1. those weren't drugs, it was viagra. hiroto implies he was going to take them himself but apparently reading comprehension these days is very low.
2. the first time was in fact rape or at the very least rapey whichever makes you feel better ig. it isn't a realistic depiction of rape; don't ever come into a porn manga and expect realistic tbh. it doesn't bother me but i could bother others, so yes, i can say, there was non consensual sex acts.
can i stop being baited into thinking stories will end in a polyam relationship bc that shit hurted
