Reeling from feeling another load of her brother's cum spurt into her womb, Jennifer confides in herself that she should go to school no matter what. Even though she and her brother, Mike, will be having sex 24/7 now, that didn't mean she couldn't live her life as she saw fit. Not to mention, she started to not want to undo the bonds holding them together; being embraced and filled up by someone like Mike, she really didn't need anyone else. "Ok, bro, here's the deal," Jen told him. "I'll always be yours, and only you will ever get to fuck me. In fact, I want to keep your dick in my cunt permanently. However, since I'm going to be walking us around, I'll still get to live my life. Ok? That means when I want to go shopping, see a movie, stay home, exercise, etc I'm doing them with you along for the ride; absolutely no rebuttals from you." Mike agreed with a condition, "Sure, but as an addendum, whenever I want you to, you're going to wear flip flops. Hearing them is a turn on for me." Jen agrees as well, signalling the start of their new lives.
Worrying about clothing, Jen wears a pair of panties, though thanks to her new body shape, they end up more like a thong. Her black tank top is so tight, it's more like a sports bra. Her P cup breasts spilled out of the top with some lovely cleavage; meanwhile, the black yoga pants she put on, which usually go to her ankles, didn't even get to her knees; seeming more like spandex shorts. Without even listening to Mike request it, she put flip flops on. Wiggling her dainty toes, Jen felt sexy and comfortable; Mike felt even better. Jennifer's tight clothes pressed him even tighter against his sister's voluptuous body. And having his head nestled between her ginormous, sweaty tits was relaxing.
Grabbing her bag, Jennifer left the house, standing at the end of the walk for the schoolbus to arrive. The time spent waiting wasn't wasted; grabbing Mike's hips, the two continued their active passionate lovemaking in public. She was starting to warm up to the idea of always having intercourse. They both orgasmed together once more, Jennifer clenching her toes at from the ecstasy. "I make sure to fill you up completely before the end of the school day." Mike informed her, as he kept moving his hips.
Once the bus showed up, Jen stepped on, having to duck her head since she was now 8 ft tall. Everyone on board was in shock at her appearance, as she stepped past to grab a back seat. Sitting down, she patted her brother's back and reclined slightly, letting him get to work pounding her pussy. Licking her plump lips, she squeezed her thighs together as he came once more. "It's certainly going to be a long day." She sighed, as Mike's screwing didn't stop.
