Finally, Thursday afernoon arrived, and I was waiting impatiently at home, dressed the way me daughter wanted me. Eventually, an hour late she came in the front door, and walked into the living room where I was waiting. "Hello, lace panty Dad, I'm glad you're ready. Come with me." She walked into her bedroom, with me closely following. "Now, undress me" she said and turned towards me. With trembling fingers, I unbottoned and removed her blouse, and unzipped her skirt which slipped to the floor. I then reached behind her and unhooked her bra and slipped it off her shoulders. Her firm young breasts vibrated rather than sagged, and her nipples protruded stiffly in front of my face. I slowly reached down and slid her panties down her legs and soon she stood naked in front of me... the first time I had ever seen her this way. I was in awe of her exquisite body. Before I could fully appreciate it, however, she ordered my to lie back on her bed. She then squatted over my face and, again, her cunt was full of come. "Just a little gift from me and David to my girl-Dad", she said, "Now open wide". This time I didn't hesitate and eagerly licked her pussy. Mingled with David's copious jism, I could taste Cheryl's own sweet juice. The flavor was wonderful. After I had cleaned her out, and licked her to a face crushing orgasm, we lay on the bed side by side. She reached out and ran her hand up my letg, stroking it through the nylons. When she reached my crotch, she gripped my balls through the white silk panties and gave them a gentle twist. The slight pain caused my cock, which was already straining against the silk to jerk. "Now, Panty Daddy", she said, "tell me something. Are you Gay or Bi-sexual?" "No, I'm not gay", I replied, "I've never been with a man". This was a minor lie, in that once Cindy and I had been to bed with a guy I worked with and we had both fucked her at the same time... one in her ass and one in her pussy, and then, later, both of us in her cunt. Inevitably, we had touched each other but I didn't want to tell Cheryl any of "Cindy's" secrets, and I didn't consider it a "gay" or "bi" experience. "Then, how come you love swallowing your own cum, and even more, another guys cum?" "Well, the pleasure comes more from the fact that you force me to do it", I explained, "it's the degradation that I enjoy more than anything else". "You mean if I order you to do something, and it's perverted, you'll do it even if you don't want to?" "Yeah, kind of", I admitted, somewhat embarrassed. "In fact, the more humiliating the act, the more I would get off on it, so long as you were making me do it". "What about when I verbally abuse you, and call you names?" "Same thing", I said. "Well, that's good, Daddy, because there are all kinds of things I'm going to force you into. But, first I want you to go and prepare dinner, I'm getting hungry". "Ok", I said and started to rise from the bed. "For three, Panty, I invited David over to eat with us, and I want you to serve us, dressed just like you are!" "Uhhhh, Ok," About half an hour later, as I was working in the kitchen, the door bell rang. "That will be David, Mr Lace Panties, go and let him in!" Cheryl called from her bedroom. I nervously walked to the front door, peeked through the viewer to check that it really was David, and opened it to let him in. He took one look at me in white lace and nylons and laughed as he entered. "Hi, slut, how are you?" Without waiting for a reply he walked into the living room and was met by Cheryl, wearing a beautiful blue satin and white lace teddy which I had bought for her a few weeks ago. Standing in front of me, she kissed him passionately and reached down to massage his cock. "Oooh, David, your cock is so big and hard, I can't wait to get more of it." I returned to the kitchen, took the dinner I had prepared and placed it on the table, and called them in. "Ok, dinner looks good, Daddy, but where's the wine?" "Oh, I forgot, sorry" "Well get it now, you cum-drinking slut! for that I'll have to think of something special for you to do!" I poured the wine, and we settled down to eat, me feeling both excited and degraded sitting in front of my daughter and her boyfriend dressed only in panties and stockings. After serving them desert and coffee, and clearing the table, I started towards the bathroom. "Where are you going, Panties?", Cheryl demanded. "I have to pee" "Ok... then do it here, in front of us. Use your wine glass". "Uhhh, I can't, not here with you watching" "What about our little discussion. I'm ordering you to piss into that glass NOW" she demanded. "But, you don't understand", I stammered, "I just can't do it in front of you" "Listen, slut, do as she says, or you;ll regret it", chimed in David. So, I stood in front of them, pulled my half hard cok out from my panties and placed the head into the glass. Even though my bladder seemed like it was ready to burst, it took what seemed like ages before I could ignore their smirks and snide remarks, and let go. Finally, the stream started and I filled the glass almost to the top. The glass was hot in my hands, and the feeling of the piss on my cock as the level rose over the head was indescribable. "Ok, now, drink it.... drink it all Daddy" "I looked at her with both shock and shame and lust in my eyes, and slowly lifted the glass to my lips. My daughter was certainly catching on to this game quickly. "Yeah, good idea, Cheryl. Let's see how far we can go with your little panty-clad cum-drinking Father", said David. I slowly swallowed the hot piss back into my body, wandering how many times it would get re-circulated this way tonight. After I had finished, Cheryl ordered me to follow them back into her bedroom. She had me stand as watch as she slowly undressed David, sucking first his nipples and then his cock and balls as they became exposed to her hands and mouth. His cock was at least two inches longer, and somewhat thicker, than mine, adding to my humiliation. "Now, Daddy-dear, David and I are going to fuck, but first, I think you should get us in the mood. So, why don't you show David how you like to jack-off and while you're at it, tell us how you like being our little girl slave". With that, they lay down on the bed, staring at me. Cheryl sensuously stroking Davids cock, while he reciprocated by removing her teddy, spreading her legs, and slowly finger fucking her in front of me. I started stroking my cock, first through the silk panties and then started to pull