Once Bart and Lisa were inside they told Marge that they were going to study in the tree house, the 2 lovers then climbed up the ladder into the tree house and once both inside started making out. They would stay there for the next hour making out until they heard a noise.

" What was that? " Bart said

" I don't know let's just continue making out. "

What they thought was just a noise turned out to be Milhouse climbing up the ladder, after seeing what he saw in the tree house he almost wet his pants.

" GAH! "

" Milhouse what are you doing here? " Lisa said giving him a dirty look.

" Coming over to hang out and why were you guys kissing? "

" We are a couple now and don't you tell anyone about this. " Bart said in a serious business tone.

" But why can't I tell anyone? "

" Because we are siblings and siblings dating is wrong. " Lisa said annoyed.

" Do your parents know? "

" NO! " Bart and Lisa said in unison.

" Okay I won't tell anyone. "

" Great now can you go? We would like some privacy. " Lisa said

Once Milhouse was gone the 2 cuddled up together in the corner. It was already nightfall and Lisa had her head resting on Bart's shoulder with his arms around her enjoying the warmth provided from her loved one. Bart saw a shooting star go by and told Lisa to make a wish.

" I wish we wouldn't be considered freaks for dating each other. " Lisa said in a hopeful tone with her eyes closed, imagining what it would be like if they didn't have to live in fear of discovery.

" Nice Wish " Bart said

" Hey Bart it's getting late we should head in before mom gets suspicious about us. "

" Yeah your right plus I'm tired anyways. "

The 2 then went inside and told each other goodnight as they headed to their rooms.

Bart woke up the next day and decided that since it was Saturday he and Lisa should go out and do something. After eating breakfast he told Lisa his plans, then told Marge they were going to the park for the day, and went out.

They decided that the first thing they would do is go to the Kwik•E•Mart to get some squishies then go to Lard Lad Doughnuts. After that they went to Lake Springfield where they skipped rocks into the lake and then biked their way up the surrounding mountains to see the nice view of downtown Springfield. Lastly they went for a romantic walk in the park holding hands at sundown.

The 2 found a bench and sat down nuzzled up against each other looking up at the stars.

" You know Bart I had a really fun time today, best day of my life. " Lisa said

" Yeah I knew you would like it. " Bart said

As the couple embraced in a passionate kiss, a familiar vehicle pulled up and Marge got out looking furious.
