Back to the summer school - part II

The second part of the very important comics, specially created to introduce MMF and related sex actions (like DAP or 'double anal') without NTR content (regarding the MC); some viewers may accept it as adding a cuckoldry, although it's not quite the same.
The comics itself carefully created and will be interesting to the adult comics fans.
No incest in it as I cannot see how to add incest w/o NTR.
