As I was contemplating that, my door burst open with Violet, Liza and Trina entering, frantic. I sat dumbfounded, trying to grasp what was going on an...d how they could be alive.“H ... how are you alive? The beast killed all of you last night. I had to watch in horror as it killed everyone I love.”The three girls rushed over and threw their arms around me. All three uttering murmurs of assurance and comfort. Violet was the first to release me and sit back on the bed.“Silly man, we are all fine.. Previously our attempts at these comforts had been barely adequate and short-lived.I watched her as she worked. She sat cross-legged and bent forward in concentration. Her movements caused her heavy breasts to sway and jiggle in an erotic fashion. I suddenly decided work was through for the day and jumped to the soft sand below. Kimberly brushed a strand of hair from her face and looked up at my approach. She smiled uncertainly at me when she noticed my rising erection.Brittany was working. I clamped my lips shut and was rewarded with an extra hard slap to my ass. ?It’s your choice, slut. My cock is going in one of your holes and since only your ass and mouth are free I suggest you choose wisely.?I opened my mouth reluctantly, tears leaking from the corners of my eyes as the man in front of me slid his cock down my throat. He was more gentle than the first man had been but he still caused me to gag and choke as he fucked my mouth. He and the other man began to get into a sort. " I don't think I want to try to seduce my professor to perform an experiment." Sure, but ... is there anyone else you're sleeping with? I mean, it's none of my business, but you could try it with him."Julia smiled. "To know what Carl is thinking? That would be interesting, that's for sure."Bethany hadn't heard anything about Carl, but she knew the older girl had had a series of boyfriends."Listen, I'll get some. You can try it. You have nothing to lose." How do you know it's safe?" I suppose I.
