Just as you feel the need to take advantage of the effects you're experiencing, you hear the front door open and then close. That could only mean your wife was finally home from work for the day. You clean up after yourself in the bathroom and quickly go out into the hall to greet her. A smirk on your face, you wander over to her and gently begin to caress her breast. She raises an eyebrow at you in an intrigued manner.
"Hello dear," you say in a lustful tone of voice as you kiss her.
She replies back very playfully, "You're rather frisky suddenly."
You can only nod as you nuzzle her neck with your face. You can't help but feel giddy. Neither can another part of you, feeling the bulge in your pants grow. However, something about it feels different. It actually feels stiffer than normal and practically feels spring activated. You're not sure what to think about this but dismiss it as the effects of the tattoo making you more excited than normal and continue to lavish your wife with attention.
She enjoys every minute of it, returning your caressed by groping your very erect package. She lets out a surprised gasp. "It's so big..."
Your smile grows into an excited grin as you suggest, "Let's go to the bedroom."
Her answer is by following behind you as you both rush upstairs and strip out of your clothes while making out on the way there. You eventually find your way into your room, practically tossing your wife onto the bed. She lets another surprised squeak and then laughs, enjoying your dominance.
Crawling onto the bed, you slither on top of your wife all the while grinning like a sly fox, neither of you noticing that your body hair is receding away. Once on top of her, you lean in and kiss her while you slide off the last article of clothing you have own, your briefs. With everything out of the way, you prepare to mount your wife, using your very erect member to tickle the lips of her vagina. She lets some excited moans, her eyes begging you to get to work. Naturally you can't resist the temptation to finish embarking on this ride...
