Have sex, of course

When they arrived at the school, as expected, all the students were in various forms of undress and engaging in lewd acts. There was pair of boys with their shorts down, whacking off onto a girl with glasses carefully reading a book: as Jenna and Michael walked by, one of them spurted large globs over her hair and thin shirt. A few moments later, he came again, a splatter landing on her face and dripping down between her breasts. She paid it no mind. A boy was in the process of depantsing a girl (well, de-panty-ing), who then chased after him playfully. An unidentified teacher was leaned over, dick hanging down, as a shirtless boy ate his ass out.

"Over here's good."

Michael was suddenly pulled over by Jenna, who quickly positioned herself on an empty table, spreading her legs. He hesitated.

"Come on now, fuck me!"

He felt drawn in, his penis already ready for the challenge. The insertion was easy, aided by the girl's copious vaginal fluids, which were already dripping onto the seat. It seemed girls never stopped lubricating themselves, he thought, noting the sticky trails down her legs.

As they two began their intercourse in the open plaza, Michael tried his best to read Jenna's rhythm and match it. He was worried: after all, if everybody had sex so often, they were probably pretty damn good at it, and would expect the same of him. Thankfully, she seemed to be enjoying it, her eyes closed as she tried to enjoy his member.

This continued for several minutes, with an interlude as Jenna changed positions to doggy-style, and taking control of the thrusting.

The rutting couple was getting closer, when suddenly Michael felt two slender hands reach under his shirt and pinch his nipples from behind.

"Gahh!!" The surprise pushed him over the edge, and he unloaded a thick load directly into Jenna's pussy.

"Got ya!" came the voice from behind him. Jenna was giggling as Michael pulled out, sticky cum immediately drooling out.

It was his sister Tabitha, standing there naked with her hands on her hips, smiling wide. Well, not completely naked: she had knee-high black socks, with numerous aged white stains on it.

"Heheh, how was Jenna?" She was absentmindedly stroking herself as she talked.

"Ahhh", Michael began, still not fully recovered. "Really good, uh, as usual."

"Well, I couldn't find you this morning, so I had to have breakfast without my morning blowjob," Tabitha stated matter-of-factly. With that, she pushed me against the nearby pillar and got on her knees.

Jenna was playing with her creampie while filming with her phone. (Michael didn't notice it before: where was she keeping it?)

Tabby stroked my already-hard cock with her tongue several times, before pushing the whole thing down her throat. She was absolutely a professional -- although she did mention this was a daily thing. The way she pulled her his cock along her throat seemed to hit the head of his dick in all the right places. This is bizarre, he thought, my sister is going down on me with such knowledge of weakspots I didn't even know I had.

He noted Jenna had since abandoned her video: she was engaging in a 69 with an unknown girl with gusto.

Michael felt himself getting closer, but apparently breaking from routine, Jenna pulled her mouth off, a trial of thick saliva drooling down between her petite breasts. Without giving him a second to react, she had turned herself around and skewered herself on her brother's member. With practiced ease, she controlled the rhythm of their incestuous exercise, soon leaving her brother with ****. He groaned as he shot his second load within ten minutes, this one somehow larger than the first.
