Long enough for him to cum twice!

You moaned as you eased your cock all the way into your dad's well-lubed channel, his internal walls gripping you nicely, once you felt your abs bump up against his fleshy buttcheeks, you started moving slowly, backwards and forwards, establishing a good rhythm. Your dad whimpered as you fucked him, but he didn't wake up, his moans only got louder as you brushed over his prostate.

You were really getting into it, enjoying the feeling of having someone lying helpless beneath you when suddenly you felt your dad's hole clamp down on you as he whimpered out his release, his cum splattering the plastic sheeting you had the presence of mind to place down before you started fucking him.

You paused for a second to allow his asshole to relax again before recommencing your slow, tortuous fuck session. You smiled as you looked down on your passed-out old man as his asscheeks rippled with every thrust you gave him, the sound of them smacking against your rock hard abs on every stroke was making you so happy you went down this route. You smiled as you got into a faster pace, thinking about all those students at university that you'd fucked into oblivion, even before the need for some to have the Daniels injection, you remembered those times fondly because it allowed you to build up your staying power, more than one student had begged you to cum because they were exhausted.

This time however, you didn't want to take too long fucking your dad just in case he did wake up to you **** him, so you aimed your thrusts at his prostate, the one area guaranteed to make any man get close to cumming. Within seconds you felt your dad start shaking, his moans and whimpers were getting more breathy, your dad let out one last whimper before you heard another splash as more of your dad's cum hit the plastic. Lubing up the buttplug in preparation, you started to hammer your dad's asshole, the tightness helping you get closer to orgasm, when suddenly you pulled your dad backward and buried your cock as deep as you could, kissing the entrance to his cervix before (silently) letting out a moan as you felt your scalding hot cum flood your dad's womb. Acting quickly, you slowly pull out of your dad's hole and replace your cock with the buttplug.

Standing your dad back up, you lift him up bridal style and place him on his side of his double bed before cleaning his cock and balls with a wetwipe, placing that on the plastic sheeting before clearing that off the bed, after you took that back to your room, you went back and picked up your clothes before tucking your dad into bed with a kiss on his forehead.
