The rest of the day was uneventful until evening. Tina came home from work and we had dinner. I gave her a backrub on the living room floor while we were both naked. The backrub turned into one of those nice slow fucks. She was apprehensive at first as she was afraid her sister would come home in the middle of everything and surprise us.
"So what?" I answered her concerns. "We're not doing anything she doesn't know we're doing already, besides maybe you'd find you like her watching us."
With that suggestion she squirmed a little and tightened her pussy muscles around my dick. "I don't think I'm ready to perform for an audience yet I need more practice. But it does seem kinda naughty, at least thinking about it."
After we were done we got dressed and sat cuddling on the couch and I made a suggestion. "You only work till noon tomorrow then you're off for 4 days again right"
"Uh huh." She answered concededly.
"You know, I have a friend who runs a motel down in Ocean City. What would you think if I called him to see if he had a room we could get for a couple of days? We could leave when you get out of work and be there by mid afternoon for a couple of days of sun and fun."
She jumped up and squealed "That would be wonderful, I love the beach." But then her shoulders slumped. "But what about Tammy, I wouldn't feel right about leaving her home alone."
"We can take her with us. If I can get two rooms great, if not we just kick her out when we want to fuck. Having her here hasn't been bad. She's OK." I answered.
"Could we?" She asked hopefully. I knew I was gonna get special sex tonight by the look on her face. So I picked up the phone and made the call.
Steve only had one room available, what he called his emergency room. Emergency being a friend or special customer calling at the last minute. So I asked him to hold it and gave him arrival and departure dates. Tina was ecstatic and started rushing around and getting things packed and ready to go. While she was still running around being excited, Tammy came home.
Tina ran up to her and almost knocked her over "How would you like to go to the beach for a few days" she asked her sister.
"Oh God I would love it. But we can't go. We couldn't afford it and we would never get a place to stay on short notice." Tammy answered.
"All taken care of. We leave tomorrow at noon when I finish work. That is unless you want to stay here alone?" Tina said acting nonchalant.
Tammy stood there looking at her sister trying to be certain she was serious. "You're serious? We're going to the beach!" The two sisters hugged and screamed in joy. Then Tammy broke from her sister ran over and threw her arms around me. "I know you did this Thank you!" She said as she laid a lip lock on me.
"Hey! My guy! You get what's left after I'm done Sis." Tina said as she playfully pulled her sister off of me and dropped into my lap to give me a kiss. "You can find your own at the beach."
They spent the rest of the evening being excited and getting things packed. We all went to bed around 11 PM. While Tina was in the bathroom I softly told Tammy. "Go slow tonight so I can watch you. Hold your orgasm till after Tina is satisfied."
"From what I've seen that might be sometime around sunrise" she quipped with a smile.
Tina and I started our usual play, first with me running my tongue over her gorgeous nipples and slowly finger fucking her till she came.
She was so excited about the upcoming trip she dropped down for a very special blowjob. She worked me starting by running her tongue up and down my shaft and then slowly drawing my dick into her mouth. First just the head and gently sucking and swirling her tongue around the head. Then driving down and swallowing my entire length until her nose was buried in my pubic hair then drawing back out very slowly. She kept this up for a half hour.
Every time I would start to get close to blowing my load she would ease off and let me come down. She had brought me so close so often that I got to the point where I would have a hard time cumming when I was ready and she sensed my state. She slid her body up mine and squatted over my dick and let my member slide into her dripping pussy. Now she slowly pumped her silken wetness up and down on me. Impaling herself on me repeatedly. Throughout the blow job and now the slow fuck I watched in the mirror and could see Tammy slowly diddling herself, working up to an orgasm.
I watched as she pinched her nipples with one hand and at the same time slid a finger up into her pussy, then drawing it out and running the wetness over her nipples and then back to her pussy. Continually repeating the process. All the While Tina was riding my cock.
Then I got a surprise. While she was riding my cock Tina looked at me and out of the blue asked, "Would you like to fuck my ass. I need my ass fucked tonight. You have me so hot."
We had never gone to anal sex in the time we were together and I will admit that it is not something I usually get excited about but every once in a while I like to stick my dick in a Hershey Highway. Tonight was one of those times. The thought of sticking my dick in Tina's asshole while her sister watched really turned me on.
