Blue said, "I think Joe's been a very good boy, shall we reward him?"
Green replied, "Yeah, let's give him a treat!"
They got up and went over, and told Joe, "Ok Joe, we are going to give you a reward for being so patient. You will be a good guy and not try any shit, won't you?"
Joe nodded eagerly, and they uncuffed him and told him to strip. He quickly did so, and his cock was iron hard, god, it was so stiff it hurt.
They led him over to the bed, and Green said, "You'll like this reward. Your sister-in-law is going to suck your cock!"
Joe was all for it, he'd had more than a few fantasies about putting the dick to Linda, and he was eagerly looking forward to having her lips wrapped around his prick, nursing out a big load.
Linda, on the other hand, was aghast. She hated blowjobs, she wouldn't even give her husband a suck job.
She pleaded, "No, I don't suck cock, please, no, I don't even blow my husband, he can fuck me but no cock sucking!"
Corinna looked at her sister, what the fuck? Jeez, this was sure turning into one weird rape!
Blue growled, "You are going to suck Joe's cock, and swallow every drop. Our 2 guns say you shall!"
They released her, and told her, "On your knees, baby, gotta be in the classic subservient cocksucker position!"
Just before she did so, Joe drank in Linda's body. He'd seen it once before, at a drunken New Year's Eve party, when she'd cornered him alone in the back bedroom just after Midnight, and had opened her dress, to let him see that she was very naked underneath. She'd grabbed his head, pulled his head towards her.
She had purred, "Happy New Year Joe," just before their lips met, her tongue had slipped out, pushing at his lips, and he'd opened them, letting out a moan as her tongue darted in. He'd reached around her, grabbing her naked ass cheeks, and pulled her in, rubbing the bulge of his trousers against her naked vulva. After several tongue-filled swirls of passion, she had reluctantly pulled away.
