When Lisa recovered, luckily for her, nobody noticed her problem as she looks down to her skirt, thinking about her little brother that was in her panties as she looks at to crotch with a serious expression on her face, Derek was quite tired so he wasn't moving anymore as he tries to rest, Lisa then look around looking for something until she found donut shop close to her, she nods to it as she go to the shop and buyed a box with random donuts, then she walks to her previous destination, when she entered in the bathroom, she check out if there was people in there, by her luck, there was nobody around, she took the chance and close the door behind her and go to the sinks as she puts the box of donuts on it, leaving the bag were her book was on the floor as Lisa then proceeds to lower her skirt to her feet and so her panties, she then found her tiny brother lying in her panties looking up to her as he noticed her serious look on him.
"Eh...Lisa, I really-" try to say Derek fearful to Lisa but he was suddenly interrupted.
"Quiet! You little pervert." said Lisa to Derek with a stern look on her face as she lowers her right hand to Derek.
"No Lisa wait!" exclaimed Derek to Lisa as his giant sister's fingers caught him easily.
Lisa then lifts up her brother to her face, Derek was trembling scared of what Lisa would do to him, but then she lower his body and leave him in the sink, Lisa put on her soaked panties and her skirt, she then look back to Derek who was trapped in the sink as she moves her right hand and opened the water tap as the stream of water fells on Derek's body.
"Ahhh! Is cold!" squeak Derek shivering as he moves his arms to rub his body.
"Good, now stay quiet or I will get very angry with you if I hear a word coming from you, do you understand?" said Lisa in a serious tone as she lower her hands to Derek.
Derek only nods in silence to Lisa, he really don't want to make her more upset than she already is right now, Lisa then as she caught her tiny brother in her hands, she turns his body around as she has a view of his bare back, Lisa's fingers then starts to rubs Derek's body lo clean him of her love juice off, Lisa's fingers moves around the entire body of Derek, she cleans his feet, his hair until she finally clean almost everything of him, except for his penis and butt, Lisa doesn't hesitate as she moves one finger and rubs Derek's rear, pressing her finger in between Derek's buttcheeks, Derek feels violated as his giant sister was touching his anus, but at the same time, he was getting aroused as his penis got erect by this, Lisa then with her right hand, her index finger and thumb to be exact, caught Derek's hard penis and she begin to rub it up and down, Derek cannot see Lisa's face right now while she has his penis in between of her fingers, so he doesn't know what she has in mind, one thing that was clear for him, even if his sister's fingers feels so good, he can't make any noise, for what Lisa told him before, Derek was trying very hard to not let out a sole moan, he really doesn't want to be punished by his giant sister.
When Derek was about to cum, Lisa suddenly stop rubbing Derek's penis as she quickly turn off the water tap and take out her tiny brother of the sink and leave him a side of the donuts box, she look down to him with a smirk while Derek looks to his hard dick, he feels frustrated that Lisa didn't make him ejaculate and leave him with this hard erection, but he can't do anything about it, Lisa then moves her hands and opened the box of donuts, she turns to Derek and caught him in her right hand as she moves her tiny brother and leave him inside the box with the donuts.
"Very well Derek, now that you are clean we can go back home now, I don't want to know that you are playing with yourself in the way or I will punish you understand?" said Lisa to Derek looking at him with a stern and with a serious tone in her voice.
"Yes sis!" replied Derek scared with a squeak to Lisa.
