum still dribbling out of her pussy. It made me a little excited.

Sam was soon getting a hold of his senses and as I reached the bathroom door I felt one of his hands grasp my butt.

"Alright Sam" I said sternly "I think you need to pay for spying on me and my sister" as I said this I brushed his hand off my ass and pressed my ass against him. I felt him begin to get hard again as my ass grinded on him. "Don't expect to end up fucking me like you fucked my sister. You're here with to help me shower nothing more" I felt his now fully erect penis slip in between my ass cheeks. He didn't penatrate me, I just clenched my cheeks and continued grinding on him. He moaned softly as my ass slid over his cock. I had to bit my lip to stop myself moaning as he grasped my breasts and slipped his cock over my pussy. I opened the door and stepped inside. He looked disappointed that I stopped touching him. It was gonna be fun to tease him. To let him get so close but never have me.

I walked over to the shower swinging my hips as much as I could. He followed me inside quickly. We both got in the shower and I turned on the water. The feeling on the water caressing over me felt so refreshing. Of course, I was interupted by Sam grasping me around the waist and began gliding is cock over my ass again. I decided to begin teasing him. I slowly bent over lowering myself as I did to stimulate him as much as possible. I reached down for the shampoo bottle at my feet but I suddenly felt him line up with my asshole.

"Ooooo" I moaned suddenly and jerked up as he began to penatrate my ass with his dick "ahhhh" I felt the tip of his penis slip in. I pressed back with my hand trying to hold off his advance. "aaah…oh…no" I said and I felt the pressure on my ass weaken. His tip was still inside me, and I have to admit it was starting to feel pretty good but he wasn't pressing any further. I was still bent over so I decided to reach down again for the bottle. Wether he confused this for a signal to keep going or was just feeling daring, I don't know. I had just grabbed the bottle as I felt him grasp my hips tighter and thrust his hips forward.

"AAAAAHH" I cried as he **** himself halfway inside my ass with no lube. He paused for a split second before thrusting forward again. "AAAAUUGH…Oh…wai…AAAUUUUAGH" with one final push I felt his crotch collide with my ass cheeks.

He had gone in dry and skewered my ass. It felt like it was on fire. I was panting heavily and trying to focus on anything but the feeling in my ass. His cock felt like it was 12" long. I could have sworn that it was pretty close to tickling the back of my throat.

Before I could recover enough to say a word he began to withdraw from my ass. My rear felt very sensitive and I couldn't help but cry out as waves of painful pleasure washed over me. Once he had almost pulled out he paused and prepared to thrust forward again. I knew this was one chance to stop him. I didn't particularly like the sound of being ass **** by my boy neighbour.

I pulled my hips forward and steadied my self on the glass cubicle. The water was still pouring down and I almost slipped. Images of me slipping flashed through my mind. Both of us tumbling backwards and me screaming as his cock fills my ass, when I landed on it.

Lucky I kept my balance and even managed to knock him over slightly. I winced as his cock slipped out of my ass, as he fell back against the wall. I turned back towards him as he got on his feet.

"THAT THE HELL?!" I screamed.
