Yeah i think this is it.
I dont get that impression, we hear a lot of storys about the fun times Allison and MC had and about allie/mc/cooper/cammie shenigans in the past. They always seemed confident and adventerous.
There is nothing slutty about sunbathing topless at a pool with barely anyone around for like 30 minutes.
Some people are really blowing this out of character and behaving like allison gave a stripshow to a crowd of men wtf, its just some titties.
I mean is every women at a nude beach a slut too?
And imo it was believable displayed as Allison is a confident woman but as the other poster mentioned lost the confidence about her body since the divorce or birth or both. Jasmine was just rekindling a flame, she doesnt have the means to "pressure" a confident woman like allison into anything anyway, she just helped her to do what she wanted to to anyway.
And seems like Jasmine is helping Allison to do what she wants to do anyway with the mc too, best wingwoman ever
