"I think it should be the girlfriend. By the way, Sammy, there's something I've been meaning to tell you." Oh?" I asked, but Tammy cut her off before ...Shirley had a chance to tell me what it was."The roommate needs to take some responsibility in these matters, besides; both dryers have finished their cycle."Shirley beckoned me by curling her forefinger and I reluctantly followed her to the dryers. Tammy was there, helping to fold our clothes so we didn't have a chance to talk privately.They. She was biting her lower lip and was trashing from side to side. She was affected by me suckling and teasing of her boobs. I then licked the skin of her lovely soft boobs tasting the feast that I had on my table. I loved her salty skin. She was delicious. I stopped teasing her boobs and lifted the short skirt she was wearing. I said that she was a very bad girl and bad girls should be spanked. I saw fear creeping into her eyes and I raised my hand high. Then, I spanked her crotch a few times.. She looks outside then asks me if it was ok where she parked her car, she didn't want to have a ticket, but from where I stood I couldn't see it, I asked her where whole going towards the front of the store, she followed me and stood behind me pointing at the car I pulled back saying yes you are ok there, but by pulling back my elbow rubbed on her boob she didn't jump she just pretended it didn't happen. But her nipple on my bicep confirmed my eye sight as of how hard they were.We walked back. She looked into my eyes and smiled. "Stage two," she said.I felt myself gradually stretch open sideways. Damned if it didn't feel like the cock inside me was getting thicker."This is something newly out of our research labs," she said. "It's an expanding cock. I can widen it from its normally erect two-inch diameter to four inches. And lengthen it correspondingly."I could feel the depth of penetration increase as the cock within me swelled up. Deeper and wider. That cock of hers was a damned.
