Mantis and Groot fight.

Recently Groot has been acting slightly off due to it being normally mating season for his kind but he’s the only one of his kind so he just has to wait it off.

Groot also body adjusts for this time period as he slowly grows a large thick 15 inch dick…

Groot wanders the ship while him and Mantis wait for the others as they were on a mission, “ugh, look Groot i understand that this is a very specific uh time for you but could you please cover up” Mantis says annoyed.

Groot responds with obviously I am Groot aka no. “Groot please just do it, It’s not like you are going to use it” Mantis rolls her eyes but suddenly Mantis gains a premonition.

She freezes up, “uh Groot- wait think before you-“ She is quickly interrupted as Groot grabs her ripping apart her pants exposing her naked ass.

Mantis eyes widen madly as Groot thrusts his entire length deep into her pussy, “AAGh! Agh~” Mantis groans and moans feeling the length enter her, the size and texture being overwhelming.

She grits her teeth as he thrusts in and out, her ass wobbling with every time Groot slams into her pussy, “ah~ ugh Agh! Fuck~” mantis moans meanwhile Groot shoves his thumb into Mantis’s tight asshole.

“Ah~ not that hole- you stupid-“ Mantis moans even louder as groot’s thumb grows longer pushing deeper into her.

Mantis begins to squirt all over the ground as groot thrusts in and out of her. Groot finally eventually pulls out realising a sap type liquid all over her.

…

Peter, Rocket, Gamora and Drax eventually return from their to find her lying on the ground with her ass out and covered in the sap, not to mention splinters…
