Tom agrees to Bill's proposal

“Ok ok, wait, maybe we can work something out.” Bill looked at him expectantly. “Maybe she can do the sessions with you, but you have to follow some rules. If you break a single rule then this whole thing is over and you’ll never get to touch Emily ever again.”

“Hmm, ok, but what would the rules be?”

“Emily will be fully clothed, you are not allowed to remove any of her clothes or touch any intimate part of her covered by her clothing. No kissing. She can give you a handjob or a blowjob and that’s it, no fucking!”

“Come on, I’ve already seen her fully naked, at least let her go topless!”

“Ok fine, but you’re still not allowed to touch her breasts!”

Bill grunted. “Fine, I agree to your terms. Do you want your first session now?”

Tom suddenly felt self-conscious again as he realised he had a massive hard-on. “Umm, yeah, ok.”

“Ok, you stand over there,” he said to Tom, pointing to the corner of the room, and sat down on the bed himself and looked at Emily, “and you come sit yourself here and show me a good time.”

Emily stepped over to him and sat herself tentatively in his lap, facing him. Bill began stroking her thighs. She looked over to Tom, to see him already rubbing his dick through his jeans. She looked back to Bill and he leant in for a kiss. She turned her head away and instead he began sloppily kissing her neck. He pulled her shirt off and she let him, though did nothing to help him. Growing frustrated Bill pushed Emily off his lap onto the bed beside him. He pulled his cock back out of his pants.

“Ok bitch, let’s show your husband how you worked my dick the other day!”

Emily bent over and licked all over the head of his cock, noting the different taste of it today, her juices having coated it earlier. She looked up and saw the intense arousal on Tom’s face as he furiously jerked his dick. She felt a flush of arousal go through her at the thought of her long term boyfriend watching her behave so naughtily. ‘Oh my god! He only just saw me about to give up my virginity to Bill!’ she thought. ‘And yet he still wants me to suck Bill off in front of him.”

Emily gave one last lick to Bill’s dick, licking all the way around the rim, before slowly sinking her mouth over the head. She sucked enthusiastically, using her tongue to give Bill extra pleasure. Bill grunted in pleasure, then reached over and grabbed her ass. Emily arched her back and pushed her butt back into his hand, swaying her hips a bit as she did. She continued to vigorously suck on his cock, bobbing up and down, his cock noisily hitting the back of her throat. Bill was now roughly groping and slapping her ass. Emily moaned around his dick. She felt him slide his hand down her ass and push his fingers between her thighs, roughly massaging her pussy. She looked up at Tom and saw that he’s stopped masturbating and was watching with wide eyes. She reached back and pulled his hand back onto her ass. He grunted in annoyance and began groping and slapping her harder.

Emily moaned and shook her ass for him. Tom groaned at her wanton display and started jacking his cock again. Soon he was shooting his load, the sight of his gorgeous teen girlfriend greedily sucking on a fat old man’s cock as he had his way with her ass too much for him. Emily saw Tom cum and redoubled her effort on Bill’s cock. She grabbed his shaft and worked it with her hands as she bobbed her head down harder on his cock. Despite Emily’s best effort however it was another ten minutes before Bill grabbed her head with one hand and pumped up into her mouth as he came. Tom had pulled out his camera and got a close up shot of Emily gulping down Bill's cum. He didn’t notice Bill slip his hand back down to Emily’s pussy and rub her through panties. Emily felt herself humping against his hand, **** for the release she’d been denied earlier. It wasn’t to come however, with Bill removing his hand once he’d finished cumming.

Emily moaned and sat back, licking a stray drip of cum from her lip, her nipples erect and pointing slightly upwards on her pert tits. Bill stood up and buttoned up his pants. “So, I’ll be seeing you tomorrow for my private session?” he asked Emily. She looked to Tom, who nodded his head. “Well, alright then, see you then.” With that Bill walked out the door.

Emily looked over at Tom. “So, what took you so long to get here? All you had to do was drive around the corner and walk in.”

“Sorry, I just wanted to give you a couple of extra minutes to make sure you’d gotten into it when I came in, I wasn’t expecting him to, well you know…”

“Well that should be the last time we have to worry about any of that,” Emily said, lying back onto the bed and breathing a sigh of relief. As much as she had been enjoying the excitement of the past couple of weeks, she was glad to have some firm rules in place, while still being able to play into Tom’s fantasy.

Emily fell into a blissful, stress-free sleep that night. In the morning though she woke up horny, her pussy swollen and her head still containing the wisps of her dreams about Bill and his big dick. He stayed there for the rest of the day, along with his big dick, making her clench her thighs together in arousal throughout the day. She was incredibly horny by the time she got home. She waited impatiently for an hour before Tom got home before texting Bill to say that she was free to come over. He texted back almost instantly to say he was ready. She quickly got changed into some shorts, the ones from the second skimpiest outfit Tom had bought, and a loose t-shirt. She walked into the living room and gave Tom a peck on the lips and a devilish grin, before darting across the road to Bill’s house, after first making sure no one else was watching. Tom was left sitting on the couch with a hard on, hoping that Emily and Bill would be able to stick to the rules.
