Dan was fast asleep as the morning came; he couldn't sleep a wink the night before. His conscious was loaded with regret and guilt, and his stomach was in knots. He woke to the feeling of cold metal on his wrists, and a metallic clicking sound.
As he opened his eyes he saw Steph handcuffing him to the bed post. His left wrist was attached as she straddled his body and looked him in the eyes. She was completely nude and her breasts were hanging in front of her like beautiful bags of fat. Dan absolutely loved big humongous breasts.
"Hi, loverboy," steph said as she smiled with glee. "Ashley left with her friend to go shopping at some mall around two hours away, she won't be back for quite awhile. So we're going to have some fun for awhile. What do you say?" She knows as well as him that he has no say in the matter, but she wants to test her slave and make sure he responds as one should.
Dan shocked, sad, and still emotionally destroyed from last night said the only thing his mind knew to say, "yes master."
His eyes were sad and he lowered them as he looked at her golden hairy bush. His cock was hard but not from horniness; he really had to go to the restroom. As he does every morning he woke up. He said in a pleading voice, "I know we will have sex, but I really need to use the bathroom first. Can I please master?"
"Since you called me master and responded so well, yes, you can go to the bathroom, but you better come right back here," Steph said as she slid off of him, and unhooked his cuff from the bed post. "Hurry back," she said with a devilish smile.
Dan drained his filled bladder, and went back into his bedroom wearing only his boxers; his cock was no longer erect. He walked back to his bed like a sad puppy and laid on the bed; he hooked his cuff back to the post.
"I must say I am very surprised and happy how well behaved your being. Very good slave; I won't forget this because I'm a kind master," Steph smirked as she straddled him again, and cuffed his other wrist to the bedpost.
"I'm new to this whole blackmail sex thing as much as you, so I figured I'm going to see just how fun it is to have a helpless man to fuck," She said as she sat next to him, and slid off his boxers. She grabbed his limp dick, and put it in her mouth sucking on it like it was a spaghetti noodle hanging out of her mouth. It twirled in her mouth till it eventually became erect, and was covered in her saliva.
"Mmmh," Dan let out accidently. Even though he was filled with regret he can't deny that he was horny for Steph, and he was enjoying this. Although, he was morally devastated a man is a man, and any guy would love to fuck his girlfriend's sister; at least, Dan, would as long as she wasn't married.
"I see your liking this, but then again what guy doesn't enjoy getting his cock sucked," Steph said as she slid her pussy down by Dan's face. She spread her legs giving Dan a full view of her slightly hairy crotch. Her finger slowly massaged her clit a couple inches from his face, and she started to give him a slow, sensual handjob. She occasionally licked and sucked his shaft, while massaging his balls.
Dan was getting extremely turned on, and eventually was eager to taste, touch or fuck her pussy. He realized she was making him want her, and it was working very well. "You're making me very horny master, oohh, mmmmh," he moaned with pleasure.
He decided last night if he acted like he wanted her (which he really did want her) she would eventually think he wanted to fuck her even without blackmail, and he this would let her not worry as much about the evidence. Once her guard was down it would be easier for him to gain the upper hand, and hopefully get out of this mess. Wasn't a great plan, but the best he could come up with since last night.
"I know, a good master makes her slave want the sex, and I told you I am a good master," Steph said as she stopped what she was doing and put her face in front of Dan's and then kissed him deeply for about 30 seconds. She pulled away and smiled at him as she straddled his face. She pressed her wet cunt against his face, and smeared it all over his face.
"Oh my God, yes, finally," was running through Dan's mind; he was ready as hell to get some of her pussy. As her pussy touched her face he shoved his tongue inside her like a probe to feel out every inch of her wet hole. After he was done twirling his tongue around her pussy he started to suck and bite at her clit. Dan let out muffled, "mmm's" and "ahh's," as he tasted her sweet juices.
