If penis and pussy are connected for a long time, won't you lose track of the boundaries? I can't even tell if the semen dripping down my crotch is yours or your sister's. Two people's pussy juice, two people's semen, and we've orgasmed more than 10 times, so we're perverted creatures. We are lower creatures whose only brain is to do Hamehamedopyudopyu, but we who only have sex are butchigi.
