My cock was stiffening quickly and she started rubbing her groin against it. Her hands were on my ass too.We broke the kiss as the elevator stopped at...our level, and my now erect cock was pretty evident. Nobody was around and we walked towards the car. I had my hand on her ass and moved it down and under her skirt. I was surprised to find she'd removed her underwear at some point and was able to slide my fingers between her butt cheeks. She placed her hand on my crotch, squeezing my cock. Not a problem I told her. Inwardly I got very excited. I have had a crush on Chris for some time now. Chris was about 6 ft tall 215 lbs and solid muscle. Being a fireman meant he needed to stay in shape and apparently Chris took his job seriously. The other thing I about Chris that excited me was the sizable bulge he always seemed to have in his pants. When Dee was drunk she would tell the girls about Chris’ monster cock and his skill using it to please her. Intrigued at my new possibilities I. Without much experience, I had hope my enthusiasm would make up for my lack of cunt lapping experience. It sure seemed like it did. Using all the tricks I had learned from porno videos, I licked for all I was worth hitting her clit from all directions and varying my speed. Moaning her pleasure, I thought I was going to suffocate as my sister ground her hips onto my face while applying pressure with her hand to the back of my head. I guess she didn’t want me to stop. “Enough” she screamed “I. ‘He must have been hard for a long time,’ I thought.I slowly took his cock in my mouth and sucked it simultaneously, also stroking it. His dick was so long, so I had to stroke with two hands. Meanwhile, I removed the safety pin that held my pallu and let it fall down, showing him my cleavage. His dick pumped a bit inside my mouth after he looked at my cleavage. I touched his balls. They were definitely ready to shoot the sperms. So I continued sucking and rubbing his balls. He held my head.
