Well, you figured you might as well take a shower and give the old log a tug or two. It was your favorite time of day and the weight of being Steve did feel as heavy in those moments. A professional would probably say you were depressed and the release of dopamine's that coming entailed, had gotten you addicted. But in the end, how much you told yourself you were Steve now and David insisted he was 16 and you were 40, on the inside you were still 16 and such thoughts was outside your scope.
So there you were, in the shower, masturbating. Your thick member being stroked up and down with expertise. You had started to find your weak spots and that made masturbating even better. You looked down at the majestic meat between your legs. You rubbed your hairy body with your other hand while moaning. You really wanted to know how having sex felt like. How it would feel to put your large member into the wet warm hole of a woman. Having her moan in pleasure as you pumped her full of your hot jizz. But that was probably never going to happen. That made you mad at your 'son' who was the one that would get to experience that, the one that already had experienced it with this body. That was a new aspect of the swap that made you feel weird. It was still foreign to you that this was your body. But as you got more comfortable with this body, you got less comfortable at the thought that your 'son' had stroked this cock, just like you were now. That your 'son' knew every inch of your body. That you knew everything about your 'son' and his body. It seemed you couldn't win. But you didn't have more time to ponder it. You felt you were close to release.
But as you were almost about to erupt, your 'wife' came into the bathroom. You had forgotten to lock the door. There stood your 'wife', nude, ready to take a shower. Her huge tits hanging down over her fat stomach. Her blue eyes staring at you with horror as she realized she wasn't alone on in the bathroom. She glanced downwards and saw you standing with your throbbing cock in hand. Just as she was about to say "I'm sorry" you couldn't hold it in anymore. You were cumming. You were cumming in front of the woman that used to be your mother. "Oh god" your mother exclaimed and ran out the bathroom. Giving you a great shot of her massive ass.
"Fuck" you said, as you kept oozing out sperm. The worst part wasn't even the fact she had caught you in the act. The worst part wasn't that you came in front of her. The worst part was that as you came, you came thinking that your former mother, now wife, was indeed, a BBW milf. The mental image of her fully nude, her huge tits and her massive ass was enough to make you hard again. This was so wrong. You didn't think to long about it thought, as you rushed out after her.
She was just outside, on the bed. Still naked, still looking shocked. "I'm sorry, I'm sorry" You kept repeating as you couldn't help staring at her large tits, making you grow even harder. Eventually your 'wife' looked at you and told you to get a towel. Pointing at your crotch. Oh shit, you were standing naked in front of her sporting a boner. You went back in and got a towel. Your 'wife' probably realized she was naked as well at that point, because as you got back out with a towel around your waist, Cathy had hidden herself under the covers of the bed.
"I'm sorry" you said again. "I'm sorry, to" Cathy told you. "I should have knocked. I didn't hear the shower for some reason so I just went straight in." She added. "Besides... What you did is perfectly normal. We all have needs. And there wasn't anything happening in there I haven't seen before" she said, now laughing. "It's just a new experience, running in on your 'husband' and thinking you saw something you shouldn't. This is all totally absurd" She added, still laughing. You started to laugh as well. She was right. It was surreal. By all means, Cathy knew exactly how this body looked naked. She'd slept with it at least 4 times even! But still, how much you two called each other Steve and Cathy and calling your father-turned-son David, that wasn't the people you truly were. This was indeed a reminder of that. But the two of you just kept laughing. It was simply so unreal you seemingly couldn't react any other way. After a while thought, the laughter stopped and the reality was setting back in. You both got really embarrassed and you turned away from Catherine hiding underneath the cover. But for some reason, you couldn't stop thinking about her naked body.
Catherine broke the silence. "Well, I need to shower as well. After that I'm going to go for groceries and pick up a few things from some other shops. Maybe you can come with me and help out? Try and forget what happened here by keeping us busy?"
That didn't sound like to bad of an idea, but you weren't sure. After the first work week you were kind of looking forward to a day off.
