"My sister's here…" Lucy spit out Steve's "little brother," wanting to stop, knowing her own sister was not far away . The thought of the shame and embarra.s.sment she would feel if her sister found out that she was cavorting with Steve was overwhelming—she'd want the earth to swallow her up .

"Keep quiet!" Steve suddenly held onto Lucy's tiny head and stuffed his "little brother" forcefully inside her mouth, plugging it up . This also hid his phallus in her mouth .

"Mmmph…" Lucy shouted, but her mouth was blocked up by Steve's "little brother," not letting her speak .

"If you continue making noises, we'll be heard by Sofia and Stuart," Steve lowered his voice and said . But then his lower body moved back and forth of its own accord, his "little brother" entering and exiting Lucy's mouth . A stirring sensation he'd never had before caused Steve to be even more aroused, and his member grew bigger and longer .

He thought back upon Sofia's arrogance back when they were allocating team members . She would never have thought that her precious sister would be blowing his "little brother" under his belt, her mouth used as he pleased . Steve got more excited and pressed down on Lucy's head, moving in and out . Lucy no longer dared to make any noise, she was so afraid that her sister would discover them here . But thinking of Sofia not far away as she was doing unspeakable things filled her with contradictory feelings of shame and excitement . She felt roused and sensitive .

Steve was still following Sofia and Stuart's movements with his eyes . They blasted open a main door and a group of three-eyed cat beasts came pouring out, standing on their hind legs, weapons in hand . They charged towards Sofia and Stuart, both of whom were oblivious to the fact that Steve and Lucy were performing s.e.xual acts in the next building .

Steve put his hand inside Lucy and felt her nether regions sucking on his middle finger, the fleshy walls squirming around . They clamped on his middle finger tightly, as wanting to swallow his whole hand . If not for the terrible timing, Steve wanted to push down Lucy's body and insert his "little brother" inside her . He would hump the h.e.l.l out of the beautiful girl in front of him, riding waves of pleasure . A long time pa.s.sed before Sofia and Stuart finally managed to eliminate all the devil-eyed black cats . At the very moment they did, Steve finally shot out all his pent-up l.u.s.t .

"Aaah!" Steve growled and penetrated her mouth deeply as he held onto Lucy's head, reaching all the way into her throat . Half of "little brother" was swallowed . s.e.m.e.n kept shooting out and Lucy could not move; she could only force herself not to gag as she swallowed Steve's s.e.m.e.n bit by bit . Right at that moment, Sofia below looked in Steve and Lucy's direction .

"Sofia, what's the matter?" Stuart asked .

"I heard a noise coming from there . " Sofia pointed in Steve and Lucy's direction . Stuart's gaze followed suit as he glanced at his scanning appliance and said, "The life radar shows that there's no one there . " Sofia's dainty brows furrowed . That area was giving her an uneasy feeling .

"Sofia, we don't have much time . If we don't get the treasure before Collic returns, neither of us will get out of here alive . Let's hurry," Stuart said . "Besides, we're the only ones who know where Collic's experiment lab is . No one else would be here . " They were short on time, so Sofia could only suppress her doubts and follow Stuart into the tunnel .

On the other side, Steve had managed to avoid Sofia's gaze and heaved a sigh of relief . He removed his "little brother" from Lucy's small mouth . Even though he had just come, his "little brother" was still energetic and hard . Lucy laid back on the soft mat and gasped for breath, a string of white s.e.m.e.n hanging off the corner of her mouth . The two of them cuddled affectionally before putting their clothes back on, but Steve took away Lucy's soaked underwear and this caused her quite a bit of embarra.s.sment . But Lucy's powerful level of cell activation quickly allowed her swollen lips to return to their normal state .

"The both of them haven't returned yet, let's go down and take a look," Steve said .

"I did not expect this experiment lab to be here, right in front of us!" Lucy exclaimed . The entrance to the lab was covered by a huge board . It was no wonder that they could not find it at first . The two of them waited for a while, but they did not sense any activity underground .

"You wait out here, I'll go down and take a look," Steve said . Lucy had just had her first s.e.xual experience and had not gained back her full strength . Besides, the situation inside was unclear and one of them needed to stay outside in case of trouble . Lucy nodded her head, and Steve entered the underground tunnel .