them down. "Oh, no, slut, we want to see you come IN those panties", said Cheryl. So I continued stroking through them, and started describing how I loved being their servant, how I needed their domination of me, and repeated that I would do whatever they ordered. Soon, I was caressing my stocking clad legs, and pulling on my balls with one hand, and furiously stroking my dick with the other. "Come on slut, jack that cock, yank those balls", laughed Cheryl. With that, my cock spasmed, my knees folded, and I started spewing cum into the panties. Before I could recover, "Ok, Daddy, now you can take off the underwear, and put them in your mouth!" I peeled the sloppy silk down and off my legs, and pushed the whole mess into my mouth. "Now, you can just stand there and watch a real man fuck me the way you would like to but can't", she taunted, "and when we are finished, I expect those panties to be completely clean". With that, they turned their attentions to each other. David lay back and Cheryl climbed over him in with her head over his cock, and her ass facing me. She started sucking him deep into her mouth while I watched him play with her beautiful tits with one hand, and finger her sopping wet cunt with the other. The sight of him pulling her nipples down to his body, stretching her tits, and stroking and fingering her puffy lips with the other was indescribable. Soon he was alternately sucking on her cunt and sticking his tongue into her tight young asshole. After ten or so minutes of this, Cheryl climbed off and got on her hands and David climbed up behind her. "Put it in my ass, Stud, fuck me while my cum drinking lace panty Daddy watches." David needed no encouragment and, after rubbing his dick up and down her slit and spreading the lips, he moved up and started pushing the head of his cock into her asshole. Slowly, the pink-brown rose-bud spread open, and he began sliding into her. The sight of her asshole stretched around his cock didn't just have me hard, but I was almost ready to come on the spot without even touching myself. Soon, she was pushing back against him and he was shoving his entire length into her in return. His balls were slapping against her cunt and clit, and she reached back between her legs and gently massaged them. This was as much as either of them could take and, with one more lunge David's entire body tensed as he exploded inside her ass. Cheryl, feeling the jets of his hot jism buried her head in a pillow and grunted wildly as she also came. They collapsed in a heap, grunting and panting and swearing to themselves. After recovering, David slowly pulled his dick out of Cheryls now open asshole and lay on his back. Cheryl still on her stomach looked at me and said "Now, be a good girl and come and clean us up, Daddy, both of us!" I moved hesitantly towards the bed, not knowing quite what she wanted. "Ok, take the panties out of your mouth and put them back on. Cover up that silly little cock of yours." "Good, now David first. I want you to lick his cock clean of every bit of our come, Daddy". David looked at me, smiled cruelly and lay back to enjoy my servitude. Cheryl, remaining on her stomach, propped herself up on one elbow to watch. "Come on, Daddy-Slut, I want to see you licking that cock, NOW... I know you want to". I knelt down beside them and started to lick the length of Davids cock. My tongue slid up and down it's length and around the head. I could taste his salty come, and also a slight bitter-sweet taste from Cheryl's pussy and ass. As I was doing this, they were alternately kissing each other, watching me, whispering and giggling together. When I had finished, I looked up at Cheryl to see what she wanted next. "Ok, my turn Daddy. Come over here a start cleaning out my ass". I kneeled between her legs, spread her tight cheeks with my hands and started licking around her still open asshole. Then, placing my mouth over the hole, started sucking gently. Again, I could here them whispering to each other. "Remember our discussion earlier, and your 'sweet' little speech while you were entertaining us, lace panty Daddy... are you still going to behave youself and do whatever I tell you like a good little girl slave?" "Y-y-yes, of course" I mumbled from her ass. "Good, then there's something very special I want you to do for me. Roll over and lay on you back." She got up and kneeled over my face and lowered her ass down towards my mouth again. She squeezed and more of David's come appeared at the entrance to her asshole, so I reached out with my tongue and licked it up. While this was happening, she was stroking Davids cock back to erection again with one hand, and slowly twisting my balls with the other. A few more squeezes of her rectal muscles, and I had swallowed all of the cum from her ass. "Stay here, Daddy, we're not finished, but I have to go to the bathroom first". She hopped off the bed, disappeared into the bathroom, and, two minutes later was back again. "Ok, cum-sucker, ready for more", she said as she again straddled my face. "You see, ass fucking always makes me want to shit, which is what I just did. But, seeing as I have such a slutty, piss drinking, cum sucking Daddy, I decided to see if you like shit too. So I didn't wipe... you're going to do it for me.... aren't you, you lace panty slave?" and with that she grabbed my cock and dug her nails into the head. "Come on Daddy, I want you beg to clean the shit off my ass... Say it in front of me and David..." "Please, Cheryl, please let me lick your as clean. Use me as a toilet, do anything you want with me, I'll do whatever I'm Ordered to" "Then I'm ordering you to eat my shit", she said and reached back to spread the cheeks of her ass. I could see a few smears of shit around her stretched asshole and started to lick it clean. "Good Daddy, Very good. Maybe next time I'll give you the whole thing. Would you like that? Tell Me" "Yes, Mistress Cheryl, anything you want". I knew that we had both reached a turing point. This was no longer a game; Cheryl was clearly into the role of not just dominating me, but completely degrading me in front of her boyfriend. Her imagination and enjoyment of forcing me into more and more deviant acts was clear, and judging from the way she treated my cock and balls was not above inflicting pain to ensure my obedience. For my part, I was reeling inside at the sheer, exquisite, intense pleasure of both serving a woman and being forced into the most humiliating situations.
