Time-skip to shower

After a grueling workout by Aunt Heather, terrorizing both you legs and abs, your aunt says it'd be best to go shower. The only problem being that there was only one shower room, because this is a girls only gym (of course with the owner's nephew being the exception). You keep your eyes down as you pass all of the showers, realizing how all of them but one is in use right now, you and your aunt will have to share.

You both get undressed and you feel embarrassed, the only guy in the girls shower room. But before you can think too har, a hand grabs you and shoves you into the shower. It's a very nice shower, with very clean tiles, but before you can think more about shower tiles, a large body presses to you. Aunt Heather was now climbing in and you feel the space of the shower shrink, there's nowhere for you to move to get out of Aunt Heather's way, in fact her massive body seems like it'll take up the entire shower on her own! There's no time to panic as two large spheres move around each side of your head.

You're completely trapped by Aunt Heather (for the second time today) and now you're too tired from working out that you can't even try and protest. You don't even hear the shower turn on before you feel hot water flowing down your body. Aunt Heather moans in pleasure as she grabs her soap. She flips you around (which you're surprised she could find you) so that your stomach is pressed to the wall.

"Lemme wash your back," Aunt Heather says

She starts at your shoulders, slowly moving down towards your back, but not leaving out your chest and stomach too. With her strong hands over your smooth skin, you feel more like you're getting a massage than getting soaped down by your hot aunt. You relax so much, that you don't even realize her hand are on your butt cheeks, only jumping back to reality once Aunt Heather gives your butt a tight squeeze. She lets the water clean the soap off of you.

"Here," Aunt Heather says handing you the bottle of soap "Do me next."

You awkwardly get soap onto your hands as Aunt Heather turns around in the small shower, now she had her ass pinning you to the wall. You start washing her aunt's flawless back, with an occasional "mmm" here and there. You start working your way down like she did, but she stops you once you get to her lower back.

"I think you forgot about the other side." She said giggly.

She pulls your hands to her front and makes you fondle her abundant chest. She makes you squeeze her large breasts and isn't satisfied until you touched every square inch of her chest. She then guides your hands down underneath her boobs to her stomach, tracing all of her abs, before letting you get back to her back. You make it down to her waist before you see your next problem, her massive ass.

"Trouble back there?" Heather asks, turning around.

"Umm no, just need some more soap." you quickly lie, trying to not think about massaging your aunt's ass. You get a bit of a breather as you get more soap to your hands.

"Okay good," Heather says relaxed.

You begin soaping up her butt, noticing now how big it is up close, much wider than you, but still very toned. You make contact with her and she gives a little jump, pushing back into you, and putting your dick between her muscular legs, trapping it.

"Oops sorry" your aunt said blushing "the soap was cold and it scared me a bit"

"All good" you say, trying to keep your calm.

You're basically fondling her ass the same way as her tits, taking your time so Aunt Heather won't scold you, and before long the water's off. Beginning to move, you hear an "oops" followed by Aunt Heather bending over to pick something that fell. The result of her bending over and you moving, ends with your dick entering her pussy, freezing you into place. It seems like Aunt Heather hasn't noticed yet.
