"It's a strap-on dildo," I said. "I bought it this afternoon." I took the device out of its bag and handed it to Ruth. I'd had to go to three "adult" stores before I found what I wanted. Most of the strap-ons I saw were either flimsy vinyl contraptions, or they sported dildos so huge they would severely damage any normal-sized woman. This one came with a sturdy, comfortable harness and a pink dildo of human proportions. LARGE human proportions, but not life-threatening. It was even shaped like a penis, with a fat glans and the suggestion of veins molded into it. "How does it work?" Denise asked, fascinated. I had her kneel on the bed and began fitting the strap-on around her hips. The base of the dildo was attached to a triangular pad that fitted over Denise's mons, covering her pussy. One thin, soft strap led from the bottom of the triangle between her legs and up through her ass-crack. I led the other, wider straps over her hips where all three connected to a second, smaller triangle just above her butt-crack. I adjusted the straps until the pink rubber dildo was held firmly in place, jutting out from her groin. Denise pulled the tip of the dildo up to her belly, reaching nearly to her navel. She let go and it fell back, bobbing heavily in front of her. She giggled. "Isn't this kind of big?" she laughed. "Would you believe it's the smallest I could find?" "Hmmm. Wearing this makes me want to go for a beer ... in a topless bar!" she joked. Ruth, too, was studying the pink phallus hanging from Denise's crotch. "Does that work like I think it works?" she asked. "She can actually use that like ... you use yours?" "Yep, that's the idea," I said, "but I've never actually seen anybody use one ... outside of an X-rated movie. It looks real, but it might not work." "Let's try," Denise said eagerly. "If it's no good we can always do something else." "Okaaay," Ruth said cautiously. She moved to the middle of the bed and laid on her back, propping herself up on her elbows to watch. Denise knelt awkwardly between her legs, then leaned forward, guiding the fake phallus with one hand while leaning her weight on the other. Ruth reached between her legs to help guide the dildo and Denise suspended herself on both arms, eager to push. "Ready," Ruth said breathlessly, and Denise began pushing, but with little effect. They changed position slightly and tried again. "Stop," Ruth gasped after half a minute. "It won't go in. I don't think I'm wet enough." She blushed. Amazing, I thought. A woman she barely knows is trying to push a rubber penis into her most private opening, and Ruth is embarrassed because she isn't wet enough. Her attitude truly HAD changed. "I think I can help," I said, nudging my way between Ruth's legs. Denise scooted aside and I leaned forward, sliding my hands under Ruth's buttocks. I lifted her hips and eagerly descended on her pussy, hungry for her taste, smelling her sex. I nuzzled through her pubes to kiss her thick outer lips, then darted my tongue between them. I found her opening, then slowly traced my way up her channel toward her little bud. Ruth was up on her elbows, watching me closely, panting quickly. I avoided touching her clit on the first pass, circling it instead and sliding my tongue back down her slit. There I thrust into her hole as deeply as I could. Ruth rewarded me with a quick gasp and tilted her hips up. I began to slowly tongue-fuck her pussy, caressing the sensitive tissues around her opening, then thrusting deep inside. The sensations became too much and she fell back moaning, her hips thrusting. I extended my arms along her sides and took hold of her breasts, gently rolling her hardening nipples between my thumbs and forefingers. She gave a long sigh. I tongue-fucked Ruth for several minutes, pausing occasionally to suck gently on her labia, and her arousal built steadily. Finally I slid my tongue to the top of her slit where gave her clitoris three long, slow licks. The effect on Ruth was electrifying, at least judging by her deep, hoarse groans. Then I sat up. Her legs were spread limply, as wide as they could go, her pussy shining wet and open. "I think she's ready," I said to Denise, picking a pube off my tongue. Denise moved eagerly between our lover's legs and fitted the head of the dildo into her opening. She leaned forward and the fat head suddenly popped inside, prompting a sharp, "Oh!" from Ruth. The shaft gradually disappeared until it was fully inside Ruth's pussy and the pad covering Denise's pussy was pressed firmly against the larger woman's crotch. Ruth's eyes were open now, staring up at Denise's face inches above her. "God, baby, that's so BIG," she panted.
