Finally, he stopped in front of the closed door, where the noise was coming from, and leaned closer to listen.
*Hahh* *Hahh* *Hahh*
He recognized that sound! It sounded just like the noise that would come from the woman whenever she was getting fucked by someone.
"Ahh... Ahhh... Yes!"
Wait! That voice belonged to Amara!
Without a doubt, that moan was hers. He'd recognize that tone anywhere. And the pants too—they were definitely coming from her mouth. No question about it. Amara must be having sex in there right now.
'But when did my sister come back? Who was she fucking? Is it her boyfriend?' Oliver thought to himself. 'Instead of coming with us for a weekend vacation, Amara had gone on a trip with her university friends. She was supposed to stay away for a few more days. I guess they ended the trip early or something.'
The image of his sister naked, with her legs spread wide open, getting pounded by some unknown guy, appeared before his eyes. 'No! Why am I thinking about her like this? She may be hot, but she is my big sis. Besides, she must be fucking her boyfriend right now, so I shouldn't get involved. I don't want her mad at me for interrupting them.'
Although he told himself that, Oliver couldn't resist peeking inside the bedroom to see who was fucking his sister, if only to satisfy his curiosity.
'Amara has been a tease for me since childhood. It's not like I'm going to do anything with her. But I am interested in seeing what kind of guy would be up to her level.'
With that in mind, Oliver put his hand on the handle and pushed down on the latch. He then opened the door just a little bit, careful to not make any noise that might alert them to his presence. Then, after taking a deep breath and calming down, he leaned forward until one eye was pressed against the crack.
The scene that awaited him was breathtaking. The first thing he noticed was Amara lying naked on the bed with her legs apart and a naked man positioned between them. His cock was penetrating her vagina while she writhed beneath him in ecstasy.
Amara had short red hair, long eyelashes, blue eyes, and a very pretty face, which was now contorted with pleasure due to her lover's actions. She was a beautiful young woman with long legs and large, firm breasts. A perfect figure!
The man wasn't muscular but had a slim build. And yet, despite being on top of her, he wasn't showing any signs of dominance or superiority. If anything, it looked like Amara was leading the whole affair.
Oliver wondered what kind of relationship they had. He couldn't tell whether they were lovers or just friends with benefits. Still, it didn't matter. 'Now that I know it's her, I better leave before she finds out and gets angry at me for spying on her. It's best to let her enjoy her time without interrupting them.'
He was about to leave when he heard the man's voice coming from inside the room. "Amara! I don't think I can hold back anymore... I'm cumming!"
"Ahhh... Why do you always cum so quickly... Ahhh... Just try to last a bit more... I don't want to end without having orgasmed first!" Amara shouted back at him as he thrust into her body.
"Ahhh! I'm sorry! Here I go!" The guy couldn't endure for another minute and gave a few last thrusts, releasing his semen into her hole.
"Damn it!" She moaned loudly and arched her back upwards. Then, she relaxed again as she felt the warm fluid fill her insides. "I hate you, Jack! You should have tried harder! It's not like it's that hard to fuck me long enough to get me off! Fuck!"
"Sorry, Amara, I did what I could. Maybe next time?" Jack apologized, still panting from exhaustion. "I promise that I'll do my best then!"
"Yes, sure. You say the same thing every time, but it always ends up being the same thing. Well, whatever..." She shook her head in disapproval. Then, after he pulled out of her, Amara got up from the bed and began walking towards the bathroom. "Now, let's take a shower together, so you can go back before my family gets here. And don't forget to wear a condom next time! You came inside me again!"
"Yes, I'll remember," Jack answered, following behind her. When they both entered the bathroom, Oliver heard the water begin flowing.
'So that guy's name is Jack, huh. I wonder who he is to her. I'm also surprised that my sister ended up fucking a guy like him. Not that there's anything wrong with him, but he doesn't seem to be able to satisfy her.'
After waiting for a while to ensure that Amara wouldn't come out, he closed the door again and went to his own room. He wanted to take a shower and clean himself from all the sweat accumulated during the intense sexual activity of the day.
Oliver got naked and stepped into the shower stall. While washing his body, he thought about how his sister seemed disappointed by her partner's performance. That was quite strange because she seemed like someone who knew a lot about sex and enjoyed it. It shouldn't have been hard to find a good lover.
'Wait, why am I even thinking of this?' Oliver snapped out of his thoughts, realizing that he was worrying too much about his big sis and the man she chose to sleep with. 'That's none of my business. It's not as if I can help her or something like that. Or maybe I can..."
