Young girl is invited to bisex group gathering

[TellusMoon]

Hi. I am looking for a 2 parts story.
This story is about a young girl (maybe at university?) thay is invited to sex gathering. She doesnt know the people envolved. They are older, composed by 2 women and 4 men. At the living room, in the couchs they starts having fun, mostly in pairs.
The action includes same sex (ff and mm) and also watersports, that she enjoys very much.

In second part the girl returns to sex gathering bringing two friends (or housemates) with her, a boy and another girl.
The 2nd part repeats first one with the other girl also experiencing a lot of new things and the boy being the object of affection of the 2 older and curvier women.

As you are lead into the living room by the hostess in a robe shiwing a bit if clevage, white stockings and high heels, you witness a middle aged woman on her knees in the middle of the room. She has on black nylons, black spiky heals, black lacey push up bra and matching panties. Two men are fondling her hanging boobs and her ass. Two other men sit together on the couch rubbing their crotches watching the scene as they see you enter the room. The hostess drops her robe revealing sexy white lingerie, heads to the bar and pours you your favorite drink. You stand and take in the scene.
