Stella secretly has an infatuation with Ama’s armpits, so she has secretly stolen a few of her used dirty sweaty gym t-shirts so she can sn*ff the underarm area and experience Ama’s armpit scent.

The scene starts with Stella with a pile of a few of these t-shirts next to her. She pulls one of the t-shirts up to her face and starts sn*ffing the underarm area, and she notably gets more aroused. Almost as if she is going feral with lust for Ama’s pheromones, taking deeper and deeper sn*ffs of the shirt, rubbing it over her face, starting to sn*ff her own armpits, and eventually even rubbing herself.

But meanwhile we see Ama show up in the background. First she arrives casually as if she came to ask Stella a question, but then Ama notices that Stella is being naughty with her own missing t-shirt so she stands back and silently observes what Ama is doing. Stella does not realize Ama is there yet.

Once Ama realizes what’s going on, she starts off shocked with an angry expression. But eventually she gets curious and starts sn*ffing her own armpits. Finally we can tell Ama is getting aroused and starts rubbing herself as well as she watches Stella. Eventually Ama puts on a devious smile and wants to escalate things so she coughs as if to alert Stella to her presence.

Stella is flustered that she may have been caught so immediately tries to hide the pile of Ama’s t-shirts (for example maybe stuffing them behind a nearby pillow). Ama starts by pretending like everything's cool as if she didn’t realize what Stella was doing. Ama tells Stella that she just got back from a sweaty workout at the gym and was about to take a shower, but when she went to go find a new t-shirt to wear after her shower, she noticed that a lot of her favorite shirts were missing from her wardrobe. Ama asks Stella if she knows anything about her missing shirts in a teasingly accusatory way.

Stella denies this and tries to play dumb, but is notably flustered. So Ama then reaches to where she saw Stella hide the t-shirts, and pulls one out dangling it in front of Stella’s face as if to escalate the confrontation and say “Well what’s this then”?

Stella tries to play it off with some excuse about how she was just trying to help Ama with her laundry, but when it becomes obvious that Ama knows what’s going on, Stella confesses. She explains how one day she was doing laundry and out of curiosity sn*ffed Ama’s shirt, and she was so turned on by Ama’s sweaty pheromones that she developed a crush on Ama’s armpits and couldn’t help but take some of her shirts.

Ama takes on a dominant disciplinary tone, but with a hint of mischievous excitement herself. She scolds Stella for how naughty and p*rverted it is for her to develop a crush on another woman’s armpits, yet alone her own step-mommy. Ama chastises Stella about how much an invasion of her privacy this is. Stella starts to look ashamed, but before she can respond Ama grabs Stella’s face and shoves it into her armpit.

Ama commands Stella to sn*ff her armpit while continuing to scold her. “If you’re going to steal my t-shirts just for trades of my armpit sweat, you better learn to appreciate the real thing!” Ama even grabs one of the t-shirts and rubs it against her own sweaty armpits to make them even smellier, and she shoves the shirt into Stella’s face while continuing to command her to sn*ff both Ama’s actual armpits and the shirt.

Ama is clearly getting into it, but keeps a motherly disciplinary tone. Teasing Stella for how naughty it is that she loves sn*ffing her step-mommy’s armpits. If you were comfortable with it, I would love if Ama could have a degrading tone and c*ll Stella names like “step-mommy’s armpit sl*t”.

Eventually Stella can’t help herself and darts out her tongue to get a l*ck of Ama’s armpit. Ama feigns anger and maybe even playfully slaps Stella. But she is clearly excited and commands Stella that she better worship her armpits properly. She clamps Stella’s face even closer against her armpit as Stella finally lets loose and goes to town fervously worshipping Ama’s armpits. Sn*ffing them, kissing them, l*cking them sensually but also aggressively. Both Stella and Ama are clearly very turned on with Ama even unable to help herself from some moans.

Eventually Ama is so flustered and turned on that she announces she has to go take a shower. Stella is also flustered and disappointed that the armpit worship had to end, but then Ama changes to a more loving motherly tone and kisses Stella on the cheek calling her a “good girl”. Ama explains that she’ll allow Stella to keep her shirt collection. Ama walks off screen and Stella is on cloud 9 as she starts sn*ffing another one of the shirts as the scene ends.
