She moans in need

Sandra's moan as you finish ripping the tee shirt off her tits, tells you everything you need to know about how she feels about your sudden assertiveness.

"Your hands are so strong. Sir." Her hands start to climb to cover herself but you stop her with a sharp command.

"Stop." She immediately obeys and you continue with more confidence, "I want to see these beauties." The blush that starts in Sandra's cheeks extends all the way to her creamy beasts, and you are glad that this is all happening in your well-lit living room so you are not missing any of this. Her fingers open and close nervously by her side as you cup her left tit with your right hand. Both your previous girlfriends had small firm tits that your large hands had swallowed up, but this is a totally new experience. Not only do the mounds fill your hands, the soft flesh spills between your fingers and her large nipple stabs at the center of your palm and hardens even more. Another soft moan escapes her full lips and you tighten your grip even more.

"These fat tits of yours are going to perfect for nursing my child."

"Children." Sandra corrects you with a gasp, "the doctors gave us all fertility meds before they sent us here, I'll probably have twins or triplets, maybe even more." The thought of your seed growing in her fertile womb as her belly and tits swell makes your cock throb.

"Get up here." You pull Sandra up so her knees are straddling your legs and she is facing you with her hands on your shoulders and her breasts brushing against your chin. As you nibble and suck on her magnificent tits, Sandra continues to add to your secret fantasy.

"I don't have any choice ... none of us do," her dark hair brushes against your cheek as she whispers in your ear. "We have to let you use us … our tight virgin bodies are yours to enjoy in any way you want." Another round of kissing follows, once again with you demanding her surrender and Sandra submissively accepting your mastery. When the kiss finally ends you are both panting with need and you can't wait any longer. It doesn't take long to change positions again, this time she is kneeling on the floor in front of the couch and you are standing with your cock bobbing by her chin.

"I've never done this before." It is unclear whether Sandra is still roleplaying or if she is warning you not to expect too much, but she's clearly not trying to stop you because before you can respond she has the head of your cock in her mouth and her hand is stroking the shaft. The combination of her mouth sucking away and her small hand spreading the saliva dripping from her lips along the shaft has you getting close much sooner than you would have liked.

"Use your tits." You gasp hoarsely, and thankfully Sandra understands what you mean. Her plump D-cups are more than enough to encase your shaft and as you pump in and out of the slick warmth created by her breasts pushed together by her hands, she licks at the tip each time it emerges under her chin. If Vivian could see you abusing her roommate like this there would be Hell to pay, but at the moment both you and Sandra are too far gone to even care.

"No! Not like this, Sir." Sandra gasps when she senses you are about to cum, "I need your semen in my womb, we can't waste it like this." Remembering her initial condition, you guess that she doesn't really mean that and with a grunt you start spewing into the gap between her tits, the **** of the jet shoots all the way through and sprays up into her face several times before you finally stop ejaculating. Once again, your old tee shirt comes in handy as you use it to gently wipe away the thick strands of white goo from her face, neck and tits.

"I'm sorry, Sandra." Too late, you realize what you've just done. "I didn't think it would go that far..." This is someone that you really like and you just fucked her tits like she was a cheap whore.

"You were supposed to inseminate me." Sandra teases from her knees, "I guess I'm just a complete failure..." Relieved to see that at least she's not pissed at you, you help her to her feet as you wipe away the worst of the mess. "It's OK, Stephen. I'm just going to go get cleaned up." Her eyes sparkle as she heads for the bathroom, clearly quite satisfied with herself. "Shall I send in the next girl as I leave?"
