The next day

You saw Samantha the next day and she smiled and waved at you as you sat in the math class. You sat and struggled not to get an erection remembering Samantha's soft curves. As class came to a close she came over to where you were sitting. "So, I didn't understand any of that, I am definitely going to need your help tonight." She says as she smiles at you. You stare at her in confusion. "O-ok, ill see you tonight."

The rest of the day flys by in anticipation and you soon find yourself outside Samantha's house. You knock and wait for a bit before an unfamiliar face opens the door. Greeting you is an adorable little korean woman wearing a robe. Short cropped black hair in a boyish cut frames her round face. "Oh, hi, you must be John, come on in." She greets you warmly. You wander inside and are ushered into Samantha's room. She glances up at you as you enter and smiles before getting up and kissing the girl in the robe. "Thanks honey, John and I are going to be having sex and studying math tonight. I really need the help." You gag at her admission and the girlfriends warm smile in response. "You don't mind if I stay in here do you? Ill be quiet."

You sit down on the bed as Samantha starts to strip right in front of you. "So," you begin "Thats your girlfriend?" Samantha glances up at you as she finishes pulling her shirt off. "Lindy? ya, we've been dating for nearly two years." Turning to Lindy you wave your hand towards the nearly nude girl. "You are ok with this?" She just smiles "Oh, I am more than ok with this. I could watch at Samantha all day." You stop for a moment. "N-no! I meant with Samantha having sex with me." The girl in question has moved onto tugging at your pants.

Lindy looks slightly confused. "Ya, you made a fair trade with her. You help her with classes, she has sex with you." You absentmindedly pull down your unbuttoned pants. "So, what would be a fair trade then?" Lindy just shrugs. "I don't know. depends on the deal." You pause for a moment as you feel Samantha take you in her mouth and start slowly sucking and bobbing her head on your shaft. You eventually regain your senses and turning to Lindy ask. "So what, If I clean all the dishes in your sink you will agree to be my sex ****?" you ask incredulously. Lindy seems to think about it for a moment before responding. "Sure, that seems fair."

You stare at lindy for long enough that Samantha releases your cock with a faint pop and reaches up to pull your face down to her naked form. "So, you wana get a condom or are you just gonna stick it in me again?" Samantha climbs onto the bed and wiggles her cute ass at you from all fours. You cant take anymore and quickly climb onto the bed and burrow your cock into her. Samantha squeals at your sudden attack. "Goodness, it is just as big as I remembered." she moans as you piston into her. Glancing over at lindy you see her gently rubbing herself through the robe as Samantha moans under you. "You gonna -mhh- cum inside me again?" Samantha moans as you ram her. Grunting you simply speed up even more. "Ill take that as a yeeeessss." She mumbles as you slam into her. Finally you cant contain it any more and slam your hips against her as you release a flood of cum deep into her pussy.

Samantha pants under you as you feel yourself slowly deflate inside her. "Goodness, you must really want to knock me up." She says with a laugh. "Today is definitely a dangerous day, ah well." she says nonchalantly. You see Lindy quivering in her chair nearby as Samantha starts pulling papers out of her bag and you get down to your half of the deal, helping her on the math problems. She doesn't really need you to help her, she almost had it. She quickly blazes through the problems alongside you. As you finish you stretch and start gathering your things.

"Aren't you going to do the dishes?" you hear Lindy say as you zip your backpack up. Shrugging you decide it couldn't hurt to humor her. You all wander into the kitchen and you look at the few dishes in the sink and scattered around the kitchen, gathering them up you start the water and scrub away at some kind of dried spaghetti. (what kind of monster doesn't rinse their plates?) As you finish the last plate and set it in the drying rack Lindy speaks up. "Thank you for doing the dishes, M-master." You turn around to face her and are met with her beautiful porcelain skin showing from the robe that she is now holding open. Her modest breasts are topped with erect nipples, and your eyes wander down her body to her glistening pussy. A blush creeps across her cheeks as you ogle her. "What would you like me to do master?"
