His rough yet gently tongue worked its way into my puffed-up hole. I was so exited, that my vagina had swollen to twice its size. My moist lips gliste... with lubrication. In one quick move he went up to my butt-hole. I instantly stood up straight. “I told you not to move!” he put his hand on my back and pushed me back down, slamming my head on the desk. “When I say don’t move, you don’t fucken move --- do you understand?!” He pulled me by my hair and pinched my nipples hard. “Ahhh mmmm” was all. If we weren’t watching the noise alone would be a turn on as Jan screams with every orgasm and his balls slap into her. We can see Jon tensing as he nears orgasm. He pulls out of Jan and motions for her stroke his cock to orgasm.We watch fascinated and rapt as Jan uses two hands along his full length. She is in her element now, his huge cock that she has craved for a month in her hands. She expertly teases the tip of his cock. “Cum for us baby. You have had a rock hard erection for an hour.. But you could've left a note or something. If I disappeared on you like that you'd be flipping out too! And it's Mom's birthday for God's sake!"She shrugged, feigning indifference. "It's no big deal. I just realized I hadn't been out on a date since ... forever!" Who is that guy out there?" I repeated."He's just someone I met," she said evasively."Where'd you meet him?" Downtown." Now there was no eye contact."Where downtown?" None of your business! He's a nice guy!" Where downtown?" I. I had to see the thing charging bullet-like piss against this wall. I tried to be subtle but surely failed as I turned to look down at his cock. It was magnificent. It was like a long, thick branch standing out of a tree. It was as brown as the rest of his body – not having those trunks on definitely did him favours. My heart started racing. I hadn’t seen a cock so big, particularly one pissing right next to me. At that point I realised I was staring so I jerked my head back, staring straight.
