We decided to try using a Halloween mask, the both of us, and suggested we get mom to buy one too, it would be fun for all of us to hide behind the ma...k, you do things behind a mask, you would not normally do, the truth is we had nothing else, it was the mask or nothing. My mom agreed to it and that Saturday, we all got online with cams on. We casually chatted about things, and talked about different sites, we mentioned a site called literotica.com and Annie mentioned she would check it out, we. They then got up and sat me down in the chair that they had placed at the bottom of the bed and lightly tied my hands to the arms of the chair, they said to stop me touching my cock as they were the only ones allowed to touch it whilst we were together. So I am sat in this chair naked and sporting the biggest hard on that I have ever had the privilege of owning, when Nong took the lead and started to kiss Nina hard on the mouth, tongues and saliva all over their faces. Then Ninas hands started. After a bit of fumbling it sounded like she had removed her wet swimsuit & had started drying herself, when she asked me to dry her back, thrusting her towel at me, I dryed her back looking down to the small of her back to her ample round bum, she looked round asking me if I liked what I saw, I went red, I thought I'm about twenty five years younger than her. She said let me dry your back so like a small boy I turned away from her, she turned to me, drying me, then she pulled my shorts down, I. " Debbie, I have to study." What about me? I have needs too. Here, kiss my breasts. See? I have buttons up here too." Pull your sweater down." Please? Oh, that's nice. Don't forget to keep your finger going. That's a lot better than your square root." Debbie..." Keep sucking my nipples, don't talk. And keep your finger going. Oh, that's good. Uhnh... Oh Johnny, thank you." Now can I study?" Aw, Johnnie, that was just a little one. I want one of those big crashing ones. I want to come the way I.
