Another tentacle slides out from the wall, this one having a slit in it, almost like a pussy. It immediately slams down onto her dicks, enveloping it in warm, rubbery, somewhat slimy flesh as it squelches and slurps around, getting her dicks in to the base before starting to bounce up and down.
The tentacles in her ass and pussy pick up the pace, slamming into her faster as it drives her closer and closer to an orgasm.
She hears a sudden yelp, and the next thing she knows, Alex is above her, completely naked, his dicks dangling down. The tentacles lower him a bit so his dicks are between her breasts, and then before he can protest, slam two vibrating tentacles into his ass, which makes him buck his hips forwards, fucking her tits as the tentacles fuck him.
