Pretty good offering.
As has been said before the progression is jumpy at times. Going straight from the kiss to shirt off was a bit abrupt, could have done with a Caress Thigh, or Stroke Hair, or similar.
My only other comment, thus far is continuity. When leaving the Clothing Store Larissa is wearing a very nice Pink Suspender Belt(Garters) and a pair of Stockings(Nylons) but in the movie clip that follows she is naked. Did she take them off? Personally I would have preferred she kept them on, either way they just vanish without explanation.
I'm off now to find the elusive threesome ending
