Experimenting

Mark had been happily married to Jennifer for 4 years now. He was 26, and she 25.

Mark himself was of medium height and weight, perhaps even tending towards skinny; black hair that never seemed to look good with any style, and plain brown eyes.

He had always thought of himself as lucky, and that Jen was too good for him: she looked almost like an angel. She was of medium height, but had barely any waist. Her light brown hair seemed to radiate, and hung well past her shoulders; her blue eyes were soft and gentle, her tits were not huge, but firm, and her ass was as tiny as any he had ever seen. She was softly spoken and kind-hearted, but in bed she was uninhibited and wild. At least, she had been. They got on great, but lately, Mark had noticed that she turned back sex more and more often. And when they did do it, she seemed to not have the same passion she had had over the past few years.

One day, Mark decided to ask her about it.

"Jen... tell me... what's wrong?" he asked one night while the two lay in bed. He had tried to seduce her all evening, but now she sat up reading a book.

"Hmmm? What do you mean?" she asked, lowering the book and turning her gaze to Mark.

"I mean... well, how do I say this... why haven't you been as... horny lately?" he asked, regretting it as he saw the angry look on her face.

After an awkward silence that lasted a few moments, the look was replaced by a thoughtful one, and she gave a soft sigh.

"I mean, remember what it used to be like? When we first got married?" he asked.

"Yes, I remember." she said, a smile spreading on her face. It soon disappeared though. "It's just... well, I feel like... experimenting."

Mark raised one eyebrow. "How do you mean?"

"Well... Kara was telling me a while back, about a little sexual... adventure she'd had not long ago. And, well, I suddenly started realising how boring our sex life has been up until now. Well, not boring... it's been great, I guess, but we haven't tried anything new." Jen said, talking quickly.

"This adventure... what was it?" Mark asked, curious and somewhat aroused by the way Jen was speaking.

"It was... a threesome." she said softly.

"So... you want to have a threesome?" Mark asked, his cock twitching with anticipation. He had always fancied Kara...

"Well, I don't know... but if you want to, I'm willing to try, but I don't want you to think I don't love you or anything..."

"No, no, it's quite alright." Mark answered, maybe a little too eagerly. "I mean, if you felt comfortable." he finished, putting his arm around Jen and kissing her on the cheek.

"OK." Jen said, a twinkle in her eye. "Do you mind if it is another guy, because I have someone in mind..." she began.

"Oh... I was kind of... Uh..." Mark said. He fell silent, thinking for a moment.
