Jane took at deep breath, looked directly into my eyes. "Bastard," she almost spat at me. She pulled at her bound wrists and moved around her sister until she was kneeling between her outstretched legs. "Please don't make us do this?" I had moved over to the bench and sat down beside the father who still had his eyes closed and was trying his best to ignore what was happening in front of his. I'd change that in a second. Christi was curled up beside Dave's legs, but also beside mine. I felt her touch my leg with her bound hands. I looked down at her and she was looking up with her pretty face. She whispered to me, "Please don't make them do this. They're too young. It's not necessary." I just shook my head, and resigned, the blonde just turned back and watched, as sobbing, eyes closed, Jane lowered her head between her sister's legs. >From my angle, I could see her tentatively reach out with her tongue and trace up her sister's vaginal lips. Elaine shuddered and Jane raised her head again. "I can't do this." I just showed her the crop and sobbing she bent back to her task. Elaine had her eyes closed as well, probably desperately trying to fantasize that it was her boyfriend licking her between the legs and not her younger sister. I leaned over to my bound and unwilling benchmate and whispered in his ear. "Davie, open your eyes and watch your daughters. They are doing a beautiful thing together." He just shook his head. There were actually tears falling from his eyes. Not sure if they were tears of rage or of grief. "Davie, you realize that I'll make you do it somehow. Maybe you prefer it if your wife joined in with your daughters." I whispered. He opened his eyes and there was just pure hate in them as he glared at me. He tried to say something around Jane's panties, but it came up muffled. Probably some comment on my ancestry. I didn't care as long as he watched. I glanced back at the girls. Jane still had her eyes closed but was doing a passable job of pretending to enjoy eating her sister. Elaine was having a hard time getting the image of her naked sister out of her mind, but she was managing to curb her revulsion enough to make it look like she was enjoying it. And I hadn't even had to hit her. Jane was a pretty powerful persuader when she had to be. Christi couldn't tear her eyes away from the show in front of her. She pulled weakly at her chains but remained reasonably still. I got up from the bench and crouched down beside Christi. I leaned in close to her ear and whispered to her. "You ever given a blow job?" Her face registered some surprise. Up until this point I hadn't asked the women in my power to do anything to or for me. Though they all had offered at some point to try and avoid some unpleasant task. She turned to me, "I thought you'd never ask." "Not me, you wench. Though, maybe later. I'm dying here." Christi, smiled, pleased that I was in some discomfort as well. Her smile disappeared when she realized who the only other man was. The one she had been forced to gag earlier with his own daughter's panties. "Please no. I don't even know the guy. He's their father. It'll kill him if he gets hard while he's forced to watch this." "I know. And besides, you were willing to do me, and you don't know me." "Oh God. Please. His wife is in the store. Don't make me do this." "Are you any good at it?" She swallowed hard. "I've had boyfriends tell me I was." "Can you tell when a guy is about to come?" "Usually." "Alright. I want you to tease him. Give him a blow job, but don't let him come if he even reacts. Got it?" "Please no. I'll crawl to the end of time for you. I'd join the girls. Anything. Please." But she was already rising to her knees, she knew that my decision was made. As she bent her head, I could see the tears begin. Dave's eyes widened as he realized what was about to happen. This gorgeous naked blonde was about to give him head. Her hands secured behind her. On her knees. In the middle of a mall. His daughters having sex in front of him. He shook his head, pulled weakly against the ropes holding him. Mumbled through his gag. She looked at me once more. Pleading in her eyes. I ignored her and moved over to the two naked women on the floor. Trusted her to do what she was told. I heard her whisper to Dave that she was sorry and didn't want to do it either. Elaine was beginning to breathe harder. I ran my finger between Jane's kneeling legs. Jane jumped at the touch but continued to lick her sister. Jane was shivering and dry. I whispered in her ear, "Sixty-nine." She looked at me with a pleading look. Going to be really hard for Elaine to fantasize about her boyfriend with her sister's pussy pressing against her mouth. As Jane struggled to position herself for a sixty-nine, the handcuffs impeding her greatly, I ran my finger through Elaine's pussy. She was damp. Jane managed to get her knees on either side of Elaine's head and lowered herself to Elaine's mouth. Elaine wrinkled her nose and turned her head. Jane looked up at me from the floor. "Please don't make us continue." "Jane ..." "Okay, but please untie me. I can sixty nine better if I can support myself. It's okay to have my hands behind my back if I'm just kneeling there, but this is different. Don't worry, I get the point that you don't want me to use my fingers." Now that made some sense. I toyed with making her struggle with it, but since she had been so cooperative, I reached down and released her wrists. She brought her arms forward and supported herself, hands and knees over her bound sister. Gently she lowered herself until she was pressed against her sisters body. Rubbing the bare skin together, breasts softly touching her sister. She bent her head to her sister's pussy again. Her sister moaned but refused to use her tongue on Jane. Without warning, I brought the crop down on Elaine's outstretched thigh right beside Jane's working head. Elaine screamed as the welt formed. She got the picture quick. As I checked next, Elaine was crying, but using her mouth to lick and pleasure Jane. Jane still didn't seem very wet, but as long as an orgasm happened, I didn't much care. I glanced over to the bench and watched as the father struggled against warring forces. The gorgeous blonde, naked and bound in front of him, forced to suck him. Every man's dream. Her lips and tongue running up and down him. Loyalty to his family. Not wanting to react. His daughters naked and having sex in front of him. Disgust warring with pleasure. I sat on the bench beside the father. Him still trying to bargain, or curse through the panties. Watching Christi bring him to hardness, slowly moving her head up and down, her tongue snaking out to tease him. Despite all his efforts, unable to keep his penis soft. Christi, backing off as he began to enjoy her mouth too much. Biting him on command whenever I noticed his eyes closing or him not paying attention to Jane and Elaine. Tears falling from her eyes as she had to take him back into her mouth to begin the cycle again. After about half hour, Elaine shuddered in orgasm. Pulling against her ropes. I was actually surprised that she had reached orgasm before Jane. Jane looked more like the type to finish quickly to get it over with. After Elaine had orgasmed, Jane lifted her head and looked at me, as though to ask permission to stop licking Elaine. I nodded and Jane sat up to her knees, her vagina pressed to Elaine's face. Elaine continued her tonguing, as Jane flushed. Her hands raised to fondle her own breasts. Pinching the nipple and tracing the small welt where the crop had caught her. She probably began to fantasize that maybe some guy was eating her out. Within minutes Jane cried out softly, and stiffened in her own orgasm. Finally falling forward in exhaustion. Elaine gratefully stopped tonguing her sister. Christi, noticing that the girls had completed their task stopped her blowjob and looked at me expectantly. I motioned that she could stop, leaving Dave hard and uncomfortable and moaning through the panties. Christi curled up to her seated position on the mall tile beside his bound legs, breathing hard. I walked over to Jane and Elaine, and stretched out Jane's arms until she gripped her sister's ankle. I wrapped rope around both limbs and lashed her wrists to Elaine's ankles. Jane made no resistance as I did the same to her bare legs. Lashing her to her sister. Bare skin pressing together as they relaxed from their ordeal. I allowed Dave to close his eyes again, knowing full well that all he could see behind his closed lids was probably Christi's head bobbing up and down on his penis or his daughters locked in a sixty-nine. Either way was torture enough.
