2Hi Laguners,
i´d like to recreate the setting of HA3, so we got the villa and the pool (for later scene) in backyard all in party decoration of course.
guests: wendy, cloe, nany, frank, piano teacher (HA1), kenny + mum (she was hot

) maybe sb brings a friend from polonesia...
1st part: late afternoon (thats why its called HA5)
1 scene: lobby of villa/ living room (both rooms kinda open)
meet and greet... piano teacher playing on the grand piano
2 scene: bithday game(s) twister guests move to diff areas of mansion
4-5 ppl start playing pulling other ppl clothes off or not trying to loose their own (stay teasing softcore here)
nany of course will be helping guests with drinks... + checking if everybody is behaving. so you need to untwist and make ppl proper again 2-3 times.
kennys mom seems to be attracted (in a teasing manner) to piano teacher while playing of course.
//(part 4) here could be room for some more or less dirty presents, which could be used in later scenes//
2nd part: evening
party shifts outside to pool area, which is decorated with some pro lighting effects, pool bar, ppl standing around, talking, dancing (hot dancing) swimming...
since nany is around cloe and wendy get in some action in the pool where they are less seen. they ask nany to bring some more snacks from the kitchen to send her away.
kamera goes back inside, where the piano teacher and kennys mom are having some fun on the grand piano. nany on the way to fetch snacks stops by and gets aroused, pleasuring herself.
outside the girls got kenny to join in the pool. to be safe the send frank after nany.
3rd part: finale
inside nany hears somebody coming leaves the piano scene, forgetting her panties, she dropped and moves to kitchen.
frank finds her there and they get it on quickly.
meanwhile outside the fun continues, but in the extasy of love some pool water or better body fluids get onto some cables of the high tech lighting systems, and a power out occurs. nany and frank get interrupted start looking for the fuses. outside the wendy and cloe use the distraction to get their share of pleasure.
Ending: lots of kisses and wet dreams of the day
hope you´ll enjoy my birthdy fantasy, mort
