When the Boyfriend Visits

I'm in college, so seeing my boyfriend is always very difficult. His visits are, sadly, few and far between, making us both insatiably horny. When he comes down for a weekend, we have wild and raunchy fun. He'll tease me all day by rubbing on my calves or kissing down my neck so I'm worked up by the time night falls and we're in my room by ourselves. We start by making out slowly on the bed, getting more passionate. He likes to take off my shirt and bra so my twins  (DDs) are exposed. He loves playing with my perky nipples by sucking, licking, and biting them until I'm writhing underneath his weight, begging for release. Slowly he'll work his way down to my abdomen and slide off my blue jeans and underwear, leaving me completely exposed. He sticks his finger on my clit, making me moan, and then stops. Walking over to my closet, he grabs three scarves from my shoe rack. We're not into heavy bondage, but we both love it when he ties me up tightly to the bed frame. As he ties my hands above my head and my legs to each post, my naked body shivers in anticipation. Kissing me gently, he begins to nibble my nipples while reaching for the six-inch vibrator on my desk stand. He turns it on to half-power and runs it down my bound arms, resting it on my left breast. He rolls it around my nipples, standing straight at attention. As I start to breathe deeply, he runs it down my abdomen and onto my sopping wet cunt. I'm completely helpless as he rubs my pussy with the vibrating dildo. He then starts to strip, verbally taunting me when my vibrator falls and I'm no longer receiving pleasure. "Oh, did you like that?" he sneers, as I beg with my eyes for more. "Does your pussy need attention? Well, so do I!" His boxers fall to the ground and he straddles me, naked, while playing with my breasts. He's standing at his full seven inches and there's a drop of precum at the tip of his shaft. He rubs his member between my breasts and then shoves it into my mouth, moaning loudly. As he moves in and out of my mouth, he moans louder and louder. It gets me hot giving him his pleasure, and he stops for a moment to replace the dildo so we can get off together. After a few more thrusts, he moves backward and holds the vibrator in place with his leg while he fondles my breasts. When he notices I'm on the brink of orgasm, he slows down on my nipples and removes the vibrator. He repeats the cycle a few times until I'm literally begging him to make me cum. He leans down and starts to lick my clit with the vibrator buzzing away while still tugging on my nipples with one hand. This sends me over the top and I'm moaning as I cum hard. He doesn't let up until I've had two or three orgasms, then it's his turn...a different story, perhaps.
