I slide my tongue over the tip of your cock and then envelop the head, sucking like a greedy slut I can feel it growing in my mouth. You put your hand... on my head, guiding me up and down, sucking the shaft, making it harder while i massage the base of your cock and balls. I can feel it twitching in my mouth and you are calling me lots of names, encouraging me to be a good cock sucking girl! You want it rock hard ready for when it goes into my ass which is soon.You tell me to get up and sit on. I gently grip it between my teeth and give it a light tug. She gasps, so I follow it up with a quick flick of my tongue which grazes her clit."Fuck yes!" Her hand fists my hair.I do it again, and at the same time thrust my finger inside her."Don't you fucking stop, Jack! Don't you dare," she pleads. I grin, she knows me too well.I pull back but keep my finger still sliding in and out of her. I can feel it gripping me tightly. She's so close to cumming. I fucking love it when she gets like. I received two letters from mom and four letters from Mel. Now she tells me how much she cares for me and how she will miss me. I didn’t know if she was just being nice or if she really meant it. She had written me a letter at least every other week. When I received the next letter she told me she was going to college and take up nursing. I do have to admit it felt good getting letters from Mel. I often thought back and wondered how life could have been different if we would have just talked. It was clear from the fullness of her spectacular nipples that she was definitely enjoying this attention, but she seemed increasingly apprehensive, perhaps because she was enjoying it. David was eager to do the deed but, as he mounted her, she gave me an imploring look, causing him to momentarily hesitate. I gave them both what I hoped was a reassuring nod, gently parted her labia, and heard her gasp as he entered her. He began rhythmically thrusting and, as their bodies began to move in.
