I just think that the game in the pool could have gotten hotter,
Jennifer could have been without panties on top of her brother-in-law's hard cock, During the game, the brother went to the bathroom and his girlfriend went to get more drinks... So, in the heat of the moment, with the movements and the lubrication of the very excited pussy, the dick starts to enter, the head is already inside Jennifer, so we would have options; she would get up immediately or continue around, letting the dick go all the way in. (the choice would be at the player's discretion). After a while, the MC speaks softly in her ear; "Jenn, get out! I'm almost cumming!" But Jennifer doesn't get up... The Mc puts his hand over her mouth to muffle her moans... At which point his brother arrives screaming; "Jenn, are you still there? Time is up!" Jennifer quickly gets off the still throbbing dick, her brother-in-law almost cums inside her! Ahhhhhh, if I were the screenwriter...
