Ironically, right after she says that the beasts' boy grumbles loudly in excitement, surprising both of them.  Of course this also means he now makes his move, firing his tentacles like streamers around her.  Before she has a chance to even turn around, his arms wrap around both her biceps as well as her thighs.  More fly out in rapid succession, as he restrains her, testing how much force is actually needed to do so(he must be careful not to rip her apart).  They wrap around her waist with tightening force as he pulls her into his soft body.  Figuring that he has successfully captured his new victim, his body erupts in pure bliss, spurting sticky, viscous fluid out of all his appendages everywhere, especially on Andrea.
