It was a bright day Marco and Star are exploring an unknown jungle dimension in search of a gift for Jackie. Star's having a good time exploring while Marco's busy complaining about the humidity, mosquitoes, and spiny plants.

"Star when can we go home this place is way too hot, these plants keep cutting me, and these mosquitoes keep eating me alive.

"Marco you're the one who wanted to get Jackie a one of a kind gift." She said making Marco groaned. While they're walking, Marco saw a strange plant that looks like it's about to eat her. Acting fast, Marco pushes Star out of the way and, rather than be consumed by the plant, the plant sprays Marco with a pink liquid.

"Aw gross, I knew coming here was a bad idea." Marco groaned in a disgusted tone by the plant's actions.

"Can we go home Star, so that I can take a shower and get this crap off?" Marco requested as he pulled out his scissors and opened the portal.

"Hey, your the one who wanted to find a gift for Jackie." She said

"Well I made a mistake, now let's go." He said

"Fine killjoy." Star said as she walked passed him and entered the portal. After they get home, Marco noticed that Star started to act weird around Marco (Weirder than usual).

"Uh, Star what are you doing?" He asked as Star was smelling him and invading his personal space.

"Sorry, Marco but you smell so good." She said.

"Well I feel gross I need to take a shower." He said as he took off his hoodie and left to the bathroom as she entered the bathroom. Star grabbed his hoodie and sniffed it as her eyes revealed little hearts.

"I want more." She said as she took off her clothes and making her way to the bathroom.

Meanwhile

While taking a shower to wash off the sweat and plant juice, Marco heard the door open.

"Uh someone is in here." Marco said as he heard the door close.

"Uh Hello?" He was then surprised when Star, his best friends, enter the shower and joins him.

"S-Star what are you doing here?" He asked. Star then wrapped her arms around him.

"What I need to get clean too, and this seems more fun." She said as she kissed him. Marco then pulls her away.

"Star what are you doing, we can't do this! I-I'm with Jackie." He said

"Shh. I know Marco just let this happen, It'll be just this once Marco." She said as she captured his lips again.

"Unless you want more." Marco then felt his cock get hard and go in between Star's legs.

"I take it as a yes." She then started rubbing her pussy lips on her shaft. Marco then moved his hands to her hips and moved her himself.

"Glad you finally came around." She said as Marco moved his hands to his back and grabbed her wings, making her moan.

"Marco, I want to taste you." She said as she got down on her knees and sucked on Marco's dick while massaging his balls with her hand.

"Oh God Star that feels so good." He said, Star then smirk and turned him around Star then spread his cheeks and started licking his asshole while licking him she also milked him.

"Oh God Star i'm cumming!" He said Star then got under him and wrapped her lips around his shaft and swallowed his cum. Star then got up and turned off the shower.

"Let's takes this to my room." She said as she stepped out and wrapped a towel around her, leaving the room. Marco then began thinking should he do this.

"Sorry, Jackie." Marco said as he followed her and found her sprawled on the bed with her legs wide opened and her arms out. "Make me yours Marco." She said as Marco walked in and shut the door he climbed on top of her. The two kissed one more time before Marco started kissing down her neck to her breast and started sucking on them making her moan.

"Oh god, Marco that feels so good." She said as she sucked and pinched her nipples he then switched. He soon let's go and moves down her stomach and to her wet quivering pussy.

"Marco, please take your time there." She said with a lustful gaze. Marco then started to suck on her clit while fingering her.

"Oh god, Marco!" She moaned as she massaged his scalp. "Marco, please don't make me wait any longer, I want you now." She said, Marco then aligned his dick with her pussy and pushes it in breaking her hymen.

"Star…"

"Fuck me, Marco." She said as she wrapped her legs around him. "Make me into a woman." She said Marco then moved his hips in and out of her moans filled his ears.

"Star you feel so warm and tight." He said as he pushes deeper into Star.

"Faster Marco, FASTER!" She said Marco then moved his hips faster while staring in her eyes. Star then moved him to his back and got on top of him.

"My turn Diaz!" She said as she began moving her hips up and down taking Marco's whole shaft into her.

"Star i'm cumming!" He said Star then lifted her hips up and slams down, making him cum deep inside her.

"Star… That was incredible." He said.

"Who said we were done." She said as she grabbed Marco's dick and started stroking it. Star then got and turned around, she then pulled her ass cheeks apart and touched the tip of his cock to the ass, she then forced herself down, she moaned as she moves her hair to give him a good view. She then moved her hips up and down, making Marco moan.

"Star it's so tight!" He said as he gripped her hips and forced her down deeper.

"Oh Marco, this is so good." She said as she speeds up.

"Star i'm… AHHH!" The two then cummned simultaneously. Marco cock popped out letting his cum leak out of her ass.

"Star that was incredible." Marco said Star then kissed him

"I'm glad you loved it." She said before she falls asleep in Marco's arms, leaving Marco to wonder.

"What's gotten into her but he is glad it was over, right." He thought before passing out from exhaustion himself. But what neither of them realized was that right outside the door, they were being watched.
