Author's Note: If you haven't read the first three parts, you probably should so you can understand what's going on between all the parties involved: two couples - Dave & Bev, and John & Janet. If shared wives or swinger sex is something you don't enjoy or approve of, you probably should move on and not waste your time with this story series.
*****
Only a couple days had passed before John texted Dave and Bev in a group text. "Saturday evening looks good for setting something up if that works for you all."
Dave waited for Bev to reply, letting her take the lead. She was usually the one controlling their social calendar anyway and would know if she'd already committed them to anything. He didn't have to wait long as Bev replied relatively quickly. "Saturday is fine. Do you want me to send you both an invitation?"
"That would be great," replied John. A few seconds later his phone buzzed with a different group text message and he saw that it was from Bev to both he and his wife, Janet.
"Dinner Saturday night? Homemade pot roast, some desert and then maybe some hot tub time?"
John let Janet reply and it didn't take long. "That sounds great! Want me to bring the desert?"
Bev laughed out loud alone in her home at the thought of Janet bringing desert. Little did Janet know, if Bev and Dave got their way, Janet would be the desert. "Sure, if you'd like," replied Bev to the group text.
"See you about seven?" came the text back from Janet.
"Seven is perfect," replied Bev. "See you then!"
In the group text between John, Dave and Bev, Bev sent, "Make sure she's not had anything to drink before coming over. We don't want her too drunk to know what's going on."
"Understood," replied John back. Part of him was angry that he was being blackmailed into setting his wife up for seduction. Part of him knew it was the only way to keep Bev and Dave from revealing his own blackmail scheme and potentially ruining his life. Strangely though... and this seemed to be the biggest part of him at the moment... part of him was excited at the thought of Dave and Bev seducing his wife. When John envisioned Janet on top of Bev in a sixty-nine while Dave slid his cock into Janet from behind... it never failed to make John's cock pop right up. In the back of his mind where he didn't have to acknowledge it, or could at least more easily deny it, he wondered what was wrong with him.
The next few days passed pretty quickly even though they seemed like torture for John. He was torn between the shame of having blackmailed Bev, the delight at having sexually enjoyed Bev twice now, the guilt he felt for helping to set his wife Janet up to be seduced and how excited he got at the thought of his neighbors using his wife sexually.
When Saturday finally rolled around, John and Janet spent most of the day quite normally. They slept in, enjoyed a leisurely brunch, did chores and relaxed. Janet spent part of her afternoon making banana pudding which she intended to take over to Dave & Bev's for desert. Before going over to their neighbors, John and Janet went through their usual "going out" routine of trimming, shaving and showering. While Janet had no idea what was in store for her at the neighbors', John had spent bits and pieces of the day teasing his wife and hinting at how much he wanted some play time when they got home after dinner. He had been doing the same thing as much as he could for the past several days, constantly trying to build up Janet's levels of desires but doing it so the timing never let them do anything about it. As a result, Janet was feeling pretty horny through the day on Saturday and John had to come up with excuses several times to put her off.
They didn't dress REAL nice for dinner at their neighbors' but they dressed better than normal for around the house or running errands. John had put on a nicely pressed pair of slacks and a button down dress shirt. Janet had put on one of her favorite summer dresses that stopped about mid-thigh and was snug enough to easily show off her sexy curves. It was also snug enough that John could tell she had no underwear on beneath it and she had on her sheerest bra; it gave enough support but didn't really stop her full jugs from jiggling when she walked.
When they were dressed and ready to go Janet grabbed the desert she'd prepared and they headed next door. John felt like he had butterflies in his stomach and Janet had realized there seemed to be something wrong with him, but he insisted he was fine and looking forward to the evening. Janet dismissed her worries, crediting the fact that they'd had so many dinners with Dave and Bev before that this wasn't a particularly exciting idea for him.
Knowing they were expected and entering through the kitchen door like they always had, John and Bev knocked but didn't wait for a reply before going into Dave and Bev's house. Waiting wouldn't have mattered. When John pushed open the door, holding it for Janet as she carried in the desert dish, Dave was standing just a couple feet away and moving to respond to the knock. Bev was at the counter just getting everything out of the crock pot and onto the serving platter.
Acting like there was no hidden agenda or anything amiss, Dave greeted his neighbors like he always had previously anytime they came over or they were together at a community event. He extended his hand to John, a big smile on his face, clapping him on the shoulder with the other hand. "Hey, guys! It's great to see you! Come on in!" Still holding John's hand, Dave leaned over to give Janet a peck on the cheek as she was going by, getting an air peck in return. Janet barely looked at Dave but was smiling big at Bev who was smiling back.
"Hey, girl!" said Bev by way of greeting. "Perfect timing. Dinner will be on the table in just a couple minutes." Then, eyeing the baking dish that Janet was carrying, Bev asked, "What's for desert?"
